Troubleshooting
1. Relieve the pressure before you check or service any sys-
tem equipment.
2. Check all possible causes and solutions in the trouble-
shooting chart before disassembling the manifold.
Problem Cause Solution
Little or no resin output. Fluid inlet is plugged. Clean inlet; remove obstruction.
Fluid container is empty. Refill.
Little or no hardener output. Fluid inlet is plugged. Clean inlet; remove obstruction.
Fluid container is empty. Refill.
Hardener screen (18) is plugged. Clean hardener screen. See Clean “B”
Side Screen, page 17.
Mixed fluid will not flush out. Fluid is hardened in static mixers or whip
hose.
Clean with compatible solvent. See Main-
tenance, page 17. Replace as neces-
sary.
Solvent supply container is empty. Refill.
Solvent is not compatible with fluid. Change to compatible solvent.
Hardener pressure higher than normal. Hardener is cold. Correct heat problem.
Restrictor or screen plugging up. Open restrictor or clean screen. See
Clean “B” Side Screen, page 17.
Hardener pressure lower than normal. Resin is cold. Flow rate is low. Correct heat problem.
Worn hardener restrictor. Adjust restrictor. See Adjust Restriction
at the Mix Manifold, page 15.
Spray pattern developing tails. Static mixer and/or whip hose plugging
up.
Clean Static Mixers, page 17.
Clean spray gun and tip. See gun man-
ual.
Low pressure from sprayer. Check air supply pressure. Check inlet air
gauges while spraying.
Cold material. Increase heat.
Too much pressure drop. Use larger hoses or more heat.
Not enough air supply. Gauge drops
while spraying.
Air hose is too small.
Compressor is too small.
Motor is icing. Use De-Ice Bleed Air on motor. Dry or
cool air before use.
Wait for motor to thaw.
Dirty filter in pumps or spray gun. Clean filters.
Resin or hardener does not shut off. Damaged ball or seat or seal in valve
(20).
Replace or rebuild valve (2). See manual
306861.
Off ratio condition after increasing spray
pressure in spray mode with a remote mix
manifold.
Hoses not volume balanced. Volume balance A and B remote material
hoses closer to volume mix ratio. See
Hose Selection for Feeding A Remote

nance, page 17.
