Reversing Condensate Drain End
CAUTION
Personal injury hazard. Wear protective gloves to avoid possible
cuts and abrasions from exposed edges. Avoid contact with sharp
edges.
Models ARQ and GRQ condensate drain connection is on the
left end (with static equalizer cover). If the job dictates that
the drain connection be made at the right end, perform the
following procedure to change the drain connection from left to
right end:
1. Remove the two screws holding the static equalizer cover
in place (Figure 29). It will be necessary to cut the seal
between the static equalizer cover and the drain pan.
2. Remove the upper plate and lower bracket from each
end of the unit, as shown in Figure 30. This is done by
removing the screws in each with a 1/4 inch nut driver.

3. Reinstall the brackets on the opposite end of the unit.
4. Reinstall the static equalizer cover into the right end drain
pan and secure to the upper plate. Use silicone sealer and
seal all gaps between the equalizer cover where it meets
the drain pan
5. Verify the drain connection is open on the low (drain) right
end only. The open drain connection stub-out at the high
end of the drain pan (left end), must be sealed water tight
with silicone sealer or similar.
To Clean the Drain Pan
1. Remove the shallow and deep upper plates from the unit
(see Figure 29
and Figure 30).
2. Spray water into the drain pan on the high end to wash
debris to the low end (drain end).
3. Remove any debris, making sure that the drain holes are
not obstructed.
4. Wipe the drain pan with a cloth.
5. Reinstall the upper plates.
Mounting Hole Locations & Dimensions
Move the unit ventilator into position against the wall surface.
Check to see that the unit ventilator is level from end to end and
back to front. Using a 4' level is recommended.

CAUTION
Leakage of outdoor air wastes energy, causes drafts and erratic
unit ventilator operation. Check the following details: At the correct
unit ventilator location, examine the wall surface. Make sure that it
is smooth, plumb, and perpendicular to the floor. The seals on the
rear of the unit ventilator will take up the small irregularities found
in normal masonry construction. If the wall is irregular or has mul-
lions, install furring strips to provide a flush surface against which
the unit ventilator can seal. If there are moldings on the floor/wall
line, omit them behind the unit ventilator. Provide a sealing sur-
face at the floor line. Install a seal pad under the unit to prevent
air leakage. Install the unit ventilator against a wall made of non-
combustible material, and on a floor made of non-combustible
material. Floor must be level, unbroken and structurally strong to
support the unit.
CAUTION
Unit must be anchored to an internal wall column or other suitable
support (see Figure 5 on page 8)
