Grounding
WARNING
FIRE, EXPLOSION, AND ELECTRIC
SHOCK HAZARD
Proper electrical grounding of your
system is essential. For your safety,
read the warning section, FIRE, EXPLO-
SION, OR ELECTRIC SHOCK HAZARD, on
page 4.
NOTE: Numbers in parenthesis in the text refer to the
reference numbers in the figures (Fig.) and in the parts
lists.
1. Follow the instructions in manual 308778 to ground
the Graco flow meter and check its electrical
grounding continuity.
2. Ground the Informer display by connecting the
ground wire (44 or 64) from the screw (35 or 54) to
a true earth ground. See Fig. 6.
3. Always ground the fluid supply unit, using one of
the following options:
a. Mount the meter to a grounded conductive
surface, or
b. Connect the conductive fluid hose to the meter
inlet and outlet, or
c. Connect a ground wire to the meter’s M6
mounting holes.
4. Never use the flow meter with an electrostatic gun
isolation stand.

Operation
Pressure Relief Procedure
WARNING
SKIN INJECTION HAZARD
The system pressure must be manually relieved to
prevent the system from starting or spraying acci-
dentally. Fluid under high pressure can be injected
through the skin and cause serious injury. To
reduce the risk of an injury from injection, splashing
fluid, or moving parts, follow the Pressure Relief
Procedure whenever you:
D are instructed to relieve the pressure,
D stop spraying,
D check or service any of the system equipment.
1. Turn off the fluid supply to the meter.
2. Shut off all electrical power to the fluid system.
3. Follow the Pressure Relief Procedure for your fluid
system dispensing device.
Flow Meter Operation
For information on Graco flow meter, part no. 239719,
see manual 308778. Calibrate the meter as instructed
on page 19 before using the meter for production.
WARNING
COMPONENT RUPTURE HAZARD
Do not exceed the maximum working pressure of
your meter or any component or accessory in your
system.
CAUTION
The flow meter gears and bearings can be damaged
if they rotate at too high a speed. To avoid high
speed rotation, open the fluid valve gradually. Do not
over-speed the gear with air or solvent. To prolong
meter life, do not use the meter above its maximum
flow rate.
