Installation method

Refrigerant pipe work

Insulating the pipes

ffMake sure to insulated the refrigerant pipes with an insulation tape. If the pipe is not insulated, condensate may form and drop into the indoor.

ffWind the refrigerant pipes and the drain hose with vinyl tapes.

ffWhen you bend the pipe, try to secure large bending radius (over 100 mm) to prevent the copper pipe from distorting.

ffUse foamed polyethylene or EPDM foam, with thickness over 7 mm, as an insulator.

fIfthe pipe is installed in a place with humidity over 80 % (such as within a pit of a building, basement, sea shore, near hot spring or lake etc), use an insulator with a thickness over 10 mm.

Drain hose

ffInsulate the high pressure (liquid pipe)/low pressure (gas pipe) pipe, and finish it by winding up the vinyl tape around it.

ffMake sure to insulate the pipe with no gap or cracks, and use adhesive between the connection part of the insulator to prevent moisture from entering.

ffMake sure that the thickness of the insulator doesn’t get thinner on the bending part of the pipes. ffUse extra insulator to secure thickness when the insulator becomes thinner.

ffWhen the pipe hanger is installed, wind the extra PE Foam type insulator (over 5 mm) with the width 3 times wider than the hanger. (Do not use cable tie as an hanger.)

Oil trap

Check the following list and install an oil trap.

ffInstall an oil trap only when the outdoor unit is at a higher level than the indoor unit. ffBased on cooling operation, install it on the gas side pipe only.

ffInstall the oil trap only in between the outdoor unit and the first branch joint and it should be installed at every 10 m. ffRadius of curvature (R) on the oil trap are as follows:
