The recovered refrigerant shall be returned to the refrigerant
supplier in the correct recovery cylinder, and the relevant Waste
Transfer Note arranged. Do not mix refrigerants in recovery units
and especially not in cylinders. If compressors or compressor oils
are to be removed, ensure that they have been evacuated to an
acceptable level to make certain that flammable refrigerant does
not remain within the lubricant. The evacuation process shall be
carried out prior to returning the compressor to the suppliers.
Only electric heating to the compressor body shall be employed to
accelerate this process. When oil is drained from a system, it shall
be carried out safely.

WARNING:
To reduce the risk of fire, electric shock, or injury to persons,
read the Safety Precautions before operating this appliance.
Note:
If the air conditioner is turned off, wait 3 minutes before re-
starting. This allows pressure inside the compressor to equalize. Fail-
ure to follow these instructions may be harmful to your unit.
power supply voltage
If the power supplied to the unit is not within plus/minus 10% of
the specified rating, the unit may not function and the fuse may
blow.
noise level
Noise from the air conditioner will be louder at night than in the
daytime. This is because noise in the surroundings is comparatively
low at night. If you feel that noise of the air conditioner is too loud,
switch the thermostat to lower numbers.
energy saving ideas
The capacity of the room air conditioner must fit the room size for
efficient and satisfactory operation.
Install the room air conditioner on the shady side of your room.
Do not block air flow inside with blinds, curtains or furniture; or out-
side with shrubs, enclosures, or other buildings.
Keep blinds and drapes in other windows closed during the sunniest
part of the day.
Clean the air filter as recommended in the Care and Cleaning sec-
tion.
