4 Routine Maintenance
Troubleshooting
If the white paper becomes dirty, clean
up the dust, especially from the air filter
on the front door, or replace the air filter.
If any metal component suffers from
severe oxidation, remove the rust or
replace the component in a timely
manner.
If the component is painted, repaint it
after removing the rust.
Troubleshooting
If the temperature deviation is
greater than 1° C or humidity
deviation is greater than 5%,
the T/H sensor must be
calibrated or replaced.
Use a fin brush to organize the
fins that are pushed down.
If leaking points are found,
retrieve the refrigerant and
weld the leaking points again.
For details, contact Huawei
technical support.
If the white paper becomes
dirty, remove the dust on the
smart cooling product cabinet.
Troubleshooting
If the PoE port connection and
power supply in the smart ETH
gateway is not normal, check
whether the communications cable
is loose or disconnected. If so,
reconnect the cable. If not, replace
