ECO Line Compressors Instruction Manual
Troubleshooting
Problem
Compressor does not
start.
Motor hum.
Compressor runs
continuously, but does
not fill the receiver.
Compressor does not
fill up to 8 bar.
Noise of air escaping
from the pressure
switch valve or the
dryer solenoid valve
when compressor is
not running.
Cause
• Mains power loss.
• Overvoltage or
undervoltage.
• Pressure switch has not
closed.
• Motor internal thermal
protector has tripped.
• Overload circuit breaker has
tripped (only for the
TOP
line).
• Capacitor discharged.
Faulty motor capacitor.
• Compressor is undersized
with respect to the air
demand of the dental
surgery or laboratory.
• Air leak in the system
tubing.
• Failure of a gasket or a
valve plate, or worn piston
rings.
• Solenoid valve burnt out (if
dryer present).
• Dirty non-return valve.
• One of the gaskets or valve
plates has failed.
Dirty non-return valve.
Solution
• Check the dental surgery or
laboratory circuit breaker.
• Measure mains voltage and
call the electrician if necessary.
• Connect pressure switch (See
Fig.
1
-
2
Page
5-02
).
• Allow the compressor to cool
down.
• Reset the thermal protector
(See
Fig.
3
on Page
5-04
).
• Replace the capacitor.
Replace the capacitor.
• Establish the compressed air
demand of the dental surgery
(approximately 60 l/min per
chair) or of the laboratory
and use a more powerful
compressor if necessary.
• Find and repair leaks.
• Change gasket or valve plate
or piston rings (See Pages
9-01
to
9-05
).
• Replace the solenoid valve
(If Dryer present).
• Discharge the receiver
pressure, unscrew the valve
and clean it (See Fig.
5
or
7
on
Page
2-02
).
• Replace the gasket or valve
plate (See pages
9-01
to
9-05
).
Discharge the receiver pressure,
unscrew the non-return valve
(See Fig.
5
or
7
on page
2-02
)
and clean it.
If the problem persists, replace
the valve.
