Mu LO
Your Room Air Conditioner unit is designed to be highly efficient and save energy.
Follow these recommendations for greater efficiency
1 Select thermostat setting that suits your
comfort needs and leave the thermostat at
that chosen setting
2. The filter is very efficient in removing airborne
particles Keep air filter clean Normally, filter
should be cleaned once a month More
frequent cleaning may be necessary depending
on outdoor and indoor air quality
3 Use drapes, curtains, or shades to keep
direct sunlight from heating your room but
DO NOT obstruct the air conditioner Allow air to
circulate around the unit without obstructions
4 Start your air conditioner before outdoor
air becomes hot and uncomfortable This
avoids an initial period of discomfort while
the unit is cooling off the room
5 When outdoor temperature is cool
enough, use HIGH or LOW FAN
only (depending on your model) This
circulates indoor air, providing some
cooling comfort, and utilizes iess
electricity than when operating on a
cooling setting
Tools Needed for Window Installation
Screw drivers: Both Philips and flat head
Power drill: 1/8 inch diameter drill bit
Pencil
Measuring tape
Scissors
Carpenters level
Adjustable wrench

is obstructed and reduces efficiency The air filter
should be cleaned once a month More frequent
cleaning may be necessary depending on outdoor
and indoor air quality
Air Filter Removal:
