CAUTION
Do not use spray solvents or cleaners on or near the inlet side of the dehumidifier.
If desired, apply cleaner to a cloth and use to clean the cabinet.
MAINTENANCE
CLEAN OR REPLACE THE AIR FILTER
After initial installation, check the air filter after 6 months. If it appears
matted with dust, pet hair or other debris, maintain a 6-month
cleaning schedule. If it appears clean or lightly loaded, maintain a
12-month cleaning schedule. Replacement filters are Aprilaire Part
No. 4510 and can be purchased from your installing contractor.
Filter Cleaning Procedure
1. Turn the ON/OFF switch OFF.
2. Remove the filter access door from either side of the dehumidifier.
3. Slide the filter out of the dehumidifier.
4. Flush the filter with warm water and a mild detergent solution.
5. Shake off the excess water from the filter.
6. Replace the filter – make sure the filter seats in both the top and
bottom filter rails.
7. Replace the filter access door.
8. Turn the ON/OFF switch ON.
CHECK THE DRAIN
The drain should be checked annually to ensure there is no blockage
or air lock in the drain system. If the unit is not properly draining,
have it checked by a qualified service professional.
Procedure to Check Drain System
1. Turn the ON/OFF switch OFF.
2. Remove the filter access door from
either side of the dehumidifier.
3. Slide the filter out of the dehumidifier
to expose the evaporator coil.
4. Slowly pour a pint of water into
the dehumidifier drip pan near the
bottom of the evaporator coil so that
the water flows into the drain pan.
5. Check where the drain piping flows into the floor drain. If water
does not flow out, the unit is not properly draining.
6. Turn on the ON/OFF switch ON.
