APPLICATION AND LOCATION
GENERAL
Units are shipped completely assembled and internally
wired, requiring only duct connections, thermostat
wiring, 230/208 volt AC power wiring, and water
piping. The equipment covered in this manual is to be
installed by trained, experienced service and installation
technicians. Any heat pump is more critical of proper
refrigerant charge and an adequate duct system than a
cooling only air conditioning unit.
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 supersede
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, formerly National Warm Air Heating and Air
Conditioning Association. The air duct system should
be sized and installed in accordance with Standards of
the National Fire Protection Association for the
Installation of Air Conditioning and Venting systems of
Other than Residence Type NFPA No. 90A, and
residence Type Warm Air Heating and Air Conditioning
Systems, NFPA No. 90B.
LOCATION
The unit may be installed in a basement, closet, or
utility room provided adequate service access is insured.
The unit is shipped from the factory as a right hand
return and requires
access clearance of two feet
minimum to the access panels on this side of the
unit.
If unit is to be field converted to left hand return
the opposite side will require access clearance of two
feet minimum.
Unit may be field converted to left hand return by
removing four (4) screws that secure the control panel
cover, removing two (2) screws that hold the control
panel in place, sliding the control panel through the
compressor compartment and re-securing the control
panel on the opposite side of the water coil. (See Figure
2.) The two (2) access doors from the right hand return
can be transferred to the left-hand return side and the
one (1) left hand panel can be transferred to the right
hand side.
Unit casing suitable for 0 inch clearance with 1-inch
duct clearance for at least the first 4 feet of duct. These
units are not approved for outdoor installation and
therefore must be installed inside the structure being
conditioned.
Do not locate in areas subject to freezing
in the winter or subject to sweating in the summer.
Before setting the unit, consider ease of piping, drain
and electrical connections for the unit. Also, for units
which will be used with a field installed heat recovery
unit, 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.
DUCTWORK
If the unit is to be installed in a closet or utility room
which does not have a floor drain, a secondary drain pan
under the entire unit is highly recommended.
DO NOT install the unit in such a way that a direct path
exists between any return grille and the unit. Rather,
insure that the air entering the return grille will make at
least one turn before entering the unit or coil. This will
reduce possible objectionable compressor and air noise
from entering the occupied space.
Design the ductwork according to methods given by the
Air Conditioning Contractors of America. When duct
runs through unconditioned spaces, it should be
insulated with vapor barrier. It is recommended that
flexible connections be used to connect the ductwork to
the unit in order to keep the noise transmission to a
minimum.
WARNING
Failure to provide the 1-inch clearance
between the supply duct and a combustible
surface for the first 3 feet of duct can result in
a fire.
