Additional Things you should know

Now that you have mastered the operating procedure, here are more features in your control that you should become familiar with. The Cool circuit has an automatic 3 minute time delayed start if the unit is turned off and on quickly. This prevents overheating of the compressor and possible circuit breaker tripping. The fan will continue to run during this time. The control is capable of displaying temperature in degrees Fahrenheit or degrees Celsius. To convert from one to the other, press and hold the Left and Right Temp/Timer buttons at the same time, for 3 seconds.

Cleaning & maintenance

Air Filter & Cabinet Cleaning

The air filter should be checked at least once a month to see if cleaning is necessary. Trapped particles in the filter can build up and cause an accumulation of frost on the cooling coils.

• Take the filter by the center and pull up and out. Wash the filter using liquid dishwashing detergent and warm water. Rinse filter thoroughly.
• Gently shake excess water from the filter. Be sure the filter is thoroughly dry before replacing. Or, instead of washing you may vacuum the filter clean.

Note: Never use hot water over 40°C(104°F) to clean the air filter. Never attempt to operate the unit without the air filter. To prevent rust or electrical connections from being damaged, store air conditioner in an upright position and in a dry place.

• Be sure to unplug the air conditioner to prevent shock or fire hazard. The cabinet and front may be dusted with an oil-free cloth or washed with a cloth dampened in a solution of warm water and mild liquid dishwashing detergent. Rinse thoroughly and wipe dry.
• Never use harsh cleaners, wax or polish on the cabinet front.
• Be sure to wring excess water from the cloth before wiping around the controls. Excess water in or around the controls may cause damage to the air conditioner.
• Plug in air conditioner.
• Save Carton and these Installation
• Instructions for future reference. The carton is the best way to store unit during winter, or when not in use.
• When handling unit, be careful to avoid cuts from sharp metal edges and aluminum fins on front and rear coils.

CAUTION: Clean your air conditioner occasionally to keep it looking new. Be sure to unplug the unit before cleaning to prevent chock or fire hazards.

CAUTION: If you plan to store the air conditioner during the winter, remove it carefully from the window according to the installation instructions. Cover it with plastic or return it to the original carton.
