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 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 unit, if the construction or decoration company is still in
the process of construction, take protective measures to prevent sundries and
dust from falling into the unit.
If the unit is deployed outdoors, do not open its maintenance door or electric
control box door in rainy days. In case of emergency, take rain-proof
measures.
It is recommended that the following maintenance items be performed every
three to six months. The actual maintenance interval 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.
