The indoor unit installation

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.
