READ, UNDERSTAND AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.
EXCESSIVE AIR PRESSURE
STATIC SPARK
EXCESSIVE AIR PRESSURE. Can cause personal
WARNING
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 fl uid pressures developed by this pump. Check
all hoses for damage or wear. Be certain dispensing device
is clean and in proper working condition.
STATIC SPARK. Can cause explosion resulting in
WARNING
severe injury or death. Ground pump and pumping system.
Sparks can ignite fl ammable material and vapors.
The pumping system and object being sprayed must be
grounded when it is pumping, fl ushing, 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.
Use the pump grounding screw terminal provided. Use ARO®
part no. 66885-1 ground kit or connect a suitable ground wire
(12 ga. minimum) to a good earth ground source.
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-
cifi 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.
Pump exhaust may contain contaminants. Can
WARNING
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 muffl er.
Pipe the exhaust to a safe remote location when pumping
hazardous or infl ammable materials.
Use a grounded 3/4" minimum i.d. hose between the pump
and the muffl er.
HAZARDOUS PRESSURE. Can result in serious
WARNING
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.

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.
Obtain Material Safety Data Sheets on all materials from
the supplier for proper handling instructions.
EXPLOSION HAZARD. Models containing alu-
WARNING
minum parts cannot be used with 1,1,1-trichloroethane,
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 sol-
vents of this type.
MISAPPLICATION HAZARD. Do not use models
WARNING
containing aluminum wetted parts with food products
for human consumption. Plated parts can contain trace
amounts of lead.
Verify the chemical compatibility of the pump
CAUTION
wetted parts and the substance being pumped, fl 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-
cifi c fl uid compatibility, consult the chemical manufacturer.
Maximum temperatures are based on mechanical
CAUTION
stress only. Certain chemicals will signifi 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.
Be certain all operators of this equipment have
CAUTION
been trained for safe working practices, understand it's
limitations, and wear safety goggles / equipment when re-
quired.
Do not use the pump for the structural support of
CAUTION
the piping system. Be certain the system components are
properly supported to prevent stress on the pump parts.
Suction and discharge connections should be fl exible con-
nections (such as hose), not rigid piped, and should be
compatible with the substance being pumped.
Prevent unnecessary damage to the pump. Do
CAUTION
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 as-
CAUTION
sure compatible pressure rating and longest service life.
