PRECAUTIONS BEFORE INSTALLATION
CAUTION
Never use for special applications such as storing
food, plants, precision equipment or art.
Never use the unit in special environments.
• The quality of these items may deteriorate.
Always provide adequate signal noise protection when
installing in facilities such as hospitals and
communication stations.
• Equipment at these facilities, such as inverters, in-house
generators, high-frequency medical equipment, two-way
communication equipment, may cause the air conditioner
to operate improperly. Conversely, the signal noise from
the air conditioner may affect the operation of medical
equipment and two-way communication equipment and
this could interfere with the medical treatment being given
to patient's or cause disturbances or interference in video
broadcasting equipment.
• Special environments with high concentrations of oil,
steam or sulphuric gases will reduce the performance of
the air conditioning unit and cause its parts to deteriorate.
Never install the unit where run-off could result in
damage.
• If the humidity in the room exceeds 80% or if the drain
becomes clogged, water may drain off of the indoor unit.
When the unit is used for heating, there may be drainage
from the outdoor unit. If required, provide collector and
drain for the outdoor unit.
PRECAUTIONS BEFORE REMOVAL AND ELECTRIC WORK
CAUTION
Route wiring so that there is no tension.
Use care when transporting the unit.
• Tension could cause the wire to break and this could
result in excessive heat or fire.
• Always use two or more people for lifting a product
weighing 20 kg. or more.
• Some products are packaged with plastic wrapping bands.
Never use these for lifting or transporting the product.
• Never touch the fins on the heat exchanger. They are
sharp and could cause cuts.
• Never allow children to play with the plastic bags used for
packaging. Always tear them up when disposing. A child
could suffocate in these bags.
Dispose of packing materials properly.
PRECAUTIONS BEFORE TEST RUN
CAUTION
Never touch the switch with wet hands.
Never operate the air conditioner with the panel or
guard removed.
• Electric shock could occur.
• Due to the high risk of personnel injury through contact
with electrical, rotating and high temperature components.
Never operate the air conditioner with the air filter
removed.
• Particles will enter into the air conditioner and cause
damage.
Never turn off the power supply immediately after
stopping the unit.
• Wait five minutes or more before turning off the power
supply. Turning off the power supply before that time could
result in water leakage or damage.

1 Installing the Drain Pump
The Drain Pump must be fitted before installing the indoor unit.
1.Removing the Drain pan
(1) Remove the screw that fixes the
drain pan.
(2) Slide the drain pan in the direction
(a) , and unhook the drain pan
catch near the drain pipe.
(3) Slide the drain pan in the direction
(b) , and unhook the drain pan
catch on the other side.
(4) Remove the 2 screws that fix the
drain pan cover , and remove it.
2.Installing the Drain pump
(1) Use five PTT Screws D to fit the
Drain pump assy 1.
<Caution> At this time, fit the drain
sensor item 2 for group A
and B models only.
(2) Use two PTT Screws D to fit the
Pump cover assy 3.
(3) Use one PTT Screw D to fit the
Drain pan cover 45.
<Caution> At this time, install drain pan
cover 4 onto group A1, B1
and C1 models, and drain
pan cover 5 on group A2, B2
and C2 models.
(4) Install the drain hose set 8 onto the
drain socket. Insert the drain hose
into the socket, and fix with the hose
band. After connecting the drain
pipe, insulate with insulating pipe (fix
with the enclosed band).

(1) The drain piping should be set so that it has a
gradient of more than 1/100 from the discharge
side. Use care in routing the pipe so that no traps
or rises are formed in the layout. (Please refer to
Fig. 3-1)
(2) The drain should not extend for more than 20
meters laterally (not including the difference
between low and high points). In addition, if the
drain piping is long, make sure to use support
brackets along the way to eliminate dipping in the
piping. Don't connect to air leakage pipe. There are
times when the water will spurt out of the drain.
(3) Use hard vinyl piping for the drain piping. (This is
the common VP-25 type with an external diameter
of ø32.) Always use a vinyl-based adhesive at all
joints to prevent leakage.
(4) If there is a collector pipe, as shown in Fig. 3-2,
position the collector pipe 10 cm lower than the
drain port of this unit. In addition, make sure the
collector pipe has a gradient of more than 1/100.
(5) Do not install a vapor trap (odor lock) at the
discharge port of the drain piping.
(6) Carefully position the discharge port of the drain
pipe so that there will be no possibility of odors
being created.
(7) Do not insert the drain pipe into a sewer (soil) pipe.
(8) The mounting port for the drain pipe can be up to
500 mm higher than the lower surface of the indoor
unit. If there is some obstruction in the ceiling,
carefully route the drain pipe around it with minimal
rise. (Refer to Fig. 3-3)
(9) Always use the drain hose for the indoor unit that
has been provided. Do not apply unreasonable
force to the drain hose.
Caution: Keep the rise in the drain pipe to an
absolute minimum. If there is a long rise, water will
flow back when the power is turned off. If the unit
is left off for a season, fungus and alge could
develop and cause odors.
(10) Always use insulation on the drain pipe.

CAUTION
Route the drain piping so that it ensures proper drainage. Ensure that there is
enough warmth to prevent dewing. Improper piping insulation can result in water
leakage which could damage the area where the unit has been installed.

4 Confirm Drainage
Confirm that the DRAIN-UP system is operating properly in both heating and cooling cycles and
that drainage is being performed correctly. Also check during operation that there is no water
leaking from any of the joints.
* If the unit is being installed in a new site, it is best to do the installation before the ceiling is
built.
(1) Use a water feed pump or other method to pour some water into the drain pan. When
doing this, make sure that no water spills from the drain pan. Also use care not to
splash water on the drain pump or drain sensor at this time.
(2) Turn on the power for the indoor unit. Use the remote controller to select "Test
Operation" mode. (Refer to the Installation Manual provided with the indoor unit for
details.) Press the "Change Operation" button and set the unit to "Cooling." Confirm
that drainage is taking place by looking at the clear hose.
(3) After confirmation has been made, turn off the power. If it's during the heating season,
remove the Rubber plug and allow the water to drain out. Be sure to replace the plug
once the water has been drained out.
Please double check the installation.
