APPLICATION AND LOCATION
GENERAL
Each unit is shipped internally wired, requiring both ground-
source and load-side water piping, aquastat wiring, 230/208
volt AC power wiring, and optional desuperheater piping.
The equipment covered in this manual is to be installed by
trained, experienced service and installation technicians.
These instructions and any instructions packaged with any
separate equipment required to make up the entire heat
pump system should be carefully read before beginning
the installation. Note particularly any tags and/or labels
attached to the equipment.
While these instructions are intended as a general
recommended guide, they do not in any way supercede any
national and/or local codes. Authorities having jurisdiction
should be consulted before the installation is made.
SHIPPING DAMAGE
Upon receipt of the equipment, the carton should be checked
for external signs of shipping damage. If damage is found,
the receiving party must contact the last carrier immediately,
preferably in writing, requesting inspection by the carrier’s
agent.
APPLICATION
Capacity of the unit for a proposed installation should be
based on heat loss calculations made in accordance with
methods of the Air Conditioning Contractors of America.
The piping systems should be installed in accordance all
local, state, and federal requirements, and to the references
included on Page 3 of this document.
LOCATION
The unit may be installed in a basement, closet, or utility
room provided adequate service access is ensured, and
equipment will not freeze.
These units are not approved for outdoor installation
and therefore must be installed inside structure being
conditioned.
Do not locate in areas subject to freezing in
the winter, or subject to sweating in the summer.
Prior to setting the unit, consider ease of piping and electrical
connections for the unit. Also for units which will be used
with a desuperheater, consider the proximity of the unit to
the water heater or storage tank. Place the unit on a solid
base, preferably concrete, to minimize undesirable noise and
vibration.
DO NOT
elevate the base pan on rubber or cork
vibration eliminator pads as this will permit the unit base to
act like a drum, transmitting objectionable noise.
UNIT STACKING
The GW-Series products are designed to allow them to
be stacked up to three units high to lower the amount of
installed square footage requirements. Included with unit
are tie plates to secure the units together once they are
stacked. Remove, then replace the bottom three (3) screws
from bottom sides of the upper unit, and the top of the
lower unit to apply the tie plate.
NOTE: The tie plates
are secured to the front of the control panel cover for
shipment.
ADDITIONAL CONSIDERATION
As an additional measure of safety in regard to the structure,
consider installing a drain pan with an alarm switch
underneath this water-bearing equipment.
REQUIRED STEPS AFTER FINAL
PLACEMENT
The compressor is secured to the unit base for shipping.
Although the unit will perform as designed with the
compressor secured in place, there may be noticeable
additional noise and vibration. To obtain the lowest noise
and vibration levels, remove the compressor shipping
brackets after the unit is in its final operating location.
To gain access to the compressor shipping brackets, remove
both the front and rear service panels. The brackets have
“hot pink” labels and are located on the compressor double
isolation base at the front and rear of the compressor. The
brackets are secured to the unit base with two (2) screws,
and secured to the isolation plate with a ¼" nut. Remove
and dispose of the two (2) screws and brackets. Reinstall
¼" nut once bracket is removed.
