Notes Nominal cooling capacities are based on : indoor temperature : 27°CDB, 19°CWB, outdoor temperature
: 35°CDB, equivalent refrigerant piping : 7.5m (horizontal)
Nominal heating capacities are based on : indoor temperature : 20°CDB, outdoor temperature : 7°CDB,
6°CWB, equivalent refrigerant piping : 7.5m (horizontal)
Capacities are net, including a deduction for cooling (an addition for heating) for indoor fan motor heat.
Sound pressure levels are measured at 220V

11 - 1 Drainage instructions
Rig the drain pipe as shown below and take measures against
condensation. Improperly rigged piping could lead to leaks and
eventually wet furniture and belongings.
Install the drain pipes.
• Keep piping as short as possible and slope it downwards so that
the air does not remain trapped inside the pipe.
• The diameter of the drain pipe should be larger than or equal to
the diameter of the connecting pipe (Vinyl tube; pipe size: 25 mm;
outer dimension: 32 mm).
• Use the attached drain hose and clamp metal. Insert the drain hose
into the drain socket, up to the white tape. Tighten the clamp until
the screw head is less than 4 mm from the hose.
• Wrap the attached sealing pad over the clamp and drain hose to
insulate.
• Insulate the drain hose inside the building.
• Insulate the clamp and drain hose with the attached large sealing
pad. If the drain hose cannot be sufficiently set on a slope, execute
the drain raising piping. Secure a downward gradient of 1/100 or
more for the drain pipe. To accomplish this, mount supporting
brackets at an interval of 1 - 1.5 m.
Precautions when installing drain-up piping.
• Make sure the drain-up piping is maximum 330 mm high. Install
the drain-up piping horizontally, and make sure it is not further
than 300 mm from the base of the drain socket.
• Use the following outline if installing concentrated drain piping. If
converging multiple drain pipes, install according to the procedure
shown on the right.
Select converging drain pipes whose gauge is suitable for the operating capacity of the unit.
CAUTION
1 Installing the unit at an angle opposite to the drain piping might
cause leaks.

11 - 1 Drainage instructions
When piping work is finished
• Check if drainage flows smoothly. Open the inspection opening,
add approximately 1,000 cc of water slowly into the drain pan and
check drainage flow.
When electric wiring work is finished
• Check drainage flow during COOL running, explained under “TEST
OPERATION”
When electric wiring work is not finished
• Remove the electric parts box lid, connect power supply and
remote control to the terminals.
Next, press the inspection/test operation button on the
remote control. The unit will engage the test operation mode.
Press the operation mode selector button until selection
FAN OPERATION . Then, press the ON/OFF button .
The indoor unit fan and drain pump will start up. Check that the
water has drained from the unit. Press to go back to the
first mode.
NOTE
1 Use the drain outlet for maintenance to drain water from the
drain pan.
Inspection opening
Portable pump
Bucket Drain outlet for maintenance (with rubber plug)
CAUTION
1 Do not connect the drain piping directly to sewage pipes that
smell of ammonia. The ammonia in the sewage might enter the
indoor unit through the drain pipes and corrode the heat
exchanger.
