READ, UNDERSTAND, AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.
EXCESSIVE AIR PRESSURE
STATIC SPARK
EXCESSIVE AIR PRESSURE. Can cause
WARNING
personal injury, pump damage or property damage.
Do not exceed the maximum inlet air pressure as stated
y
on the pump model plate.
Be sure material hoses and other components are able
y
to withstand fluid pressures developed by this pump.
Check all hoses for damage or wear. Be certain dispens-
ing device is clean and in proper working condition.
STATIC SPARK. Can cause explosion
WARNING
resulting in severe injury or death. Ground pump and
pumping system.
Sparks can ignite flammable material and vapors.
y
The pumping system and object being sprayed must
y
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.
Use the pump grounding screw terminal provided.
y
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
y
avoid vibration and generation of contact or static spark.
Consult local building codes and electrical codes for
y
specific grounding requirements.
After grounding, periodically verify continuity of elec-
y
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
y
device in the material being dispensed if possible.
(Avoid free streaming of material being dispensed.)
Use hoses incorporating a static wire.
y
Use proper ventilation.
y
Keep inflammables away from heat, open flames and
y
sparks.
Keep containers closed when not in use
y
Pump exhaust may contain contam-
y
WARNING
inants. Can cause severe injury. Pipe exhaust away
from work are and personnel.
In the event of a diaphragm rupture, material can be
y
forced out of the air exhaust muffler.
Pipe the exhaust to a safe remote location when
y
pumping hazardous or inflammable materials.
Use a grounded 3/8" minimum i.d. hose between the
y
pump and the muffler.
HAZARDOUS PRESSURE. Can result in
WARNING
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
y
the system by opening dispensing valve or device and
/ or carefully and slowly loosening and removing out-
let hose or piping from pump.

OPERATING AND SAFETY PRECAUTIONS
HAZARDOUS MATERIALS
HAZARDOUS PRESSURE
HAZARDOUS MATERIALS. Can cause
WARNING
serious injury 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
y
from the supplier for proper handling instructions.
EXPLOSION HAZARD. Models con-
y
WARNING
taining aluminum wetted 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
y
all wetted parts to assure compatibility before using
with solvents of this type.
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
CAUTION
on mechanical stress only. Certain chemicals will
significantly reduce maximum 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
CAUTION
have been trained for safe working practices,
understand it's limitations, and wear safety goggles /
equipment when required.
Do not use the pump for the structural
CAUTION
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
y
connections (such as hose), not rigid piped, and should
be compatible with the substance being pumped.
Prevent unnecessary damage to the
CAUTION
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
y
for long periods of time.
Use only genuine ARO replacement parts to
CAUTION
assure compatible pressure rating and longest service life.
