DUCT WORK

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.
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 

first 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 

filter grille, filters must be of sufficient 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 filter is standard 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 panel.  A 1-inch washable filter and 

2-inch pleated filter are also available as optional 

accessories.  The internal filter brackets are adjustable 

to accommodate the 2-inch filter by bending two (2) 

tabs down on each side of the filter 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, efficiency and cost of operation 

information is based upon the fresh air blank-off plate 

in place and is recommended for maximum energy 

efficiency.

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.
