DANGER
Disconnect all electrical power before servicing unit to prevent
injury or death due to electrical shock.
CAUTION
Personal injury hazard. Wear protective gloves to avoid possible
cuts and abrasions from exposed edges. Avoid contact with
sharp edges.

Procedure

If the unit has a cooling coil, check the condensate drain pan to be sure
it slopes down toward the drain stub-up end. To do so, compare the
right and left hand drain pan ends to Figures 30 & 31. The end with
the shallow lower bracket (Figure 30) is the low end of the drain pan.
To reverse the slope of the drain pan do the following:
1. Remove the lower bracket and upper plate from each end of the
unit, as shown in figures 30 and 31. This is done by removing the
screws in each with a 1/4 inch nut driver.
2. Reinstall the brackets on the opposite end of the unit.
NOTICE
The drain pan has two (2) connections on each end; a standard
drain connection and an overflow connection.
3. Verify the standard drain connection is open on the low (drain)
end only. If the drain connection stub-outs at the high end of the
drain pan are open, seal them water tight with silicone sealer or
similar.
4. Mount static equalizer cover to low end bracket of drain pan.

To Clean the Drain Pan
1. Remove the shallow and deep upper plates from the unit (see figures
29 and 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.
