Indoor Unit Fixing • • • • Thread the indoor unit piping and cable through the hole. Hang the top of the unit onto the upper ridge of them in mounting plate. Make sure that the unit is correctly hung in place by sliding it to the left, then to the right. Press the bottom left and bottom right hand corners of the unit against the mounting plate until the fixing prongs click into place in the retainers provided to that effect.
To this effect, when the piping has been evacuated, close the pressure gauge tap, note the value on the gauge, then wait for 15 minutes. If the needle moves, there is a leak in the system. Make the necessary adjustments or repairs and repeat this procedure until the needle no longer moves. - Open the service valves and top up the refrigerant charge if necessary.
Wiring Prepare the power source for exclusive with the air conditioner. The supply voltage must comply with the rated voltage of the air conditioner: The plug socket shall be accessible after installation. Remark: All the wiring must be based on the wiring nameplate which shown on the model. CAUTIONS • Perform the wiring with sufficient capacity. Installation places legally require a short circuit isolator to be attached to prevent electrical shock. • Do not extend the power cable code by cutting.

Then wipe it with a dry cloth.
OPERATION TIPS The following events may occur during normal operation. 1. Protection of the air conditioner. Compressor protection • The compressor cannot restart for 3 minutes after it stops. Anti-cold air (Cooling and heating models only) • The unit is designed not to blow cold air on HEAT mode, when the indoor heat exchanger is in one of the following three situations and the set temperature has not been reached. A) When heating has just starting. B) Defrosting. C) Low temperature heating.
TROUBLESHOOTING GUIDE Problem A. The air conditioner does not run. Probable cause 1. Power Failure. 2. Fuse blown or circuit breaker open. 3. Voltage is too low. 4. Faulty contactor or relay. 5. Electrical connections loose. 6. Thermostat adjustment too low (in heating mode) or too high (in cooling mode) 7. Faulty Capacitor 8. Incorrect wiring, terminal loose 9. Pressure switch tripped B. The outdoor fan runs but the compressor will not start. 1. Motor winding cut or grounded. 2. Faulty Capacitor. C.
