Step 1: Unscrew injection head

Carefully unscrew the injection head with a 22 mm wrench.
•
If the wrench does not hold the injection head properly, rotate
the safety cylinder slightly.
•

Remove the valve (valve body and spring).
As soon as injection head and valve are dismounted: Ensure that the
exposed tip of the FreVAX™ is protected from dirt.
Hold the device with the head facing downwards in order to drain
residues of vaccine or rinsing fluid.
Step 2: Remove old cylinder
•
Unscrew the old cylinder with a 15 mm wrench.
•
Hold the device with the head facing downwards and only then (!)
remove the cylinder from the device by pulling. This will allow you
to drain remaining vaccine or rinsing fluid.
Step 3: Lubricate the piston rod
•
Prior to lubrication, clean the piston chamber and piston rod by wiping it with
a cotton cloth or Q-tip/cotton bud.
•
Lubricate the tip of the piston rod using a fingertip or Q-tip/cotton bud soaked
in the supplied white oil.
Step 4: Insert new cylinder
•
Lubricate the o-rings on the exterior wall of the new cylinder with
white oil.
•
Insert the new cylinder into the opening of the piston chamber and
press down until it sits firmly.

Remove the yellow protection cap, taking care that the o-ring
and valve below the protection cap will stay in place.
