●
Do not insert the knife more than 1-3/16inch
(30mm) into the insulation (Polystyrene) when
cutting off the insulation.
Do not cut off the
A
part in Fig. 2.
●
Do not use any tools which produce a lot of
swarf such as a saw for the opening work.
The drain pipe can become clogged and
cause water leakage.
(2) Place the insulation A and B to cover the entire gap between the side plate and the insulation (Polystyrene).
Attach the insulation A to the left and right of the opening and the insulation B to the top and bottom of
the opening.
Be careful not to cover the screw hole at the indoor unit side during placement.
