SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can be hazardous due to system pressure and electrical compo­nents. Only trained and qualified service personnel should install, repair, or service air-conditioning equipment.
Untrained personnel can perform basic maintenance func­tions of cleaning coils and filters and replacing filters. All other operations should be performed by trained service personnel. When working on air-conditioning equipment, observe precau­tions in the literature, tags and labels attached to the unit, and other safety precautions that may apply.
Improper installation, adjustment, alteration, service, mainte­nance, or use can cause explosion, fire, electrical shock or other conditions which may cause personal injury or property dam­age. Consult a qualified installer, service agency, or your distrib­utor or branch for information or assistance. The qualified in­staller or agency must use factory-authorized kits or accessories when modifying this product. Refer to the individual instruc­tions packaged with the kits or accessories when installing.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Catalog No. 04-53500007-01 Printed in U.S.A. Form 50R-5SI Pg 1 6-07 Replaces: 50R-4SI
Follow all safety codes. Wear safety glasses and work gloves. Use quenching cloth for brazing operations. Have fire extinguisher available. Read these instructions thoroughly and follow all warnings or cautions attached to the unit. Consult local building codes and the National Electrical Code (NEC) for special installation requirements.
Understand the signal words — DANGER, WARNING, and CAUTION. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARN­ING signifies hazards that could result in personal injury or death. CAUTION is used to identify unsafe practices, which would result in minor personal injury or product and property damage.
Recognize safety information. This is the safety-alert symbol ( ). When you see this symbol on the unit and in instructions or manuals, be alert to the potential for personal injury.
adequate space around the unit for servicing. See Fig. 1-3 for overall unit dimensions. Refer to Fig. 4 for an illustration of a typical horizontal installation.
VERTICAL AND DOWNFLOW UNITS (50RVC,RVR, RVS,RDS) — Vertical units are designed for indoor installa­tions. While vertical units are typically installed in a floor-level closet or a small mechanical room, the unit access guidelines for these units are very similar to those described for horizontal units. See Fig. 5-8 for overall dimensions. Refer to Fig. 9 for an example of a typical vertical installation. Refer to Fig. 10 for a sample downflow installation.
To avoid equipment damage, do not use these units as a source of heating or cooling during the construction process. The mechanical components and filters used in these units quickly become clogged with construction dirt and debris which may cause system damage.
Electrical shock can cause personal injury or death. Before installing or servicing system, always turn off main power to system. There may be more than one disconnect switch. Turn off accessory heater power if applicable.
GENERAL
This Installation and Start-Up Instructions literature is for Aquazone™ water source heat pump systems.
Water source heat pumps (WSHPs) are single-package hori­zontally and vertically mounted units with electronic controls designed for year-round cooling and heating. Aquazone WSHPs are available in the following unit configurations:
• RHC standard efficiency with horizontal airflow and
right, left or back discharge
• RHR high efficiency with horizontal airflow and right,
left or back discharge
• RHS premium efficiency with horizontal airflow and
right, left or back discharge
• RVC standard efficiency with vertical airflow and top
discharge
• RVR high efficiency with vertical airflow and top
discharge
• RVS premium efficiency with vertical airflow and top
discharge
• RDS premium efficiency with vertical airflow and bot-
tom discharge (downflow)
IMPORTANT: The installation of water source heat pump units and all associated components, parts, and accessories which make up the installation shall be in accordance with the regulations of ALL authorities having jurisdiction and MUST conform to all applicable codes. It is the responsi­bility of the installing contractor to determine and comply with ALL applicable codes and regulations.
INSTALLATION
Step 1 — Check Jobsite —
maintenance instructions are provided with each unit. Before unit start-up, read all manuals and become familiar with the unit and its operation. Thoroughly check out the system before operation. Complete the inspections and instructions listed below to prepare a unit for installation. See Tables 1-3 for unit physical data.
HORIZONTAL UNITS (50RHC,RHR,RHS) — Horizontal units are designed for indoor installation only. Be sure to allow
Installation, operation and
Step 2 — Check Unit — Upon receipt of shipment at
the jobsite, carefully check the shipment against the bill of lading. Make sure all units have been received. Inspect the car­ton or crating of each unit, and inspect each unit for damage. Ensure the shipping company makes proper notation of any shortages or damage on all copies of the freight bill. Concealed damage not discovered during unloading must be reported to the shipping company within 15 days of receipt of shipment.
1. Verify unit is correct model for entering water tempera­ture of job.
2. Be sure that the location chosen for unit installation pro­vides ambient temperatures maintained above freezing. Well water applications are especially susceptible to freezing.
3. Be sure the installation location is isolated from sleeping areas, private offices and other acoustically sensitive spaces.
NOTE: A sound control accessory package may be used to help eliminate sound in sensitive spaces.
4. Check local codes to be sure a secondary drain pan is not required under the unit.
5. Be sure unit is mounted at a height sufficient to provide an adequate slope of the condensate lines. If an appropri­ate slope cannot be achieved, a field-supplied condensate pump may be required.
6. Provide sufficient space for duct connection.
7. Provide adequate clearance for filter replacement and drain pan cleaning. Do not allow piping, conduit, etc. to block filter access.
8. Provide sufficient access to allow maintenance and servicing of the fan and fan motor, compressor and coils. Removal of the entire unit from the closet should not be necessary.
9. Provide an unobstructed path to the unit within the closet or mechanical room. Space should be sufficient to allow removal of unit if necessary.
10. Provide ready access to water valves and fittings, and screwdriver access to unit side panels, discharge collar, and all electrical connections.
11. Where access to side panels is limited, pre-removal of the control box side mounting screws may be necessary for future servicing.

