Problem
Cause
Fix
Poor foam solution (wet or dry)
Using wetting agent in place of foam
Flush system and install Class “A” foam.
Lack of foam
Check if the Foam Pro system in on. Check if there
is foam in the reservoir. Make sure the foam supply
valve is on and the Y strainer clean. Reference the
Foam Pro instruction manual.
Incorrect size air lines to discharges
Refer to “Air Distribution Hose Size Guidelines”
in F-1031, Section 3027 (S100 Eclipse) or F-
1031, Section 3028 (CX Eclipse).
Foam in water system
Foam dumped into the water tank
Flush water tank and pump until foam is
cleared.
Foam cell is leaking into water tank
Condition applies to tanks utilizing a common
wall(s) between the foam tank and the water
tank. If a leak is confirmed, repair the foam tank
and flush the water tank and pump until foam is
cleared.
Foam proportioning manifold check valve mal-
function
If the above conditions have been corrected, the
final cause for foam in the water tank may be
the result of a malfunctioning foam manifold
check valve. To troubleshoot, cap off one foam
discharge that is plumbed to the foam manifold,
open that discharge valve and increase the
pump discharge to 30-40 PSI. Disengage the
pump and monitor the corresponding discharge
PSI gauge, looking for a drop in discharge pres-
sure. If the PSI drops, it indicates the foam man-
ifold check valve is leaking and requires repair.
Water in compressors oil/air
Leaking oil cooler
Isolate the heat exchanger and check for leaks.
Replace if necessary. (Typical cause is freez-
ing.)
Discharge air check valve(s) malfunctioning
Confirm direction (arrow towards discharge
valve). Replace if necessary.
Clutch smoking
Engaging compressor with the Electric Auto-
Sync in the FIXED or AUTO Mode.
Disengage compressor and place Electric Auto-
Sync settings to UNLOAD, allow the compres-
sor to bleed off, then engage the compressor.
High RPM engagement
Reduce engine RPM and engage in the
UNLOAD position with the Master Air Pressure
Gauge reading “0”.
Not allowing for compressor to bleed down prior
to re-engaging
Allow ample time for compressor to bleed down.
Re-engage the compressor in the AUTO and
UNLOAD settings.
Contaminated clutch disc or plate
Inspect the clutch disc and plate for contami-
nants (oil, dirt, foam, etc.). Clean or replace as
necessary.
Low air pressure or supply leak to clutch
Check pressure at supply side. Check supply
line for leaks.
Compressor locked up
Check entire system and repair as needed.
Air Regulator is Faulty
(P.T.O. Applications Only)
Replace Air Regulator
Safety pop-off valve opening at low
pressure
Sump fire damaged pop-off valve
Check the system and oil level. Replace the
pop-off valve. Once repaired, operate the com-
pressor watching for air or oil being discharged
from the pop-off valve. One indication of a pop-
off valve failure is oil present throughout the
pump compartment. Check for signs of sump
fire.
Compressor locked up
Debris in the compressor
Check entire system and repair as needed.
