8 System Operation and Maintenance
Troubleshooting
Replace the compressor.
Repair the leakage points and re-
wrap thermal insulation foam.
If there are oil stains, check whether
the suction and discharge pressure
of the compressor is within the
normal ranges. If the pressure is
beyond the normal range, contact
technical support.
● If drops of water are evenly
distributed, wipe off them with a
dry cloth.
● If there are large water marks,
close the water inlet sluice and
process the leak points. If the
thermal insulation foam is
damaged or missing, lay out new
thermal insulation foam.
Replace the refrigerant pipe support
and secure it again.
Replace the fan.
Take out the foreign matter.
Tighten the screws using a 10#
socket wrench.
If the heat exchanger core is
seriously damaged, replace it.
