DESCRIPTION OF THE APPLIANCE

The main functions of the machine, and its relative parts, are described below, with a view

to ensuring its maximum performance.

COFFEE DISPENSING (K-Kwts-S-M-C-B)

Independent dispensing groups with predosed or manual selections.

Filterholders for one or two cups.

DISPENSING OF HOT WATER AND STEAM (K-Kwts-S-M-C-B)

The machine has one or two steam wands and a hot water dispenser which allows the use

of large milk or water containers thus guaranteeing good general ergonomics.

ELIMINATION OF CALCIUM AND MAGNESIUM SALTS FROM THE WATER

(K-S-M-C-B)

This enables the elimination of scale deposits in the machine thanks to a water softener

that softens the water, eliminating the calcium and magnesium salts contained in it.

The water softener is not incorporated in the machine and has an independent manual

or automatic function.

ELIMINATION OF CALCIUM AND MAGNESIUM SALTS FROM THE WATER

(Kwts)

This enables scale deposits to be removed from the machine.

It consists of an ion exchange resin water softener, completely and automatically managed

by the machine.

AUTOMATIC REGENERATION OF THE WATER SOFTENER RESINS (Kwts)

When the resins in the water softener are used up, all the operator has to do, on receiving

the automatic prompt from the machine, is to load the salt.

During regeneration, the system automatically excludes the water treatment circuit from

the machine water supply, allowing the machine to operate without it.

ELIMINATION OF CHLORINE AND ORGANIC COMPOUNDS FROM THE

WATER (Kwts)

Removes the bad taste and deposits caused by the Chlorine and eliminates bacteria, making

the water purer.

It consists of a silver-loaded activated carbon cartridge ﬁ tted inside the machine,

at the water supply inlet.

The system signals the exhaustion of the cartridge in relation to the volume of water that

it has treated and excludes it automatically from the machine water supply circuit, allowing

the machine to continue operating without it.

CONTROL OF WATER LEVEL IN THE BOILER (K-Kwts-S-M-C-B)

This is done by means of a level probe which controls the water level in the boiler,

topping it up automatically when required.

57

CONTROL OF WATER TEMPERATURE IN THE BOILER (K-Kwts-S-M-C-B)

This keeps the temperature of the coffees constant as opposed to the temperature

and the pressure of the steam.

Consequently, it also controls the pressure in the boiler.

STABILIZING THE BREWING TEMPERATURE (K-Kwts-S-M-C-B)

Each dispensing group has a heating circuit for brewing water that functions with

a heat exchanger.

This circuit ensures that the dispensing group remains at a constant and optimal temperature

even when it is not being used thanks to the effect of the natural circulation of hot water

ﬂ owing through the circuit itself.

MEASURING THE BREWING PRESSURE (K-S-M-C-B)

This enables the manual regulation of pump pressure during coffee dispensing.

The pressure is displayed on the gauge clearly visible in the working area.

On the K model, the gauge is ﬁ tted inside the machine.

MEASURING THE BREWING PRESSURE (Kwts)

Through the reading of the display, this enables the manual regulation of pump pressure

during coffee dispensing.

MEASURING THE WATER SUPPLY PRESSURE (Kwts)

Enables automatic protection in the event of a water supply stoppage.

PROTECTION OF THE HEATING ELEMENTS (K-Kwts-S-M-C-B)

This consists of a safety level probe that triggers the cutting off of power to

the heating elements.

Resetting takes place through Basic Programming.

See chapter “G – USE”.

PROTECTION FROM OVERHEATING (K-Kwts-S-M-C-B)

In each of following cases:

- Excessive duration of heating

- Exceeding of maximum allowable temperature value, the heating elements are disabled

and a major fault is reported.

UPPER CUP TRAY (S-M-C-B)

These models are equipped with cup heater trays with the capacity to contain a large

number of cups on various levels and to keep them warm in order to guarantee an excellent

cup of coffee.

The heat is generated by a natural ﬂ ow of hot air from the inside of the machine.
