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 symbols refer to procedure-speci c

risks. When these symbols appear in the body of this manual or on warning labels, refer back to these

Warnings. Product-speci c hazard symbols and warnings not covered in this section may appear throughout

the body of this manual where applicable.

WARNING

ELECTRIC SHOCK HAZARD

This equipment must be grounded. Improper grounding, setup, or usage of the system can

cause electric shock.

• Turn off and remove power before disconnecting any cables and before servicing or installing

equipment. For cart-mounted models, unplug the power cord. For all other units, disconnect

power at the main switch.

• Connect only to grounded power source.

• All electrical wiring must be done by a quali ed electrician and comply with all local codes

and regulations.

• Wait ve minutes for capacitor discharge before opening equipment.

• For cart-mounted models, use only 3-wire extension cords.

• For cart-mounted models, ensure ground prongs are intact on any power and extension cords.

• For cart-mounted models, do not expose to rain. Store indoors.

FIRE A D EXPLOSIO HAZARD

Flammable fumes, such as solvent and paint fumes, in

work area

canigniteorexplode.Paint

or solvent ﬂowing through the equipment can cause static sparking. To help prevent re 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).

• Ground all equipment in the work area. See

Grounding

instructions.

• 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.

• Use only grounded hoses.

•

Stop operation immediately

if static sparking occurs or you feel a shock

Do not use

equipment until you identify and correct the problem.

• Keep a working re extinguisher in the work area.

Static charge may build up on plastic parts during cleaning and could discharge and ignite

ﬂammable vapors. To help prevent re and explosion:

• Clean plastic parts only in well ventilated area.

• Donotcleanwithadrycloth.

• Do not operate electrostatic guns in equipment work area.

EQUIPME T 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 Safety Data Sheet (SDS) from distributor or retailer.

• Turn off all equipment and follow the

Pressure Relief Procedure

when equipment is not in use.

• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine

manufacturer’s replacement parts only.

Warnings

WARNING

THERMAL EXPA SIO HAZARD

Fluids subjected to heat in con ned spaces, including hoses, can create a rapid rise in pressure

due to the thermal expansion. Over-pressurization can result in equipment rupture and serious

injury.

• Openavalvetorelievetheﬂuidexpansionduringheating.

• Replace hoses proactively at regular intervals based on your operating conditions.

PLASTIC PARTS CLEA I G SOLVE T HAZARD

Many solvents can degrade plastic parts and cause them to fail, which could cause serious

injury or property damage.

• Use only compatible water-based solvents to clean plastic structural or pressure-containing

parts.

•See

Technical Data

in this and all other equipment instruction manuals. Read ﬂuid and

solvent manufacturer’s Safety Data Sheet (SDS) and recommendations.

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 Safety Data Sheet (SDS) to know the speci c hazards of the ﬂuids you are using.

• Store hazardous ﬂuid in approved containers, and dispose of it according to applicable

guidelines.

BUR HAZARD

Equipment surfaces and ﬂuid that’s heated can become very hot during operation. To avoid

severe burns:

• Do not touch hot ﬂuid or equipment.

PERSO AL PROTECTIVE EQUIPME T

Wear appropriate protective equipment when in the work area to help prevent serious injury,

including eye injury, hearing loss, inhalation of toxic fumes, and burns. This protective

Key Points:

• Pumps are available with an AC or Brushless

DC (BLDC) motor, or with just a gearbox (for

applications where a motor already is available).

• Graco recommends the use of a motor soft

starter or a VFD (PN 16K911 or 16K912) in the

electrical circuit for all installations. See the

motor manufacturer’s recommendations for proper

installation when using either of these components.

In all cases, make sure all products are installed in

accordance with local codes and regulations.

• BLDC motors are controlled by the Graco Motor

Control that is supplied with the pump.

• The standard AC motor (not ATEX or

Explosionproof) and the BLDC motor are available

in models without a compressor, with a 120V

compressor, or with a 240V compressor.

• The BLDC motor is available in models that

are cart mounted. Cart Mounting Kit 24Y543 is

available for other models.

disassembly.

See the Operation Manual (334188) for troubleshooting or error information on the Graco Motor Control.

Problem Cause Solution

Pump is running too fast, causing

cavitation before prime. Slow down the motor controller

(VFD or Graco Motor Control)

Center section has no air pressure,

or air pressure is too low. Apply air pressure to center section

per your application requirements.

Check valve ball is severely worn or

wedged in seat or manifold. Replace the ball and seat.

the Operation manual.

Seat is severely worn. Replace the ball and seat.

Outlet or inlet is restricted. Remove therestriction.

Inlet ttings or manifolds are loose. Tighten.

Pump cycles but will not prime

and/or pump.

Manifold o-rings are damaged. Replace o-rings.

properly.

Check the connection.

Suction line is clogged. Inspect; clear.

Check balls are sticky or leaking . Clean or replace.

Pump ﬂow rate is erratic.

Diaphragm (or backup) ruptured. Replace.
