PIPING AND DRAIN HOSE INSTALLATION

Piping and drain hose forming
∗
Apply heat-insulation for both refrigerant pipe and drain hose surely so that no dewing generates inside of
the equipment. (Use polyethylene foam for insulating material.)
n
Cutting a hole
In case of installing the refrigerant pipes from
the rear:
1. Decide the hole position for piping at
180mm from the arrow mark (
ð
) on the
installation plate and drill a hole at a slight
downward slant toward outdoor side.
Pipe hole; dia.65mm: AP007-AP018 type
Pipe hole; dia.80mm: AP024 type
NOTE
• When drilling a wall that contains a metal lath,
wire lath or metal plate, be sure to use a pipe
hole brim ring sold separately.

Mounting the installation plate
n
When the installation plate is
directly mounted on the wall
1. Securely fit the installation plate onto the wall
by screwing it in the upper and lower parts to
hook up the indoor unit.
2. To mount the installation plate on a concrete
wall with anchor bolts, utilize the anchor bolt
holes as illustrated in the above figure.
3. Install the installation plate horizontally in the
wall.
CAUTION
When installing the installation plate with a mounting
screw, do not use the anchor bolt hole.
Otherwise the unit may fall down and result in
personal injury and property damage.
CAUTION
Failure to firmly install the unit may result in personal
injury and property damage if the unit falls.
• In case of block, brick, concrete or similar type
walls, make 5mm dia. holes in the wall.
• Insert clip anchors for appropriate mounting screws.
NOTE
• Secure four corners and lower parts of the installa-
tion plate with 6 mounting screws to install it.

1. Remove the front panel
The front panel must be removed for piping connections
in the left, bottom left, and rear left directions.
• Open the air inlet grille upward.
• Remove the four screws securing the front panel.
• Slightly open the lower part of the front panel,
and then pull the upper part of the front panel toward
you to remove it from the rear plate.
2. Die-cutting front panel slit
Cut out the slit on the leftward or right side of the front panel for the left or right connection and the slit on
the bottom left or right side of the front panel for the bottom left or right connection with a pair of nippers.
3. Changing drain hose
For leftward connection, bottom-leftward connection and rear leftward connection’s piping, it is necessary to
change the drain hose and drain cap.
Without changing the drain hose position, the indoor unit will not fit to the wall.
How to remove the drain hose
• The drain hose can be removed by removing the screw securing
the drain hose and then pulling out the drain hose.
• When removing the drain hose, be careful of any sharp edges
of steel plate. The edges can injuries.
• To install the drain hose, insert the drain hose firmly until
the connection part contacts with heat insulator, and
the secure it with original screw.
