Installation
Installation
These meters must be installed in-line as part of a dispense system as shown in Fig. The typical installation shown is
only a guide for selecting and installing an in-line meter. It is not an actual system design. Contact your Graco repre-

Operation
To Verify the Accuracy of an
Electronic Meter
1. Use a clean, calibrated container. If using a single
container, be sure to clean it after each dispense.
2. Have pump air pressure at the lowest possible set-
ting for dispensing fluid.
3. Put the tip of the nozzle at the bottom of the cali-
brated container.
4. If the tip of the dispense valve does not reach the
bottom of the calibrated container, use a length of
plastic tubing over the tip of the nozzle to ensure liq-
uid enters the container from the bottom.
5. Trigger the gun slowly so the fluid immediately cov-
ers the tip of the dispense valve.
6. Allow product to sit for 20 minutes, then compare
the actual, physical measurement in the calibrated
container to the measure displayed on the meter.
NOTE: The procedure above will determine if the meter
is accurately dispensing the product and minimize test-
ing errors. Some variance may occur depending on the
viscosity of the fluid. If this procedure determines that
the meter is not accurate replace the meter or the elec-
tronics as necessary.
For Maximum Dispensing
Accuracy
(gallon/quart/pint meter only)
Set the meter to dispense in pints or quarts when dis-
pensing 1 gallon or less.
Always press the RESET key pad to clear the meter
before a new dispense cycle.

Troubleshooting
Troubleshooting
NOTE: Before you check or repair the meter, be sure all
other valves, controls, and the pump are operating prop-
erly.
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury
from pressurized fluid, such as skin injection,
splashing fluid and moving parts, follow the Pressure
Relief Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.
1. Turn off the power supply to the pump.
2. Trigger the valve into a waste container to relieve
pressure.
3. Open any bleed-type master air valves and fluid
drain valves in the system.
4. Leave the drain valve open until you have com-
pleted repairs and are ready to pressurize the sys-
tem.
