Priming the Pump
This procedure is required when...
• the pump is used for the first time
• whenever one or more of the inlet tubes contains air gaps or is dry for other 
reasons
The purpose of priming is to remove all air bubbles from the pump and its inlet 
tubes.
Propan-2-ol (alternative names: isopropanol, isopropyl alcohol, IPA) is the best 
solvent for priming the pump from dry and has the advantage of being 
miscible with most normal phase or reverse phase solvents (check a solvent 
miscibility table if unsure).
WARNING
Toxic, flammable and hazardous solvents, samples and reagents
The handling of solvents, samples and reagents can hold health and safety risks.
➔ When working with these substances observe appropriate safety procedures (for 
example by wearing goggles, safety gloves and protective clothing) as described in 
the material handling and safety data sheet supplied by the vendor, and follow good 
laboratory practice.
➔ The volume of substances should be reduced to the minimum required for the 
analysis.
➔ Do not operate the instrument in an explosive atmosphere.
NOTE
Avoid running the solvent reservoirs to emptiness by using the Bottle Filling monitor. Use a 
syringe to fill the solvent tubes, the pump will not pump air.
NOTE
Before starting the procedure ensure that all the solvent lines are connected to the pump 
as detailed in the pump installation manual, and that the waste tubes are safely positioned 
in a suitable waste solvent container. Ensure that the pump is controlled by computer 
software or the Instant Pilot controller and that the flow rate is set to zero.
