WARNING
!
UNIT OPERATION AND SAFETY HAZARD
Failure to follow this warning could result in personal injury
or equipment damage.
PuronR refrigerant systems operate at higher pressures than
standard R- -22 systems. Do not use R- -22 service equipment
or components on PuronR refrigerant equipment.
CAUTION
!
CUT HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care and
wear appropriate protective clothing and gloves when
handling parts.

INSTALLATION RECOMMENDATIONS

The GW Water- -to- -Water Heat Pump is Underwriters Laboratories
(UL) and (cUL) listed for safety. The water- -to- -water heat pumps
are designed to operate with entering fluid temperature between
25_F to 110_F.
Safety devices are built into each unit to provide the maximum
system protection possible when properly installed and maintained.
IMPORTANT: 50_ Min. EWT (entering water temperature) for
well water applications with sufficient water flow to prevent
freezing. Antifreeze solution is required for all closed loop
applications. Earth Coupled (Geothermal) applications should have
sufficient antifreeze solution to protect against extreme conditions
and equipment failure. Frozen water coils are not covered under
warranty.
IMPORTANT: This product should not be used for temporarily
heating or cooling during construction. Doing so may effect the
unit's warranty.
CAUTION
!
UNIT OPERATION HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
Discharge air configuration change is not possible on Heat
Pumps equipped with Electric Heat Option.
Check Equipment and Job Site
Moving and Storage
If the equipment is not needed for immediate installation upon its
arrival at the job site, it should be left in its shipping carton and
stored in a clean, dry area. Units must only be stored or moved in
the normal upright position as indicated by the "UP" arrows on
each carton at all times.
CAUTION
!
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage.
If unit stacking is required for storage, stack units as follows:
Do not stack units larger than 6 tons!
Vertical units: less than 6 tons, no more than two high.
Horizontals units: less than 6 tons, no more than three high.
Inspect Equipment
Be certain to inspect all cartons or crates on each unit as received at
the job site before signing the freight bill. Verify that all items have
been received and that there are no visible damages; note any
shortages or damages on all copies of the freight bill. In the event
of damage or shortage, remember that the purchaser is responsible
for filing the necessary claims with the carrier. Concealed damages
not discovered until after removing the units from the packaging
must be reported to the carrier within 24 hours of receipt.

Location / Clearance

Locate the unit in an indoor area that allows easy removal of the
filter and access panels, and has enough room for service personnel
to perform maintenance or repair. Provide sufficient room to make
fluid, electrical, and duct connection(s). If the unit is located in a
confined space such as a closet, provisions must be made for return
air to freely enter the space. On horizontal units, allow adequate
room below the unit for a condensate drain trap and do not locate
the unit above supply piping.
CAUTION
!
UNIT OPERATION HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
These units are not approved for outdoor installation;
therefore, they must be installed inside the structure being
conditioned. Do not locate in areas that are subject to
freezing.
CAUTION
!
UNIT DAMAGE AND/OR OPERATION HAZARD
Failure to follow this caution may result in equipment
damage and/or improper equipment operation.
It is extremely important to take the proper precautions to
insure that the heat pump unit is installed in the proper
location and that measures have been taken to prevent
rupturing the water coil due to freezing conditions.
Frozen water coils are not covered under the limited
product warranty.
