VII．Maintenance
The equipment must be shut down for maintenance, and the power supply must be cut
off. The operation can only be carried out after 3 minutes, otherwise there will be a risk of
electric shock. When the room temperature is lower than 2°C, the internal water must be
drained when the machine is shut down for a long time.
Regularly disassemble the filter gauze for cleaning and use a compressed air gun to blow
away the dust on the condenser (about 1 week is suggested and the air filter must not be
missing for a long time).
