the air conditioner user manual.
If the sight glass completely
turns yellow, there is too much
water in the pipe. To solve the
problem, discharge refrigerant
from the pipe, vacuumize the
system, drain out water, and then
charge new refrigerant.
If the sight glass does not
obviously turn green, use a blow
drier to blow wind to the filter
until the sight glass turns green.
Check whether the air suction and
exhaust pressure of the compressor
is within the normal ranges. If no,
contact Huawei technical support.
If drops of water are evenly
distributed, wipe off them with a
dry cloth.
If there are dense water stains,
identify the leakage point, close
the water inlet sluice, and repair
the leakage point.
Replace the thermal insulation foam
if it is damaged or missing. For
details, see
6.2.6 Replacing a
Thermal Insulation
Layer.
Replace the faulty fan by following
instructions in the air conditioner
user manual.
Take out the foreign matter if the

Tighten the screws using a 10#
