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

EXCESSIVE AIR PRESSURE

STATIC SPARK

EXCESSIVE AIR PRESSURE. Can cause person-

WARNING

al injury, pump damage or property damage.

Do not exceed the maximum inlet air pressure as stat-

ed on the pump model plate.

Be sure material hoses and other components are

able to withstand fluid pressures developed by this

pump. Check all hoses for damage or wear. Be certain

dispensing device is clean and in proper working con-

dition.

STATIC SPARK. Can cause explosion resulting

WARNING

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, recirculat-

ing or spraying flammable materials such as paints,

solvents, lacquers, etc. or used in a location where

surrounding atmosphere is conducive to spontaneous

combustion. Ground the dispensing 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 elec-

trical path to ground. Test with an ohmmeter from

each component (e.g., hoses, pump, clamps, contain-

er, spray gun, etc.) to ground to ensure 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.

Pump exhaust may contain contaminants.

WARNING

Can cause severe injury. Pipe exhaust away from work

area and personnel.

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 hazardous or inflammable materials.

Use a grounded 3/8" minimum ID hose between the

pump and the muffler.

HAZARDOUS PRESSURE. Can result in se-

WARNING

rious injury or property damage. Do not service or

clean pump, hoses or dispensing valve while the sys-

tem is pressurized.

Disconnect air supply line and relieve pressure from

the system by opening dispensing valve or device and

/ or carefully and slowly loosening and removing out-

let hose or piping from pump.

HAZARDOUS MATERIALS. Can cause serious

injury or property damage. Do not attempt to return

OPERATING AND SAFETY PRECAUTIONS

HAZARDOUS MATERIALS

HAZARDOUS PRESSURE

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.

Obtain Material Safety Data Sheets on all materials

from the supplier for proper handling instructions.

EXPLOSION HAZARD. Models containing

WARNING

aluminum parts cannot be used with 1,1,1-trichlo-

roethane, methylene 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.

MISAPPLICATION HAZARD. Do not use

models containing aluminum wetted parts with food

products for human consumption. Plated parts can

WARNING

contain trace amounts of lead.

Verify the chemical compatibility of the

CAUTION

pump wetted parts and the substance being pumped,

flushed or recirculated. Chemical compatibility may

change with temperature and concentration of the

chemical(s) within the substances being pumped,

flushed or circulated. For specific fluid compatibility,

consult the chemical manufacturer.

Maximum temperatures are based on me-

CAUTION

chanical stress only. Certain chemicals will signifi-

cantly reduce maximum safe operating temperature.

Consult the chemical manufacturer for chemical com-

patibility and temperature limits. Refer to PUMP DATA

on page 1 of this manual.

Be certain all operators of this equipment

CAUTION

have been trained for safe working practices, under-

stand it's limitations, and wear safety goggles / equip-

ment when required.

Do not use the pump for the structural sup-

CAUTION

port of the piping system. Be certain the system com-

ponents are properly supported to prevent stress on

the pump parts.

Suction and discharge connections should be flexi-

ble connections (such as hose), not rigid piped, and

should be compatible with the substance being

pumped.

Prevent unnecessary damage to the pump.

CAUTION

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.

Use only genuine ARO® replacement parts to

CAUTION

assure compatible pressure rating and longest service

life.

Install the pump in the vertical position.

NOTICE

The pump may not prime properly if the balls do not

check by gravity upon start-up.

Re-torque all fasteners before operation.

NOTICE

Creep of housing and gasket materials may cause

fasteners to loosen. Re-torque all fasteners to ensure

against fluid or air leakage.

Replacement warning labels are available
