NOTE: Vent options X, B and M are without exhaust capability. May require separate eld supplied barometric relief in building.
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/gain 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.

DUCT WORK
All duct work, supply and return, must be properly sized
for the design airow 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.
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.
A 1/4 inch clearance to combustible material for the rst
three feet of duct attached to the outlet air frame is required.
See Wall Mounting Instructions and Figures 3A, 3B and 4
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.
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 lter grille,
lters must be of sufcient size to allow a maximum
velocity of 400 fpm.
NOTE: If no return air duct is used, applicable installation
codes may limit this cabinet to installation only in a
single story structure.
FILTERS
A 1-inch throwaway lter is standard with each
unit. The lter slides into position making it easy to
service. This lter can be serviced from the outside by
removing the lter access panel. 2-inch pleated lters
are also available as optional accessories. The internal
lter brackets are adjustable to accommodate the 2-inch
lter by bending two (2) tabs down on each side of the
lter support bracket.
FRESH AIR INTAKE
All units are built with fresh air inlet slots punched in
the service door.
If the unit is equipped with a fresh air damper assembly,
the assembly is shipped already attached to the unit.
The damper blade is locked in the closed position.
To allow the damper to operate, the maximum and
minimum blade position stops must be installed. See
Figure 1.
All capacity, efciency and cost of operation
information is based upon the fresh air blank-off plate
in place and is recommended for maximum energy
efciency.
The blank-off plate is available upon request from the
factory and is installed in place of the fresh air damper
shipped with each unit.
CONDENSATE DRAIN
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.
