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 an d follow all warn-
ings 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 per-
sonal injury or product and property damage.
It is important to recognize safety information. This is the safety-
alert symbol ( ). When you see this symbol on the unit and in in-
structions or manuals, be alert to the potential for personal injury.
WARNING
Electrical shock can cause personal injury and death. Shut off
all power to this equipment during installation and service.
There may be more than one disconnect switch. Tag all
disconnect locations to alert others not to restore power until
work is completed.
CAUTION
DO NOT re-use compressor oil or any oil that has been ex-
posed to the atmosphere. Dispose of oil per local codes and
regulations. DO NOT leave refrigerant system open to air any
longer than the actual time required to service the equipment.
Seal circuits being serviced and charge with dry nitrogen to
prevent oil contamination when timely repairs cannot be com-
pleted. Failure to follow these procedures may result in dam-
age to equipment.
GENERAL
The Aquazone
™
50PSW water source heat pump (WSHP) is a
single-package vertically mounted unit with electronic controls
designed for year-round cooling and heating.
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
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 and 2 for unit physical data. Refer to Fig. 1-2 for
overall unit dimensions.
Units are designed for indoor installation only. Be sure to allow
adequate space around the unit for servicing. See Fig. 4 for service
clearances.
These units are not approved for outdoor installation and must be
installed indoors in the structure being conditioned. Do not locate
in areas where ambient conditions are not maintained within 40°F
to 100°F.
IMPORTANT: It is the installing contractors responsibility to
ensure that all equipment is installed with proper access for
services, start-up, installation of accessories, configuration of
control and other components, and equipment removal in
accordance with Carrier's recommended service clearances and
installation instructions. Please refer to the Carrier Commercial
WSHP Warranty Statement (document number 04-570008-01)
for details on warranty exclusions regarding equipment, access,
removal and clearances.
To avoid equipment damage, do not use these units as a source
of heating or cooling during the construction process. The
mechanical components used in these units can quickly
become clogged with construction dirt and debris which may
cause system damage.
Step 2 — Check Unit
INSPECTION
Upon receipt of shipment, 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
on both the interior and exterior. Ensure the shipping company
makes proper notation of any shortages or damage on all copies of
the freight bill. Concealed damage not discovered during unload-
ing must be reported to the shipping company within 5 days of re-
ceipt of shipment.
NOTE: It is the responsibility of the purchaser to file all necessary
claims with the shipping company.
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 between 50°F and 95°F. Units must be
stored in an upright position at all times. If carton stacking is nec-
essary, stack units a maximum of 3 cartons high. Do not remove
any equipment from its shipping package until it is needed for
installation.
INSPECT UNIT
To prepare the unit for installation, complete the procedures listed
below:
1.
Compare the electrical data on the unit nameplate with order-
ing 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.
