Inserting the return spring (when applicable)
To insert the return self-priming spring follow the steps below:
1. Make sure that the Zippette
Pro
is completely empty. For ease of operation, assemble the Zippette
Pro
onto
an empty reservoir bottle and turn the dispense anti-drip tap to ‘Open’ position.
2. Turn the volume adjustment knob, to set the Zippette
Pro
to the max dispense volume of 30 ml (Drawing 1).
3.
Turn the fixing ring which is located at the bottom of the Zippette

piston sleeve until its raised rib is
aligned with the front piston sleeve slot and remove by gently pulling down (Drawing 1). The fixing ring
should stay on the barrel protection inner sleeve (Drawing 2).
4.
Press the two fixing levers on the back of the piston sleeve inwards (Drawing 2), and lever the back piston
sleeve away from the front sleeve assembly (Drawing 3).
5. Remove the front sleeve assembly from the piston locator and move the piston out of its glass barrel
(Drawing 3 & 4).
6. Carefully guide the piston through the spring, and locate the piston back into its glass barrel (Drawing 5).
7. Reassemble the front Zippette
Pro
piston sleeve (Drawing 5) making sure that the cursor locates under the
stop ring (Drawing 5).

Refit the back piston sleeve and pull up the fixing ring (Drawing 6) – turn it half circle to locate it onto the
