3 Maintenance Cautions
If it is necessary to replace components, all the components used shall be made by manufacturer. Otherwise, the supplier shall not
bear the responsibility.
1. Maintenance of Electrical Parts
(2)When inspecting the circuit with power on, check if there is electric leakage for the metal component such as evaporator or condenser.
During inspection, do not touch the circuit so as to prevent electric shock.
(3)When inspecting the capacitor, ensure that the maintenance area is well ventilated. After conforming there is no refrigeration leakage,
discharge electricity of capacitor.
(4)Before replacing the component, cut of the power supply of the unit. .
(7)When servicing the hermetic parts, cut of the power of the unit before opening the sealing cover. If it is necessary to use power
supply, perform leak test to prevent potential danger.
(8)Do not replace the case which may affect the protective grade.
reach the requirement of the suppler.
2. Maintenance of Refrigeration System
(1) Do not lengthen or cut the connecting pipe.
(2) If the system component (such as evaporator, condenser, compressor, pipe) is needed to be serviced, discharge the refrigerant of the
system completely before maintenance.
(3) The parts used for replacement must be made by manufacturer.
(4) It is necessary to perform leak test before and after maintenance and ensure there is no leakage.
