Overview
The Pump Fed Sanitizer is a spray applicator for applying chemical solutions, such as sanitizers in food processing facilities, to a variety of surfaces at 1.7
GPM @ 40 PSI. This unit receives ready-to-use chemical solution from a central chemical feed system and projects it through the hose, wand and fan nozzle.
Alternate flow rates are available upon request.

Safety & Operational Precautions
For proper performance do NOT modify, substitute nozzle, hose diameter
or length.
Manufacturer assumes no liability for the use or misuse of this unit.
Wear protective clothing, gloves and eye-wear when working with
chemicals.
Always direct the discharge away from people and electrical devices.
Follow the chemical manufacturer’s safe handling instructions.
Turn off solution supply when unit is not in use for extended periods.
TO INSTALL (REFER TO DIAGRAM, NEXT PAGE.)
1. Mount the unit to a suitable surface.
2. Connect the discharge hose as shown in the diagram and close the ball valve.
3. To prevent blocking the small jets flush any new plumbing of debris before connecting. And/or install a
strainer. (see options)
4. Connect pre-mixed solution supply line.
TO OPERATE
Always make sure the discharge ball valve is closed or pointed in a safe direction before turning inlet
valve on. Discharge valve can be shut off at any time during operation but should not be left off for
long periods of time with the inlet valve on.
1. With discharge wand in hand open the inlet ball valve. Then open the discharge ball valve to begin
application.
2. When sanitizing is completed, close the discharge ball valve then close the inlet ball valve.
3. Briefly re-open the discharge ball valve to relieve pressure in hose. If applicable rinse the work surface
before solution dries.

Troubleshooting Guide
AF 919155 • Pump Fed Sanitizer
Problem Possible Cause / Solution
Startup Maintenance
A) Weak pressure or will not spray 1, 2, 3, 4 5, 6
Possible Cause / Solution
Startup Maintenance
1. Inlet or discharge ball valves not completely open
Completely open both ball valves.
2. Solution pressure or volume too low/inlet piping too small.
Increase solution pressure or volume.
3. Discharge hose too long for available solution pressure, kinked or
wrong size
Straighten the hose or replace hose.
4. Nozzle size too small (SEE REQUIREMENTS)
5. Inlet orifice clogged
Check/clean inlet orifice for obstructions.
6. Hard water scale or chemical build-up may have formed in the body
causing poor or no flow
Follow Preventive Maintenance instructions below, using hot
water and/or de-scaling acid. When there is no flow at all,
carefully remove fittings and soak entire body in de-scaling acid.
PREVENTIVE MAINTENANCE: When the unit will be out of service for extended periods run water through the system to flush the
chemical and help prevent chemical build-up.
