How the Multiplex Works
Multiplex Model 42 & 44
• 1 HP refrigeration unit
• Post-Mix carbonated beverages and chilled carbonated
water: 21 gal (79 L) of syrup or carbonated water/day or
980 drinks/day (7,500 gal/yr)
• 250 ft (80 m) maximum conduit length
Super-Chil Model SC1000
• 1 HP refrigeration unit
• Chilled water: 29 gal (110 L) in 2 hrs (peak); 15 gal (57 L)
in 2 hrs (sustained 24 hrs)
• 250 ft (80 m) maximum conduit length
These refrigeration units are remote refrigeration units
that derive their peak capacity from the reserve ice bank.
These systems are controlled to cycle ON and OFF by the
operation of the ice control. The sensing probe that controls
the ice bank is located on an adjustable bracket in the water
bath.
Multiplex Model 50
• 2.2 HP refrigeration unit
• Post-Mix carbonated beverages and chilled carbonated
water: 42 gal (159 L) of syrup or carbonated water/day
or 2,000 drinks/day (15,000 gal/yr)
• 350 ft (107 m) maximum conduit length
Super-Chil Model SC2000
• 2.2 HP refrigeration unit
• Chilled water: 55 gal (208 L) in 2 hrs (peak); 30 gal (114 L)
in 2 hrs (sustained 24 hrs)
• 350 ft (107 m) maximum conduit length
These refrigeration units are remote refrigeration units
that derive their peak capacity from the reserve ice bank
produced by the operation of the compressor. These
systems are controlled to cycle ON and OFF by the
operation of the ice bank control. The sensing probe that
controls the ice bank is located on an adjustable bracket in
the water bath.
Start-Up
PLACING EQUIPMENT IN OPERATION
Before placing equipment in operation, verify that all
requirements for roof mounted Remote Condenser units
(if applicable) have been satisfied. Refer to the instructions
on installing the Remote Condenser. Verify proper supply
power to unit.
1. Fill the refrigeration unit water bath tank with water to
within 1/2" (13 mm) of the top of the overflow tube.
2. Open the manual water shut-off valve to the water
cooled condenser (if applicable). Refer to page 3-3 for
control programming sequence.
3. Press “Comp/Agit” to begin building an ice bank.
4. Ice will begin to form on the evaporator coils in
approximately 2 hours.
5. The refrigeration unit will build an ice bank in
approximately 4 to 6 hours.
6. If optional CO
2
/Water Control Panel has been installed
on the refrigeration unit, refer to the installation
instructions for operation and testing the circuits for
leaks.
7. The carbonation circuits “A” and “B,” as well as the
syrup circuits must be checked for leaks and possible
cross circuits before turning ON the water supply to
carbonator pumps.
8. Turn on main water supply. Set incoming regulator to
55 psi on the CO
2
/Water control panel. Once water is
supplied to the unit, air needs to be purged from the
carbonator tank. Do so by lifting press relief valve tab
until water comes out of relief valve.
9. Set bag-in-box syrup tank push pressure CO
2
regulator
to 60 psi.
PLACING THE SYRUP SYSTEM IN OPERATION
1. Open the CO
2
gas supply valve at CO
2
tanks or bulk
tank. Adjust the CO
2
pressure to 90 psi (6.2 bar).
2. Open relief valve on top of the carbonator tank for 4
seconds to bleed off air in tank.
3. Verify the water supply to unit is on.
4. Press the switch labeled “Carb A” (and “Carb B” if
applicable). Allow carbonator to run and cycle OFF.
5. Press the switch labeled “CIRC A” (and “CIRC B” if
applicable).
6. Activate all vales until a smooth, continuous flow or
carbonated water and non-carbonated water appear at
the valves.
7. Allow at least 1 hour before proceeding to calibration
instructions. You may complete the sanitizing
instructions during this period.
