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

CAUTION
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.

Evacuating

After the piping has been connected to the indoor unit, you can vacuum both
units at once.
VACUUMING
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.
Using a vacuum pump
Be sure to use a vacuum pump with counter-fl ow prevention function so
that inside oil of the pump does not fl 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. Confi rm that the
compound pressure gauge reading is –101 kPa (–76 cmHg) and
500 microns or lower.
5. Close the low pressure side valve handle of the manifold valve gauge.

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.)
