Unit Installation
Duct Connections
Minimum 24 gauge galvanized sheet
metal duct (supplied by the installer)
can be attached to duct collars
provided at the unit air outlet and
inlet, see Figures 6 for duct collar
dimensions. To attach, slip the duct
over the outlet collar and fasten the
duct and collar together with screws.
Field-supplied transition fittings
should be used in installations
where unit duct collars do not match
discharge air-grille collars.
Two approaches can be used to
attach an air supply chamber and
flexible ducts. One approach is to
remove the unit outlet collar, slip the
collar into flexible duct and then
attach the duct and collar by fastening
the screws on two vertical sides of
collar, as shown in Figure 5, Duct
Work - A.
The other approach is to slip the duct
over the unit outlet collar and then
fasten the duct and collar together
with screws or rivets, as shown in
Figure 5, Duct Work - B.
A return duct can be attached to the
return air collar provided at the unit. To
attach, slip the return duct over the
return air collar and fasten the duct
and collar together with screws.
Note: All ductwork should be properly
insulated to prevent condensation
installation site.
Electrical Connections
Check the unit nameplate for
electrical rating. Be sure wiring is
done according to local codes and
wiring diagrams and available power
supply must agree with electrical
