Proper use and care of your air conditioner will help ensure longer life of the unit. It is recommended to annually inspect and clean
the coils and condensate water passages. Expense of annual inspection is the consumer’s responsibility.
Insufficient Cooling
•Shut all windows and doors in room.
• Remove any obstructions from inside and outside louvers.
• Inspect filter and clean if dirty.
• Under certain conditions the cooling coils directly behind
the filter, may ice up and block the airflow. This is a common
occurrence in air conditioners caused when the outside tem-
perature drops below 70°F (21°C) while the humidity
remains high. If this happens, simply turn the unit off and
allow the ice to melt, then resume normal operation.
