TUBE COLLECTOR
When the tube collector is separated from the brix manifold, the tube collec-
tor cover plate can be removed to expose the product tubing (
Fig.31 ). On a
8 to 10 button dispenser, the syrup tubes in positions 1, 3, 8, and 10 ( see
Fig.31 ) are standard syrup tubes. The yellow tubes in positions 2, 4, 7, and
9 ( see Fig.31 ) are syrup barrier tubes which should be used for energy
drinks and pungent syrups such as root beer and punch. The blue tubes in
positions 5 and 6 are Soda and Water. NOTE: All positions with barrier
tubes are indicated by yellow highlighted numbers on the manifold
label located on top of the tube collector.
All syrup positions have “B” interconnect fittings and red “B” lock rings. The
Soda and Water positions have “A” interconnect fittings and red “B” lock
rings. The letter B is molded into the side of the “B” interconnect fittings.
(
Fig.32 ). The letter A is molded into the “A” interconnect fittings( Fig.33 ).
12 button dispensers have barrier tubes in syrup positions 4, 5, 10 and 11.
14 button dispensers have barrier tubes in syrup positions 4, 5, 10, and 11.
HANDLE REMOVAL
After the dispenser has been depressurized: Remove the four slot screws in
the rear of handle heel. Slide the heel back and away from the handle
(
Fig.34 ). The split heel may be separated ( Fig.34 ) and removed from the
sheathing for replacement. Loosen and remove the two retainer posts from
the rear of the handle, using a 5/16” hex driver, a 5/16” or small adjustable
wrench. The top center of the retainer plate is marked with a stamped num-
ber “10”. Pull the retainer plate and tubing (with ferrules and caps) away
from the handle. This allows for removal and replacement of the tube seal
o-rings and ferrule caps and ferrules.
REPLACING A PRODUCT TUBE
Disconnect the handle and sheathing assembly from the manifold. Remove
the Tube Collector Cover screws to gain access to the tube-ends and inter-
connect fittings. Lift up on the desired tube’s interconnect fitting and unsnap
it to separate it from the tube collector. The Individual tube can now be re-
placed in the field. Remove the four screws from the handle heel and slide
the heel and sheathing away from the handle. Loosen and remove the two
retainer posts, using a hex driver, wrench, or pliers, from the rear of the han-
dle. NOTE: The number “10” is stamped into the retainer plate at the top to
aid proper tubing to handle orientation during re-assembly. Pull the retainer
plate and tubing (with ferrules and caps) away from the handle.
A new tube assembly, with an interconnect fitting and lock ring installed,
should be ordered from the factory. Cut the old interconnect fitting off of the
old tube. Tape the new tube’s end to the end of the old tube. Slowly pull
the tube through the sheathing all the way to the back of the retainer plate.
Un-tape the tubes and discard the old tube. Insert the new tube’s end
through the open hole in the retainer plate about 1 to 1-1/2”. Dip the tube
end in hot water for 3 seconds and then install the ferrule into the tube end.
Install the ferrule cap onto the tube end with ferrule installed. Push all of the
tubes’ back to the retainer plate surface. Align the mark to the top of the
handle while inserting all ten tube ends with ferrules and caps back into their
o-rings in the back of the handle. Once all ten are properly inserted, re-
install the two retainer posts while visually confirming that all ten ferrule caps
are centered in their respective tube seal o-rings. Do not over-tighten the
retainer posts. Reinstall the heel and all four heel screws. Do not over-
tighten the screws.
