Recommended Ground Method

For personal safety, this air conditioner must be grounded. This air conditioner is equipped with a 3 prong power supply cord with a grounded plug. To minimize the possibility of electrical shock, the cord must be plugged into a 3 prong outlet and grounded in accordance with all local codes and ordinances. If a 3 prong outlet is not available, it is the customer's responsibility to have a properly grounded 3 prong outlet installed by a qualified electrician.

It is the customer's responsibility:

• To contact a qualified electrician.
• To assure that the electrical installation is adequate and in conformance with the National Electrical Code, ANSI/NFPA 70-latest edition, and all local codes and ordinances.

LCDI Power Cord and Plug

This air conditioner is equipped with an LCDI (Leakage Current Detection and Interruption) power cord that is required by UL. This power supply cord contains state-of-the-art electronics that sense leakage current. If the cord is damaged and leakage occurs, power will be disconnected from the unit.

The test and reset buttons on the LCDI Plug are used to check if the plug is functioning properly.

To test the plug:

• Plug power cord into a grounded 3 prong outlet.
• Press RESET (on some units a green light will turn on).
• Press the TEST Button, the circuit should trip and cut all power to the air conditioner (on some units a green light may turn off).

Care and Cleaning

Clean your air conditioner to keep it looking new and to minimize dust build up.

Air Filter Cleaning

The air filter should be checked at least once every month to see if it needs cleaning. Trapped particles and dust can build up in the filter and may decrease airflow as well as cause the cooling coils to accumulate frost.

To clean the air filter:

• Remove the filter by sliding it out from the front right side of the air conditioner. (See diagram 14).
• Wash the filter using liquid dish soap and warm water. Rinse the filter thoroughly. Gently shake the filter to remove excess water.
• Let the filter dry completely before placing it into the air conditioner.
• If you do not wish to wash the filter, you may vacuum the filter to remove the dust and other particles.

Diagram 14 description: An illustration showing the air filter being slid out from the front right side of the air conditioner unit. The filter has a handle for easy removal.

Wear and Tear

To minimize wear and tear on the air conditioner, always wait at least 3 minutes before changing modes. This will help prevent the compressor from overheating and the circuit breaker from tripping.

Cabinet Cleaning

To clean the air conditioner cabinet:

• Unplug the air conditioner to prevent shock or a fire hazard. The cabinet and front panel of the air conditioner may be dusted with an oil-free cloth or washed with a cloth dampened in a solution of warm water and mild liquid soap. Rinse thoroughly with a damp cloth 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.

Winter Storage

To store the air conditioner when it is not in use for an extended period of time, remove it carefully from the window according to the installation instructions and cover it with plastic or place it in the original box.
