Hot Water Dispensing; Checking The Water Level In Steam Boiler; Checking The Pressure Of The Steam Boiler; Coffee Dispensing - ELEKTRA SPF Instruction Manual

6 HOT WATER DISPENSING

The machine has one hot water valve equipped with a swivel wand which allows the use
of large water containers and guaranteeing good general ergonomics.
The valve, is operated by a joy-stick with movement in any direction.

CHECKING THE WATER LEVEL IN STEAM BOILER

This is done by means of a level probe which controls the water level in the boiler,
topping it up automatically when required.
8

CHECKING THE PRESSURE OF THE STEAM BOILER

The water pressure in the boiler is controlled by a pressure switch that controls the
switching ON of the electric heating elements. Thus, it determines the temperature control
of the water in the boiler too.

COFFEE DISPENSING

The dispensing control is semi-automatic and works by means of an ergonomic lever
located next to the dispensing unit.
The brew group is equipped with a dedicated boiler, equipped with a heating resistance of
the infusion water and control of its temperature by means of a precision sensor.
The water reaches the brew group after being passed through a preheater, so as to mini-
mize the temperature difference necessary to maintain the desired temperature and also
minimize the reaction times to the regulation.
This system, together with the construction features with low inertia and high thermal
insulation, allows to keep the infusion water temperature in real time equal to the value set
with high precision and high speed of physical variation.
You can adjust the coffee temperature in a range of values from 70 ° C to 95 ° C.

10 PRE-INFUSION

Coffee dispensing, even if manually controlled, takes place thanks to the two-phase
automatic cycle:
- Pre-infusion
- Infusion
While the infusion is carried out normally using the pump pressure of about 8/9 bar, the
pre-infusion is performed with the only pressure of the water supply or with the residual
pressure present after the previous dispensing.
In this way, the coffee powder slowly soaks in hot water and is best prepared for the
subsequent extraction by pressure.

11 NIGHT CYCLE

By setting a daily schedule, the machine enters a partial operating mode in which the
boiler and unit heating is switched OFF.
At the end of this time, the machine resumes its full operating mode.
