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. WARN- ING 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.

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 hori- zontally 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 responsi- bility of the installing contractor to determine and comply with ALL applicable codes and regulations.

INSTALLATION

Step 1 — Check Jobsite — Installation, operation and 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

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 installa- tions. 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.

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 car- ton 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.

NOTE: It is the responsibility of the purchaser to file all necessary claims with the shipping company.

1.Verify unit is correct model for entering water tempera- ture of job.

2.Be sure that the location chosen for unit installation pro- vides 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 appropri- ate 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.
