Step 4: Prepare refrigerant piping
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.
Refer to the Refrigerant Piping Connection section
of this manual for detailed instructions on pipe flaring
and flare torque requirements, technique, etc.
NOTE ON PIPING ANGLE
Refrigerant piping can exit the indoor unit from four
different angles
•
Left-hand side
•
Left rear
•
Right-hand side
•
Right rear
Refer to figures below for details.
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 wall after installaiton. 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 affect 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 affect the unit's performance.
If refrigerant piping is already embedded in
the wall, do the following:
Step 1: Hook the indoor unit on the mounting
plate
1. Keep in mind that the hooks on the mounting
plate are smaller than the holes on the back of the
unit. If you find that you don't have ample room
to connect embedded pipes to the indoor unit,
the unit can be adjusted left or right by about 30-
50mm (1.18-1.95in), depending on the model.
Move to left or right
Step 2: Prepare refrigerant piping
1. Open and fix the position of the panel, then, open
the covers of the two lock blocks, unscrew the screw
showed in the picture below, then hold both sides of
the lower panel in the place marked "PULL", pull it
upwards to release the buckles, then take the lower
panel down.
Open the cover
and unscrew the
screw
