In these cases, take the following actions:
• Make sure that the ventilation fan for smoke-collecting
hood on a cooking table has sufficient capacity so that it
draws oily steam which should not flow into the suction
of the air conditioner.
• Make enough distance from a cooking room to install
the air conditioner in such a place where it may not suck in oil steam.
2. Avoid installing air conditioner in such circumstances where cutting oil mist or iron powder is in
suspension in factories, etc.
3. Avoid places where inflammable gas is generated, flows in, is stored or vented.
4. Avoid places where sulfurous acid gas or corrosive gas is generated.
5. Avoid places near high frequency generators.

Indoor Unit Drain Piping
• Drain piping must have down-slope (1/50 to 1/100): be sure
not to provide up-and-down slope to prevent reversal flow.
• During drain piping connection, be careful not to exert
extra force on the drain port on the indoor unit.
• The outside diameter of the drain connection on the
indoor unit is 32 mm.

Drain test
The air conditioner uses a drain pump to drain water.
Use the following procedure to test the drain pump operation:
Flexible drain hose
(accessory)
Main
drain pipe
Drain Pump
Drain
port
Glue the joint
Drain hose connection
Use the clip (accessory)
Drain pan
!
CAUTION
The supplied flexible drain hose should not
be strained. A strained hose may cause
leakage of water.
• Connect the main drain pipe to the exterior and leave
it provisionally until the test comes to an end.
• Feed water to the flexible drain hose and check the
piping for leakage.
• Be sure to check the drain pump for normal operation
and noise when electrical wiring is complete.
• When the test is complete, connect the flexible drain
hose to the drain port on the indoor unit.

CAUTION
After the confirmation of the above conditions, prepare the wiring as follows:
1) Never fail to have an individual power specialized for the air conditioner. As for the method of
wiring, be guided by the circuit diagram posted on the inside of control box cover.
2) Provide a circuit breaker switch between power source and the unit.
3) The screws which fasten the wiring in the casing of electrical fittings are liable to come loose
from vibrations to which the unit is subjected during the course of transportation. Check
them and make sure that they are all tightly fastened. (If they are loose, it could give rise to
burn-out of the wires.)
4) Specification of power source
5) Confirm that electrical capacity is sufficient.
6) Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage
marked on the name plate.
7) Confirm that the cable thickness is as specified in the power sources specification.
(Particularly note the relation between cable length and thickness.)
8) Never fail to equip a leakage breaker where it is wet or moist.
9) The following troubles would be caused by voltage drop-down.
• Vibration of a magnetic switch, damage on the contact point, fuse breaking, disturbance by the
normal function of an overload protection device.
• Proper starting power is not given to the compressor.
HAND OVER
Teach the customer the operation and maintenance procedures, using the operation manual.

Some products have no DIP switch on PCB. It is possible to set indoor units to Master or Slave by
using the wireless remote controller instead of DIP switch.
For the details of the setting, please refer to the manual of the wireless remote controller.
1. It is possible to 16 indoor units(Max.) by one wired remote controller.
Set only one indoor unit to Master, set the others to Slave.
2. It is possible to connect with every type of indoor units.
3. It is possible to use wireless remote controller at the same time.
4. It is possible to connect with Dry Contact and Central controller at the same time.
- The Master indoor unit is possible to recognize Dry Contact and Central Controller only.
5. In case that any error occurs at indoor unit, the error code is displayed on the wired remote
controller.
It is possible to control the other indoor units except the error units.
6. In case of Group Control, it is possible to use following functions.
- Selection of operation options (operation/stop/mode/set temperature)
- Control of flow rate (High/Middle/Low)
- It is not possible at some functions.

Airborne Noise Emission
The A-weighted sound pressure emitted by this product is below 70 dB.
** The noise level can vary depending on the site.
The figures quoted are emission level and are not necessarily safe working levels. Whilst there is a
correlation between the emission and exposure levels, this cannot be used reliably to determine
whether or not further precautions are required. Factor that influence the actual level of exposure of the
workforce include the characteristics of the work room and the other sources of noise, i.e. the number
of equipment and other adjacent processes and the length of time for which an operator exposed to the
noise. Also, the permissible exposure level can vary from country to country. This information, however,
will enable the user of the equipment to make a better evaluation of the hazard and risk.
Limiting concentration
Limiting concentration is the limit of Freon gas concentration where immediate measures can be
taken without hurting human body when refrigerant leaks in the air. The limiting concentration shall
be described in the unit of kg/m3 (Freon gas weight per unit air volume) for facilitating calculation
Limiting concentration: 0.44 kg/m3(R410A)
n Calculate refrigerant concentration
Total amount of replenished refrigerant in refrigerant facility (kg)
Refrigerant concentration =
Capacity of smallest room where indoor unit is installed (m3)

1. The data shown in the graph illustrates the supported operating ranges underthe following conditions:
- Indoor and Outdoor Unit
- Effective piping length: 7.5 m
- Height differential: 0 m
2. The actual temperature may not match the temperature setting under some circumstances due to the
outdoor-air processing load or mechanical protection controls.
3. The system will not operate in fan mode when the outdoor air temperature is -5 °C or below.
