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.
NOTICE
The drain pan has two (2) connections on each end; a standard
drain connection and an overflow connection.
Models ARQ, ERQ 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 32). 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 32. 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-outs 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 figures
32 and 33).
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 mullions,
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 surface 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, page 7)
