Drainage Test
1
Conduct a drainage test after completion of the electrical work.
2
During the trial, make sure that drain flows properly through the piping and that no water leaks from connections.
3
In case of a new building, conduct the test before it is furnished with the ceiling.
4
Be sure to conduct this test even when the unit is installed in the heating season.
Procedures
1
Supply about 1000 cc of water to the unit through the air outlet by using a feed water pump.
(
If the electrical work has not been completed, connect a convex joint in the drain pipe
connection to provide a water inlet.
Then, check if water leaks from the piping system and that drain flows through the drain
pipe normally.
2
Check at the exhaust port if drain is flowing.
(Note) Conduct this test paying attention to rotating sound of the drain motor.
3
Remove the drain plug located on the bottom of the drain pan when the water has to be evacuated from the unit.
4
After the test, fit the drain plug to the original place and turn off the power source.
(5) Fixing of Decorative Panel (The panel fixing bolts are attached on the panel.)
(a) Check with the accessory level gauges that the indoor unit height and the size of ceiling hole are correct.
¡
Remove the level gauges from the indoor unit before fixing the decorative panel.
(b) Screw two bolts out of four accessory bolts less than 5 mm in the indoor unit diagonally.
(c) Hang the panel on the two bolts and fix them temporarily.
(d) Tighten the bolts fixed temporarily and the ramaining two bolts.
Screw the remaining two bolts, and tighten all (four) bolts.
(e) Connect the louver motor connector (red) to the panel respectively.
(f) If the louver motor is not operated by remote control, check if the connector is connected correctly, and turn off the power for
more then 10 seconds, then reset it.
Panel Joint Setting
¡ The panel can turn 30 mm to the left and to the right in all, and the indoor
unit turns 30 mm to the left and to the right in all in the case of
FDT(N)258~508, and 20 mm in the case of FDT(N)208.
Limit Fixing Panel
1
Fix the panel only in the direction shown in the figure.
2
If it is fixed in other way, air will leak. Also, wires cannot be connected for
auto swing and receiver amp.
