LG Central Air Conditioning Remote Condensing Unit Installation Instructions & Use And Care page 16

COOL - In this mode the house will be cooled if the desired temperature is below the actual inside temperature.
AUTO - In this mode the house will be heated or cooled when the inside temperature of the house falls outside a
specified range.
Thermostats also have a fan control. This controls the operation of the indoor fan that circulates the air inside the
house. The fan control has two modes:
AUTO - In this mode the fan will only operate when the house is being heated or cooled.
ON - In this mode the fan will run continuously regardless of whether the house is being heated or cooled.
ROUTINE MAINTENANCE
With routine maintenance, your new air conditioner will operate efficiently for many years. The following are main-
tenance items you can do to keep the unit running at peak efficiency:
OUTDOOR COIL
There are several things you can do to keep your outdoor coil clean and performing at top efficiency:
• Keep yard debris (grass clippings, dirt, leaves, etc.) from entering the condenser coil.
• Avoid planting bushes too close to unit.
• Use a condenser cap or cover during winter (Make sure to remove prior to cooling season). If using cover,
make sure cover is short enough to expose unit at least 4" from the ground)
• Verify that clothes dryer vent is not blowing lint at outdoor unit.
In some cases, the outdoor coil may need to be cleaned. This is a job that must be performed by a qualified
dealer.
AIR FILTER
The air filter collects dust and other particles to keep the air inside your house clean. In time, however, the filter
will begin to clog, restricting the airflow to the house and causing the indoor blower motor to work harder and less
efficiently. Replace disposable filters every six weeks.
Clean permanent filters by washing them with recommended detergent solution per the filter manufacturer's
instructions every six weeks.
To change the filter, you must do the following:
• Turn thermostat mode switch to "OFF"
• Turn thermostat fan switch to "AUTO"
• Warning! If filter is located inside the furnace or air handler, you must disconnect power to the
indoor and outdoor units. This may be done by switching the disconnect switches to "OFF" or
tripping your circuit breakers in the electrical panel. Failure to disconnect power may result in
