HAZARDOUSPRESSURE
WARNING
EXCESSIVEAIR PRESSURE.Can causeperson -
al injury, pump damage or property damage.
S Donot exceedthemaximum inletairpressure asstatedonthe
pump model plate.
S Besurematerialhosesandothercomponentsareabletowith-
standfluidpressuresdevelopedbythispump.Checkallhoses
for damageor wear. Be certaindispensing device isclean and
in proper working condition.
WARNING
STATICSPARK.Cancauseexplosionresultingin
severe injury or death. Ground pump and pumping system.
S Use the pump grounding screw terminal provided. Use ARO
part no. 66885-1 ground kit or connect a suitable ground wire
(12 ga. min.) to a good earth ground source.
S Secure pump, connections and all contact points to avoid
vibration and generation of contact or static spark.
S Consult local building codes and electrical codes for specific
grounding requirements.
S Aftergrounding,periodicallyverifycontinuityofelectricalpath
to ground.Test withan ohmmeter from each component(e.g.,
hoses, pump, clamps,container, spray gun, etc.)t o ground to
insure continuity. Ohmmeter should show 0.1 ohms or less.
S Submerse the outlet hose end, dispensing valve or device in
thematerialbeingdispensedifpossible.(Avoidfreestreaming
of material being dispensed.)
S Use hoses incorporating a static wire.
S Use p roper ventilation.
S Keep inflammables away from heat, open f lames and sparks.
S Keep containers closed when not in use.
WARNING
Pump exhaust may contain contaminants. Can

sonnel.
S Inthe eventofa diaphragmrupture,materialcan beforcedout
of the air exhaust muffler.
S Pipethe exhaustto asaferemote locationwhen pumpinghaz-
ardous or inflammable materials.
S Use a grounded 1” 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.
S Disconnect air supply line and relieve pressure from the sys-
tem by opening dispensing valve or device and / or carefully
andslowly loosening andremovingoutlet hoseorpipingfrom
pump.
WARNING
HAZARDOUSMATERIALS.Cancauseseriousin-
juryorpropertydamage.Donotattempttoreturnapumptothe
factory o r service center that contains hazardous material.
Safe handling practices must comply with local and national
laws and safety code requirements.
S Obtain Material Safety Data Sheets on all materials from the
supplier for proper handling instructions.
WARNING
EXPLOSIONHAZARD.Models containingalumi-
numwettedpartscannotbeusedwithIII.-Trichloroethane,Me-
thylene Chloride or other Halogenated Hydrocarbon solvents
which may react and explode.
S Check pump motor section, fluid caps, manifolds and all
wettedpartstoassurecompatibilitybeforeusingwithsolvents
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 temperaturelim-
its.RefertoPUMPDATAonpage1ofthismanual.
CAUTION
Be certain all operators of this equipment have
beentrained forsafeworking practices,understandit’slimita-
tions, and wear safety goggles / equipment when required.
CAUTION

the piping system. Be certain the system components are
properly supported to prevent stress on the pump parts.

tions(suchashose),notrigidpiped,andshouldbecompatible
with the substance being pumped.
CAUTION
Prevent unnecessary damage to the pump. Do
notallowpumptooperatewhenoutofmaterialforlongperiods
of time.
S 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.

Replacement warning labels are available upon
request: “Static Spark & Diaphragm Rupture” pn \ 94080.
