Marco Beverage Systems Ltd. INSTRUCTIONS FOR MODEL Revision 9 Mar 2010 Uber Boiler P/N: 1000680 Uber Boiler 6L 2.8kW P/N: 1000681 Uber Boiler 2L 2.8kW MARCO is an ISO9001:2000 Registered Company. Water pressure : 5 - 50 psi (min.-max.)35 - 345 kPa (min.-max.) Marco Beverage Systems Limited.
UNIT INSTALLATION INFORMATION SAFETY: Risk of scalding. Beware of accidentally operating the water drawoff dial or push buttons especially when cleaning. If the dial is left in the ON position (shown later) then pressing boost will cause water to flow immediately from the font.

Connect right-angled tailpiece of the hose to the inlet valve of the boiler (again 3/4" BSP). Make sure the sealing washer is fitted here also. Turn on water and check for leaks. CLEANING: The exterior of these machines may be cleaned with a damp cloth and a light detergent.
COUNTER CUTOUT: NEVER lift or lower the unit by holding the font!–use the upper wide tile or lift from the base. The unit requires a counter thick enough to support the weight of the machine when full, when full it could be up to 30kg in total. Never overload the scale platform with a force greater than 9kg.
Principle of Operation of the Uber Boiler The Uber Boiler is designed to be a highly accurate hot water delivery system. This temperature accuracy is achieved by several features; o In stand-by the water is maintained at a set temperature [ Prime Mode ] this is controlled via a thermistor in the tank, o in the Boost Mode the hot water is circulated through the FONT (to reduce any temperature loss)

Once the water level in the tank has reached the high level probe (full) the heater will operate and it will take approximately 20-25 minutes to reach the PRIME temperature. On the display : PRIME HEAT Once the PRIME temperature has been reached the display will indicate : PRIME READY The boiler is now ready for use Use of the Time and Weigh Features:...
UNDERSTANDING THE DISPLAY AND CONTROLS: The Display screen contains 4 Lines of information 1. First line on the display shows status message: Status Description Tank is filling, not heating until reaches the top level probe. PRIME FILL Boost button disabled. Tank is heating, not filling until temperature in the tank reaches PRIME HEAT “Prime temp”.

2. The second line shows the live readout of: Tank temperature in PRIME mode, Font temperature in BOOST mode. 3. Third line shows the timer Clicking TIMER button turns on and off timer clock. Pressing it for longer than 2 seconds resets it and turns it off. 4.
MODES OF OPERATION The uber Boiler has 2 modes of operation: 1 PRIME Mode 2 BOOST Mode, this may be operated in Manual Boost or Auto Boost mode. PRIME MODE After turning on or pressing PRIME button the machine goes into Prime Mode. This is a stand-by mode when the water is prepared for final dispense.

Manual Boost Mode In Manual Boost Mode the heater is controlled manually by BOOST button. If the temperature read by any of the sensors (tank or font) is higher than the Max temp the heater will go off even if the BOOST button is pressed. This mode is turned on by setting Delta value to 0.0 in Calibration Mode.

Calibration Options their Description and Default values. Screen view Description Default Options 1 - 9 value Sets offset value for tank temperature sensor. The offset is the difference between absolute temperature and a measured one. It is factory set using calibrated instruments. TEMP shows live readout from tank sensor with the applied offset.

Sets BOOST mode time-out. Timer starts at the beginning of the BOOST mode. Machine goes back 06:00 to PRIME mode after that time to avoid unit being left in Boost Mode for too long. Calibrates weighing scale. 1kg weight is needed. Do NOT press any of the right hand side buttons if you don’t have any reference weight! TIMER button sets scale to zero;...
