
This equipment is for professional use only .

Read all instruction manuals, tags, and labels before you operate this equipment.
 Use the equipment only for its intended purpose. If you are not sure, call your Graco
representative.
 Do not alter or modify this equipment.
 Check equipment daily . Repair or replace worn or damaged parts immediately .


INJECTION HAZARD
Spray from the dispensing valve, leaks, or ruptured components can inject fluid into your body and
cause extremely serious injury , including the need for amputation. Fluid splashed in the eyes or on
the skin can also cause serious injury .

Fluid injected into the skin may look like just a cut, but it is a serious injury . Get immediate med -
ical attention.

Do not point the dispensing valve at anyone or at any part of the body .
 Do not put your hand or fingers over the end of the dispensing valve.
 Do not stop or deflect leaks with your hand, body , glove or rag.
 Use only extensions and no-drip tips which are designed for use with your dispensing valve.
 Do not use a low pressure flexible nozzle with this equipment.
 Follow the Pressure Relief Procedure on page 7 before you clean, check, or service the equip -
ment.
T
ighten all fluid connections before you operate the equipment.
 Check the hoses, tubes, and couplings daily . Replace worn or damaged parts immediately . Do
not repair high pressure couplings; you must replace the entire hose.

Operation
Never operate the meter with the black plastic cov -
er removed. The cover protects the meter from
damage due to impact. Meters are factory sealed
to keep moisture and dirt out. See the Service
section before you service the meter .
CAUTION
T o prevent line contamination, which can cause
equipment malfunction or damage, flush the lines
before you install this equipment in the system.
CAUTION
To Activate the Digital Display
Press the RESET key pad to clear the meter before
you start a new dispense cycle. This is the best way
to activate the meter , because it also clears the
quantity of the last dispense cycle.
Y ou can also activate the digital display by pressing
the TOT AL key pad or by running fluid through the me -
ter
. See Fig. 1.
NOTE: The digital display of the meter goes blank af -
ter approximately two minutes of non-use.
Function of TOTAL
When the digital display is blank, press and release the
TOTAL key pad to display the quantity of the last dis -
pense cycle. See Fig. 2.
T o see the accumulated total of fluid dispensed
through the meter , press and hold the TOT AL key pad.
The accumulated total is shown in gallons for the gal -
lon/quart/pint meter , and in liters for the liter meter .
The meter can accumulate a running total of up to
19999 gallons or liters dispensed before it returns to
zero. See Fig. 3.
Function of RESET
Press the RESET key pad to clear the quantity of the
last dispense cycle and return the digital display to all
zeros. See Fig. 1.
To Change the Measurement Units
(gallon/quart/pint meter only)
The meter is factory-set to dispense in quarts. T o
change the measurement units, press and hold the
RESET key pad until the measurement unit on the
right side of the digital display is flashing. Then press
the TOTAL key pad until the desired measurement unit
is shown. Release both key pads. See Fig. 4.
T o be sure the proper amount of fluid is dispensed,
always use the same measurement unit for a par -
ticular fluid.Units should be changed only by autho -
rized employees.
CAUTION
For Maximum Dispensing Accuracy
(gallon/quart/pint meter only)
Set the meter to dispense in pints or quarts when you
dispense 1 gallon or less.
Always press the RESET key pad to clear the meter
before a new dispense cycle.

WARNING
The electronically metered dispense valves have a
1500 psi (103 bar) Maximum Working Pressure.
The mechanically metered dispense valves have a
1000 psi (70 bar) Maximum Working Pressure.
Never exceed the maximum working pressure of
the valve you are using or of the lowest rated
component in your system, to reduce the risk of a
serious bodily injury , including fluid injection.
WARNING
T o reduce the risk of fluid injection, always grasp
the nozzle housing (B) from the threaded end, not
from the front, when you adjust the nozzle.
T o dispense from the non-drip nozzle, turn the knurled
sleeve clockwise until it is open. T rigger the valve.
When the dispense cycle is completed, release the
trigger and close the nozzle by screwing the knurled
sleeve fully counterclockwise.
Electronic Metered Valves
Press the RESET key pad on the meter to clear it be -
fore the next dispense cycle. See Fig. 1.
Mechanical Metered Valves
Turn the reset knob (C) counterclockwise back to the
zero stop. See Fig. 5. If the knob cannot be turned
easily , do not force it. Clean and inspect the meter as
explained on page 8.
CAUTION
Do not attempt to manually advance the mechani -
cal meter or force the reset knob past the zero
stop. Doing so will damage the meter ’ s gear
mechanism.

Troubleshooting
PRESSURIZED EQUIPMENT HAZARD
The equipment stays pressurized until
pressure is manually relieved. T o
reduce the risk of serious injury from
pressurized fluid, accidental spray from the
dispenser or splashing fluid, follow the Pressure
Relief Procedure whenever you:
 Are instructed to relieve pressure
 Stop dispensing
 Check, clean, or service any system equipment
 Install or clean fluid nozzles
WARNING Pressure Relief Procedure
1. Turn of f the power supply to the pump.
2. T rigger 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.
Electronic Meter
NOTE: Before you check or repair the meter , be sure all other valves, controls, and the pump are operating
properly.

Electronic Meter
To avoid damaging the electronic components of
the control:
Always use the personal grounding strap
provided with a replacement metering unit
and electronic control when you remove the
cover (1) and while you replace the parts.
This strap protects the electronic compo -
nents from damage due to electrostatic dis -
charge.

Do not lay anything on the control.
 Be sure the open side of the control faces up
if you lay it down.
 Do not twist or force parts. Align parts prop -
erly as instructed.
CAUTION
WARNING
T o reduce the risk of a fire, explosion, and serious
burns to the body , handle and dispose of a used
electronic control (103) properly .
The electronic control contains a lithium battery . Do
not short circuit, charge, force over discharge, dis -
assemble, crush, penetrate, incinerate or heat the
battery to a temperature above 185 F (85 C).
Any misuse or abuse of the battery may cause it to
leak or explode.
1. Relieve the pressure.
WARNING
T o reduce the risk of serious injury, when you are
instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 7.
2. Attach the disposable grounding wrist strap to your
wrist. Connect the adhesive-backed copper foil at
the other end to any convenient electrical ground,
such as the grounding screw or metal case of a
grounded electrical outlet.
3. Lift the bottom edge of the black cover (101) away
from the meter (102) and pull the cover of f.
Remove and discard the screws (106). Lift of f the
electronic control (103). Remove and discard the
large o-ring (104).
4.
Install a new metering unit (102) and/or electronic
control (103). Install the large o-ring (104) over the
lip on top of the metering unit (102). Align the
notch on the side of the electronic control (103)
with the notch on side of the metering unit (102).
Install the new screws (106) and torque them
oppositely and evenly to 4 to 6 in-lb (0.45 to 0.68
