La Marzocco MAN.1O.MULTI Mode D'emploi page 6

General description
The models AV, EE and PADDLE are built
in the 1, 2, 3 and 4 group versions and are
essentially composed of the following parts:
1. Water boiler (produces steam and hot
water);
2. Coffee ("saturation") boiler;
3. Brewing groups;
4. Exterior;
5. Motor pump;
Description of the various parts
1. Steam Boiler
The steam boiler consists of a cylindrical
tank, of varying length according to the
number of coffee groups, which is made
of stainless steel. Each unit is subjected
to a hydraulic test, at a pressure of 3
bar, and has an operating pressure of 1.5
bar. In the following, you will find a list
of effective volumes and standard power
ratings according to the number of groups
installed:
1 group 3.5 litres 1300 Watts
2 groups 7 litres 2000 Watts
3 groups 11 litres 3000 Watts
4 groups 14.5 litres 3800 Watts
Higher powered heating elements are
available for steam boilers in some markets.
Covers are installed at either end of the
cylindrical tank and on one of them there
is a housing for the water heating and
vapourizing electrical elements, which
allow reaching operating pressure within
25' approximately. Operating pressure is
5
maintained by a pressure switch. The water
boiler has various fittings used for safety
devices, for supplying hot water and steam,
and for the power supply.
2. Coffee Boiler
The coffee boiler is subjected to a hydraulic
test, at a pressure of 16 bar, and has an
operating pressure of 9 bar. In the following,
you will find a list of effective volumes and
power ratings according to the number of
groups installed:
1 group 1.8 litres 1000 Watts
2 groups 3.4 litres 1400 Watts
3 groups 5.0 litres 1600
Watts
4 groups 3.4 + 3.4 litres
1400 +1400 Watts
(2boilers installed)
It consists of a cylindrical tank, of varying
length according to the number of coffee
groups, which is made of stainless steel.
Covers are installed at either end of the
cylindrical tank and on one of them there
is a housing for the water heating and
vapourizing electrical elements, regulated
by a precision PID Controller with a dT of
± 0.5°C which keeps the water temperature
constant. This temperature can be adjusted
to reach optimal temperature according to
the type of coffee blend being used. The
groups are welded to the boiler.
3. Brewing Groups
The brew groups are made of stainless steel,
in which you engage the portafilter used to
hold the ground coffee; the espresso flows
from the group, through a spout, into the
cup(s) after the brewing button has been
pressed.
4. Exterior
The exterior consists of painted and
stainless sheet steel panels. To provide
good aesthetics, to optimize ergonometrics
for the operator and to reduce the chance of
damage to a minimum.
5. Motor Pump
The rotary vane pump, is installed on the
or 1900 water supply tubing and is set up to operate
anytime the coffee groups are activated,
and through an autofill system whenever
the water boiler needs to be replenished.
WARNING
THE COFFEE BOILER AND STEAM BOILER CONTAIN
WATER AT ELEVATED TEMPERATURE. WATER TEMPER-
ATURE OVER 125°F/52°C CAN CAUSE SEVERE BURNS
INSTANTLY OR DEATH FROM SCALDING (COFFEE
BOILER 200°F/93.3°C-STEAM BOILER 260°F /127°C)
