The installation, starting up, and servicing of heating, ventilating, and air-conditioning equipment can be hazardous and requires specific knowledge and training. Improperly installed, adjusted or altered equipment by an unqualified person could result in death or serious injury. When working on the equipment, observe all precautions in the literature and on the tags, stickers, and labels that are attached to the equipment. May 2023 WSHP-SVX014J-EN Introduction Read this manual thoroughly before operating or servicing this unit. Warnings, Cautions, and Notices Safety advisories appear throughout this manual as required. Your personal safety and the proper operation of this machine depend upon the strict observance of these precautions. The three types of advisories are defined as follows: WARNING Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. CAUTION NOTICE Indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury. It could also be used to alert against unsafe practices. Indicates a situation that could result in equipment or property-damage only accidents. Important Environmental Concerns Scientific research has shown that certain man-made chemicals can affect the earth's naturally occurring stratospheric ozone layer when released to the atmosphere. In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing these compounds have the same potential impact to the environment. Trane advocates the responsible handling of all refrigerants. Important Responsible Refrigerant Practices Trane believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry. All technicians who handle refrigerants must be certified according to local rules. For the USA, the Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them. WARNING Proper Field Wiring and Grounding Required! Failure to follow code could result in death or serious injury. All field wiring MUST be performed by qualified personnel. Improperly installed and grounded field wiring poses FIRE and ELECTROCUTION hazards. To avoid these hazards, you MUST follow requirements for field wiring installation and grounding as described in NEC and your local/state/national electrical codes. WARNING Personal Protective Equipment (PPE) Required! Failure to wear proper PPE for the job being undertaken could result in death or serious injury. Technicians, in order to protect themselves from potential electrical, mechanical, and chemical hazards, MUST follow precautions in this manual and on the tags, stickers, and labels, as well as the instructions below: · Before installing/servicing this unit, technicians MUST put on all PPE required for the work being undertaken (Examples; cut resistant gloves/ sleeves, butyl gloves, safety glasses, hard hat/ bump cap, fall protection, electrical PPE and arc flash clothing). ALWAYS refer to appropriate Safety Data Sheets (SDS) and OSHA guidelines for proper PPE. · When working with or around hazardous chemicals, ALWAYS refer to the appropriate SDS and OSHA/GHS (Global Harmonized System of Classification and Labelling of Chemicals) guidelines for information on allowable personal exposure levels, proper respiratory protection and handling instructions. · If there is a risk of energized electrical contact, arc, or flash, technicians MUST put on all PPE in accordance with OSHA, NFPA 70E, or other country-specific requirements for arc flash protection, PRIOR to servicing the unit. NEVER PERFORM ANY SWITCHING, DISCONNECTING, OR VOLTAGE TESTING WITHOUT PROPER ELECTRICAL PPE AND ARC FLASH CLOTHING. ENSURE ELECTRICAL METERS AND EQUIPMENT ARE PROPERLY RATED FOR INTENDED VOLTAGE. ©2023 Trane WSHP-SVX014J-EN WARNING Follow EHS Policies!

