10–1. PRE-INFUSION
The settings entered on group head 1 (via
the first push-button panel) will be copied
automatically to all the other group
heads.
Our software allows configuring the dosage so
that the volumetrically controlled doses of coffee
is preceded by pre-infusion.
After time 1 (ON), coffee dispensing stops for time
2 (OFF) and then continues until the selected dose
has been dispensed completely.
If you press one of the volumetric controlled dose
buttons, the normal dispensing cycle is preceded
by a short timed jet of water to dampen the coffee
dose before actual dispensing takes place.
This function ensures the optimum use of the
coffee dose.
11. DISPENSING HOT WATER
11–1. MODELS WITH HOT WATER DISPENSING
BUTTON
Place a container under the hot water dispensing
tap (
13
), press the button (
15
) that will activate a
device that mixes the pre-set amount of hot water
from the boiler and cold water from the water
supply.
We recommend that you dispense steam
for a maximum of 60 seconds.
12. PREPARING OTHER DRINKS
12–1. MILK, CAPPUCCINO AND OTHER HOT
DRINKS
Before heating drinks, carefully dispense a
small amount of steam from the steam wand
(
11
) by turning the steam knob / lever (
14 -
20
)
anticlockwise to eliminate any condensation that
may have formed in the boiler.
Place the liquid to be prepared in a container,
immerse the steam wand (
11
) into the liquid
and slowly turn the steam knob / lever (
14 -
20
) anticlockwise. Then open the steam knob
completely to dispense a large quantity of steam
that will bring the liquid to boiling point. To
froth milk for a cappuccino, half fill a tall narrow
container with the milk to be prepared.
Immerse the steam wand (
11
) until it touches the
bottom of the container and bring the milk almost
to boiling.
Move the container up and down with the tap
open until you just touch the surface of the milk
for a few seconds, until the froth has formed. To
make a cappuccino, add the hot frothed milk to
the hot coffee that is already in the cup.
12–2. TEA, CAMOMILE TEA
Place a container under the hot water dispensing
tap (
13
), press the button (
15
) to dispense the
water and then add the bag/sachet of the drink to
prepare.
13. CLEANING AND MAINTENANCE
13–1. CLEANING THE STEAM WANDS
To avoid altering the taste of the drinks to be
heated and to prevent the holes at the end of
the steam nozzle from becoming clogged, we
recommend cleaning the nozzle thoroughly after
every use.
13–2. DAILY CLEANING
Rinse the filter baskets and filter-holders in boiling
water to prevent scale or remove coffee deposits
and clean the shower screens of the group heads.
14. WEEKLY CLEANING
14–1. CLEANING THE GROUP HEAD AND SPOUTS
Remove the filter holder from the group head.
Place the membrane provided into the filter, add
a spoonful of coffee machine cleaning powder
and insert the filter holder (
22
) into the group
head to be cleaned (
21
).
Use the group head control (
17
) to start
dispensing and stop delivery after approximately
4-5 seconds.
Start and stop delivery alternately for
approximately one minute to remove coffee and
limescale deposits.
Remove the membrane and start dispensing
several times in order to rinse the group head.
Dispense several cups to eliminate unpleasant
tastes from the spouts and the group head.
After hot water has remained in the pipes for
a long time, allow water to flow downwards to
remove any deposits.
14–2. CLEANING THE FILTERS AND FILTER
HOLDERS
Regularly check the holes in the filters in order to
remove any coffee deposits.
