1. Connect the power supply cord
2. Reset the circuit breaker when it’s
cooling after 5 minutes
After pressing the
START key, the
compressor
doesn't start but
the fan runs 1.The unit is in high pressure shut off
(Red alarm light turns on)
2.The unit is under low pressure
protection (Green light turns on)
1. Reduce the system pressure
2. The input loop is blocked, reset
after eliminating troubles
3. Check if well connected
4. Turn the

operation, such as output valves of
the unit or recovery cylinder are not
open
2.Thermal protector is disconnected,
but axial fan still running
3.The recovery cylinder is full at 80%
capacity
4. Recovery is over and the unit is
under low pressure switching point 1. Read carefully this operating
manual and follow the instructions,

1.The pressure inside the recovery
cylinder is too high
2.The compressor seals are worn out 1. Reduce the cylinder temperature
with the Recovery Cylinder Cooling
Method
2. Factory service is required
The unit
doesn't pull
out a vacuum
1.Connecting hoses are loose
