ATTENTION
If need suspending installation, the installation bracket should accord with all technical
requirements. The installation wall should be strong enough or actions to reinforce should be
taken. The connection between bracket and wall, bracket and the air conditioner should be firm,
stable and reliable. In case of any doubts or uncertainty do not attempt to install the unit but
have the support calculated and engineered by a skilled engineer.
CAUTION
• Do not allow the piping to let out from the back of the indoor unit.
• Be careful not to let the drain hose slack.
• Heat insulate both of the auxiliary piping.
• Be sure that the drain hose is located at the lowest side of the bundle. Locating at the upper
side can cause drain pan to overflow inside the unit.
• Never intercross nor intertwist the power wire with any other wiring.
• Run the drain hose sloped downward over the whole length to drain out the condensed water
smoothly.

CAUTION
After the confirmation of the above conditions, prepare the wiring as follows:
• Always have an individual power circuit specifically for the air conditioner. As for the method
of wiring, be guided by the circuit diagram posted on the inside of control cover.
• The screw 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 cause burn-out of
the wires.)
• Check specification of power source.
• Confirm that supplied electrical capacity is sufficient.
• See to that the starting voltage is maintained at more than 90 percent of the rated voltage
marked on the name plate.
• Confirm that the cable thickness is as specified in the power source specification.
• Always install an earth leakage circuit breaker.
• The following would be caused by voltage drop: Vibration of a magnetic switch, which will
damage the contact point, fuse breaking, disturbance of the normal function of the overload.
• The means for disconnection from a power supply shall be incorporated in the fixed wiring and
have an air gap contact separation of at least 3mm in each active(phase) conductors.

AIR PURGING (for S 30xx models)
Air and moisture that remain in the refrigerant system, e.g. after installation, can cause undesirable effects
or damage as indicated below:
• Pressure in the system rises.
• Operating current rises.
• Cooling or heating efficiency drops.
• Moisture in the refrigerant circuit may freeze and block capillary tubing.
• Water may lead to corrosion of parts in the refrigeration system.
• Damage of the compressor.
Therefore, the indoor unit and tubing between the indoor and outdoor unit must always be leak tested and
evacuated with aid of a vacuum pump to remove any noncondensables and moisture from the system.
PIPE LENGTH AND REFRIGERANT AMOUNT (for S 30xx models)
•When relocate the unit to another place, perform evacuation using vacuum pump.
• Make sure the refrigerant added into the air conditioner is in liquid form in any case.
• Only use the type of refrigerant as stated on the rating label.
ELECTRICAL SAFETY CHECK AND GAS LEAK CHECK
It is advised to do the following safety checks.
Electrical safety check
Perform the electric safe check after completing installation:
1. Insulated resistance
The insulated resistance must be more than 2MΩ.
2. Grounding work
After finishing grounding work, measure the grounding resistance by visual detection and grounding
resistance tester. Make sure the grounding resistance is less than 4 Ω.
3. Electrical leakage check (performing during test running)
During test operation after finishing installation, use an electroprobe and multimeter to perform the
electrical leakage check. Turn off the unit immediately if leakage happens. Check and find out the solu-
tion ways till the unit operate properly.
Gas leak check
1. Soap water method:
Apply a soap water or a liquid neutral detergent on the indoor unit connection or outdoor unit con-
nections by a soft brush to check for leakage of the connecting points of the piping. If bubbles come
out, the pipes have leakage.
2. Dedicated special leak detector
Use the leak detector to check for leakage.
