Warnings
The following general warnings are for the setup, use, grounding, maintenance, and repair of this equipment. Addi-
tional, more specific warnings may be found throughout the body of this manual where applicable. Symbols appear-
ing in the body of the manual refer to these general warnings. When these symbols appear throughout the manual,
refer back to these pages for a description of the specific hazard.
WARNING
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent
fire and explosion:
• Use equipment only in well ventilated area.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop
cloths (potential static arc).
• Keep work area free of debris, including solvent, rags and gasoline.
• Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes
are present.
• Ground all equipment in the work area. See Grounding instructions.
• Use only grounded hoses.
• Hold gun firmly to side of grounded pail when triggering into pail.
• 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 fire extinguisher in the work area.
INTRINSIC SAFETY
Only models with a G3000 or G3000HR for both A and B meters are approved for installation in a Haz-
ardous Location - Class I, Div I, Group D, T2 C. To help prevent fire and explosion:
• Do not install equipment approved only for non-hazardous location in a hazardous area. See the ID
label for the intrinsic safety rating for your model. Refer to instruction manuals for your model.
• Do not substitute system components as this may impair intrinsic safety.
ELECTRIC SHOCK HAZARD
Improper grounding, setup, or usage of the system can cause electric shock.
• Turn off and disconnect power at main switch before disconnecting any cables and before servicing
equipment.
• Connect only to grounded power source.
• All electrical wiring must be done by a qualified electrician and comply with all local codes and regu-
lations.
SKIN INJECTION HAZARD
High-pressure fluid from gun, 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 gun at anyone or at any part of the body.
• Do not put your hand over the spray tip.
• 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.

Warnings
4311395A
EQUIPMENT MISUSE HAZARD

• 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 Graco
replacement parts only.
• Do not alter or modify equipment.
• Use equipment only for its intended purpose. Call your Graco 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.

Moving parts can pinch or amputate fingers and other body parts.
• Keep clear of moving parts.
• Do not operate equipment with protective guards or covers removed.
• Pressurized equipment can start without warning. Before checking, moving, or servicing equipment,
follow the Pressure Relief Procedure in this manual. Disconnect power or air supply.
TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or
swallowed.
• Read MSDS’s to know the specific hazards of the fluids you are using.
• Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.
PERSONAL PROTECTIVE EQUIPMENT

on ProMix™ Auto.
3. Shut off ProMix™ Auto power (0 position). FIG. 1.
4. If servicing EasyKey™ Display, also shut off power
at main circuit breaker.
After Servicing
After servicing the system, be sure to follow the
Start Up checklist and procedure in the ProMix™ Auto
Operation manual 311079.
Pressure Relief Procedure
1. While in Mix mode (dispensing mix material), isolate
the A and B fluid supply.
2. Push the manual override on the A and B dispense
valve solenoids to relieve pressure. FIG. 2.
3. Purge mix material following the Purging section in
the ProMix™ Auto Operation Manual (311079).
4. Isolate the solvent fluid supply.
5. Initiate purge sequence following the Purging sec-
tion in the ProMix™Auto Operation Manual
(311079).
6. Verify the solvent pressure is reduced to 0.
• To avoid electric shock, turn off EasyKey™ power
before servicing.
• Servicing EasyKey™ display exposes you to high
voltage. Shut off power at main circuit breaker
before opening enclosure.
• All electrical wiring must be done by a qualified
electrician and comply with all local codes and reg-
ulations.
• Do not substitute system components as this may
impair intrinsic safety.

Installation
See illustrations and “Parts” on page 10 for component
kit parts and referenced numbers throughout this proce-
dure.
Air Purge Valve Tee Installation
1. Remove (unscrew) the air purge valve (A) from the
inlet on the A side of the fluid manifold. See FIG. 3.
2. Install the tee (14) into the port that the air purge
valve was removed from. See FIG. 4.
3. Install the stainless steel check valve (19) into the
1/4” stainless steel street tee (14).
4. Attach the nylon coupled hose (15) to the check
valve (19) and route the hose (15) to the left side of
the panel where the third flush valve (1) will be
attached.
5. Reinstall the air purge valve (A) into the female port
of the tee (14).
Follow Pressure Relief Procedure on page 5 before
cleaning, checking, or servicing equipment. Read
warnings, page 3.
