-During heating pump mode, remove the lower drain plug from
the back of the unit, install the drain connector(5/8" universal
female mender) with 3/4" hose(locally purchased).
For the models without drain connector, just attach the drain
hose to the hole. Place the open end of the Hose adaptor
directly over the drain area in your basement floor.
NOTE: Make sure the hose is secure so there are no leaks.
Direct the hose toward the drain, making sure that there are
no kinks that will stop the warter flowing.Place the end of the
hose into the drain and make sure the end of the hose is down
to let the water flow smoothly.(See Figs with . Do never let it
up.(See Figs with ).

When the continuous drain hose is not used, ensure that the
corresponding drain plug and knob are installed firmly to
prevent leakage.

-When the water level of the bottom tray reaches a predeter-
mined level, the unit beeps 8 times, the digital display area shows
"P1" . At this time the air conditioning/dehumidification process
will immediately stop. However, the fan motor will continue to
operate(this is normal). Carefully move the unit to a drain loca-
tion, remove the bottom drain plug and let the water drain away.
Reinstall the bottom drain plug and restart the machine until the
"P1" symbol disappears. If the error repeats, call for service.
NOTE: Be sure to reinstall the bottom drain plug firmly to prevent
leakage before using the unit.
