Excessively low temperature setting may be
harmful to health and will result in high power
consumption.
Cooling capacity can be reduced by
accumulated dirt on the air filter. Clean the air
filter when noise is heard or water drops
accumulate at the outlet.
Make sure windows and doors are properly
closed. Draft strips are recommended for use in
summer.
Window blind reduces 15% of sunlight and

regulated.
Voltage abnormal protection
Operation of the appliance will cease when
abnormalvoltagesareencountered.
The air filter must be regularly cleaned to prevent
wateraccumulationcausedbydirtblockage.
Desired temperature may not be reached for
restriction of ambient temperature or blockage of the
airfilter.

5.5Endingofinstallation
(2) Before connecting the tube, apply some refrigerant oil on
the surface of the flared tube and connections to prevent
airleakage.(Figure20)
After completion of wrapping and insulation, seal the hole on
the wall with a suitable sealant.

Place appliance A and then B. Air purging method is as
follows:
(1)Turndownthenutsonthewideandnarrowtubes.
(2) Loose the nut of the flared wide tube one complete turn
withaspanner.
(3) Turn counterclockwise to open the core of the valve with a
socket screw wrench. Some gas will come out from under
the nut of the flared end of the wide tube. Tighten the nut
10to15secondslater.
(4) Testfor leakage at the tube connector with soapy water or
a meter. If there is no leakage, turn counterclockwise to
open the tube core of the valve on the wide tube with a
