6-5 Piping insulation
• After the gas leak inspection is completed, refer to the following gures and use the included insulation
tube (3) and clamps (2) to apply the insulation.
Liquid pipe
Suction gas pipe
HP/LP gas pipe
Gas pipe
Liquid pipe
Indoor unit side
Outdoor unit side
BS unit
CAUTION
• Insulate all of the piping including the liquid pipes, HP/LP gas pipes, suction gas pipes, gas pipes, and
the pipe connections for these.
Not insulating these pipes could result in water leaks or burns.
In particular, low-temperature gas ows in the HP/LP gas pipes during full cooling operation, so the same
amount of insulation as used for the suction gas pipes is required.
In addition, high-temperature gas ows in the HP/LP gas piping and gas piping, so use insulation that
can withstand more than 120°C.
• When reinforcing the insulation material in accordance with the installation environment, also reinforce
the insulation on the piping protruding from the unit.
Insulation material required for reinforcement work should be supplied in the eld.
For more information, refer to the Engineering data book.
