GENERAL
This Installation and Start-Up Instructions literature is for
Aquazone™ Water Source Heat Pump systems.
Water Source Heat Pumps (WSHP) are single-package hor-
izontally and vertically mounted units with electronic controls
designed for year-round cooling and heating.
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 Table 1 for unit
physical data.
Units are designed for indoor installation only. Be sure to al-
low adequate space around the unit for servicing. See Fig. 1A-
1C for overall unit dimensions.
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. Provide sufficient access to allow maintenance and
servicing of the compressor and coils.
5. Provide an unobstructed path to the unit within the closet
or mechanical room. Space should be sufficient to allow
removal of unit if necessary.
6. Provide ready access to water valves and fittings, and
screwdriver access to unit side panels.
7. 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 maxi-
mum of 3 high. Do not remove any equipment from its ship-
ping package until it is needed for installation.
