WARNING
EXCESSIVE AIR PRESSURE. Can cause personal
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
withstand uid 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.
Use the pump grounding screw provided. Use ARO® part
no. 66885-1 ground kit or connect a suitable ground wire
(12 ga. min.) to a good earth ground source.
Sparks can ignite ammable material and vapors.
The pumping system and object being sprayed must be
grounded when it is pumping, flushing, recirculating or
spraying flammable materials such as paints, solvents,
lacquers, etc. or used in a location where surrounding atmo-
sphere 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 spe-
ci c grounding requirements.
After grounding, periodically verify continuity of electrical
path to ground. Test with an ohmmeter from each compo-
nent (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
personnel.
In the event of a diaphragm rupture, material can be forced
out of the air exhaust mu er.
Pipe the exhaust to a safe remote location when pumping
hazardous or in ammable materials.
Use a grounded 3/8” minimum i.d. hose between the pump
and the mu er.
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
system 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
READ, UNDERSTAND AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.
Obtain Material Safety Data Sheets on all materials from
the supplier for proper handling instructions.
WARNING
EXPLOSION HAZARD. Models containing alumi-
num parts cannot be used with 1,1,1-trichloroethane, meth-
ylene 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 sol-
vents of this type.
WARNING
MISAPPLICATION HAZARD. Do not use models
containing aluminum wetted parts with food products
for human consumption. Plated parts can contain trace
amounts of lead.
CAUTION
Verify the chemical compatibility of the pump
wetted parts and the substance being pumped, ushed or
recirculated. Chemical compatibility may change with tem-
perature and concentration of the chemical(s) within the
substances being pumped, flushed or circulated. For spe-
ci c uid compatibility, consult the chemical manufacturer.
CAUTION
Maximum temperatures are based on mechanical
stress only. Certain chemicals will signi cantly reduce max-
imum safe operating temperature. Consult the chemical
manufacturer for chemical compatibility and temperature
limits. 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
limitations, and wear safety goggles / equipment when re-
quired.
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 exible con-
nections (such as hose), not rigid piped, and should be com-
patible 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
Install the pump in the vertical position. The
pump may not prime properly if the balls do not check by
gravity upon start-up.
NOTICE
Re-torque all fasteners before operation. Creep
of housing and gasket materials may cause fasteners to
loosen. Re-torque all fasteners to insure against uid or air
leakage.
NOTICE
Replacement warning labels are available upon
request: “Static Spark” pn \ 93616-1, Diaphragm Rupture”
pn \ 93122.
WARNING
= Hazards or unsafe practices which
could result in severe personal injury,
death or substantial property damage.
CAUTION
= Hazards or unsafe practices which
could result in minor personal injury,
product or property damage.
NOTICE
= Important installation, operation or
maintenance information.
