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 conden-
sing 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.
REFRIGERANT PIPING CONNECTION (for S 30xx models)
• Align the centre of the pipes.
• Sufficiently tighten the flare nut with fingers, and then tighten it with a spanner and torque wrench
as shown (see fig. 19 and fig. 20).
• Select the correct tightening torque (shown table 1) in order to prevent the pipes, connecting pieces
and nuts from being damaged.
