performance claims.
■ Do not use sharp instruments, rubbing alcohol, flammable
fluids, or abrasive cleaners to remove tape or glue. These
products can damage the surface of your air conditioner.
■ Handle the air conditioner gently.
Before Installing Air Conditioner
This air conditioner has been designed for installation through the
wall in a sleeve. It is the responsibility and obligation of the
customer to have this product installed by a qualified technician
familiar with through-the-wall installation.
OR
Install Air Conditioner in Existing Wall Sleeve
■ It is recommended that you remove the existing rear grille and
install the new grille that came with your air conditioner.
■ Handle air conditioner gently.
■ Be sure your air conditioner does not fall out of the opening
during installation or removal.
■ The place where the power cord exits the air conditioner
should be no more than 4 ft (122 cm) from a grounded outlet.
■ Be sure the wall where the air conditioner will be installed will
support the weight of the unit.
■ Do not install the air conditioner where the plastic cabinet
front will be exposed to a heat source that raises the surface
temperature above 120ºF (49ºC).
■ Do not block the louvers in the front panel.
1. Measure the existing wall sleeve.
If you choose to install the air conditioner yourself, read all
installation instructions, as well as the electrical requirements and
operating instructions, before installing your unit. This will help to
avoid any installation problems and will help ensure trouble-free
performance of your new air conditioner.

AIR CONDITIONER USE
Operating your air conditioner properly helps you to obtain the
best possible results.
This section explains proper air conditioner operation.
IMPORTANT:
■ If you turn off the air conditioner, wait at least 3 minutes
before turning it back on. This keeps the air conditioner from
blowing a fuse or tripping a circuit breaker.
■ Do not try to operate your air conditioner in the cooling mode
when outside temperature is below 66°F (19°C). The inside
evaporator coil will freeze up, and the air conditioner will not
operate properly.
Starting Your Air Conditioner
NOTES:
■ In the event of a power failure, your air conditioner will
operate at the previous settings when the power is restored.
■ If the electronic control will not respond to touch pad or
remote control commands, it is necessary to unplug the air
conditioner from the electrical outlet for 5 seconds before
plugging back in.
