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.
