2) When the machine stops due to faults, press down the main power switch first
(the alarming light goes out), then check the cause of the faults, the machine
should not be started forcibly before troubleshooting.
3) Do regular inspection inorder to prolong the lifespan of the system and avoid
the happening of accidents.
4) Because the high alkalescence will accelerate the rusting of copper pipe and
decrease the lifespan of the heat exchanger so it needs to do water quality
dispose for the system used water, the water PH value should be within the
range from 7.0 to 8.5.
5) Keep the machine room dry, clean and have good ventilation.
6) The daily operation, management and maintenance work should be carried
out by professionals. (Please notice that any disassembly or check during the
operation will be dangerous!)
7) In order to make sure the chiller is under good working performance, the user
should clean the condenser and evaporator timely to avoid furring
accumulation, and affect its heat exchange.
