9.2.1 Monthly Maintenance

Issue 03 (2021-04-20)
Exercise caution during professional maintenance. For details, contact
technical support.
When replacing a component, do not lean the component against the
cabinet.
Softened water is used for circulation in the water tank in summer. The water
quality should meet the requirements.
The circulating water system is full of water in summer. When the unit is not
used in winter, drain the water from the water pipes to avoid freezing.
When a fan of the unit is faulty, shut down the unit immediately for repair. If
the fan cannot be repaired within two hours, use a baffle plate to block the
air vent after removing the fan to prevent air backflow.
After installing the smart cooling product, if the construction company is still
in the process of construction, take protective measures to prevent sundries
and dust from falling into the smart cooling product.
It is recommended that the following maintenance items be performed every
three to six months. The actual maintenance period depends on the loads and
surrounding conditions.
– Check the tightness of the bolts.
– Check the sealing strip of the maintenance door and the flexible
connector of the air duct. If there is any air leakage, replace them in time.
It is recommended that the following maintenance items be performed once a
year.
– Check electrical cable connections.
– Check whether the enclosure of the smart cooling product is damaged or
corroded. If yes, clean the shell and take anti-corrosion measures.
Check whether the gap between the impeller and the flow deflecting ring of
the fan is even, to prevent the impeller from colliding with the flow deflecting
ring.
After the unit stops running in a cold area or winter, check that the return air
damper/return air fire damper and supply air damper/supply air fire damper
are closed, and drain all water in the circulating water system.
