Piping Insulation - Fujitsu AUYG07LVLA Design & Technical Manual

ADAPTER INSTALLATION
Attach the adapters (accessories) to the ports on the gas pipe side of the indoor unit according to
the size of the pipe to be connected.
Apply the refrigeration compressor oil (or equivalent) used for the outdoor unit to the
attaching portion of the adapters.
Tighten the adapter using a torque wrench
according to the tightening torque values in the
table below.

PIPING INSULATION

(1) Install the coupler heat insulation (large and small) and insulation (long and short) on each pipe as
shown in the figures be ow.
(2) Attach the butting surface with no gap to eliminate any gap between the insulations.
(3) During the pipe insulation work, prevent air from getting inside the insulation with an adhesive tape
