Hot Water - Sanremo ROMA TCS SED Instruction Booklet

ENGLISH
Scale deposits cause an increase of torque, occasional seizure of the pump or a reduction of operating pressure because the pressure relief valve
cannot work properly.
To minimize this problem Fluid-o-Tech suggest to use pumps with flow rate matching the hydraulic circuit features.
In some circuits it is advisable to periodically remove scale with a chemical treatment.
Before using the appliance, check that:
- the plug is inserted properly into the mains power outlet;
- the filling hose is correctly connected to the mains outlet and that the water supply is open. Also check for leaks;
- The drain hose is positioned according to the previous instructions and fastened with a hose clip.
With the steam tap (B) open, place the ON/OFF switch (D) in position 1 and wait for the water in the boiler to reach the maximum level established
by the electronic control unit. If the boiler does not fill within the time-out set (90 secs), the pump stops and the LEDs on the keypads start flashing.
If this occurs, place the main switch (D) in the 0 position, then back to 1 to finish filling the boiler.
Place the main switch (D) in position 2. This activates the electric elements which start heating the water.
Wait for steam to be discharged from the steam nozzle (B), then close the tap and check that the pressure indicated on the boiler pressure gauge is
steady at about 0.8:1 bars. If this is not the case, adjust the boiler temperature. See 3D5 MAESTRO DE LUX control unit programming.
Ensure that the boiler pressure gauge indicates a pressure of 0.5:1 bar.
Press the button (M6) to dispense hot water and press again to stop.
Pay the utmost attention in order to prevent scald burns.
There are two steam nozzles at the sides of the work surface. These are retractable and swivelling as they are fitted with a ball joint. To deliver
steam, turn the knobs (B) anticlockwise. Take great care to avoid burns.
Insert the filter holder (E) into the group head (F) turning the filter holder counter-clockwise. Using the keypad (M) select the caption corresponding
to the required type of coffee:
M1=One strong/normal coffee.
M2=One normal/weak coffee.
M3=Two strong/normal coffees.
M4=Two normal/weak coffees.
M5=Key for electronic programming or continual manual dispensing.
a) To access this phase keep the button M5 on the first pushbutton panel on the left pressed for over 5 seconds. The indicator lights of the buttons
M5 start to blink continuously. Select the caption corresponding to the amount required and press to dispense. The indicator light of button
M5 and that of the selected caption remain lit. When the required amount has been dispensed, press the selected dispensing button again so
that the control unit stores the data. Repeat the above procedure for all 4 dispensing buttons on the pushbutton panel. A dispensed quantity
may also be set for the hot water button (M6) by repeating the above procedure. Upon completion of the procedure, the remaining groups will
automatically use the stored quantity. The other groups may, however, be programmed independently by repeating the same procedure as
above after having programmed the first group on the left.
b) There are 2 safety systems inside the control unit designed to protect the electronic system and the various parts of the appliance. If, upon
pressing a dispensing button, the corresponding indicator light starts blinking, this indicates a malfunction in the electronic system or lack of
water. For safety reasons, the dispensing of water stops after 4 minutes and in any case after 4 litres of water.
c) The ROMA electronics also offers the possibility of reproducing the pre-brewing effect by wetting the coffee for 0.6 seconds and then stopping
the subsequent brewing from starting for 1.2 seconds. This optional is only applicable for single shots of coffee.
Filter:
after having dispensed the last cup of coffee, the filter and filter holder must be washed with water. If they are damaged, worn or clogged,
they should be replaced.
Drip tray and grid:
coffee ground discharge tray to avoid coffee ground fermentation and related smell.
Water softener:
the softener should be periodically regenerated according to the manufacturer's directions given in the instruction
booklet.
External housing:
use detergents that do not contain abrasive powders or solvents and do not use steel wool.
WARNINGS:
when using the appliance it is recommended that the various instruments be kept under control, checking that they are in the
previously indicated normal working conditions.
