After the gas leak inspection is completed, refer to the following figures and use the included insulation
tube 3) and clamps 2) to apply the insulation.
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 operation,
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.

(Field supply)
Seal the connection.
Piping insulation
(Site piping side)
(1) Attach the included
insulation.
(2) Seal
(3) Use the clamps (accessory)
to hold both ends.
Note 1: For suction gas pipes, high/low
pressure gas pipes, and gas pipes,
after attaching the included
insulation tube, wrap more
insulation (field supply) around the
connections.
Note 2: For Model Q96, wrap sealing
material (field supply) around the
insulation tube 3)-2 Branch

Insulation Installation Precautions
1. Seal so that air cannot be in and out of the end.
2. Do not over tighten the clamp so as to maintain the insulation thickness.
3.
Be sure to attach the insulation (field supply) with the seams facing up.
(See figure at right.)
