WARNING

 EXCESSIVE AIR PRESSURE. Can cause per- 

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 fluid 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 

resulting in severe injury or death. Ground pump and 

pumping system. 

Use the pump grounding screw terminal provided. 

Use 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 

avoid vibration and generation of contact or static 

spark.

Consult local building codes and electrical codes for 

specific 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 ensure 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 inflammables away from heat, open flames 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.

In the event of a diaphragm rupture, material can be 

forced out of the air exhaust muffler.

Pipe the exhaust to a safe remote location when 

pumping hazardous or inflammable materials.

Use a grounded 1” minimum i.d. 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.

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-

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 requirements.

OPERATING AND SAFETY PRECAUTIONS

READ, UNDERSTAND, AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.

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.

Check pump motor section, fluid caps, manifolds and 

all wetted parts to assure compatibility before using 

with solvents of this type.

WARNING

 MISAPPLICATION HAZARD. Do not use 

models containing aluminum wetted parts with food 

products for human consumption. Plated parts can 

contain trace amounts of lead.

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.

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.

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.

WARNING

Hazards or unsafe practices which 

could result in severe personal injury, 

death osr substantial property dam-

age.

CAUTION

Hazards or unsafe practices which 

could result in minor personal injury, 

product or property damage.
