Preventative Maintenance
As with all pumps, preventative maintenance is necessary to prevent issues from dirt and
slime that may accumulate in the drain system – including the drain pan, hose to the
condensate pump, pump reservoir, pump head and float assembly, and discharge tubing.
※ At least once per year, clean pump system
Basic-
1. Press the pump button (P) to drain water from reservoir.
2. Disconnect power to dehumidifier.
3. Mix a 16 oz solution of either 1 oz bleach to 15 oz water or 4 oz white vinegar to 12 oz
water.Pour into the drain tray at the base of the coils.
Note: If you get any cleaning solution on the coils, flush with water.
4. Allow to soak for 15 minutes.
5. Reconnect power to dehumidifier.
6. Fill reservoir and flush/cycle pump at least two times.
7. Repeat if needed or refer to Advanced instructions.
Advanced-
1. a. Use manual pump button “P”, to drain water from reservoir.
b. Unplug the dehumidifier and open cover to access pump.
c. Pump head can be removed from reservoir by pressing on tabs.
d. A wet-dry vacuum or towels can be used to remove remaining water from reservoir.
2. Fill pump reservoir with a diluted cleaning solution (15 oz water to 1 oz bleach or 12 oz
water to 4 oz white vinegar).
3. Reassemble pump and use manual pump button to flush mixture through discharge
tubing.
4.Pour same diluted mixture slowly into drain pan under evaporator coil and allow it to
clean hose from pan to pump. This process can be stopped when the pump energizes 1 time.
Note: If you get any bleach/water mixture on coils, flush with water.
