WARNING
EXCESSIVE GAS PRESSURE. Can cause per-
sonal injury, pump damage or property damage.
Do not exceed the maximum inlet gas 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.
WARNING
STATIC SPARK. Can cause explosion result-
ing in severe injury or death. Ground pump and
pumping system.
Use the pump ground lug provided. Connect to a 12
ga. (minimum) wire (kit is included) to a good earth
ground source.
Sparks can ignite fl ammable material and vapors.
The pump must be electrically grounded using the
grounding conductor provided. Improper grounding
can cause improper and dangerous operation.
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.
WARNING
Pump exhaust may contain contaminants.
Can cause severe injury. Pipe exhaust away from work
area and personnel.
The gas outlet of the pump must be vented to a safe lo-
cation in accordance with local codes or, in the absence
of local codes, an industry or nationally recognized
code having jurisdiction over the specifi c installation.
Use a grounded 3/8” minimum i.d. hose between the
pump and the muffl
er.
WARNING
HAZARDOUS PRESSURE. Can result in seri-
ous injury or property damage. Do not service or
clean pump, hoses or dispensing valve while the sys-
tem is pressurized.
Disconnect gas supply line and relieve pressure from
the system by opening dispensing valve or device and
/ or carefully and slowly loosening and removing out-
let hose or piping from pump.
WARNING
HAZARDOUS MATERIALS. Can cause 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

OPERATING AND SAFETY PRECAUTIONS
READ, UNDERSTAND AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.
requirements.
Obtain Material Safety Data Sheets on all materials
from the supplier for proper handling instructions.
WARNING
EXPLOSION HAZARD. Models containing alu-
minum wetted 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.
CAUTION
Verify the chemical compatibility of the
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.
CAUTION
Maximum temperatures are based on
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.
CAUTION
Be certain all operators of this equipment
have been trained for safe working practices, under-
stand it’s limitations, and wear safety goggles / equip-
ment when required.
CAUTION
Do not use the pump for the structural sup-
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.
CAUTION
Prevent unnecessary damage to the pump.
Do not allow pump to operate when out of material
for long periods of time.
Disconnect gas line from pump when system sits idle
for long periods of time.
CAUTION
Use only genuine ARO® replacement parts
to assure compatible pressure rating and longest ser-
vice life.
NOTICE
Install the pump in the vertical position.
The pump may not prime properly if the balls do not
check by gravity upon start-up.
NOTICE
Re-torque all fasteners before operation.
Creep of housing and gasket materials may cause
fasteners to loosen. Re-torque all fasteners to insure
against fl uid or gas leakage.
NOTICE
Replacement warning labels are available
upon request: “Static Spark” pn \ 93616-1, Diaphragm
Rupture” pn \ 93122.
WARNING
= Hazards or unsafe practices which
could result in severe personal injury,
death or substantial property damage.
CAUTION
= Hazards or unsafe practices which
could result in minor personal injury,
product or property damage.
NOTICE
= Important installation, operation or
maintenance information.
