(5) The maintenance of the expansion valve is generally every 1 to 2 years to check whether its operation is normal and whether the opening degree is appropriate. If it is not normal, it should be replaced or properly adjusted in time.

(6) The maintenance of the refrigeration system piping. ①Pipe joints: check once a year, check the sealing situation with a leak detector. Refrigeration system connection pipe: check whether it collides with other parts, check whether the hose is aging or cracked, and generally replace the hose every 3 to 5 years.

(7) Inspection and maintenance of the transmission mechanism.

①V-belt. Check the tension and wear every 100h of use, and replace with new ones after 3 years of use.

Tensioner and bearing: Check once a year and add lubricant.

(8) Refrigeration oil replacement. Generally check or replace once every two years or so. When there is a large leak in the pipeline, the refrigerant should be inspected or refilled in time. During the use of the system, if there is replacement of parts, the remaining amount of refrigeration oil should be checked and the loss should be replenished, the total amount is 230±10ml.
