CARE AND MAINTENANCE
1) Be sure to unplug the unit before cleaning or servicing.
2) Do not use gasoline, thinner or other chemicals to clean
the unit.
3) Do not wash the unit directly under a tap or using a hose.
It may cause electrical danger.
4) If the power cord is damaged, it should be repaired by
an authorized repairman.
IMPORTANT:
1. Air filter
- Clean the air filter at least once every two weeks to prevent
inferior fan operation because of dust.
- Removal
This unit has two filters. Take the upper filter out along the
arrow direction as shown in Fig. 23. Remove the lower filter
by loosening the screw and taking out the filter as shown in
Fig. 23.
- Cleaning
Wash the air filter by immersing it gently in warm water
(about 104 O F/40 O C) with a mild detergent. Rinse the filter
and dry it in a cool, dry place.
- Mounting
Install the upper and lower air filters after cleaning as shown
in Fig. 24. Be sure to use the screw for the lower filter.
2. Unit enclosure
- Use a lint-free cloth soaked with mild detergent to clean
the unit enclosure. Finish by using a dry, clean cloth.
3. Unit idle for a long time
- Remove the rubber plug at the back of the unit and attach
a hose to drain outlet. Place the open end of the hose
directly over the drain area in your basement floor or over a
shallow pan (if no floor drain is available.) (See Fig. 21 & 22.)
- Remove the plug from the bottom drain outlet; all of the water
in the bottom tray will drain out (See Fig. 22.)
- Keep the appliance running on FAN mode for half a day in
a warm room to dry the appliance inside and prevent mold
from forming.
- Stop the appliance and unplug it. Wrap the cord and bundle
it with the band. Remove the batteries from the remote control.
- Clean the air filter and reinstall it.
- Disconnect the exhaust hose. Keep it safe and cover the
window (wall) hole with the adaptor cap or remove slider kit
from the window (wall) completely.
NOTE: The upper grille and upper air filter are connected and
can be separated. The same is true for the lower grille
and lower air filter.
