WARNING

 

EXCESSIVE AIR PRESSURE. Can cause per- 

sonal 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 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. 

 

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 location where surrounding 

atmosphere is conducive to spontaneous combustion. 

Ground the dispensing valve or device, containers, hos-

es and any object to which material is being pumped.

 

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, con-

tainer, spray gun, etc.) to ground to insure 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 

area 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 3/4” 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 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.

 

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

 RE-TORQUE ALL FASTENERS BEFORE 

OPERATION. Creep of housing and gasket materials 

may cause fasteners to loosen. Re-torque all fasteners 

to insure against fluid or air leakage.

NOTICE

 Replacement warning labels are available 

upon request: Static Spark” (936161) and Diaphragm 

Rupture” (931221).

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.
