5. Select the insulation of the refrigerant pipe.
Insulate the gas side and liquid side pipe referring to the thickness according to the pipe size.
Indoor temperature of 30°C(86°F) and humidity of 85% is the standard condition. If install in a high humidity condition, use one grade
thicker insulator by referring to the table below. If installing in an unfavorable conditions,use thicker one.
Insulator's heat-resistance temperature should be more than 120°C(248°F).

Refrigerant pipe before EEV kit and MCU or without EEV kit and MCU
You can contact the gas side and liquid side pipes but the pipes
should not be pressed.
When contacting the gas side and gas side pipe, use 1 grade thicker
insulator.
Refrigerant pipe after EEV kit and MCU
Install the gas side and liquid side pipes, leave 10mm(3/8") of
space.
When contacting the gas side and liquid side pipe, use 1 grade
thicker insulation.
• Install the insulation not to get wider and use the adhesives on the connection part of it to
prevent moisture from entering.
• Wind the refrigerant pipe with insulation tape
if it is exposed to outside sunlight.
• Install the refrigerant pipe respecting that the
insulation does not get thinner on the bent
part or hanger of pipe.
• Add the additional insulation
if the insulation plate gets thinner.
• Installez le matériau isolant de sorte qu'il ne s'élargisse pas et utilisez les adhésifs situés sur la pièce de
raccordement de celui-ci pour empêcher l'humidité de pénétrer.
• Enroulez le tuyau réfrigérant avec du ruban
isolant s'il est exposé à la lumière du jour.
• Installez le tuyau réfrigérant de manière à ce que
l'isolation ne s'affine pas au niveau de la partie
courbée ou du support du tuyau.
• Ajoutez du matériau isolant si la plaque
d'isolation devient plus fine.
