4) Insert the piston into the chamber of the dispensing head
body making certain to align the square notch of the piston
with the rectangular notch at the front of the dispense head.
5) Turn the dispense head over and install the 4" diameter
O-ring into O-ring groove located in the back of the head.
Lightly lubricate the O-ring with the sanitary lubricant.
2) First, remount the end piston O-rings onto the end pistons.
Simply roll onto the piston until they drop into the O-ring
notches.
3) Once the O-rings have been mounted, liberally lubricate the
area between the two O-rings. Place a bead of lubricant
around the entire piston as shown.
Spread the lubricant on the surface area between the two O-
rings and the O-rings as well. This will ensure free movement of
the dispense handles once the head is completely assembled.
