If air remains in the refrigeration piping, it will affect the compressor, reduce the cooling capacity, and could lead to a malfunction of unit. Be sure, using a torque wrench to tighten the service port cap (after using the service port), so that it prevents the gas leakage from the refrigeration cycle. Procedure 1. Open the valve stem of the 2-way valve counterclockwise approximately 90', wait 10 seconds, and then set it to closed position. Set the 2-way valve to the open position and remove the cap from the 3-way valve's service port. Using the hexagonal wrench to press the valve core pin, discharge for three seconds and then wait for one minute. Use torque wrench to tighten the service port cap to a torque of 18n. m 6. At this time, especially check for gas leakage from the 2-way and 3-way stem nuts, and from the service port. Caution: If gas leakage is discovered in step (3) above, take the following measures. 10. 2. 4 Inverter module Protection, Inverter module Protection itself has a protection function against current, voltage and temperature. 10. 2. 5 Sensor protection at open circuit and breaking disconnection 10. 2. 6 Fan Speed is out of control. When Indoor Fan Speed is too high(higher than 2100RPM)or too low(lower than 300RPM), the unit stops and LED displays failure information and can't return to normal operation automatically. If there is no Cross Zero signal in 4 minutes, the unit stops and LED displays failure information and can't return to normal operation automatically. 9. 3 Fan-only mode The compressor4-way valve and outdoor fan is off at fan-only mode.
