Operating And Safety Precautions

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

EXCESSIVE AIR PRESSURE	HAZARDOUS MATERIALS
STATIC SPARK	HAZARDOUS PRESSURE

WARNING EXCESSIVE AIR PRESSURE. Can cause perK sonal injury, pump damage or property damage.

SDo not exceed the maximum inlet air pressure as stated on the pump model plate.

SBe 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.

SUse 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.

SSecure pump, connections and all contact points to avoid vibration and generation of contact or static spark.

SConsult local building codes and electrical codes for specific grounding requirements.

SAfter 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.

SSubmerse the outlet hose end, dispensing valve or device in the material being dispensed if possible. (Avoid free streamK ing of material being dispensed.)

SUse hoses incorporating a static wire.

SUse proper ventilation.

SKeep inflammables away from heat, open flames and sparks.

SKeep containers closed when not in use.

WARNING Pump exhaust may contain contaminants. Can cause severe injury. Pipe exhaust away from work area and personnel.

SIn the event of a diaphragm rupture material can be forced out of the air exhaust muffler.

SPipe the exhaust to a safe remote location when pumping hazK ardous or inflammable materials.

SUse a grounded 3/4" min. I.D. hose between the pump and the muffler.

WARNING EXPLOSION HAZARD. Models containing aluK minum wetted parts cannot be used with III.-Trichloroethane, Methylene Chloride or other Halogenated Hydrocarbon solK vents which may react and explode.

SCheck pump motor section, fluid caps, manifolds and all wetted parts to assure compatibility before using with solK vents of this type.

CAUTION Verify the chemical compatibility of the pump wetted parts and the substance being pumped, flushed or reK circulated. Chemical compatibility may change with temperaK 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 informaK tion on chemical compatibility.

CAUTION Maximum temperatures are based on mechaniK cal stress only. Certain chemicals will significantly reduce maximum safe operating temperature. Consult Fluid CompatK ibility Guide for chemical compatibility and temperature limK 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 limitaK tions, 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.

SSuction and discharge connections should be flexible conK nections (such as hose), not rigid piped, and should be comK 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 periK ods of time.

SDisconnect air line from pump when system sits idle for long periods of time.

CAUTION Use only genuine ARO replacement parts to asK

sure compatible pressure rating and longest service life.

NOTICE Replacement warning labels are available upon request : ``Static Spark'' (93616-1) & ``Diaphragm Rupture'' (93122-1).

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.

SDisconnect air supply line and relieve pressure from the sysK 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 center that contains hazardous material. Safe handling practices must comply with local and national laws and safety code requirements.
