1. determine the moving position of the air conditioner and whether the length of the pipe is sufficient. whether the placement position of the air conditioner is suitable and meets various requirements, etc. the relocation of the air conditioner also needs to meet the requirements of the general installation position of the air conditioner. it is necessary to investigate whether the environmental location is suitable for transferring the air conditioner, and then prepare the required materials and equipment. including a set of refrigeration repair tools and expansion screws for fixing indoor and outdoor units. there are also pipelines that need to be updated, extended, etc.
2. recover refrigerant: collect the refrigerant in the air conditioner into the outdoor unit. before dismantling the machine, start the air conditioner and set the refrigeration state with the remote controller. after the compressor operates for 5-10 minutes and the refrigeration state is normal, screw off the protective cap on the interface between the liquid pipe and the gas pipe of the external machine with a wrench, close the stop valve of the high-pressure pipe (fine), and immediately close the stop valve of the low-pressure pipe (coarse) after 1 minute of condensation on the surface of the pipe. in the same way, shut down quickly and unplug the power plug, tighten the safety cap with a wrench, and the refrigerant recovery is completed. the forced start button on the indoor unit can also be used to start the machine, and observe whether there are other faults in the indoor and outdoor units.
