WARNING EXCESSIVE AIR PRESSURE. Can cause per- sonal injury, pump damage or property damage.
yDo not exceed the maximum inlet air pressure as stated on the pump model plate.
yBe 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 con- dition.
WARNING STATIC SPARK. Can cause explosion result- ing in severe injury or death. Ground pump and pumping system.
yUse the pump grounding screw terminal provided. Use ARO® part no.
ySecure pump, connections and all contact points to avoid vibration and generation of contact or static spark.
yConsult local building codes and electrical codes for specific grounding requirements.
yAfter 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.
ySubmerse the outlet hose end, dispensing valve or device in the material being dispensed if possible. (Avoid free streaming of material being dispensed.)
yUse hoses incorporating a static wire.
yUse proper ventilation.
yKeep inflammables away from heat, open flames and sparks.
yKeep containers closed when not in use.
WARNING Pump exhaust may contain contaminants. Can cause severe injury. Pipe exhaust away from work area and personnel.
yIn the event of a diaphragm rupture, material can be forced out of the air exhaust muffler.
yPipe the exhaust to a safe remote location when pumping hazardous or inflammable materials.
yUse a grounded 1” minimum i.d. hose between the pump and the muffler.
WARNING HAZARDOUS PRESSURE. Can result in seri- ous injury or property damage. Do not service or clean pump, hoses or dispensing valve while the sys- tem is pressurized.
yDisconnect 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.
yObtain Material Safety Data Sheets on all materials from the supplier for proper handling instructions.
WARNING EXPLOSION HAZARD. Models containing aluminum parts cannot be used with
yCheck 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 signifi- cantly reduce maximum safe operating temperature. Consult the chemical manufacturer for chemical com- patibility 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, under- stand it’s limitations, and wear safety goggles / equip- ment when required.
CAUTION Do not use the pump for the structural sup- port of the piping system. Be certain the system com- ponents are properly supported to prevent stress on the pump parts.
ySuction and discharge connections should be flex- ible 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.
yDisconnect 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 & Diaphragm Rupture” pn \ 94080.
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.
