PRE-MIX DROP-INS
Pre-mix fountain dispensing consists of a container of
beverage ready for dispensing, beverage delivery
system, carbon dioxide (CO
2) propellant, beverage
cooling system, and dispenser. We shall discuss each
component of this type of system within the context of
this manual.
The major advantage of a pre-mix system over most
other types is its flexibility. This flexibility is the ability to
go anywhere. Many pre-mix systems will operate without
electric power or separate water supply. Most drop-ins
are manufactured for post-mix. Unless otherwise stated,
operation and installation instructions are for post-mix.
STANDS
Stands are designed to accommodate drop-in ice bins
and to provide an enclosure for carbonators. See
instructions provided with those items for proper
installation and connections.
COLD PLATE BEVERAGE COOLING
A cold plate is a block of aluminum with serpentine
stainless steel tubes molded inside the aluminum block.
The cold plate is approximately the same length and
width as the bottom of the dispenser bin. Ice sits on top
of the cold plate and cools the cold plate. The stainless
steel tubes inside the cold plate carry carbonated water
(soda water), noncarbonated water (plain water) and
syrup to the beverage valves. While flowing through the
stainless steel tubes in the cold plate, water and syrup
are chilled to serving temperature.
UNIT INSPECTION
This section covers unpacking, inspecting, selecting location,
installing the unit, and preparing for operation. Thoroughly
inspect the unit upon delivery. Immediately report any damage
that occurred during transportation to the delivery carrier.
Request a written inspection report from a claims inspector to
document any necessary claim.
1. After the unit has been unpacked, remove the keys. The
key will be needed to perform brixing of valves. Hold onto
the keys until such time to forward them to the respective
owner/operator. Remove tape (which secures grid in
place in drain pan) from grid and other packing material.
2. Make sure all items are present and in good condition.
Loose shipped items in the carton include the drain kit
parts and the instructions.
3. Inspect unit for any external damages.
If you have an internal carbonated unit the unit is pre-plumbed
at the factory. The inlets for CO
2 and water are located behind
the splash panel. There are two inlets for water and one inlet
for CO
2. If you have questions refer to the plumbing diagram
on your equipment.
BEVERAGE VALVES
Post-mix beverage valves are designed to precisely meter the
flow of both water and syrup to obtain the proper mixing ratio.
The syrup and soda water components of the post-mix
beverage are mixed as they leave the beverage valve.
