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

• Be sure the air conditioner is properly grounded. To minimize shock and fire hazards, proper grounding is important. The power cord is equipped with a three-prong grounding plug for protection against shock hazards.

• Your air conditioner must be used in a properly grounded wall receptacle. If the wall receptacle you intend to use is not adequately grounded or protected by a time delay fuse or circuit breaker, have a qualified electrician install the proper receptacle.

• Ensure the receptacle is accessible after the unit installation.

How to Fix Danby Ac Error Code P1?

When the water level of the bottom tray reaches a predetermined 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 location, remove the bottom drain plug and let the water drain away (Fig.24). Restart the machine until the P1 symbol disappears. If the error repeats, call for service.

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

NOTE: When operating or draining water always protect carpeting or floors from possible water spillage.
