This Installation and Start-Up Instructions literature is for

Aquazone™ water source heat pump systems with Puron re-

frigerant.

Water source heat pumps (WSHPs) are single-package hori-

zontally and vertically mounted units with electronic controls

designed for year-round cooling and heating. 

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 Table 1 for unit

physical data.

Horizontal units are designed for indoor installation only.

Be sure to allow adequate space around the unit for servicing.

See Fig. 1 for overall unit dimensions. Refer to Fig. 2 for an ex-

ample of a typical horizontal installation.

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

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.

STORAGE — If the equipment is not needed for immediate

installation upon its arrival 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, they must be covered with either a shipping carton,

vinyl film, or an equivalent protective covering. Open ends of

pipes stored on the jobsite must be capped. This precaution is

Electrical shock can cause personal injury and death. Shut

off all power to this equipment during installation. There

may be more than one disconnect switch. Tag all discon-

nect locations to alert others not to restore power until work

is completed.

This system uses R-410A, which has higher pressures than

R-22 and other refrigerants. No other refrigerant may be

used in this system. Suction tubing design pressure is

3068 kPa and liquid tubing design pressure is 4522 kPa.

Failure to use gage set, hoses, and recovery systems

designed to handle R-410A refrigerant may result in per-

sonal injury and equipment damage. If unsure about equip-

ment, consult the equipment manufacturer.

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.

To avoid equipment damage, do not use these units as a

source of heating or cooling during the construction pro-

cess. The mechanical components and filters used in these

units quickly becomes clogged with construction dirt and

debris which may cause system damage.
