The indoor unit installation
Installation Manual 21
ENGLISH
Be sure to give insulation work to refrigerant piping by covering liquid pipe and gas pipe separately
with enough thickness heat-resistant polyethylene, so that no gap is observed in the joint between
indoor unit and insulating material, and insulating materials themselves. When insulation work is
insufficient, there is a possibility of condensation drip, etc. Pay special attention to insulation work to
ceiling plenum.
