Acson international E Serie Manuel D'installation page 20

NOTE
• Avoid using the short duct on which the air discharge grille can be completely closed, to prevent evaporator freezing.
• In order to prevent condensation forming, be sure that there is sufficient thermal insulation and no leakage of cool
air when installing the short duct.
• Keep the introduction of fresh air intake within 20% of total air flow. Also provide a chamber and use a booster fan.
Sealing Material
• It is possible to seal one of the four air discharge outlet. (sealing two or more air discharge outlet could cause a malfunction)
• Remove the front panel and insert the sealing material into the air discharge outlet on the indoor unit to seal the air outlet.
• The sealing material is the same length as the longer air discharge outlet. If it is desired to seal the shorter air discharge
outlet, cut the sealing material to shorten it.
• Push the sealing material in about 10 mm beyond the bottom surface of the indoor unit so that it does not touch the air
louver. Be sure not to push the sealing material in any farther than about 10mm.
Remote Control
When there is infrared remote control operating signal, the signal receiver on indoor unit will made a <beep> for signal
acceptance confirmation.
Event
1. Room Sensor Open or Short
2. Indoor Coil Sensor Open
3. Outdoor Coil Sensor Open
Compressor Overload /
4. Indoor Coil Sensor Short /
Outdoor Coil Sensor Short
5. Gas Leak
6. Water Pump Fault
7. Outdoor Defrost
8. Outdoor Coil Sensor Exist (MS model)
9. Hardware Error (tact switch pin short)
NOTE
CDF LED = Cool/Dry/Fan LED, turns on in these modes
The unit will not detect sensor missing when the compressor is ON
Call your dealer immediately when this error happen
• After installation of the unit, ensure that :-
1. The unit has been mounted solidly and rigid in position.
2. Outdoor unit is fully installed
3. Gas leak test is been checked.
4. Unit is fully insulated.
5. The drainage is flow smoothly - pour some water into the main drain pipe from the flexible drain hose.
6. The power supply, voltage correspond to that unit shown on wiring diagram are attached on the unit.
7. Wiring and piping install correctly and firmly.
8. Unit is safely grounded.
9. Wiring size is according to specification.
10. Air inlet and outlet are not blocked.
11. Note down the refrigerant piping length and additional refrigerant charge.
• Test run
1. Conduct a test run after water drainage test and gas leakage test.
2. Check the following items :-
a. Is the electric plug firmly inserted into the socket ?
b. Is there any abnormal sound from the unit ?
c. Is there any abnormal vibration on the unit itself or piping ?
d. Is the drainage of water smooth ?
• Confirm that :
1. Condenser fan is running, with warm air blowing off the condensing unit.
2. Evaporator blower is running and discharge cool air.
3. The remote control incorporate a 3 minute delay in the circuit. Thus, it requires about 3 minutes before the outdoor
condensing unit can start up.
