OPERATING THE UNIT
Condensate Removal
There are several ways to remove collected condensate.
1 By emptying the bucket each time it’s full.
2. By continuously draining through a hose into a drain.
3. By pumping water out of the bucket through a hose into a drain
(pump only models).
NOTES:
• When you remove the bucket, do not touch any parts inside of the unit.
Doing so may damage the product or cause injury.
• Be sure to push the bucket gently all the way back into the unit.
• If the pump suction line drops down when you remove the bucket(See Fig.
6), you must push the pump’s suction line back up toward the top of the
cavity where the bucket resides before replacing the bucket (See Fig. 7).
• When the continuous drain feature is not being used, remove the drain hose
from the outlet and reinstall the plug.
• When the pump feature is not being used, remove the pump drain hose.

(0od=1/4”) to the pump drain outlet on the rear of the unit.
• Before activating the condensate pump, ensure that the garden hose,
continuous drain hose and Adapter A subassembly are removed from
the unit. Be certain that the continuous drainage outlet is plugged
securely. (See Fig. 14).
• Next insert the factory supplied pump condensate hose into the pump
discharge outlet. Ensure that the connection is secure to prevent water
leaks by slightly tugging on the hose gently. (See Fig. 15).
• or other suitable drainage location, ensuring that there are no kinks in
the hose to obstruct condensate drainage. Ensure that the end of the
hose is level or directed downward into the drain for proper drainage.
• Press the button labeled pump on the control panel, then select the
desired relative humidity level and fan speed to activate the pump.
When the bucket is full, the pump will begin to operate . NOTE: The
This is a normal phenomenon.
ATTENTION: If the pump operation light blinks when the pump is
operational, this means there is a problem with the pump feature that
requires trouble shooting. CHECK THE FOLLOWING:
• Ensure the pump’s strainer is not clogged. To check the strainer and/or
unclog it. Remove the bucket. Simply pull down the condensate pump’s
inlet hose. The strainer is a small screened cup, which can easily twist
off to be cleaned. Remove only debris from the screen of the strainer
and twist it back on the pump inlet hose. Push the pump inlet hose
back into the proper position and re-install the bucket. (See Fig. 16).
• Check that the pump’s drain hose is not kinked or has anything
blocking the condensate from draining.
• Turn on the unit. Ensure the bucket is empty, then re-install it. Be
certain it is properly seated.
•Turn off the unit, then turn on again. If the error repeats, call for service.
CAUTION:
•Do not use the pump feature when the outdoor temperature is equal
to or less than 32°F (0°C), otherwise condensate may freeze inside
the pump’s drain line, blocking condensate removal and possibility
damaging the pump. Make sure to empty the bucket once a week when
using the pump drainage feature.
•When the pump drainage feature is not being used, remove the
pump drain hose from the outlet by pushing the pump’s drain outlet
connection toward the cabinet while pulling the pump drain hose
outward, away from the cabinet. (See Fig. 17).

1. Clean the Grille and Cabinet
• Use water and a mild detergent. Do not use bleach or abrasives.
• Do not splash water directly into the unit. Doing so may cause an
electrical shock, cause the insulation to deteriorate, or cause the unit
to rust.
• The air intake and outlet grilles may become clogged with dust, so
use a vacuum attachment with brush to clean.
.
2. Clean the Bucket
• Every few weeks, clean the bucket to prevent growth of mold, mildew
mild detergent. Swish it around in the bucket, empty and rinse.
After cleaning, the bucket must be reinstalled and securely seated for

frequently if needed.
•
•
•
CAUTION:
the dirt and lint will clog the coils and reduce performance.
4. Clean the Pump Strainer (for models with pumps only)
• Remove the bucket.
• Simply pull down the pump inlet hose inside the empty cavity where
the bucket resides (See Fig. 19).
• The strainer is a small screened cap, which can easily twist off for
cleaning.
• Remove any debris from the screen of the strainer and twist back on
to the pump inlet hose.
• Push the inlet hose back into it’s proper position, then reinstall the
bucket.
5. When not using the unit for long time periods
• After turning off the unit, wait one day before emptying the bucket to
be sure all condensate on the coils has drained.
•
• Unplug the power cord and bundle it using the cable tie (Fig. 20).
• Store the unit upright in a dry, wall-ventilated place until ready to use
