Forming The Piping

ing portion of the indoor unit with insula-
tion material and secure it with two kinds
of vinyl tapes.

the end of the drain outlet should be routed
above the ground. Secure the drain hose appro-
priately.
In cases where the outdoor unit is
installed below the indoor unit perform the
following.
• Tape the piping, drain hose and connecting
cable from down to up.
