Poor spray pattern.
Also, see “System runs erratically” below.
Fluid pressure too low.
Increase metering pump pressure.
Fluid temperature too low.
Increase fluid temperature.
Spray tip dirty or worn.
Relieve pressure. Clean or replace tip.
Follow gun manual instructions.
Mix manifold, mixer, swivel, gun, or hoses
partially plugged or too restrictive.
Inspect parts for cured material. Clean or
replace, or use larger hoses and mixer.
System runs erratically.
Air filter(s) clogged.
Clean. Replace element(s).
Air supply hoses undersized.
Replace hoses with appropriate size.
Air compressor undersized.
Use larger air compressor.
Air supply pressure tank undersized.
Use larger pressure tank.
Inlet air pressure gauge drops below 50
psi (0.35 MPa, 3.5 bar) while spraying.
See solutions above for system runs
erratically problem.
A and/or B air motor has ice.
Open air motor de-ice bleed air control.
Allow ice to melt. Dry the compressed air.
Heat the compressed air. Use a smaller
tip and lower flow rate.
Metering pump is binding.
Repair lower. See XM PFP repair man-
ual.
Air supply relief valve opens.
Air regulator set too high.
Lower setting.
Flow rate too low.
Air supply hose is too small or too long.
Use 3/4 in. minimum ID air supply hose.
See
, page 98.
Inadequate air supply.
Use larger CFM compressor.
Air pressure to metering pumps too low.
Increase metering pump air pressure.
Spray tip too small.
Relieve pressure. Install larger tip. Follow
gun manual instructions.
Mix manifold, mixer, swivel, gun, or hoses
partially plugged or too restrictive.
Inspect parts for cured material. Clean or
replace, or use larger hoses and mixer.
Receive ratio alarm after starting in spray
mode while using remote mix manifold.
A and B hoses do not fill to correct pres-
sure ratio simultaneously. Therefore,
spray time increases in order to balance
pressure. Ratio screen bar graph stays to
one side until pressure balances.
Pressurize outlet hoses in manual A/B
pump mode. Then start spray mode.
Select correct hose size to balance your
volume ratio. See XM PFP Mix Manifold
manual.
Receive ratio alarm while using remote
mix manifold after a significant change in
pressure.
A and B hoses do not fill to correct pres-
sure ratio simultaneously. Therefore,
spray time increases in order to balance
pressure. Ratio screen bar graph stays to
one side until pressure balances.
Pressurize outlet hoses in manual A/B
pump mode. Then start spray mode.
Select correct hose size to balance your
volume ratio. See XM PFP Mix Manifold
manual.
Change pressure slowly while spraying.
