Prepare refrigerant piping
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.
Four angles to exit
the piping
connect the indoor unit’s refrigerant piping to
the connective piping that will join the indoor
and outdoor units. Refer to the Refrigerant
Piping Connection section of this manual for
detailed instructions.
CAUTION
Be extremely careful not to dent or damage the piping while bending them
away from the unit. Any dents in the piping will aect the unit’s performance.

The refrigerant piping is inside an insulating sleeve attached to the back of the unit. You must prepare
the piping before passing it through the hole in the wall.

If the wall hole is behind the unit, keep the
knock-out panel in place. If the wall hole is to
the side of the indoor unit, remove the plastic
knock-out panel from that side of the unit.Use
needle nose pliers if the plastic panel is too
dicult to remove by hand.

When choose Left-hand side or Right-hand
side piping, please make sure that the pipes
come out horizontally so as not to aect the
lower panel installation.
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).
If need to cut the big size plastic
panel, cut as shown above.
Use the holder at the back of the unit to
prop up the unit, giving you enough room
to connect the refrigerant piping, signal cable,
and drain hose.
