INSTALLATION 8 Installation details 8.1 Select the best location. 1. To avoid vibration and noise, make sure the unit is installed securely and firmly. 2. Install the unit where the sunlight does not shine directly on the unit. If the unit receives. direct sunlight, build an awning to shade the cabinet.
INSTALLATIOIN 8.2 Check off installation. The setting conditions must be checked prior to initial starting. The under mentioned items are especially important checking points when the installation is finished. Grounding wire (yellow/Green) is provided in the power cord. The wire must be grounded. Ensure that the unit is connected to a suitably rated and dedicated circuit.
INSTALLATION 8.4 How to install. 1) Remove the sticker from the front panel. 2) Put the unit into the installation hole. When installing the unit, it should be slanted down to the back to avoid the enlargement of noise or vibration.(Slant between 6-10mm.) The installation place should be strong enough to avoid the enlargement of noise...
TROUBLESHOOTING 11 Troubleshooting In general, possible trouble is classified in three kinds. One is called Starting Failure which is caused from an electrical defect, another is ineffective Air Conditioning caused by a defect in the refrigeration circuit and improper application, and the other is called the Structure Damage. Operation panel don't work.
Page 23
TROUBLESHOOTING The air-con doesn't work. Check the power supply. Check the wiring. Check whether the transformer is failed. Measure the output voltage of transformer and check whether it is the range from +5V to 12V. If not, replace the transformer. Replace the PCB.
Page 24
TROUBLESHOOTING Display keeps showing "Ed". Check whether the evaporator frosts. Check whether the indoor air inlet is blocked. Check whether the indoor ambient temperature is too low. Check whether the indoor dust filter is too dirty. Check whether there is too much water on the chassis. Check the wiring of pipe temperature sensor.
Page 25
TROUBLESHOOTING Compressor doesn't work. Check whether the indoor temperature is lower than 15° C or larger than 31° C. Check the power supply. Check whether the voltage is too high or too low. Check the wiring. Check whether the compressor is under overload protection. Check the relay of compressor in PCB works normally.
Page 26
TROUBLESHOOTING Cooling mode don't work or cooling not enough. Check the operation mode. Check the setting temperature. Check whether dust filter is too dirty. Start the unit with cooling mode, check whether the temperature of the compressor's discharge pipe is smaller than 90 ℃ , if no, recharge refrigerant. Replace the capillary.
Page 27
TROUBLESHOOTING The compressor operates run-stop frequently. Check whether the airflow passage is blocked. Check whether the fan motor doesn't work. Check whether capacitor of compressor work normally. Check whether the relay of compressor on PCB works normally. Replace the PCB. Check whether the capillary is blocked.