Water-to-Refrigerant Coil The water-to-refrigerant coil is a copper or cupro-nickel (option) and steel tube (tube-within-a-tube) design, leak tested to assure there is no cross leakage between the water tube (copper/cupro-nickel) and refrigerant gas (steel tube). Table 1. High/low pressure switch Trip Recover Unit LP 40 +/-4 56 +/-4 psig HP 650 +/-10 550 +/-10 psig Controls The available control type is a Deluxe 24V control option, a SymbioTM 400-B/Tracer® UC400-B BACnet® control option for all unit sizes. All power wiring to the equipment is made at the unit's compressor contactor or optional disconnect switch for the EXH/V 0.75 to 6 ton units and the DXH/V 2 to 6 ton units. For units without the disconnect switch, the power wiring needs to be connected to the screw terminals of the compressor contactor. All low-voltage wiring is made at the unit's low voltage terminal plug. System Input Devices and Functions A thermostat, zone sensor, or building automation system is required to operate the water-source heat pump. The flexibility of having several mode capabilities depends upon the type of sensor and/or remote panel selected. Troubleshooting and connection diagrams for the 24V control systems may be located in the back of this manual. All digital control troubleshooting tips and connection diagrams are located in BAS-SVX065*-EN (UC400-B). Deluxe 24V Controls (option) Units containing the Deluxe 24V control design will incorporate a microprocessor-based control board. The Trane microprocessor board is factory wired to a terminal plug to provide all necessary terminals for field connection. 8 The deluxe board is equipped with a random start relay, anti-short cycle timer, brown out protection, compressor disable, condensate overflow, unit safety control, diagnostics, and a generic relay (which may be available for field use). SymbioTM 400-B/Tracer® UC400B (option) The Symbio 400-B/UC400-B is a BTL Listed BACnet® controller that can operate stand- alone or within a Building Automation System (BAS) such as Tracer® SC+. For installation, operation, and maintenance, see BASSVX065*-EN (UC400-B). Pump Module (Field Installed Accessory) The pump module shall consist of either a single or dual 1/6 HP cast iron pump and a brass three-way shut-off valve. The pump module kits shall contain the necessary components for the installation, operation and maintenance of the water circuit of a closed-loop distributed pumping application. Waterside Economizer (Option) Instructions for mechanical connection of the waterside economizer to the water-source heat pump may be found in the dimensional section of this manual. The waterside economizer is designed to begin economizing mode when water temperatures fall below the field adjustable temperature of 25, 35, 45, 55 or 60°F (for the Deluxe control option), or below the programmed setpoint (for the SymbioTM 400-B/UC400-B control option). When the temperature is less than the setpoint, fluid will flow into the economizing coil, while simultaneously halting mechanical operation of the compressor. Mechanical cooling will continue on a call for a second stage from the thermostat or system control. Entering water temperature sensor is factory provided for field installation on the entering water side of the coil. Boilerless Control/Electric Heat (Option) This option targets building designs that do not incorporate a boiler to heat the loop system. During a heavy heating load, the loop temperature may begin to fall. As the loop temperature decreases, the heating capacity of the heat pump will also decrease. In the heating mode, when the loop temperature falls below 55°F (factory setting), the electric heater is energized, and the compressor is locked out. The system's electric heat source will continue to be utilized for primary heating until the loop temperature rises WSHP-SVX014J-EN above 60°F. Once the loop temperature rises above 60°F, the boilerless controller returns the unit to normal compressor heating operation and locks out the electric heater. For the EXV/H and DXV/H models, the electric heat will be field installed by the contractor. Note: The boilerless controller has a field adjustable entering water temperature setting of 25, 35, 45, 55, and 60 degrees. The compressor operation will return to normal operation when the loop temperature rises 5 degrees above the setpoint. This electric heat option is designed for primary heat only, not to run as supplemental heat to the heating function of the heat pump. Table 2.

The optimum clearance required is 20 inches. Notes: · Return air direction (left-hand or right hand) is NOT field convertible. Units must be ordered with correct return air side. · For horizontal models, be sure to allow enough clearance between the condensate drain and the ceiling to allow for pitching of the condensate line. See Figure 20, p. 31 for pitching requirements. 14" 14" 14" 14" UNIT FRONT 36" UNIT FRONT 36" 12 WSHP-SVX014J-EN 1" 1" Figure 2. Clearance EXVG/DXVG 0.75 to 6 tons 24" 1" RIGHT RETURN TOP/BACK SUPPLY UNIT FRONT 36" 24" 1" UNIT FRONT 36" LEFT RETURN TOP/BACK SUPPLY Unit Dimensions A 24inch clearance from other mechanical and electrical equipment (where shown) is recommended for most unit configurations. This will enable panel removal from the unit for service/maintenance. The 24inch side clearance on EXVG/DXVG 0.75 to 6T models is for optimal access only. Side clearance is not a requirement as most components can be accessed from the front of the unit. A 1inch minimum clearance between the filter rack and any obstacle is required for units in a free return application to provide proper air flow to the air-to-refrigerant coil. A 12inch minimum clearance between the filter rack and any obstacle should be provided to properly attached ductwork. The 1inch dimension shown in the back of the unit represents the supply duct collar for the back supply option. This clearance is needed to clear these flanges.

