Service manual

CAUTION: In order to have even distribution of cold water, the cold-water circulating
lines must always be run in series even on multiple station installations.
IMPORTANT: Be sure to leave all connections and fittings exposed until after the entire
system has been pressure tested.
In order to insure maximum heat transfer between the braided plastic
lines (through which the water and soda are carried) and the circulating
tubing, it is necessary to tape these lines firmly together.
It is of utmost importance that the extended lines of the remote
installation be properly and adequately insulated. Failure to do this will
cause overloading of the refrigeration unit and ice bank, condensation
on the outside of the insulation and reduced cold drink dispensing
capacity.
CAUTION: All open ends, joints and connections of the insulation must be sealed air
tight to prevent outside air from entering the insulated duct. Outside air, which contains
moisture, would condense this moisture within the insulation duct resulting in the
insulation becoming wet, which would reduce its insulating qualities. Water dripping from
duct would also result.
Pressure Drop within the Carbonated Water Lines – All Soda systems will maintain the
pressure necessary to prevent any carbonation loss throughout the entire system even
while the valve is open.
Attention must be given to avoid restrictions in the lines, which may cause a reduction in
pressure upon the carbonated water and allow some of the gas to escape from the
carbonated water in the lines.
The pressure is measured on pounds per square inch and is the reduction in pressure
within the carbonated water line between the carbonator outlet and the valve inlet while
carbonated water is being drawn.
The amount of pressure drop will vary with the length of the line, size of the tubing used,
(inside Diameter), the rise of the line, and the flow of the carbonated water through the
line, (gallons per hour).
Carbonated water lift pressure is .45 pounds per foot rise.
The pressure drop within a carbonated water line should not exceed 30 P.S.I.
When soda lines are run more than 10 feet in any one direction a minimum of 3/8” tubing
is recommended. When soda lines are run more than 50 feet 1/2” tubing is
recommended.
Braided Plastic Tubing – The flexible braided plastic tubing is used for carbonated water..
It will withstand high pressure and is easily installed because of its flexibility but should
never be used in contact with hot water or steam lines.
