4.4. Installing heat insulation
Install the heat insulation material after performing a refrigerant leak check (see the In-
stallation Manual for the outdoor unit for details).
4.4.1. Coupler heat insulation
• Insulate by the coupler heat insulation (Accessories) around the gas pipe and liquid
pipe of indoor side.
• After installing the coupler heat insulation, wrap both end with vinyl tape so that there
is no gap.
• After affi xing the coupler heat insulation, secure it with 2 cable ties (large), one on
each end of the insulation.
• Make sure that the cable ties overlap the heat insulation pipe.

After checking for gas leaks (refer to the Installation Manual of the outdoor unit),
perform this section.
Install heat insulation around both the large (gas) and small (liquid) pipes. Failure to do
so may cause water leaks.
5. INSTALLING DRAIN PIPES
Do not insert the drain piping into the sewer where sulfurous gas occurs. (Heat
exchange erosion may occur.)
Insulate the parts properly so that water will not drip from the connection parts.
Check for proper drainage after the construction by using the visible portion of
transparent drain port and the drain piping fi nal outlet on the body.
Do not apply adhesive agent on the drain port of the body.
(Use the attached drain hose and connect the drain piping.)
Tighten with 2 wrenches.
