Maintenance; Residue Build-Up On The Meter Gears; Flushing - Graco G3000 Instructions-Parts List Manual

Maintenance

Maintenance
Improper wiring can cause fire and explosion, electric
shock, or other serious injury.
• Disconnect power source before installing.
• All electrical equipment must only be installed by
a qualified electrician.
• Understand and follow your local code and safety
regulations for hazardous location wiring of intrin-
sically safe circuits.
NOTICE
Do not immerse the meter in solvent with the elec-
tronic sensor installed. Solvent could damage the
electrical components.
Air purge is not recommended for any gear-type flow
meter. Air purges do not provide the lubrication the
meter gears require.
Residue Build-up on the Meter
Gears
Residue build-up may cause the meter gears to bind or
stop rotating, which decreases the meter accuracy and
makes meter recalibration necessary. As more build-up
occurs, recalibration is required more often.
The frequency that your meter requires cleaning
depends on the type of fluid being used. Excessive resi-
due build-up usually means that you are using improper
cleaning solvents and/or cleaning sequences or pro-
cesses.
• Check the meter routinely to develop the correct
cleaning schedule.
• Use the proper cleaning solvent for the fluid being
metered.
