5 REFRIGERANT PIPING

WARNING

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

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

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

•If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gas may generate.

REQUIREMENT

When the refrigerant pipe is long, set the support brackets to fix the pipe with 2.5 to 3m intervals. If the pipe is not fixed, abnormal sound may generate.

Be sure to use the flare nuts attached to the indoor unit or those for R410A.

Permissible pipe length and permissible height difference

They are different according to the used outdoor unit. For details, refer to the Installation Manual attached to the outdoor unit.

2.Insert a flare nut into the pipe, and flare the pipe.

As the flaring sizes of R410A differ from those of refrigerant R22, the flare tools newly manufactured for R410A are recommended.

However, the conventional tools can be used by adjusting projection margin of the copper pipe.

*In case of flaring for R410A with the conventional flare tool, pull it out approx. 0.5 mm more than that for R22 to adjust to the specified flare size.

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