Service manual April 2017 Uber boiler
2.PRINCIPLE OF OPERATION
•
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 [Boost Mode] the hot water is circulated through the FONT (to reduce any
temperature loss)
▪
a second thermisor located in the FONT is now used to control the
temperature of the water and therefore ensure the accuracy of the
delivered water
▪
a specialised software algorithm
APLogic
TM
is used to control the
temperature /- 0.2ºC,
2.1.1 Simplified O peration:
1. The unit is preset to a Prime Temperature at the factory (this may be changed
by the user). This is the stand-by mode and the temperature is displayed on
the display panel as Tank Temp.
2. The user presses the Boost button and holds this button down until the desired
set temperature is displayed on the display panel.
3. The Uber Boiler will now ramp the tank temperature from the Prime setting up
to the Set Temp while recirculating the water through the Font.
4. When the set temperature is reached the user will rotate the Font Dial
counterclockwise to start the flow of water.
5. To select another set temperature the user should press the Prime button
–
return the unit to the Prime Mode
– and repeat step 2 to the new temperature.
6. If a user has several brews/volumes to dispense they should remain in boost
mode where possible, otherwise the tank will refill with cold water when you
return to Prime and will take approx 2min to heat each 1Litre of water. If you
have several brews in a row at different temperatures it is best practice to do
your colder brew first and then heat up while still in Boost, as you cannot cool
down in boost mode.
2.1.2 First Operation:
•
Check that all installation procedures have been carried out
•
Ensure water valve is on
•
Ensure Font Dispense Knob is in the Off position
•
Plug boiler into 13A socket and operate the Power Switch
– located on the bottom of
the boiler
•
See Photo 1 for location and name of each feature
•
The boiler will take in water to the middle level probe and commence heating. The
display will show : PRIME FILL and the TANK TEMP: will show the temperature of the
water in the tank.
•
Once the temperature reaches the set point, the boiler will continue filling the tank in
short bursts to maintain constant temperature. The display will show PRIME READY
at this stage and the BOOST button will be enabled.
•
Once the water level in the tank has reached the high level probe (full) the heater will
turn off and display will show PRIME READY FULL
•
The boiler is now ready for use
