(Filter)
(Removing frost)
- Restart after operation stops when the discharge temperature exceeding 135°C is detected
- System down when two times of detection is made
(count is cleared when no detection is made for one hour)
- Shortage of refrigerant
- Compressor unloading defective (unloading failure)
- Service valve clogged
- Electronic expansion valve clogged
Error reset (Key 3)
Is both service valves open?
Since the service valve is clogged, open
the service valve.
Since it is the electronic expansion valve
close error, check the electronic expansion
valve and PCB related.
Since the refrigerant is insufficient,
check to charge if needed.
Is the low pressure
rapidly dropping and the
discharge temperature
increasing?
Since it is the defect of compressor
unloading, check the coil end of PWM
valve. If there is no trouble in the coil,
replace the PWM valve.
Test operation (key 4)
The system check is completed.
Are all indoor units
operated normally?
Is high pressure and
low pressure normal?
Is all the above check
items normal?
Complete the test operation mode
and check for 1
