Energy Saving Guide
Read and follow the guide below to get the best performance and
efficiency from your window air conditioner:

Do not cover the air outlet (exhaust) while in use.

Use the timer to operate the unit before it is needed. For example, set
the timer to turn on the unit in cooling mode for three (3) or more
hours to cool the room before you arrive. You may want to operate the
unit all day if you live in a warmer climate.

Minimize the heat sources (direct sunlight, computers, servers,
people, etc.) in the room.

Close all windows and doors.

Use the unit in a contained room. For example, a room with four walls
and a ceiling, instead of a partitioned studio or warehouse.

Make sure the unit is secure with no gaps where air can escape.

Minimize the amount of humidity in the room. Run the unit as a
dehumidifier when necessary.

To prolong the compressor's life, please wait at least three (3)
minutes before turning the unit back on after shutting it off.

Inspect and keep the air filters clean by cleaning regularly.

Perform routine maintenance.
