If a refrigerant reclaiming pump is used, the requirements for using the pump must be met. Connect the refrigerant reclaiming pump to the outdoor unit needle valve and (if a low temperature component is deployed) the needle valve at the outdoor unit liquid pipe port of the lo...
When the pressure decreases to the atmospheric pressure and becomes stable, shut down the refrigerant reclaiming pump. Ensure that there is no pressure in the system and the refrigerant is completely reclaimed. Remove the electric heating belt. Remove the compressor. Use a flat-head insulated ...
