● Check if the function keys of the controller can work well.
● Check if the drainage system can work well.
● Check if the system can work well after starting up.
● Check if the water outlet temperature is in correct situation.
● Check if there is vibration or abnormal sound when the system is functioning.
● Check if the wind, noise and condensate water produced by the system affect the environment
around.
● Check if there is refrigerant leakage.
● If any Error codes occur, please check the instructions for the detailed info.
8. Operation and maintenance
8.1 To ensure the well functioning, the system should be checked and maintained after a
period of time. During the maintenance, please pay attention to some points below:
● When you need open the cabinet and make inside inspection, please do cut off the electricity
power in advance.
● To ensure the stable running, please do not adjust any setting.

● Examine regularly the reliability of the electrical components, change all the failed or unreliable
components on time.
● The dirt retention on the surface of evaporator fin should be cleaned every 6 months.
● After long downtime, if we restart the equipment, we should make following preparations: examine
and clean the equipment carefully, clean the water pipeline system, examine the water pump, and
fasten all the wire connections.
● Replacement parts must use the original accessories, can not be replaced by other similar
accessories.
8.2 Refrigerant filling
Examine the refrigerant filling condition through reading the data of gauge, also the air suction and
exhaust pressure. If there is leakage or changing components of the refrigeration circulation system,
please ask for the assistant of professional technicians.
8.3 Leak detection
During leak detection and air tightness experiment, never let the refrigeration system filling oxygen,
ethane or other flammable harmful gas, we can only adopt compressed air, fluoride or refrigerant for
