READ, UNDERSTAND, AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.

EXCESSIVE AIR PRESSURE

STATIC SPARK

WARNING EXCESSIVE AIR PRESSURE. Can cause person-

al injury, pump damage or property damage.

Do not exceed the maximum inlet air pressure as stated on the

pump model plate.

Be sure material hoses and other components are able to with-

stand fluid pressures developed by this pump. Check all hoses

for damage or wear. Be certain dispensing device is clean and

in proper working condition.

WARNING STATIC SPARK. Can cause explosion resulting in

severe injury or death. Ground pump and pumping system.

Sparks can ignite flammable material and vapors.

The pumping system and object being sprayed must be

grounded when it is pumping, flushing, recirculating or spray-

ing flammable materials such as paints, solvents, lacquers,

etc. or used in a location where surrounding atmosphere is

conducive to spontaneous combustion. Ground the dispens-

ing valve or device, containers, hoses and any object to which

material is being pumped.

Secure pump, connections and all contact points to avoid

vibration and generation of contact or static spark.

Consult local building codes and electrical codes for specific

grounding requirements.

After grounding, periodically verify continuity of electrical path

to ground. Test with an ohmmeter from each component (e.g.,

hoses, pump, clamps, container, spray gun, etc.) to ground to

insure continuity. Ohmmeter should show 0.1 ohms or less.

Submerse the outlet hose end, dispensing valve or device in

the material being dispensed if possible. (Avoid free streaming

of material being dispensed.)

Use hoses incorporating a static wire.

Use proper ventilation.

Keep inflammables away from heat, open flames and sparks.

Keep containers closed when not in use.

WARNING Pump exhaust may contain contaminants. Can

cause severe injury. Pipe exhaust away from work area and per-

sonnel.

In the event of a diaphragm rupture, material can be forced out

of the air exhaust muffler.

Pipe the exhaust to a safe remote location when pumping haz-

ardous or inflammable materials.

Use a grounded 3/4" minimum i.d. hose between the pump and

the muffler.

WARNING HAZARDOUS PRESSURE. Can result in serious

injury or property damage. Do not service or clean pump,

hoses or dispensing valve while the system is pressurized.

Disconnect air supply line and relieve pressure from the sys-

tem by opening dispensing valve or device and / or carefully

and slowly loosening and removing outlet hose or piping from

pump.

WARNING HAZARDOUS MATERIALS. Can cause serious in-

jury or property damage. Do not attempt to return a pump to the

factory or service center that contains hazardous material.

Safe handling practices must comply with local and national

laws and safety code requirements.

OPERATING AND SAFETY PRECAUTIONS

HAZARDOUS MATERIALS

HAZARDOUS PRESSURE

Obtain Material Safety Data Sheets on all materials from the

supplier for proper handling instructions.

WARNING EXPLOSION HAZARD. Models containing alumi-

num wetted parts cannot be used with III.-Trichloroethane, Me-

thylene Chloride or other Halogenated Hydrocarbon solvents

which may react and explode.

Check pump motor section, fluid caps, manifolds and all

wetted parts to assure compatibility before using with solvents

of this type.

WARNING MISAPPLICATION HAZARD. Do not use models

containing aluminum wetted parts with food products for hu-

man consumption. Plated parts can contain trace amounts of

lead.

CAUTION Verify the chemical compatibility of the pump

wetted parts and the substance being pumped, flushed or re-

circulated. Chemical compatibility may change with tempera-

ture and concentration of the chemical(s) within the

substances being pumped, flushed or circulated. For specific

fluid compatibility, consult the chemical manufacturer.

CAUTION Maximum temperatures are based on mechani-

cal stress only. Certain chemicals will significantly reduce

maximum safe operating temperature. Consult the chemical

manufacturer for chemical compatibility and temperature lim-

its. Refer to PUMP DATA on page 1 of this manual.

CAUTION Be certain all operators of this equipment have

been trained for safe working practices, understand it's limita-

tions, and wear safety goggles / equipment when required.

CAUTION Do not use the pump for the structural support of

the piping system. Be certain the system components are

properly supported to prevent stress on the pump parts.

Suction and discharge connections should be flexible connec-

tions (such as hose), not rigid piped, and should be compatible

with the substance being pumped.

CAUTION Prevent unnecessary damage to the pump. Do

not allow pump to operate when out of material for long periods

of time.

Disconnect air line from pump when system sits idle for long

periods of time.

CAUTION Use only genuine ARO replacement parts to as-

sure compatible pressure rating and longest service life.

NOTICE

RE-TORQUE ALL FASTENERS BEFORE OPERA-

TION. Creep of housing and gasket materials may cause fas-

teners to loosen. Re-torque all fasteners to insure against fluid

or air leakage.
