2) When connecting the drain pipe to the unit, pay suffcient attention not to apply excess force to the piping on the unit side.
Also, fix the piping at a point as close as possible to the unit.
3) For drain pipe, use hard PVC ganeral purpose pipe VP-25 (I.D.1'')
which can be purchased locally. When connecting, insert a PVC

e) After ensuring the above, secure the unit.
2) When embedded into ceiling
a) Install the unit following steps b) and c) of the above part 1).
b) When installing on a conventional ceiling, cut an installation opening (740 mm X 600 mm) in the ceiling.
c) Check the installation height and level, and after that, secure the unit.