Install the hanging isolators (located in the return-air section of the unit) into the six hanging brackets. 2. The base of the unit (hanging rails) must be fully supported while unit is being lifted for install. This can be achieved by using a lift with a large enough supporting surface, or a wooden structure can fully support the base if desired. 3. Secure the equipment to a joist, concrete, etc. with the use of 3/8 in. (9.7 mm) field provided (all-thread) rod. Each rod should contain field provided nuts and washers to complete the hanging installation. 4. All plumbing to the unit should conform per national and local codes and is the responsibility of the contractor. The 0.5 to 6 ton horizontals and EX/DXHG models do not need to be sloped. EXHG and DXHG 0.75 to 6 ton models must be installed level. 30 WSHP-SVX014J-EN Notes: · · Rods must be perpendicular to the mounting holes in the base rail of the horizontal unit. For 0.75 to 6 ton EXHF and DXHF models, follow pitching instructions from previous generation IOM. Figure 19. Hanging the unit Condensate Drain Connection Figure 20. Negative pressure system CLEAN OUT (CAPPED and SEALED) Install proper trapping to the equipment. The unit drain connection is 0.75 in. NPT for all DXH, DXV, and EXH/V 0.75 to 6 ton models. When designing the condensate trap for the water-source system, it is important to consider the unit draw-thru design requiring negative pressure trapping. In a properly trapped system, when condensate forms during normal operation, the water level in the trap rises until there is a constant flow. It is imperative to maintain water in the trap and not allow the trap to dry out during heating season. Keeping trap primed at all times will enable the water to flow properly. See the figure above for appropriate dimensions required in a negative pressure system. WSHP-SVX014J-EN Installation Supply Pipe Connections Figure 21. Supply/return pipe connections WATER-OUT WATER-IN AUTOMATIC BALANCING HOSE KIT RETURN TO LOOP SUPPLY FROM CENTRAL PUMP Connect the supply and return hoses to the water-inlet (from supply) and water-outlet (to return) of the unit. For vibration isolation, it is recommended that flexible steel braided hoses be installed instead of hard piping the equipment to the main loop system. Figure above shows connection of a Hays Mesurflo® balancing hose kit to the water-in and water-out of a vertical unit. Note: Above figure example incorporates the Hays Mesurflo® balancing hose kit and a 2-position isolation valve into the system design. An isolation valve is often used in variable speed pumping applications. The isolation valve is designed to stop water flow to the unit during non operation times. This allows the loop water pumps to run only when a requirement for pumping is needed for greater energy efficiency of the overall system design. Cleaning and Flushing the Water Loop After the piping system is complete, the flexible hose connectors should be doubled back to complete the water circuit external to the unit (avoiding trash settle-out in the condenser). An extra pipe may be necessary to connect the hose kits. 1. Water circulation system should be filled with clean water using the water make up connections. Note: Air vents should be open during filling. 2. With the air vents closed, start the circulating pump and then crack the air vents to bleed off the trapped air, assuring circulation through all components of the system. Note: Make up water must be available to the system to replace the volume formerly occupied by the air that is bled off. 3. With the air vented and the water circulating, the entire system should be checked for leaks with repairs made as required. 4. Operate the supplementary heat system (boiler) making checks per manufacturer's instructions. During this operation, visual checks should be made for leaks 31 Installation that may have occurred due to increased heat. Repair as required. 5. Open the system at the lowest point for the initial blow down (making sure the make up water is equal to the water being dumped). Continue blow down until the water leaving the drain runs clear, but not less than 2 hours. 6. Shut down pumps and supplementary heat system. Reconnect the hoses placing the water-to-refrigerant heat exchanger in the water circulating system. Note: Vents should be open when the pumps and supplementary heat system are shut down.

