Care and maintenance

Caution: Before performing any maintenance, turn off the main power to the system.

UnitFan coil

☐ Turn the system off before cleaning. To clean, wipe with a soft, dry cloth. Do not use bleach or abrasives.

Note:

Supply power must be disconnected before cleaning the unit.

Air Filter

The air filters (the suction side) should be checked and cleaned once every 2 weeks or more often if necessary.

Air outlet vent Air filters

□ Never use any of the followings:

• Water hotter than 40^ C Could cause deformation and/or discoloration.

• Volatile substances Could damage the surfaces of the air conditioner.

aces ONER POKING BING

1 Clean the filter with a vacuum or warm, soapy water.

- If very dirty, wash with a solution of detergent in lukewarm water.

2 After washing with water, dry well in the shade.

3 Re-install the air filter.

breaker when the air conditioner is not going to be used for a long time. Dirt may collect and may cause a fire.

When the unit is to be used again.

Check that the air inlet and outlet of the unit are not blocked.

Helpful information

The air filters and your electric 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.

Ventilate the room occasionally.

Since windows are kept closed, it is a good idea to open them and ventilate the room now and then.

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.

Installation of Unit

Install the unit above the ceiling correctly.

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.

CAUTION :

Tighten the nut and bolt to prevent unit falling.

1. Lift the fan coil unit to sufficient height.
2. Insert the suspended part of four suspension bolt in the four hangers provided on the side of main body one by one.
3. Lower the fan coil unit till the hangers rest on their respective flat washer.
4. Adjust the level in the top down direction by adjusting the suspension bolts. Inclined the fan coil unit as per direction provided in the fig

CAUTION

: Installation Information For Declination

1. Install declination of the fan coil unit is very important for the drain of the decorative type air conditioner.
2. Minimum thickness of the insulation for the connecting pipe shall be 10mm.
3. If the Installation Plates are fixed to horizontal line, the fan coil unit after installing will be declined to the bottomside.

Front of view

• The unit must be horizontal or inclined at angle.
• The inclination should be less than or equal to 1^ or in between 10 to 20mm inclined in drain direction as shown in fig.

Drain piping work

Ceiling Suspended

Lay the drain hose with a downward inclination so water will drain out.

• Always lay the drain with downward inclination (1/50 to 1/100).
Prevent any upward flow or reverse flow in any part.
- 10mm or thicker formed thermal insulator shall always be provided for the drain pipe.

Floor Standing

• 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 smoothly.
- 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.

ConnectingCabletotheFanCoilUnit

■ Connect the wires to the terminals on the control board individually according to the thermostat.

- Ensure that the color of the wires of unit and the terminal No. are the same as those of unit respectively.

CAUTION

The power cord connected to the unit should be complied with the following specifications (Rubber insulation, type H05RN-F approved by HAR or SAA).
