Fat solvent Personal choice

Silicone grease Food-safe

1.4 Safety precautions

We recommend you consult this Service Manual of the machine before performing any mainte­nance work.
Observe all applicable standards relating to the repair of electrical appliances.

Always disconnect the power plug from the mains before beginning repair work.

Simply turning off the main machine power switch is not an adequate safety precaution.

This domestic appliance is rated as insulation class I.
On completion of the repair work, insulation and dielectric rigidity tests must be performed.

For IN WARRANTY repairs is mandatory to use the single components (not the assembly) avail-

able in the exploded views of the coffee machines or of the specifi c components. If you fi nd the

information “SEE THE EXPLODED VIEW E........” in the assembly description fi eld, it means that

the single components of the assembly are available in the other pages of the exploded view. It’s
possible to use the assembly only if there is a specifi c Symptom Cure that include this possibility or
when the single components are not available for the order.

2.2. Specifi cation for the measurement of the coffee products temperature.

The temperature is infl uenced by the fl ow from the dispenser and stratifi cation of temperatures in the
glass. In order to consider these phenomena and to introduce measures that allow comparisons in con­trolled conditions, below guidelines must be followed:

Conditions:

a) Water temperature in tank: 23°C (+/-2°C).

b) It must be used a plastic cup (see picture N°1).

c) It must be used a thermocouple thermometer (e.g. type K - see picture N°2).

d) The coffee machine is tested without any change of parameters or calibrations, which may
affect the temperature of products, so the measurement of temperature must be done with
machine in default factory setting.

Procedure:

1. The temperature must be measured in the cup, immediately after dispensing. Cup has to be
placed on a non-metal surface using a thermocouple thermometer.

2. The temperature in the cup is measured by immersing the probe of the thermometer up to
touch the bottom.The probe then must be moved in a circular motion for 5/6 rotations. At the
of the rotations, stop in the center of the cup.

3. The highest temperature measured during the rotations is the value we are searching for, and
that must be reported;

4. Test measurement: from end of dispensing to the end of rotations must be completed within 12
seconds.

Limits of acceptability

The acceptance limits are divided by features and products and are the following:

Espresso Coffee Italy Q.ty 25/40 gr.

Temperature of 1st product 69°C ≤ 85°C
Temperature of 2nd product 72°C ≤ 85°C

Coffee Q.ty 70/120 gr.

Temperature of 1st product 69°C ≤ 85°C
Temperature of 2nd product 72°C ≤ 85°C

Talea, Odea Giro

• The solenoid valve has several functions and these are described in the following para­graphs. A mechanical overpressure valve is integrated in the electrical valve which opens
at approx. 18 - 20 bar.

• When dispensing coffee and the hot water / steam valve is closed, the coffee valve opens
at approx. 4 bar and the water is pressed through the brewing unit.

• The overpressure valve in the steam pipe to the Milk Island protects the system against
damage caused by pressure, the steam state overpressure is fed back to the fresh water
tank.

• The multi-way valve opens selectively depending on the operating situation in the fl ow

direction (dispensing) or against the fl ow direction (pressure release).

TALEA / ODEA - LINE 04 FUNCTIONAL PRINCIPLES

Brewing unit pressure reduction:

Before the brewing unit moves to the home
position after a brewing process, the electric
valve opens and the overpressure in the brew­ing chamber is released and escapes into the
residual water tray.

Ventilation:

After the appliance is switched on, the electric
valve opens, the pump is activated and the
appliance is ventilated automatically.

Preheating the pipes:

If the coffee machine has not been used for
a while or after each heating-up phase, the
pump is activated during the grinding process.
The hot water enters via the pipes, the multi­way valve, and the water channel into the
residual water tray.

When coffee is dispensed:

The same applies for when coffee is dispensed,
only the brewing unit is positioned in the
brewing position and is docked to the pin.