STORAGE — If the equipment is not needed immediately at the jobsite, it should be left in its shipping carton and stored in a clean, dry area of the building or in a warehouse. Units must be stored in an upright position at all times. If carton stacking is necessary, stack units a maximum of 3 high. Do not remove any equipment from its shipping package until it is needed for installation.
PROTECTION — Once the units are properly positioned on the jobsite, cover them with either a shipping carton, vinyl film, or an equivalent protective covering. Cap open ends of pipes stored on the jobsite. This precaution is especially important in areas where painting, plastering, or spraying of fireproof mate­rial, etc. is not yet complete. Foreign material that accumulates within the units can prevent proper start-up and necessitate costly clean-up operations.
Before installing any of the system components, be sure to examine each pipe, fitting, and valve, and remove any dirt or foreign material found in or on these components.
DO NOT store or install units in corrosive environments or in locations subject to temperature or humidity extremes (e.g., attics, garages, rooftops, etc.). Corrosive conditions and high temperature or humidity can significantly reduce performance, reliability, and service life. Always move units in an upright position. Tilting units on their sides may cause equipment damage.
INSPECT UNIT — To prepare the unit for installation, com­plete the procedures listed below:
1. Compare the electrical data on the unit nameplate with ordering and shipping information to verify that the correct unit has been shipped.
2. Verify that the unit is the correct model for the entering water temperature of the job.
3. Do not remove the packaging until the unit is ready for installation.
4. Verify that the refrigerant tubing is free of kinks or dents, and that it does not touch other unit components.
5. Inspect all electrical connections. Be sure connections are clean and tight at the terminals.
6. Loosen compressor bolts until the compressor rides freely on springs. Remove shipping restraints.
7. Remove the four
1
/4 in. shipping bolts from compressor support plate (two bolts on each side) to maximize vibra­tion and sound alternation.
Failure to remove shipping brackets from spring-mounted compressors will cause excessive noise and could cause component failure due to added vibration.
8. Remove any blower support cardboard from inlet of the blower.
9. Locate and verify any accessory kit located in compressor section.
10. Remove any access panel screws that may be difficult to remove once unit is installed.

conversion process is the same for right and left return configu­rations. See Fig. 11 and 12.
NOTE: It is not possible to convert return air between left or right return models in the field due to refrigerant piping changes.
Preparation
— The unit should be on the ground in a well lit area for conversion. Hung units should be taken down to ground level before converting.
Side to Back Discharge Conversion
1. Remove screws to free the top and discharge panels. See Fig. 11.
2. Remove the access panel and set aside.
3. Lift the discharge panel from side of unit and rotate it to back using care not to damage blower wiring.
4. Check blower wire routing and connections for undo tension or contact with sheet metal edges. Re-route if necessary.
5. Check refrigerant tubing for contact with other compo­nents. Adjust if necessary.
6. Reinstall top panel using screws set aside in Step 1.
NOTE: Location for some screws at bottom of discharge panel may have to be changed.
7. Manually spin fan wheel to check for obstructions. Adjust for any obstruction found.
8. Replace access panel.
Back to Side Discharge Conversion
— Follow instructions above for Side to Back Discharge Conversion, noting the panels would be reversed.

Step 3 — Unit Location — The following guidelines
should be considered when choosing a location for a WSHP:
• Units are for indoor use only.
• Locate in areas where ambient temperatures are between 40 F and 100 F and relative humidity is no greater than 75%.
• Provide sufficient space for water, electrical and duct connections.
• Locate unit in an area that allows easy access and removal of filter and access panels.
• Allow enough space for service personnel to perform maintenance.
• Return air must be able to freely enter the space if unit needs to be installed in a confined area such as a closet.
NOTE: Correct placement of the horizontal unit can play an important part in minimizing sound problems. Since duct­work is normally applied to these units, the unit can be placed so that the principal sound emission is outside the oc­cupied space in sound-critical applications. A fire damper may be required by the local code if a fire wall is penetrated.
FIELD CONVERSION OF DISCHARGE AIR — The dis­charge air of the 50RHC,RHR,RHS horizontal units can be converted between side and back discharge in the field. The
