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.

MOUNTING THE ANCHOR NUT AND
BOLT
• Prepare 4 suspension bolts. (Each bolts
length should be same.)
• Measure and mark the position for the
Suspension bolts and the piping hole.
• Drill the hole for anchor nut on the ceiling.
• Insert the nuts and washer onto the
suspension bolts for locking the suspension
bolts on the ceiling.
• Mount the suspension bolts to the anchor-
nuts firmly.
• Secure the hangers onto the Suspension
bolts (adjust level roughly.) using nuts,
washers and spring washers.
• Adjust a level with a level gauge on the
direction of left-right, back-forth by adjusting
suspension bolts.
• Adjust a level on the direction of top-bottom
by adjusting supension bolts. Then the unit
will be declined to the bottomside so as to
drain well.

• 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
• If converging multiple dranin pipes, install according to the procedure shown below.
• After piping work is finished check drainage flows smothly.
• Be sure to insulate all indoor units.
Heat insulation material: Polyethylene foam with
thickness more than 10 mm.
Slope downwards at a gradient
of at least 1/100
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.
