Maintenance
3. AC outdoors radiator-―condenser‖ must be
cleaned regularly; refer to figure 5.
Treatment method: dismantle condensing fan,
condenser is completely exposes, wash with
water, but do not use high water pressure to
avoid lodging of condenser fan and affect
radiation effect;
Maintenance standard: wash once a month in
summer, if working environment is too bad,
increase washing times properly.
4. Check if fixed bolts of compressor are loosed
regularly, if belt of compressor is loosed; refer to
figure 6.
Checking method: visually check if AC bolts are
loosed, checking method of belt tightness
degree: put about 10kg force on middle of belt,
force is downward, descending amplitude of belt
is about 10-15mm, it cannot be too high or too
low; maintenance standard: check once a week
in summer.
5. Check if there is refrigeration agent in the
system
Checking method: check Freon injection mouth
of compressor head (refer to the picture), screw
off plastic plug, poke with keys or other sharp
things (its structure is like the air tap of tyre),
check if there is large amount of air jets out, if
there is no air or air current is very small, it
proves that Freon is leaked (wear gloves and
protect eyes during operation, do not burn skin
and eyes with refrigeration agent).
