* Wrap the felt tape tightly around the pipes and hose starting near where the
pipes and hose are routed from the indoor unit. (The overlap width of the felt
tape should not be more than 1/2 of the tape width.)
C
Start wrapping the piping tape around the pipes and hose 10 mm inside the
indoor unit.
D
Fasten the end of the felt tape with a bandage stopper.
Cut and use the lower side panels on the left and right sides of the indoor unit as

Smooth the cut edges of the side panels so that they will not damage the insulation
coating. (Fig. 4-6)
E
Cut the lower side panels to match the height of the modelling.

drain water may not flow smoothly and some drain water may collect in the hose.
This can lead to a strange sound (burbling) being produced during strong winds
or when a ventilation fan, etc., is used in a residence that is well-sealed. If neces-
sary, contact your nearest Mitsubishi Electric representative for the optional parts
to prevent this problem.
