Desert Aire - SP Manual
Figure 8 - SP Standard Condenser Drain Location
An SP series dehumidifier ordered for roof curb mounting has its drain connection on the underside of
the unit to help prevent freezing, see Figure 9. Note that upon customer requests that this connection
may be installed on the side of the unit. When this is requested, additional precautions against freezing
and ice accumulation may be required when the outdoor air temperature drops below 32°F.
An optional outdoor air pre-filter may also be included in the rack. The rack can be removed in a similar
fashion for basic cleaning. Particulate such as cottonwood, airborne seeds, or dust can often be wiped or
vacuumed off of the surface of the filter.
If a more thorough cleaning is warranted, the pre-filter can be removed from the rack by removing the
1/4 – turn fasteners holding the screen to the rack. Use Dawn® liquid detergent and hose directed water
to clean the pre-filter if there is an accumulation of dirt or other contaminants.
2.3 Condensate Drain Piping
The condensate drain connection on the standard Desert Aire SelectAire Plus™ series dehumidifiers is a
1-1/2” PVC stub which penetrates the evaporator wall section on the access side of the unit, see Figure 8.
