4 DRAIN PIPING WORK

Thermal insulating process

•After checking of the draining, using the supplied thermal insulation fit to the flexible hose leaving no clearance at the connecting port of the indoor unit.

•Fit locally procured thermal insulation to the drain pipe leaving no clearance between the supplied insulation.

5 REFRIGERANT PIPING

WARNING

•If refrigerant gas leaks during the installation work, ventilate the room immediately.

•If the leaked refrigerant comes in contact with fire, noxious gas may generate.

•After the installation work, confirm that refrigerant does not leak.

•If refrigerant gas leaks into the room and flows near to a source of fire, noxious gas may be generated.

CAUTION

Ensure water is poured slowly.

REQUIREMENT

When using long length of refrigerant piping. Provide support brackets at intervals of 2.5 m to 3 m. If the pipes are not fixed abnormal sounds may be generated.

Ensure the supplied R410A flare nuts are used.

Permissible pipe length and permissible height difference

This differs depending on the outdoor units. For details, refer to the Installation Manual supplied with the outdoor unit.

2.Place flare nut onto the pipe, and flare the pipe. (Use the flare nut fitted to the unit or one that is R410A compatible)

As the flaring sizes of R410A differ from that used on R22. It is recommended to use a dedicated R410A flaring tool. However a conventional flare tool can be used, by adjustment of the projection of the copper pipe.

*In case of flaring for R410A with the conventional flare tool, make a margin of 0.5 mm longer than that of R22 pipe so that the flare size matches with the specified size.

The copper pipe gauge is useful for adjusting the projection margin size.