This can be done with the dry contacts of a relay. When that connection is opened, it terminates the power voltage to the controller, which stops/prevents all control function including the fan and compressor. Airflow Adjustment WARNING Rotating Components! Failure to disconnect power before servicing could result in rotating components cutting and slashing technician which could result in death or serious injury. During installation, testing, servicing and troubleshooting of this product it may be necessary to work with live and exposed rotating components. Have a qualified or licensed service individual who has been properly trained in handling exposed rotating components, perform these tasks. Units with Deluxe 24V controls The ECM is programmed for constant torque and delivers airflow similar to a PSC motor while operating at a higher efficiency. Figure 33. ECM control box Installation Figure 34. ECM control board 1. Potentiometer will be used to adjust the PWM output 2. Seven segment display Using a screwdriver, the potentiometer will be used to adjust the PWM output from 20% to 100% PWM. Increasing the PWM will increase the motor speed. When setting the airflow for air balancing, the high-speed terminal (GH) must have 24 Vac signal. This will ensure that the PWM output will be adjusted for the full load airflow. The display will show the commanded motor speed percentage. If running on low speed (GL), the low-speed value will be displayed. If running in GH the high-speed value will be displayed. If both GH and GL input signals are present, the PWM output value will be the GH value. Note: ECM control board is only on units with Deluxe 24V controls. Tracer® TU is used to adjust fan speed on units with SymbioTM 400-B/UC400-B controls. WSHP-SVX014J-EN 39 Installation Waterside Economizer Installation WARNING Hazardous Voltage! Failure to disconnect power before servicing could result in death or serious injury. Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/ tagout procedures to ensure the power can not be inadvertently energized. Verify that no power is present with a voltmeter. WARNING Proper Field Wiring and Grounding Required! Failure to follow code could result in death or serious injury. All field wiring MUST be performed by qualified personnel. Improperly installed and grounded field wiring poses FIRE and ELECTROCUTION hazards. To avoid these hazards, you MUST follow requirements for field wiring installation and grounding as described in NEC and your local/state/national electrical codes. Waterside Economizer Installation for Horizontal 0.75 to 6 Ton Units The following steps were sequenced to aid in the installation and pairing of a water side economizer to a 0.75 to 6 ton horizontal water source heat pump. 1. Remove the filter bracket from the unit. It is secured by four screws: three on top (circled) and two on the bottom (not shown). Do not discard the filter brackets. Figure 35. Step 1 fasteners (total of four for each bracket). The engagement hole locations and L-Bracket can be seen in the Figure 36, p. 40 . Figure 36. Step 2 3. Attach the filter bracket to the waterside economizer using the five screws removed earlier. Install the air filter. 4. Install the braided hose connecting point A (leaving the WSE) to point B (entering the WSHP). Connect the supply water to point D and the return water to point C. Figure 37. Step 4 2. Mount the waterside economizer to the unit. It is secured to the unit using the three engagement holes used for the filter bracket on the top. Secure the sides of the economizer using the two L-Brackets on each side by lining up the engagement holes for the 40 5. Locate the entering water sensor that is located behind the unit's control box, and wire tie it to the water SUPPLY side of the piping. The sensor must be mounted before the two-position valve. Attaching the sensor anywhere else will cause the WSE to not operate correctly. Bundle up any excess sensor wire and wire tie the bundle neatly. 6. Locate the WSE valve wires (35B (COM), 36B (OPEN), 37B (CLOSE)) behind control box, and connect to the valve actuator. Bundle up any excess wire and wire tie the bundle neatly. Direction of rotation is reversible with switch. 7. Insulate the economizing piping package and the associated hoses via field pipe insulation. Insulating the WSHP-SVX014J-EN piping will prevent condensation from forming on the pipe and dripping on the floor. Notes: · Trane does not provide insulation on the economizing piping package. The insulation must be field provided and field installed. · Trane does not provide condensate overflow protection of the waterside economizer. This must be field provided and installed. 8. Field pipe the drain lines of the waterside economizer and water-source heat pump. Both the WSE and unit condensate drains must be separately trapped for proper handling of condensation (see Figure 38, p. 41 ). Both Vertical and Horizontal units will be piped similar to each other. The drain connection is located on the bottom side of the economizing coil. Figure 38.

Set the thermostat to the highest position. 2. Set the thermostat system switch to COOL with the fan control to AUTO. The compressor should NOT run. 3. Reduce the thermostat setting until the compressor, reversing valve, solenoid valve, and loop pump are energized. Adjust water flow utilizing pressure/ temperature plugs and comparing to tables contained in specification sheet data. Water leaving the heat exchanger should be warmer than the entering water temperature (approximately 9 to 12ºF); blower operation should be smooth; compressor and blower amps should be within data plate ratings; the suction line should be cool with no frost observed in the refrigerant circuit. 4. Check the cooling refrigerant pressures against values in "Operating Pressures," p. 52. Note: If cooling mode is activated, and the entering water temperature of the heat pump falls below 55ºF, the 2-position, water side economizing valve will become energized (open) and compressor operation will halt allowing for free cooling in the space. 5. Turn the thermostat system switch to the OFF position. Unit should stop running and the reversing valve should de-energize. 6. Leave unit off for approximately FIVE minutes to allow for pressure equalization. 7. Turn the thermostat to the lowest setting. 8. Set the thermostat system switch to the HEAT position. 9. Adjust the temperature setting upward until the unit is energized. Warm air should blow from the register. A water temperature decrease of approximately 5 to 9°F leaving the heat exchanger should be noted. The blower and compressor operation should be smooth with no frost observed in the refrigeration circuit. 10. Check the heating refrigerant pressures against values in "Operating Pressures," p. 52. Note: For units with boilerless electric heat option: In heating mode, if the entering water temperature of the heat pump falls below 45ºF, the electric heater will be energized, and compressor operation will halt. Once the entering water temperature rises above 50ºF, the boilerless controls returns the unit. 11. Set the thermostat to maintain the desired space temperature. 12. Instruct the owner on system operation. Table 29. Waterside economizing three-way valve specifications (DXHG/DXVG units) Unit Size Valve Conn. Size Valve Pres.

(A recommendation of all system flushing of debris from the water-to-refrigerant heat exchanger, along with air purging from the water-to-refrigerant heat exchanger be done in accordance with the Closed-Loop/Ground Source Heat Pump Systems Installation Guide). · Is vibration isolation provided? (i.e. unit isolation pad, hose kits) · Is unit serviceable? (See clearance specifications in Unit Dimensions and Weights). · Are the low/high-side pressure temperature caps secure and in place? · Are all the unit access panels secure and in place? · Is the thermostat in the OFF position? · Is the water flow established and circulating through all the units? · Is the duct work correctly sized, run, taped, insulated and weather proofed with proper unit arrangement? · Is the condensate line properly sized, run, trapped, pitched and primed? · Is the zone sensor correctly wired and in a good location? · Does the indoor blower turn freely without rubbing? · Has all work been done in accordance with applicable local and national codes? · Has heat transfer fluid been added in the proper mix to prevent freezing in closed system application? WSHP-SVX014J-EN 51 Start-Up Initial Unit Start-Up Note: Start-up with the heat pump thermostat is included below: 1. Set the thermostat to the highest position. 2. Set the thermostat system switch to COOL with the fan control to AUTO. The compressor should NOT run. 3. Reduce the thermostat setting until the compressor, reversing valve, solenoid valve, and loop pump are energized. Adjust water flow utilizing pressure/ temperature plugs and comparing to tables contained in specification sheet data. 4. Water leaving the heat exchanger should be warmer than the entering water temperature (approximately 912ºF); blower operation should be smooth; compressor and blower amps should be within data plate ratings; the suction line should be cool with no frost observed in the refrigerant circuit. 5. Check the cooling refrigerant pressures against values in "Operating Pressures," p. 52. 6. Turn the thermostat system switch to the OFF position. Unit should stop running and the reversing valve should de-energize. 7. Leave unit off for approximately FIVE minutes to allow for pressure equalization. 8. Turn the thermostat to the lowest setting. 9. Set the thermostat system switch to the HEAT position. 10. Adjust the temperature setting upward until the unit is energized. Warm air should blow from the register. A water temperature decrease of approximately 5-9ºF leaving the heat exchanger should be noted. The blower and compressor operation should be smooth with no frost observed in the refrigeration circuit. 11. Check the heating refrigerant pressures against values in "Operating Pressures," p. 52. 12. Set the thermostat to maintain the desired space temperature. 13. Instruct the owner on system operation.

