FINISHING
(1) Heat insulate the connections between pipes.
•
For rear, right, and bottom piping, butt the connection piping insu-
lation material against the indoor unit piping and fasten it with seal
A (UNIT B only) and vinyl tape so there is no gap.
•
For left and left bottom piping wrap the piping with cloth tape within
the range that encompasses the piping housing section at the rear
of the indoor unit.
(2) Push the bottom of the indoor unit against the wall and hook the
two pawls at the bottom of the indoor unit to the mounting plate
hooks. At this time, check the following:
•
Are the top and bottom hooks seated positively? Check by moving
the indoor unit forward, backward, left and right.
•
Is the indoor unit installed level and perpendicular?
•
For left rear piping, is the drain hose at the bottom of the wall hole
pipe?
(3) Temporarily fasten the connection cable along the connection pip-
ing with vinyl tape and wrap decorative tape around the part that is
visible from the body. For right, bottom, and left piping, securely
wrap the part coming from the body with decorative tape so that
the piping does not swell. (Overlap wrapping of outdoor parts about
1/3 of the width of the tape from the bottom of the piping so that
water will not enter.)
(4) Fasten the connection pipe to the outside wall with a saddle, etc.
(5) Fill the gap between the outside wall pipe hole and the pipe with
sealer so that rain water and wind cannot blow in.
(6) Fasten the drain hose to the outside wall, etc.
