. Maintenance
1. During the daily running, it is required to check all meter’s indication to be in normal range. Avoid rain or too much
moisture on electric components which would cause electricity shorting. If such problem is found, dry the
components with care.
2. Always monitor the working status of compressor and fan motor, make sure the running sound is normal. If there is
any strange noise or abnormal sound, switch off the machine and call professional maintenance service for checkup
and repair.
3.Thermal expansion valves and other refrigeration components such as drying filters, solenoid valves in the main
circuit should work normally. Filters, drying filters, main circuit solenoid valves in front of thermal expansion valves
，
at high pressure
，
the temperature difference between the inlet and outlet pipes should not be obvious
，
nor should there
be dew or frost on components. Replacement of refrigeration components or troubleshooting of refrigeration systems
must be done by professionals.
4. Always check the joints between various parts are tightened and firm, particularly the join bolts of electric
components and conducting wires cannot be of any loose or have moisture. Make sure the wiring is tightened and
firm.
5. Clean the surface of machine regularly to keep it clean. Do not use any detergent, organic solvent (e.g. Lacquer
Thinner) or other solvents containing acid or alkali to clean the painted surface.
6. Air filter should be cleaned regularly subject to the local working conditions. Normally it should be cleaned once a

7. Always check the condenser if there is dust or dirt on the surface. Clean the surface regularly with neutral warm
solution and soft brush. Avoid damage to the flakes.
8. Always check the joins in compressor compartment if there is obvious oil stains or not. If such oil stains found, it
indicates the cooling gas would be leaking. Call professional service for repair and redo vacuuming and gas filling.
9.The machine must be upright when loading or handling. If it needs to be inclined, the angle between the machine and
the ground is no more than 45degrees.
10. Do not open the cooling system if there is not a breakdown. It does not require adding with cooling gas or grease
because it’s a totally sealed-off system. If such adding is necessary, it should be handled by professional service.
