3.3.3. Leveling
Using a level, or vinyl hose fi lled with water, fi ne adjust so that the body is level.
Inclined installation so as the drain pipe side is higher may cause a malfunction of the fl oat
switch, and may cause water leakage.

3.3.4. Installing drain pipe
WARNING
Do not insert the drain piping into the sewer where sulfurous gas occurs. (Heat ex-
change erosion may occur)
Insulate the parts properly so that water will not drip from the connection parts.
Check for proper drainage after installation by using the visible portion of transparent
drain port and the drain piping fi nal outlet on the body.
CAUTION
Do not apply adhesive agent on the drain port of the body. (Use the attached drain
hose assembly to connect the drain piping)
Note: Install the drain pipe.
• Install the drain pipe with downward gradient (1/50 to 1/100) and so there are no rises or
traps in the pipe.
• Use general hard polyvinyl chloride pipe (VP25) [outside diameter 32mm] and connect it
with adhesive (polyvinyl chloride) so that there is no leakage.
• When the pipe is long, install supporters.
• Do not perform air bleeding.
• Always heat insulate indoor section of drain pipe.
• If it is impossible to have suffi cient gradient of pipe, perform drain lift-up.

When lifting up drain:
• Height of inclined pipe should be less than 700 mm from the ceiling. A rise dimension
over this range will cause leakage.
• Lift up the pipe vertically at the position of 300 mm or less from the unit.

Installation procedure
1) Install the attached drain hose to the drain port of the body. Install the hose band from
the top of the hose within the shown in the fi gure area.
2) Use vinyl adhesive agent to glue the drain piping (PVC pipe VP25 ) to the drain hose
assembly.
(Apply color adhesive agent evenly until the gauge line and seal)
3) Check the drainage. (See separate diagram)
4) Install the heat insulation.
5) Use the attached heat insulation to insulate the drain port and hose band.

Check for drainage
Pour about 1 liter of water from the position (see 9. TEST RUN/CHECKING DRAINAGE).
Check for any abnormalities such as strange noises and whether the drain pump functions
normally
