HAZARDOUS MATERIALS
HAZARDOUS PRESSURE
WARNING EXCESSIVE AIR PRESSURE. Can cause perĆ
sonal injury, pump damage or property damage.
S Do not exceed the maximum inlet air pressure as stated on the
pump model plate.
S Be sure material hoses and other components are able to
withstand fluid pressures developed by this pump. Check all
hoses for damage or wear. Be certain dispensing device is
clean and in proper working condition.
WARNING
STATIC SPARK. Can cause explosion resulting
in severe injury or death. Ground pump and pumping system.
S Use the pump grounding screw terminal provided. Use Aro
Part No. 66885-1 Ground Kit or connecta suitable ground wire
(12 ga. min.) to a good earth ground source.
S Secure pump, connections and all contact points to avoid
vibration and generation of contact or static spark.
S Consult local building codes and electrical codes for specific
grounding requirements.
S After grounding, periodically verify continuity of electrical
path to ground. Test with an ohmmeter from each component
(e.g., hoses, pump, clamps, container, spray gun, etc.) to
ground to insure continuity. Ohmmeter should show 100
ohms or less.
S Submerse the outlet hose end, dispensing valve or device in
the material being dispensed if possible. (Avoid free streamĆ
ing of material being dispensed.)
S Use hoses incorporating a static wire.
S Use proper ventilation.
S Keep inflammables away from heat, open flames and sparks.
S 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.
S In the event of a diaphragm rupture material can be forced out
of the air exhaust muffler.
S Pipe the exhaust to a safe remote location when pumping hazĆ
ardous or inflammable materials.
S Use a grounded 3/4" min. I.D. hose between the the pumpand
the muffler.
WARNING
HAZARDOUS PRESSURE. Can result in serious
injury or property damage. Do not service or clean pump,
hoses or dispensing valve while the system is pressurized.
S Disconnect air supply line and relieve pressure from the sysĆ
tem by opening dispensing valve or device and/or carefully
and slowly loosening and removing outlet 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 centerthatcontains hazardous material.
Safe handling practices must comply with local and national
laws and safety code requirements.
S Obtain Material Safety Data Sheets on all materials from the
supplier for proper handling instructions.
WARNING EXPLOSION HAZARD. Models containing aluĆ
minum wetted parts cannot be used with III.-Trichloroethane,
Methylene Chloride or other Halogenated Hydrocarbon solĆ
vents which may react and explode.
S Check pump motor section, fluid caps, manifolds and all
wetted parts to assure compatibility before using with solĆ
vents of this type.
CAUTION Verify the chemical compatibility of the pump
wetted parts and the substance being pumped, flushed or reĆ
circulated. Chemical compatibility may change with temperaĆ
ture and concentration of the chemical(s) within the
substances being pumped, flushed or circulated. Consult
ARO Form No. 8677-P, Fluid Compatibility Guide, for informaĆ
tion on chemical compatibility.
CAUTION
Maximum temperatures are based on mechaniĆ
cal stress only. Certain chemicals will significantly reduce
maximum safe operating temperature. Consult Fluid CompatĆ
ibility Guide for chemical compatibility and temperature limĆ
its. 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, understand it's limitaĆ
tions, and wear safety goggles/equipment when required.
CAUTION
Do not use the pump for the structuralsupport of
the piping system. Be certain the system components are
properly supported to prevent stress on the pump parts.
S Suction and discharge connections should be flexible conĆ
nections (such as hose), not rigid piped, and should be comĆ
patible with the substance being pumped.
CAUTION Prevent unnecessary damage to the pump. Do
not allow pump to operate when out of material for long periĆ
ods of time.
S Disconnect air line from pump when system sits idle for long
periods of time.
CAUTION
Use only genuine ARO replacement parts to asĆ
sure compatible pressure rating and longest service life.
