Option 1
VPRG4 Return Air Grille
with Access Panel
A field-supplied (25" x 20")
filter is mounted inside the
hinged access door.
Kit contains hinge bracket
for mounting the door with
the return air openings high
or low on the door for optimal
sound attenuation. For 9,000 /
12,000 / 18,000 Btu models, it
is recommended to install the
door with the hinge on the right
side and the return air openings high
on the door. For 24,000 Btu models, it is recommended
to install the hinge on the left side with the return air
openings low on the door.
NOTICE
NOTICE
If Parts 1 & 2 fail for any reason, excess
condensate overflows from a spillway
directly into the wall plenum to the outside of the building.
IF THIS OCCURS, THIS IS A WARNING THAT THE
CHASSIS OR DRAIN NEEDS SERVICING.
There are two Indoor Return Air Grille options as shown in Figure 7.
Choose the option that best suits your needs. Use the installation
instructions provided with accessories for installation details.
