to remain in the lines.
If air is mixed with the refrigerant, then it can be the cause of
abnormal high pressure in the refrigerant line, and may result in
an explosion and other hazards.

Wireless Remote-Controller
When using the wireless remote controller, point it towards the receiver on the indoor unit.
If the remote controller is operated within approximately two minutes after power is supplied
to the indoor unit, the indoor unit may beep twice as the unit is performing the initial automatic
check.
The indoor unit beeps to confirm that the signal transmitted from the remote controller has
been received. Signals can be received up to approximately 23ft.(7m) in a direct line from the

cent lights and strong light can affect the ability of the indoor unit to receive signals.
If the operation lamp near the receiver on the indoor unit is blinking, the unit needs to be in-
spected. Consult your dealer for service.
Handle the remote controller carefully! Do not drop the remote controller or subject it to strong
shocks. In addition, do not get the remote controller wet or leave it in a location with high hu-
midity.
To avoid misplacing the remote controller, install the holder included with the remote controller
on a wall and be sure to always place the remote controller in the holder after use.

When the outdoor temperature is low and the humidity is high, frost
may form on the outdoor unit. If this occurs, the outdoor unit performs a
defrosting operation. Normal operation should begin after approximate-

A cracking or creaking sound is heard. These sounds can be heard when parts rub against each due to expan-
sion and contraction from temperature changes.
The room has an unpleasant odor. The indoor unit draws in air that contains gases produced from the
walls, carpeting, and furniture as well as odors trapped in clothing, and
then blows this air back into the room.
A white mist or vapor is emitted from the indoor unit. If the indoor temperature and the humidity are high, this condition may
occur when operation starts.

Warm air blows from the indoor unit intermittently when heating mode
is off or during fan mode. When another indoor unit is operating in heating mode, the control valve
opens and closes occasionally to maintain stability in the air conditioning
system. This operation will stop after a while.
* If this will cause an undesirable rise in the room temperature in small
rooms, etc., stop the operation of the indoor unit temporarily.
