Notes: 1) Water alert filters are for use with gasoline, ether-blended fuels, and diesel fuel.
They are not for use with alcohol-blended fuels.
2) Alcohol monitor filters are for use with ethanol-blended fuels containing up to 20%

Servicing Filters
This section explains about servicing the filters.
Before Removing Filters
Before removing the filters, proceed as follows:
1
Use OSHA lockout/tagout procedures.
2
Close the shear valve (dispensers only). Refer to
on
operation of the valve. Multiple shear valve closures may be required. Shut off all power to
pumps.
3
Bleed pressure (dispensers only):
a. Lift the operating handle and authorize the unit.
b. Place the nozzle in the approved container.
c. Close the nozzle.
d. Shut off the operating handle.
4
Shut off the associated STP circuit breakers (dispensers only). Multiple STP disconnects may
be required.
5
Shut off the dispenser circuit breaker.
6
Shut off all power to the unit.
Removing Filters
WARNING
Servicing filters without shutting off power properly and ensuring that the appropriate
valves are closed may result in fuel discharge or spray. Any involved STPs with power still
applied can be energized from another unit resulting in fuel pressure in the product lines
for the unit you are working on. Pumping units with power applied could also be accidently
energized. Commonly, retightening of the filter under pressure will not stop fuel flow as the
seal can be blown out of the sealing position during tightening.
Fire and explosion could result in severe injury or death.
Ensure the following:
• Wear eye protection
• Test and close the involved shear valves
• Shut off power to the pump, dispensers, and any involved STPs
• Remove the parts slowly. Collect fuel in approved containers.
• Clean up all spills promptly
Use an approved container to collect the residual fuel. Use gasoline/fuel-approved absorbent
materials to mop up the spilled fuel. Use Gasboy-approved fuel collectors, if applicable. Be
careful of any residual fuel. Always follow all safety warnings and cautions.
