WARNING
Do not install outdoor unit near handrail of veranda. When installing air-conditioner unit on veranda of a high rise building, child may climb up to outdoor unit and
cross over the handrail causing an accident.
Do not use unspecifi ed cord, modifi ed cord, joint cord or extension cord for power supply cord. Do not share the single outlet with other electrical appliances. Poor
contact, poor insulation or over current will cause electrical shock or fi re.
Do not tie up the power supply cord into a bundle by band. Abnormal temperature rise on power supply cord may happen.
Do not insert your fi ngers or other objects into the unit, high speed rotating fan may cause injury.
Do not sit or step on the unit, you may fall down accidentally.
Keep plastic bag (packaging material) away from small children, it may cling to nose and mouth and prevent breathing.
When installing or relocating air conditioner, do not let any substance other than the specifi ed refrigerant, eg. air etc mix into refrigeration cycle (piping). Mixing
of air etc. will cause abnormal high pressure in refrigeration cycle and result in explosion, injury etc.
Do not add or replace refrigerant other than specifi ed type. It may cause product damage, burst and injury etc.
• For R410A model, use piping, fl are nut and tools which is specifi ed for R410A refrigerant. Using of existing (R22) piping, fl are nut and tools may cause abnormally
high pressure in the refrigerant cycle (piping), and possibly result in explosion and injury.
•
Thickness or copper pipes used with R410A must be more than 0.8 mm. Never use copper pipes thinner than 0.8 mm.
•
It is desirable that the amount of residual oil less than 40 mg/10 m.
Engage authorized dealer or specialist for installation. If installation done by the user is incorrect, it will cause water leakage, electrical shock or fi re.
Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock or fi re.
Use the attached accessories parts and specifi ed parts for installation. Otherwise, it will cause the set to fall, water leakage, fi re or electrical shock.

Ventilate if there is refrigerant gas leakage during operation. It may cause toxic gas when the refrigerant contacts with fi re.
This equipment must be properly earthed. Earth line must not be connected to gas pipe, water pipe, earth of lightning rod and telephone. Otherwise, it may cause
electrical shock in case of equipment breakdown or insulation breakdown.
CAUTION
Do not install the unit in a place where leakage of fl ammable gas may occur. In case gas leaks and accumulates at surrounding of the unit, it may cause fi re.
Do not release refrigerant during piping work for installation, re-installation and during repairing refrigeration parts. Take care of the liquid refrigerant, it may
cause frostbite.
Do not install this appliance in a laundry room or other location where water may drip from the ceiling, etc.
Do not touch the sharp aluminium fi n, sharp parts may cause injury.
Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage the furniture.
Select an installation location which is easy for maintenance.
Power supply connection to the room air conditioner.
Use power supply cord 3 x 2.5 mm 2 type designation 60245 IEC 57 or heavier cord.

gauge moves from 0 cmHg (0 MPa) to -76 cmHg (-0.1 MPa). Then evacuate the air
approximately ten minutes.
Close the Low side valve of the charging set and turn off the vacuum pump. Make sure
4.
that the needle in the gauge does not move after approximately fi ve minutes.
Note : BE SURE TO TAKE THIS PROCEDURE IN ORDER TO AVOID REFRIGERANT
GAS LEAKAGE.
5. Disconnect the charging hose from the vacuum pump and from the service port of the

CHECK THE DRAINAGE
Check after connecting the power supply.
• Pour approximately 600 cc of water into the drain pan of the
main unit using a squeeze bottle, etc. Heat
exchanger
• Press the drain test run switch on the control board in the
control box to start the drain motor and check whether the
water drains normally.
(The drain motor operates for approximately 5 minutes and
then stops automatically.)
(See the diagram for "Connecting the Indoor/Outdoor
Drain pan
Connection Cable".)
DISPOSAL OF OUTDOOR UNIT DRAIN WATER
• If a drain elbow is used, the unit should be placed on a stand which is
taller than 30 mm.
• If the unit is used in an area where temperature falls below 0˚C for 2 or 3
days in succession, it is recommended not to use a drain elbow, for the
drain water freezes and the fan will not rotate.
