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 you local code and safety
regulations for hazardous location wiring of
intrinsically safe circuits.
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
residue build-up usually means that you are using
improper cleaning solvents and/or cleaning sequences
or processes.
•
Check the meter routinely to develop the correct
cleaning schedule.
•
Use the proper cleaning solvent for the fluid being
metered.

NOTICE
Flush the Equipment
To avoid fire and explosion, always ground equipment
and waste container. To avoid static sparking and
injury from splashing, always flush at the lowest
possible pressure.
Flush the fluid supply line and meter fluid reservoir daily
with a compatible solvent as instructed below.
1. Perform the Pressure Relief Procedure, page 10.
2. Connect the fluid line to the solvent supply unit.
3. Flush the meter until it is clean.
4. Perform the Pressure Relief Procedure, page 10,
then disconnect the fluid line from the solvent supply
unit.
5. Reconnect the fluid line to the fluid (paint) supply.
6. Turn on the fluid supply.
7. Operate until the meter and fluid line are free of
solvent.
