Four angles to exit
the piping
Step 1：
Based on the position of the wall hole relative
to the mounting plate, choose the side from
which the piping will exit the unit. You have four
options for the exit direction of the piping.
NOTE ON PIPING CONNECTING
In some locations of US, a conduit tube must be
used to connect the cable. To ensure an enough
space for the pipes running and the machine is
against the wall after installation, It is
recommended to attach the drain hose to the
right-hand side (when you're facing the back of
the unit).
When choose Left-hand side or Right-hand
side piping, please make sure that the pipes
come out horizontally so as not to a ect the
lower panel installation.
CAUTION
Be extremely careful not to dent or damage the piping while bending them
away from the unit. Any dents in the piping will a ect the unit's performance.
