Warnings

Warnings

The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama­tion point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. Refer back
to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where
applicable.

WARNING

SKIN INJECTION HAZARD

High-pressure fluid from dispense valve, hose leaks, or ruptured components will pierce skin. This may
look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical

treatment.

• Do not point dispense valve at anyone or at any part of the body.

• Do not put your hand over the end of the dispense nozzle.

• Do not stop or deflect leaks with your hand, body, glove, or rag.

• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning,
checking, or servicing equipment.

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

• Do not operate the unit when fatigued or under the influence of drugs or alcohol.

• Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component. See Technical Data in all equipment manuals.

• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all
equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information
about your material, request MSDS forms from distributor or retailer.

• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manu­facturer’s replacement parts only.

• Do not alter or modify equipment.

• Use equipment only for its intended purpose. Call your distributor for information.

• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.

• Do not kink or over bend hoses or use hoses to pull equipment.

• Keep children and animals away from work area.

• Comply with all applicable safety regulations.

FIRE AND EXPLOSION HAZARD

When flammable fluids are present in the work area, such as gasoline and windshield wiper fluid, be
aware that flammable fumes can ignite or explode. To help prevent fire and explosion:

• Use equipment only in well ventilated area.

• Eliminate all ignition sources, such as cigarettes and portable electric lamps.

• Keep work area free of debris, including rags and spilled or open containers of solvent and gasoline.

• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.

• Ground all equipment in the work area.

• Use only grounded hoses.

• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment
until you identify and correct the problem.

• Keep a working fire extinguisher in the work area.

Typical Installations

FIG. 1 shows a typical hose reel installation. Dispense
valves can also be installed on a console as shown in
Fig. 2.

The typical installation shown in Fig. 1 is only a guide. It
is not a complete system design. Contact your Graco
distributor for assistance in designing a system to suit
your needs.

KEY DESCRIPTION

A Metered dispense valve
B Fluid shut–off valve
CHose
D Hose reel fluid inlet hose
E Hose reel
A Thermal Relief Kit (not shown) is required. The kit
will vary by pump selected. See Parts, page 28 for a
list of available kits.

NOTICE

• Do not use this dispense valve on non-Graco con­soles. The trigger could be inadvertently pressed
while the dispense valve is stowed.

• This dispense valve is not designed for in-line
installation. Do not install with a shut-off valve on
the outlet side of the meter which could damage
the meter housing cover.

Mounting Bracket

Mounting bracket 196471 is available for resting dis­pense valve on a console. See Fig. 2.

NOTICE

Do not obstruct the dispense valve trigger and do not
set the unit down resting on its trigger or it might not
stop dispensing.

Pressure Relief Procedure

The equipment stays pressurized until pressure is man­ually relieved. To reduce the risk of serious injury from
pressurized fluid, accidental spray from the dispense
valve, or splashing fluid, follow this Pressure Relief
Procedure when you:

• are instructed to relieve pressure.

• check, clean, or service any system equipment.

• install or clean fluid nozzles or filter.

1. Turn off the power supply to the pump.

2. Trigger the dispense 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 are ready to
pressurize the system.

Grounding

Pre–Installation Procedure

1. Install the battery. See Replacing the Battery on
page 31.

2. Follow the Pressure Relief Procedure.

3. Close the shut–off valve (B, F

4. Ground the hose and reel or console. See
Grounding.

Leave a minimum of two engaged threads bare
when using PTFE tape. The bare threads ensure a
ground is maintained.

IG. 1, page 5).

Installation Procedure

NOTICE

If this is a new installation or if there is contaminated
fluid in the lines, flush the lines before you install the
metered valve. Contaminated lines could cause the
valve to leak.

If this is an existing installation, go to step 7. Steps 1 - 6
are the Flushing Procedure.

Proper grounding is an essential part of maintaining a
safe system. The movement of fluids through the dis­pensing system generates static electricity. Static elec­tricity can cause fumes to ignite, resulting in explosion
and fire. To reduce the risk of static sparking, ground all
system components per local and national electrical
codes. Refer to user manuals for pump and other sys­tem components to ground the following:

• Pump: Follow manufacturer’s recommenda-

tions.

• Air and Fluid hoses: Use only grounded

hoses.

• Air compressor: Follow the manufacturer’s

recommendations.

• Fluid supply container: Follow the local code.

To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of valve

firmly to side of grounded metal pail, then trigger valve.

a. Place the hose end (with no dispense valve

connected) into a container for waste oil.

b. Secure the hose in the container so it will not

come out during flushing.

c. If you have multiple dispense positions, first

flush the dispense position farthest from the
pump, then work your way toward the pump.

Kits: 257350 and 257351

NOTICE

It is important to properly seat gasket (2) when install­ing electronic control (1) to fluid section. An improp­erly seated gasket could cause the meter to report
invalid dispense amounts because the glass reed
switches are broken.

Operation, (LDM5 Meters - page 13; LDP5 Meters ­page 22), for proper operation of meter.

IG.

2. Thread extension into meter outlet at least three full
turns to tighten securely. (F

IG. 7). (Over torquing

may cause casting meter to split)

NOTICE

• Do not overtighten extension to sealing nut. Over
tightening may cause meter casting to split.

• Do not use a twist/lock or manual shut-off nozzle.
You must use an automatic nozzle on the meter or
the meter could be damaged.

3. Thread new nozzle (26b) onto extension. With an
open-end, adjustable wrench.Tighten it firmly.

Only tighten nozzle with the wrench on the flats of
the nozzle bushing. Do not disassemble the
bushing from the nozzle. Disassembly will affect
the performance of the nozzle.

• To ensure dispensing accuracy, purge all air
from the fluid lines and dispense valve before
you use it.

• Set the system flow to the desired flow rate,
which is typically 1.5 gpm. Do not exceed a
5-gpm flow rate.
