Test operation■ Check the stop valvesMake sure to open the gas and liquid line stop valves.■ After installation, perform the test operation.Unless the test operation is performed, the error code "U3" isshown on the remote controller and the unit cannot be operated.Performing the test operation1 To protect the compressor, make sure to turn on the powersupply 6 hours before starting operation.2 Set to setting mode 1 (H1P led is off) (refer to "Setting mode 1"on page 18).3 Press the button for 5 seconds when the unit is at astandstill. The test operation starts when the H2P led blinks andthe remote controller indicates (test operation) and(external control).It may take 10 minutes to bring the state of refrigerant uniformbefore the compressor starts, but that is not a malfunction.The test operation is automatically carried out in cooling modeduring 15~30 minutes.Depending on the situation, the refrigerant running sound or thesound of a magnetic solenoid valve may rise during thisoperation.The following items are automatically checked:- Check for incorrect wiring- Check if stop valves are open- Check of refrigerant charge- Automatic judgement of piping length4 After the test operation (maximum 30 minutes), the unitautomatically stops.
