7.9.1 Coffee Brewing
1. The coffee outlet elbow and baseplate are colour coded yellow and the belt is tan.
2. The chamber clamps down onto the base plate and filter, water and coffee is then
dispensed. After the brew time (set in program) has elapsed a 24v DC peristaltic
pump draws the coffee liquor through the filter and is pumped to a whipper
chamber where it can be whipped if required before being delivered into the cup.
3. The chamber now lifts and the second motor drives the filter belt and the waste is
scraped into the waste bucket.
7.9.2 Tea Brewing
1. The tea outlet elbow and baseplate are colour coded blue and the belt is white.
2. The chamber clamps down onto the base plate and filter, water and tea leaves are
then dispensed. Gravity draws the tea through the filter and it is delivered into the
cup.
3. The chamber now lifts and the second motor drives the filter belt and the waste is
scraped into the waste bucket.
7.10 Power Supply
1. The main power supply unit (PSU) provides power to the machine. It is mounted in
the top right hand side of the machine and can be accessed by removing the top
RH panel.
2. The PSU converts 230v AC to 24v DC to run the valves, whipper motors, ingredient
motors, brewers, etc. fitted to the machine. The solid state relay, mounted on the
PSU chassis, uses a 24v DC switching circuit to provide 230v AC for the heater
element.
3. A secondary PSU converts 230v AC to 12v DC to power the screen and associated
LEDs.
4. The Input/Output (I/O) board, mounted on the PSU chassis, utilises signals from
the main controller in order to operate valves, whipper motors, the dispense head
motor, ingredient motors, brewer motors, etc.
5. The PSU houses the fuses. These are as follows.

Heater, 12 amp (T) (ceramic) - Heater Tank

240v Auxiliary, 4 amp (glass)

240v Cold Unit, 4 amp (T) (glass) - if a fridge is fitted

24v Coin Mech, 4 amp (T) (glass) - if a Exec monetary system is fitted
Early machines had separate fuses for the Pressure Boiler (12A T) and also for the
PSU (4A T).
