For 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 impede water flow. Place the end of the hose into the drain and make sure the end of the hose is directed downward to let the water flow smoothly. (See Figs with 
).
Installation not recommended. (See Figs with X ). 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 predetermined level, the unit beeps 8 times. The digital display shows “P1.” At this time the air conditioning/dehumidifi cation process will immediately stop. However, the fan motor will continue to operate (this is normal). Carefully move the unit to a drain location, 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.
INSTALLATION INSTRUCTIONS
Choosing the Right Location
Your installation location should meet the following requirements:
- Make sure that you install your unit on an even surface to minimize noise and vibration.
- The unit must be installed near a grounded plug, and the Collection Tray Drain (found on the back of the unit) must be accessible.
- The unit should be located at least 30 cm (12”) from the nearest wall to ensure proper air conditioning.
