Possible Cause / Solution
Startup
Maintenance
1. Air line too small, not enough air pressure or volume
See REQUIREMENTS, page 1.
2. Air pressure too high.
Slightly close the air supply valve to lower the pressure
by lowering the volume until the fogger smooths out.
3. Fogger too high to draw chemical, 12' maximum
Raise the level of the chemical
4. Chemical tube kinked or not immersed in chemical or
chemical depleted.
Straighten tube / replenish chemical
5. Drawing too much solution
Order and install optional metering tip or needle valve (4
& 8 Way only).
6. Timer failed
Replace timer.
7. May have electrical problems
Ensure circuit breaker (5 Amp) has not been tripped.
Have a qualified electrician check electrical connections.
8. Pin hole or cut in suction tube
Replace suction tube.
9. Chemical strainer clogged up
Clean or replace
10. Metering tip or metering tip holder clogged
Clean or replace metering tip and/or metering tip holder.
11. Debris clogging the fogger inlet jets
Disconnect air supply, remove fogger bodies and
visually inspect; remove debris from fogger inlet.
PREVENTIVE MAINTENANCE: When the unit will be out of service for extended periods, place chemical tube(s) in water and flush the chemical out
of the unit to help prevent chemical from drying out and causing build-up. Periodically check and clean chemical strainer and replace if missing.
