l purposes, such as preserving foods, works of art
, etc. It is a consumer air
conditioner
, not a precision
refrigeratio
n system.
• There is risk of damage or los
s of property.
Do not block the inlet or outle
t of air flow.
• It may cause product failure.
After installing, the water leakage test should be perfrmed.
• A bad connection may cause water leakage.

Operation Tips
Helpful information
The air filters and your electiric bill. If the air filters become clogged with dust, the cooling capacity will drop, and 6% of the electricity used to operate the air conditioner will be wasted.
When it is not going to be used for
a long time.
When the unit is to be used again.
Operate the unit on Air circulation mode for 2 to 3 hours.
This will dry out the internal parts.
CAUTION:
Turn off the circuit breaker when the air conditioner is not goingtobeusedforalongtime.
Dirt may collect and may cause a fire.
Check that the air inlet and outlet of the unit are not blocked.
Do not overcool the room.
This is not good for the health and wastes electricity.
Keep blinds or curtains
closed.
Do not let direct sunshine enter the room when the unit is in operation.
Make sure that the doors
and windows are shut tight.
Avoid opening doors and windows as much as possible to keep the cool air in the room.
Clean the air filter regularly.
Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects. Clean at least once every two weeks.
Ventilate the room
occasionally.
Since windows are kept closed, it is a good idea to open them and ventilate the room now and then.
Turn off the circuit breaker.

Has the fuse blown or has the circuit breaker been tripped?
Check that this is not a damp smell exuded by the walls, carpet, furniture or cloth items in the room.
Is the air filter dirty? See air filter cleaning instructions.
The room may have been very hot when the unit was first turned on. Allow time for it to cool down.
Are the indoor unit's air inlet or outlet vents obstructed?

CAUTION:
1. Install declination of the unit is very important for the drain of the duct type unit.
2. Minimum thickness of the insulation for the connecting pipe shall be 20mm.
• The unit must be horizontal or declined to the drain hose connected when finished installation.
• Always lay the drain with downward inclination (1/5

CAUTION:
CAUTION:
Make sure that the screws of the terminal fixed tightly.
Prepare the wiring as follows:
1) Never fail to have an individual power specialized for the unit. As for the method of wiring, be guided by the circuit diagram pasted on the side panel.
2) Provide a circuit breaker switch between power source and the unit.
3) 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 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 there of, fuse breaking, disturbance to the normal
function of a overload protection device.
