ATTENTION
All refrigerant work and refrigerant piping should comply with the local legislation, standards
and codes and should only be done by qualified and skilled people.
To disconnect the couplings:
Step 1: Shut down the A/C unit and unplug the electrical power cord from the wall outlet.
Step 2: Wait five minutes for the line pressure between the indoor compressor unit and outdoor condensing
unit to equalize.
Step 3: Pull the male coupling handle up and toward the male coupling to the full back position.
Step 4: Retract the Release Sleeve on the female coupling to release the male coupling half from the female
half.
Step 5: To seal and protect from dust, reinstall the protective cap and plug.
