Make sure electrical service is adequate for the model you choose. This information can be found on the serial plate, which is located on the side of the cabinet and behind the grille.

  • Make sure the air conditioner is properly set. To minimize shock and fire hazards, proper grounding is important. The power cord is equipped with a three-dimensional grounding plug to protect against shock hazards.
  • Your air conditioner must be used correctly in the ground wall receptacle. If the reception of the wall you are using is not adequately grounded or protected, the time delay is secured by a fuse or circuit breaker, have a qualified electrician install the appropriate reception.

How to fix P1 error?

When the water level of the lower tray reaches a predetermined level, the unit beeps 8 times, the digital display area showing P1. At this time the air conditioning / dehumidification process will stop immediately. 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 remove the water drain (Fig.24). Restart the machine until the P1 symbol disappears. If the error repeats, call for service.

During dehumidifying mode, remove the drain plug from the back of the unit, install the drain connector (5/8 ”universal female connector) with 3/4” hose (purchased locally). For models without a drain connector, simply attach the drain hose to the hole. Place the open end of the tube directly on the drain area in your basement. Please refer to Fig.22 and 23.

Note: When operating or water drain always protects the carpet or floor from possible water leakage.

Cleaning: Wash the air filter by gently submerging it in warm water (about 40 ° C / 104 ° F) with a neutral detergent. Rub the filter and dry it in a shady place.

Mounting: Install the upper air filter after cleaning, then insert the side filter into the unit and install the lower filter using screws (see Fig.26).
