Assembly
The Zippette
Pro
is packed with the dispense nozzle attached and the inlet feed tube removed. The 300 mm
length of PTFE inlet tube provided should be trimmed to fit your particular reservoir. The bottom end should
be cut diagonally at a length that is close to the bottom of the container when the Zippette
Pro
is assembled
to the container. Longer lengths of inlet tube are available on request.
The threaded platform base of the Zippette
Pro
has a 30 mm screw thread for use with the recommended
accessories displayed on page 14. The assembled Zippette
Pro
is screwed to the reservoir using gentle hand
torque applied to the Zippette
Pro’s
threaded platform base only. Removal should also be by means of hand
torque applied to this same base.
Do not operate the piston until the unit is safely and fully mounted on the reservoir bottle.
