5.1 First Operation
5.1.1 Priming the Feed Line
● Check that the product reservoir, the dispensing valve and the Footswitch are connected correctly
according to their instruction manuals.
☞
To avoid air bubbles during dispensing, the product line must be filled and then purged of air.
● Position the dispensing valve as specified in its instruction manual to ensure bubble-free filling of the
product line.
Place a container under the dispensing valve since the product will flow out.
● Switch the power switch 7 to the position I (ON).
● With the pressure regulator 8, set the
dispensing pressure to 0.50 bar
(approx. 7.00 psi).
● Press button until the product flows free of
bubbles from the dispensing needle.
● For viscous products, increase the pressure
slowly in steps until the product flows out.
Hold the dispensing valve pointing downward
to prevent uncontrolled squirting out of the product.
