READ, UNDERSTAND AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.
EXCESSIVE AIR PRESSURE
STATIC SPARK
EXCESSIVE AIR PRESSURE. Can cause per-
WARNING
sonal 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 dispens-
ing device is clean and in proper working condition.
STATIC SPARK. Can cause explosion result-
WARNING
ing in 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, recirculat-
ing or spraying flammable materials such as paints,
solvents, lacquers, etc. or used in a location where sur-
rounding atmosphere is conductive 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.
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
specifi c grounding requirements.
After grounding, periodically verify continuity of
electrical path to ground. Test with an ohmmeter
from each component (e.g., hoses, pump, clamps, con-
tainer, 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 infl ammables away from heat, open fl ames 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 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 seri-
WARNING
ous 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-

OPERATING AND SAFETY PRECAUTIONS
HAZARDOUS MATERIALS
HAZARDOUS PRESSURE
let hose or piping from pump.
HAZARDOUS MATERIALS. Can cause serious
WARNING
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
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, fl uid caps, manifolds and
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,
fl ushed or circulated. For specifi c fl uid compatibility,
consult the chemical manufacturer.
Maximum temperatures are based on
CAUTION
mechanical 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 flex-
ible 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.
Replacement warning labels are available
