4.4 Maintenance of Major Components

4.4.1 Replacement of thermostat
Please refer to the instruction manual of thermostat XE70-00/E1.
4.4.2 How to replace the compressor
4.4.2.1 Diagnosis of compressor failure
A. On condition that the unit can be started up
Step 1:
If the unit can be started up, then start it up to check the current of the faulted compressor. Use a pressure
gauge to measure the pressure of the big and small valves. Connect with a computer to monitor the data. Refer
to the following table based on the recommended working current. The electric current of an inverter compressor
will be different under different rotation speed or different working conditions. If the compressor is working at
60Hz, the working current corresponding to different condensing temperature and evaporating temperature is
shown below:
