1) Piping
position
2) Piping connection position
Piping can be connection from 3 different directions. Remove the cutout from hole where the piping will be connected using
side cutters or similar tool. Cut a hole for the piping connection in the back cover according to the cutting margin shown.
Cut a hole in the ceiling side in accordance with the position of the piping. Also, after the piping is installed, seal the space
around the piping with putty, etc. to keep dust from getting inside the unit.
(In order to prevent damage to wires from the edges, be sure to use the back cover.)
(If the connection is on the left
side, reverse the slope.)
(The figure shows the case where the
drain hose is on the right side.)

(f) Drain
piping
1) Drain piping can be connected from the back, right and left sides.
2)
When installing drain piping, be sure to use the insulating material supplied for the drain hose and drain
hose clamp.
a)
Connect the drain hose fully all the way to the base of the fitting.
b)
Fasten the hose securely with the drain hose clamp.
c)
Keep strictly within the lengths specified below for the suspension bolts.
3)
If drain piping is installed on the left side, change the rubber plug and insulating material (tubular) from
the left side piping connection port to the right side.
Be careful that water doesn’t pour out when the drain plug is removed.
3)
In order to make it easier for water to drain out, install the unit so that the water drain side slopes down-
ward.
Left-right direction
Front-rear direction
If the slope is reversed, there is danger of water leaking out.
