Piping Insulation - Daikin BSF4Q54TVJ Manual Del Usario

5-5 Piping insulation

• After the gas leak inspection is completed, refer to the following figures and use the included insulation
tube (Accessory (2)) and clamps (Accessory (1)) 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 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. In case of
an abnormal condition leading to system shut down, the pipe may experience temperatures around
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.
• If the taping or clamps of the insulation material is tightly wound, the thickness of the insulation mate-
rial will decrease and it will lead to deterioration of the insulation performance.
• In case of chaniging the control box position of a BSF4Q unit, there is the possibility that attaching
insulation material to the outdoor side piping will be difficult due to a narrow space.
In this case, temporarily remove the control box from the unit to secure the working space.
