Dispensing head
The appropriate dispensing head for the size of tubing being used should be
attached to the Y arm block by loosening the red knob and lifting the
dispensing head clamp.
The dispensing head can then be inserted into the slot, the clamp lowered
and the red knob re-tightened.
In order to obtain the correct dispensing height, adjustable feet are fitted to
the base of the system.
An adjustable tray guide is also fitted to ensure that the filler trays locate
correctly.
Fine adjustment can be made using the dispensing head. It can be raised or
lowered by simply undoing the adjustable red knob, and sliding the guide to
the correct (200mm max) height, then re-tighten.
