TROUBLESHOOTING CHART
Problem Possible Cause(s) Possible Solution(s)
1. Motor/compressor does not start a. No electric power a. Check circuit breaker at main power source
b. Power not connected b. Check 24 volt remote connections
c. Defective power switch c. Power switch needs to be replaced. Call your
authorized dealer for service. Check compres-
sor power switches are in the ON position
d. Fuse is blown/damaged d. Check fuse in electrical enclosure
2. Motor tries to start, circuit
breaker trips
a. Voltage too low. If each compressor head
runs separately, but not together, the volt-
age is too low
a. Compressor requires a minimum of 208 volts.
If the voltage is too below required minimum, a
buck-boost transformer must be installed
b. Solenoid valve does not open when com-
pression cycle ends
b. Check the solenoid valve. If it does not open at
the end of the cycle, call authorized dealer for
service
c. Pinched drain tubing from solenoid valve c. Remove kink/pinch in drain line and verify proper
operation
d. Power supply cable too small d. See SITE REQUIREMENTS
e. Loose electrical connection e. Call authorize dealer for service
3. Unusual or excessive noise a. Intake filter(s) not seated correctly a. Remove filter(s) and replace if clogged or dirty.
When installing, make sure filter chamber is
clean and filter is sealed properly.
b. Intake filter(s) clogged or dirty b. Replace filters
c. Motor or compressor noise c. Call authorized dealer for service
d. Air leaks d. Close the air outlet valve. Check all fittings for
leaks. If leak is found, call authorized dealer for
service.
e. Check cooling fans e. If fan is loose or broken, call authorized dealer for
service.
4. Compressor cycles but does
not buid up pressure to 100 psi
a. Solenoid valve does not close or leaks
when compressor runs
a. Check the solenoid valve. Call authorized dealer
for service.
b. Clogged or dirty intake filters b. Replace intake filters
c. Leak in compressor system c. Close the air outlet valve. Check all fittings for
leaks. If leak is found, call authorized dealer for
service. (See “Testing Compressor for Leaks” in
MAINTENANCE section.)
d. Pressure switch needs adjusting d. Disconnect main power supply. Drain air tank
slowly until you hear a “click”. Air tank should
read approx. 80 PSI on the system pressure
gauge. Close the air outlet valve, turn on the
power switch and verify the pump-up time for
your model. Call authorized dealer for service
(see “System Checks and Tests” for pump up
and recovery times.)
e. Leak in the ofce air system e. With the power switch ON, ensure the compres-
sors are running. Close the air outlet valve and
wait for the compressor system to shut off at
100 psi. Wait 5 minutes and open the air outlet
valve. If the pressure drops (by more than 5 psi
or the compressors start again) the leak is in
the office air lines or delivery units. Contact your
authorized dealer for service
