Error with the electromagnetic
valve or drainage valve
Suction line is disconnected
Check the solenoid valve and
supply lines

leaks and tighten if necessary
CONDITION
(ERROR)
POSSIBLE CAUSES
SOLUTION

Change the O-rings of the trap
Change the oil
Remove obstruction in pipe
Fix leak. Replace pipe if required
Oil overheated to above 97
С
Ensure the adequate ventilation of
the space and proper air intake

Control line drainage / control
valve interrupted
Check the activation of the
drainage valve at maximum
pressure.
Contact the seller / manufacturer
The compressor switches to
idle before reaching the
maximum
pressure
or
restarts, before the pressure
decreases
Wrong set point for maximum
pressure.
Adjust regulator
Pressure sensor error
Contact the seller / manufacturer.
Performing continuity checks
with the sensor is prohibited
Motor
squeal
during
operation
Belt slippage due to insufficient
voltage or dirt on the belt /
pulley
Clean the belt / pulley and adjust
the tension properly

compressor, a hiss can be
heard.
Slow
pressure
reduction
Minimum pressure valve error
Replace the valve.
The valve must not be adjusted
Air is escaping from the
drainage / safety valve
Drainage / safety valve error
Replace valve
Incorrect pressure settings
Maximum pressure must comply
with the user's manual
(Contact manufacturer)