Failure to follow all precautions in this manual and on the tags, stickers, and labels could result in death or serious injury. Technicians, in order to protect themselves from potential electrical, mechanical, and chemical hazards, MUST follow precautions in this manual and on the tags, stickers, and labels, as well as the following instructions: Unless specified otherwise, disconnect all electrical power including remote disconnect and discharge all energy storing devices such as capacitors before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized. When necessary to work with live electrical components, have a qualified licensed electrician or other individual who has been trained in handling live electrical components perform these tasks. Preventative Maintenance Maintenance on the unit is simplified with the following preventive suggestions: Filter maintenance must be performed to assure proper operation of the equipment. Filters should be inspected at least every three months, and replaced when it is evident they are dirty. Filter sizing is shown below. Table 44.

It is good practice to check the tightness of the various wiring connections within the control panel. A strainer (60 mesh or greater) must be used on an open loop system to keep debris from entering the unit heat exchanger and to ensure a clean system. For units on well water, it is important to check the cleanliness of the water-to-refrigerant heat exchanger. Should it become contaminated with dirt and scaling as a result of bad water, the heat exchanger will have to be back flushed and cleaned with a chemical that will remove the scale. This service should be performed by an experienced service person. WSHP-SVX014J-EN 61 Maintenance WARNING Hazardous Chemicals! Failure to follow this safety precaution could result in death or serious injury. Coil cleaning agents can be either acidic or highly alkaline and can burn severely if contact with skin or eyes occurs. Handle chemical carefully and avoid contact with skin. ALWAYS wear Personal Protective Equipment (PPE) including goggles or face shield, chemical resistant gloves, boots, apron or suit as required. For personal safety refer to the cleaning agent manufacturer's Materials Safety Data Sheet and follow all recommended safe handling practices. It should be noted that the water quality should be checked periodically (See below). Table 46. Water quality Scaling Calcium and magnesium (total hardness) Amount Less than 350 ppm Corrosion pH Hydrogen Sulfide 7-9.5 Less than 1 ppm Table 46. Water quality (continued) Scaling Sulfates Chlorides Carbon Dioxide Total dissolved solids (TDS) Amount Less than 25 ppm Less than 125 ppm Less than 75 ppm Less than 1000 ppm Biological Growth Iron Bacteria Low Erosion Suspended Solids Low Condensate Trap For units incorporating a negative trap design, ensure that the condensate system is primed with water at all times. Allowing a negative, pressure condensate system to run dry could cause a break in the condensate seal allowing the fan to draw water from the condensate line to spray moisture into the mechanical system. By maintaining a primed condensate trap, a seal will be created and will help prevent these complications. 62 WSHP-SVX014J-EN Troubleshooting WARNING Hazardous Service Procedures!
