-Connection
You will require minimum a stage-wire pressure regulator with 0.7 MPa (7 bar). Using tubing with an inner
diameter of 4 mm, connect the pressure regulator to the carbonator. Set the CO2-pressure to 0.50
– 0.55 MPa
(5.0 to 5.5 bar). The unit include a CO2-pressure switch to switch off the dispensing valves at a CO2-pressure
less than 0.35 MPa (3,5 bar).
The Triton 2500 and Triton 700 FF require up to 560 liters water/hour. The units require also a high demand of
CO2 which is more than a CORNELIUS regulator with provide and it may cause freezing up. In this case a dry
and clean product tank can be used as a buffer in the line from regulator to Triton.

Connecting Premix and Postmix Syrup
Connect one tube with an inner diameter of 6 mm to each device connection. Connect the tube end to the
correct cooling coil inputs of the cooler circuit carbonator.
4.4
Connecting Soda Water and Still Water
Connect the soda water to the forward and backward fittings at the Triton. The inside diameter of the tubes
should be 13 mm.
The still water has to be connected to the still water outlet of the Triton. The flow pressure is adjusted to 0.32
MPa (3.2 bar). If necessary, it can be adapted to the local requirements.
4.5
Power Supply of the Electric Valves
The Triton standard version is equipped with a transformer with 24 Volts~ 100 VA for the electric power supply
of the valves in the tower.
For the power supply of the valves these are connected to the connecting bus (X40 at the circuit diagram) at
the Tritons inner panel according to the circuit diagram.
In the case of insufficient CO
2
-pressure at the carbonator inlet, the power supply to the valves is switched off.
In addition to this a lamp, indicating low pressure, can be connected to the connecting bus according to the
circuit diagram.
For units with 3-pin level probes a complete emptying of the carbonator bowl is prevented by switching off the
power supply of the valves in time. The power supply is switched on automatically after the carbonator bawl
has been filled up again.
Caution:
A short circuit in the power supply to the valves caused a transformer switch off or a damage of the
level board.
4.6
Connection of Still Water Control
For still water, one switching cable (1 x 0.75 mm
2
) per still water tap must run from the soda circuit carbonator
to the still water tap. The electronic control system is actuated via this cable. An additional cable from one of
the still water valves is necessary.
Alternatively, there are some units which can be controlled by a pressure switch for the still water. It is
recommended to adjust the still water flow pressure to 0.32 MPa (3.2 bar) and the switching point of the
pressure switch to minimum 0.42 MPa (4.2 bar). If a different flow pressure is required the switching point of
the pressure switch must be set 0.1 MPa (1 bar) above the flow pressure.
Refer to the circuit diagram for the connection. The flow rate of the still water should be 170 ml in 4 to 5
seconds.
