Improper installation, adjustment, alteration, service, mainte-

nance, or use can cause explosion, fire, electrical shock or other

conditions which may cause personal injury or property dam-

age. Consult a qualified installer, service agency, or your distrib-

utor or branch for information or assistance. The qualified in-

staller or agency must use factory-authorized kits or accessories

when modifying this product. Refer to the individual instruc-

tions packaged with the kits or accessories when installing.

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.

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:
• PCH standard efficiency with horizontal airflow and

right, left or back discharge

• PCV standard efficiency with vertical airflow and top

discharge

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 (50PCH) —   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 illustration of a typical hori-

zontal installation.
VERTICAL UNITS (50PCV) — 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. 3 for overall di-

mensions. Refer to Fig. 4 for an example of a typical vertical

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 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,

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.

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.
