●
Recommended materials: Phillips screwdriver, two 45# adjustable wrenches,
45# and 50# torque wrenches, 13# and 30# solid wrenches or socket
wrenches, new compressor, dryer filter, refrigerant reclaiming device,
refrigerant charging device, R410A refrigerant
Context
Components and working principle: The scroll compressor is composed of the air
intake and exhaust angle valves, oil pump, motor, and electric heating belt. Gas is
sucked from the outside and discharged from the position in the center. A
variable-frequency scroll compressor uses a frequency converter, and generates
different air volumes as the frequency changes, thereby increasing or reducing the
cooling and heating capacity. When the compressor operates at a high speed, it
generates a large heating or cooling capacity, which enables the room
temperature to quickly reach the preset temperature. When the room temperature
decreases to a value close to the preset temperature, the compressor frequency
automatically decreases to a certain level to meet the heating or cooling capacity
requirements and maintain the room temperature at a stable level.

● Reclaim or dispose of the refrigerant in accordance with local laws and
regulations. Do not discharge the refrigerant to the atmosphere. The
composition of R410A may change during the recycling process. Therefore, you
are not advised to refill the refrigerant to the cooling system.
● When replacing a compressor, avoid skin contact with the refrigerant or
lubricant to prevent frostbite or burns.
● Do not tilt the compressor during replacement to prevent lubricant leakage.
● Install a new compressor immediately after you remove the rubber plugs of the
suction inlet and exhaust outlet to prevent the moisture
