Warnings

The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama-

tion 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

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.

• Always wear impervious gloves when spraying or cleaning equipment.

• If this equipment is used with isocyanate material, see additional information on isocyanates in Iso-

cyanate Conditions Section of this manual.

PERSONAL PROTECTIVE EQUIPMENT

You must wear appropriate protective equipment when operating, servicing, or when in the operating

area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic

fumes, burns, and hearing loss. This equipment includes but is not limited to:

• Protective eyewear

• Clothing and respirator as recommended by the fluid and solvent manufacturer

• Gloves

• Hearing protection

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 working fire extinguisher in the work area.

ELECTRIC SHOCK HAZARD

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

tric shock.

• Turn off and disconnect power cord before servicing equipment.

• Use only grounded electrical outlets.

• Use only 3-wire extension cords.

• Ensure ground prongs are intact on power and extension cords.

• Do not expose to rain. Store indoors.

Warnings

313877G 5

PRESSURIZED EQUIPMENT HAZARD

Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin and

cause serious injury.

• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning,

checking, or servicing equipment.

• Tighten all fluid connections before operating the equipment.

• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.

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.

• Do not leave the work area while equipment is energized or under pressure. Turn off all equipment

and follow the Pressure Relief Procedure in this manual when equipment is not in use.

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

facturer’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.

PLASTIC PARTS CLEANING SOLVENT HAZARD

Use only compatible water-based solvents to clean plastic structural or pressure-containing parts. Many

solvents can degrade plastic parts and cause them to fail, which could cause serious injury or property

damage. See Technical Data in this and all other equipment instruction manuals. Read fluid and solvent

manufacturer’s warnings.

Grounding

313877G 9

Grounding

This product must be grounded. In the event of an elec-

trical short circuit, grounding reduces the risk of electric

shock by providing an escape wire for the electric cur-

rent.

Grounding plug units: this product is equipped with a

cord having a grounding wire with an appropriate

grounding plug. The plug must be plugged into an outlet

that is properly installed and grounded in accordance

with all local codes and ordinances.

Hard-wired units: the grounding wire must be used. All

electrical wiring must be done by a qualified electrician

and comply with all local codes and regulations.

Air and fluid hoses: use only electrically conductive

hoses.

Fluid supply container: follow local code.

Solvent pails used when flushing: follow local code.

Use only conductive metal pails, placed on a grounded

surface. Do not place the pail on a non-conductive sur-

face, such as paper or cardboard, which interrupts

grounding continuity.

Setup

10 313877G

Setup

Micrometer and LRT PD44 Only

1. Connect air supply to main air inlet on control box.

Air supply must include a shut-off/bleed valve that

bleeds pressure past the shut-off/bleed valve and

an air-water separator/filter.

2. Connect air lines from control box to dispense valve.

Match the number and color codes on the fittings

and connections. See the following table and illus-

tration.

3. Connect Dispense Valve I/O, and Start Options

logic cables. If level controls are installed, connect

Level Controls logic cables.

4. Adjust air pressure regulator to 80 psi (0.6 MPa,

6bar).

5. Perform Setup procedure for dispense valve and

feed system components. See Related Manuals on

page 3.
