CAUTION
Always install the indoor unit at level. If the
indoor unit is inclined, water may leak.
!
Be sure to completely
seal any gap with putty.
The connecting pipe, no
matter big or small,
should all be insulated
with insulation pipe and
then wrapped with vinyl
tape. (The insulator will
deteriorate if it is not
wrapped with tape).
Drain pipe must be installed
separately. Insulate indoor part
of pipe to prevent condensation.
The indoor piping should be
insulated with the enclosed
insulation pipe. (If the
insulator is insufficient,
please use commercial
products.)
