Drainage

1. Run the drain hose slopping downward.

NOTE

• The hole should be made at a slight downward slant on the outdoor side.
• The drain is internally trapped. An external trap is not required.

Do not rise the
drain hose.

Do not form the
drain hose into
a wavy shape.

Do not put the

2. Put water in the drain pan and make sure that the water is drained out.
3. When connecting an extension drain hose, insulate it with shield pipe.

Inside the room

Arrange the drain pipe for proper drainage from the unit.
Improper drainage can result in dew-dropping.

This air conditioner has the structure designed
to drain water collected from dew, which forms
on the back of the indoor unit, to the drain pan.
Therefore, do not store the power cord and other
parts at a height above the drain guide.

Remote control

• Place the remote control away from obstacles (such as curtain) that may

block the signal coming from the remote control.

• Do not install the remote control in a place exposed to direct sunlight or

close to a heating source such as a stove.

• Keep the remote control at least 3.3 ft (1 m) apart from the nearest TV set

or stereo equipment. (This is necessary to prevent image disturbances or
noise interference.)

• The location of the remote control should be determined as shown below.

Evacuating

After the piping has been connected to the indoor unit, you vacuum both
units at once.

Be sure to use a vacuum pump with counter-

ow prevention function so

that inside oil of the pump does not

ow backward into pipes of the air

conditioner when the pump stops.
(If oil inside of the vacuum pump enters the air conditioner, which uses
R410A, refrigeration cycle trouble may happen.)
1. Connect the charge hose from the manifold valve to the service port of

the packed valve at the gas side.

2.  Connect the charge hose to the port of the vacuum pump.
3.  Open fully the low pressure side handle of the manifold valve gauge.
4.  Operate the vacuum pump to start evacuating. Perform evacuation for

about 15 minutes if the piping length is 66 feet (20 m). (assuming a
pump capacity of 27 liters per minute) Then con

rm that the compound

pressure gauge reading is –101 kPa (–76 cmHg).

Using a vacuum pump

Evacuate the air in the connecting pipes and in the indoor unit using a
vacuum pump. Do not re-use the refrigerant in the outdoor unit. For details,
see the vacuum pump manual.
