Note: The alarm output port is connected with a set of normally open and normally closed
contacts of the relay inside the machine. The working current should be smaller than 3A while
the working voltage should be smaller than 300V.
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).
