Safety Precautions
Installation
After installing, the water
leakage test should be
perfrmed.
• A bad connection may cause
water leakage.
CAUTION
Install the drain hose to
ensure that water is drained
away properly.
• A bad connection may cause
water leakage.
Keep level even when
installing the product.
• To avoid vibration or water
leakage.
90°
Use two or more people to lift and transport
the product.
• Avoid personal injury.
Do not install the product where it will be
exposed to sea wind (salt spray) directly.
• It may cause corrosion on the product. Corrosion,
particularly on the condenser and evaporator fins,
could cause product malfunction or inefficient
operation.
Operation
Do not expose the skin
directly to cool air for long
periods of time.
(Don't sit in the draft.)
• This could harm to your health.
6 Fan Coil Unit
Do not use the product for
special purposes, such as
preserving foods, works of
art, etc. It is a consumer air
conditioner, not a precision
refrigeration system.
• There is risk of damage or
loss of property.

securely. Clean the filter
every two weeks or more
often if necessary.
• A dirty filter reduces the efficiency
of the air conditioner and could
cause product malfunction or
damage.

Re-install the air filter.
Care and maintenance
When the unit is not going to be used for a long time.
When it is not going to be used for
a long time.
1
When the unit is to be used again.
Operate the unit on Air circulation mode for
2 to 3 hours.
Check that the air inlet and outlet of the
unit are not blocked.
¥This will dry out the internal parts.
2
Turn off the circuit breaker.
Helpful information
CAUTION:Turn off the circuit
breaker when the air conditioner is not
going to be used for a long time.
Dirt may collect and may cause a fire.
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.
Operation Tips
Do not overcool the room.
This is not good for the health
and wastes electricity.
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.
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.
Ventilate the room
occasionally.
Since windows are kept
closed, it is a good idea to
open them and ventilate the
room now and then.

• Drain piping must have downward (1/50 to 1/100): be sure not to provide up-and-down slope to prevent reverse
flow.
• During drain piping connection, be careful not to exert extra force on the drain port on the fan coil unit.
• The outside diameter of the drain connection on the unit is 20mm.
• Be sure to install heat insulation on the drain piping
Heat insulation material: Polyethylene foam with
thickness more than 10 mm.
• If converging multiple dranin pipes, install according to the procedure shown below.
Slope downwards at a gradient
of at least 1/100
• After piping work is finished check drainage flows smothly.
• Be sure to insulate all indoor units.
CAUTION: 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.
