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 stat-
y
ed 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 dis-
pensing device is clean and in proper working condi-
tion.
STATIC SPARK. Can cause explosion re-
WARNING
sulting in severe injury or death. Ground pump and
pumping system.
Use the pump grounding screw terminal provided. Use
y
ARO® part no. 66885-1 ground kit or connect a suitable
ground wire (12 ga. min.) 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
y
electrical path to ground. Test with an ohmmeter from
each component (e.g., hoses, pump, clamps, contain-
er, spray gun, etc.) to ground to insure continuity.
Ohmmeter should show 0.1 ohms or less.
Submerse the outlet hose end, dispensing valve or de-
y
vice 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 contaminants.
WARNING
Can cause severe injury. Pipe exhaust away from work
area 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 1" minimum i.d. hose between the
y
pump and the muffler.
HAZARDOUS PRESSURE. Can result in seri-
WARNING
ous 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
outlet 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.

OPERATING AND SAFETY PRECAUTIONS

HAZARDOUS MATERIALS
HAZARDOUS PRESSURE
Obtain Material Safety Data Sheets on all materials
y
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, fluid caps, manifolds and
y
all wetted parts to assure compatibility before using
with solvents of this type.
MISAPPLICATION HAZARD. Do not use mod-
WARNING
els containing aluminum wetted parts with food prod-
ucts for human consumption. Plated parts can contain
trace amounts of lead.
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 on me-
CAUTION
chanical 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 flexi-
y
ble 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
y
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
