Indicates information considered important, but not
hazard-related.
• Do not exceed the maximum inlet air pressure noted on the pump model plate.
• Sparkcanignitefromammablematerialandvapors.
• You must ground the pumping system when in use. Ground the dispensing valve or device,
containers, hoses and the object you are pumping to.
• Keepinammablesawayfromheat,openamesandsparks.
• Pump exhaust may contain contaminants. Pipe exhaust away from work area and people.
• 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.
• Explosion Hazard. Models containing aluminum-wetted parts cannot be used with
III-Trichloroethane, Methylene Chloride or other Halogenated Hydrocarbon solvents which
may react and explode.
• Air pressure should not exceed 115 psi (JDI-DPES) or 110 psi (JDI-DPES-UL).
• Check all hoses for damage or wear.
• Ensure dispensing device is clean and in proper working condition.
• Use proper ventilation.
• Verify the chemical compatibility of the pump-wetted parts and the substance you are
pumping,ushing,orrecirculating.
• Do not use the pump for the structural support of the piping system. Ensure system
components are supported properly to prevent stress on the pump.
• 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
extended periods of time.
• The size of the air delivery pipe must be big enough for proper air delivery.
• Secure pump, connections and all contact points to avoid vibration and generation of
contact or static spark.
• After grounding, periodically verify continuity of electrical path to ground. Test with an
Ohmmeter for each component to ground to ensure continuity. Ohmmeter should show
1000 ohms or less.
• Keep closed when not in use.
• Consultlocalbuildingcodesandelectricalcodesforspecicgroundingrequirements.
• Usealtercapableoflteringoutparticleslargerthan50micronsontheairsupply.There
