To remove the valve plunger, it has to be in star position 1. You also have to be able to easily access the
valve plunger head with your fingers.
Take the valve plunger head3 (see Fig. 9.7.9) with your thumb and your forefinger and pull the valve
plunger out of the valve casing 2 (see Fig. 9.7.9). You will initially feel a slight resistance. The valve
plunger can then be pulled out easily.
NOTE
Do not use any pliers to pull out the valve plunger since this could damage the outside of the valve plunger
head.

Clean the valve plunger
1
(see Fig. 9.7.10) using a dry, clean cloth.
WARNING
Never use alcohol, cleaning agents or solvents to clean the valve plungers. Cleaning the o-rings using
these agents can result in malfunctions during placement operation (due to vacuum problems).
In particular, ensure that the recess 2 (see Fig. 9.7.10) of the valve plunger is free of grease.
Using a little ISOFLEX® TOPAS® NCA52 grease on a lint-free cloth, lightly grease the o-rings 3 and the
Viton o-ring 4. Make sure that some of the grease is also applied to the recess.
Push the valve plunger 3 (see Fig. 9.7.9, page 9 - 89) back into the valve casing 2 (see Fig. 9.7.9, page
9 - 89) until it reaches the stop.
In particular ensure that the plunger is not skewed when inserted, since this could damage the hole in the
valve casing.
Finally carry out a vacuum test.
