1 Maximum size of the time delay fuse or HACR type circuit breaker for protection of field wiring conductors.
2 Based on 75°C copper wire. All wiring must conform to NEC and all local codes.
3 These “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National Electric Code
(latest revision), Article 310 for power conductor sizing.
CAUTION: When more than one field power conductor circuit is run through one conduit, the conductors must be derated. Pay special
attention to note 8 of table 310 regarding Ampacity Adjustment Factors when more than 3 conductors are in a raceway.

SHIPPING DAMAGE
Upon receipt of 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.
GENERAL
The equipment covered in this manual is to be installed
by trained, experienced service and installation
technicians.
The refrigerant system is completely assembled and
charged. All internal wiring is complete.
The unit is designed for use with or without duct work.
Flanges are provided for attaching the supply and return
ducts.
These instructions explain the recommended method to
install the air cooled self-contained unit and the
electrical wiring connections to the unit.
These instructions and any instructions packaged with
any separate equipment, required to make up the entire
air conditioning system should be carefully read before
beginning the installation. Note particularly “Starting
Procedure” and any tags and/or labels attached to the
equipment.
While these instructions are intended as a general
recommended guide, they do not supersede any national
and/or local codes in any way. Authorities having
jurisdiction should be consulted before the installation is
made. See Page 3 for information on codes and
standards.
Size of unit for a proposed installation should be based
on heat loss calculation made according to methods of
Air Conditioning Contractors of America (ACCA). The
air duct should be installed in accordance with the
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. Where local
regulations are at a variance with instructions, installer
should adhere to local codes.
Design the duct work according to methods given by the
Air Conditioning Contractors of America (ACCA).
When duct runs through unheated spaces, it should be
insulated with a minimum of one inch of insulation.
Use insulation with a vapor barrier on the outside of the
insulation. Flexible joints should be used to connect the
duct work to the equipment in order to keep the noise
transmission to a minimum.
These units are suitable for 0 inch clearance to
combustible material. See Wall Mounting Instructions
and Figures 3, 4, 5, 6 & 7 for further details.
Ducts through the walls must be insulated and all joints
taped or sealed to prevent air or moisture entering the
wall cavity.
Some installations may not require any return air duct.
A metallic return air grille is required with installations
not requiring a return air duct. The spacing between
louvers on the grille shall not be larger than 5/8 inch.
NOTE: If no return air duct is used, applicable
installation codes may limit this cabinet to
installation only in a single story structure.
Any grille that meets with 5/8 inch louver criteria may
be used. It is recommended that Bard Return Air Grille
Kit RG2 through RG5 or RFG2 through RFG5 be
installed when no return duct is used. Contact
distributor or factory for ordering information. If using
a return air filter grille, filters must be of sufficient size
to allow a maximum velocity of 400 fpm.
FILTERS
A 2-inch pleated filter is supplied with each unit. The
filter slides into position making it easy to service. This
filter can be serviced from the outside by removing the
filter access door.
CONDENSATE DRAIN – EVAPORATOR
A plastic drain hose extends from the drain pan at the
top of the unit down to the unit base. There are
openings in the unit base for the drain hose to pass
through. In the event the drain hose is connected to a
drain system of some type, it must be an open or vented
type system to assure proper drainage.
DUCT WORK
Any heat pump is more critical of proper operating
charge and an adequate duct system than a straight air
conditioning unit. All duct work, supply and return,
must be properly sized for the design airflow
requirement of the equipment. Air Conditioning
Contractors of America (ACCA) is an excellent guide to
proper sizing. All duct work or portions thereof not in
the conditioned space should be properly insulated in
order to both conserve energy and prevent condensation
or moisture damage.
