72 Part Number STH12 9/10
Start-up (Non-ERC)
1. Fill the refrigeration unit water bath tank with
water to within 1/2" (1.27 cm) of the top of the
overflow tube.
2. Open the manual water shut-off valve to the water
cooled condenser (if applicable).
3. Turn ON the rocker switch labeled “Refrigeration”
to begin building an ice bank.
4. Turn ON the rocker switch labeled “Agitator”.
NOTE: On TS units 3 & 4 are combined into 1 switch.
5. Ice will begin to form on the evaporator coils in
approximately 2 hours.
6. The refrigeration unit will build an ice bank in
approximately 4 to 6 hours.
7. 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.
8. 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.
9. Turn on main water supply. Set incoming
regulator to 55 psi on the CO
2
panel; 25 psi for the
Model 11M root beer system’s internal regulator
(must be lower than CO
2
supply pressure). 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.
10. Turn on main CO
2
supply. Set regulator initially to
90 – 100 psi. For the Model 11 Root Beer system,
set regulator initially to 26 psi; it can be raised
incrementally to 30 psi if there is excessive
foaming.
11. Set bag-in-box syrup tank push pressure CO
2
regulator to 65 – 70 psi. For the Model 11 Root
Beer system, set push pressure CO
2
regulator to
35 – 40 psi.
