HAZARDOUS PRESSURE
WARNING
EXCESSIVE AIR PRESSURE . Can cause
personal injury, pump damage or property damage .
y
Do not exceed the maximum inlet air pressure as stated
on the pump model plate .
y
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 .
y
Sparks can ignite flammable material and vapors .
y
The pumping system and object being sprayed
must be grounded when it is pumping, flushing,
recirculating or spraying flammable materials such
as paints, solvents, lacquers, etc . or used in a loca-
tion 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 .
y
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 .
y
Secure pump, connections and all contact points to
avoid vibration and generation of contact or static spark .
y
Consult local building codes and electrical codes for
specific grounding requirements .
y
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 ensure
continuity . Ohmmeter should show 0 .1 ohms or less .
y
Submerse the outlet hose end, dispensing valve or
device in the material being dispensed if possible .
(Avoid free streaming of material being dispensed .)
y
Use hoses incorporating a static wire .
y
Use proper ventilation .
y
Keep inflammables away from heat, open flames and
sparks .
y
Keep containers closed when not in use .
WARNING
Pump exhaust may contain contaminants .
Can cause severe injury . Pipe exhaust away from work
are and personnel .
y
In the event of a diaphragm rupture, material can be
forced out of the air exhaust muffler .
y
Pipe the exhaust to a safe remote location when
pumping hazardous or inflammable materials .
y
Use a grounded 3/8" minimum ID hose between the
pump and 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 .
y
Disconnect air supply line and relieve pressure from
the system 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 center that
contains hazardous material . Safe handling practices
must comply with local and national laws and safety
code requirements .
y
Obtain Material Safety Data Sheets on all materials
from the supplier for proper handling instructions .
WARNING
EXPLOSION HAZARD . Models containing
aluminum wetted parts cannot be used with 1,1,1-
trichloroethane, methylene chloride or other
halogenated hydrocarbon solvents which may react
and explode
.
y
Check pump motor section, fluid 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,
flushed or circulated . For specific fluid compatibility,
consult the chemical manufacturer .
CAUTION
Maximum temperatures are based
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 .
CAUTION
Be certain all operators of this equipment
have been trained for safe working practices,
understand it’s limitations, and wear safety goggles /
equipment when required .
CAUTION
Do not use the pump for the structural
support of the piping system . Be certain the system
components are properly supported to prevent stress
on the pump parts .
y
Suction and discharge connections should be flexible
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 .
y
Disconnect air 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
service life .
NOTICE
Replacement warning labels are
available upon request: “Static Spark” (93616-1) and
“Diaphragm Rupture” (93122) .
