NOTE: Contact FBD Customer Service at
866-323-2777 for questions concerning
compressors and operational issues.
NOTE:
H2O readout will be 15-20
psi higher on the readouts.
Keep regulated pressure at
70-72 psig.

psig, adjust regulators, if necessary.
C. Run capacitor problem. C. Test run capacitor. Replace, if
necessary.
D. Contactor failure. D. 1. In Manual On/Off, activate
“Compressor.” DO NOT RUN
COMPRESSOR FOR MORE

If contactor energizes, quickly
check voltage across contactor
T1 and T2 for 220 volt. If no
voltage reading, replace
contactor. “
2. In Manual On/Off, activate
“Compressor.” DO NOT RUN
COMPRESSOR FOR MORE
THAN 10 SECONDS!
If contactor does not energize,
quickly check voltage across
contactor coil terminals for
24VAC. If voltage is present,
replace contactor.
E. Relay board not sending E. Test relay board for 24VAC output
power to contactor coil. and 5VDC input on contactor relay.
Replace relay board, if necessary.
