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 Ventilating 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.
Ideally, three sides of the unit should have a minimum access clearance of two feet but the unit can be
adequately serviced if two or only one side has a minimum two feet of clearance. The unit should be located
in the conditioned space to prevent freezing of the water lines.
Clearance to combustible materials is 0 inches for the heat pump. If an optional duct heater is installed, follow
the instructions packed with the duct heater for specifications regarding clearance to combustible material.
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.
DUCT WORK
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 air coil. This will
reduce possible objectionable compressor and air noise from entering the occupied space.
Design the duct work 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 duct work to the unit in order to keep the noise transmission to a
minimum.
