5-5 Piping insulation
• After the gas leak inspection is completed, refer to the following figures and use the included insulation
tube (2) and clamps (1) to apply the insulation.
Liquid pipe
Suction gas pipe
High/low pressure
gas pipe
Gas pipe
Liquid pipe
Indoor unit side
Outdoor unit side
Branch Selector unit
CAUTION
•
Insulate all of the piping including the liquid pipes, high/low pressure 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 flows in the high/low pressure gas pipes during full cooling opera

tion, so the same amount of insulation as used for the suction gas pipes is required.
In addition, high-temperature gas flows in the high/low pressure gas piping and gas piping, so use
insulation that can withstand more than 250°F (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 field.
For more information, refer to the Engineering Data Book.
