2) STEAM BOILER

By  turning  the  main  switch  (part  1)  to

position  “1”,  the  automatic  fill  system

will  be  switched  on  which,  by  activating

the  solenoid  valve  and  the  motor  pump

(part 15), will fill the steam boiler up to a

predetermined level selected by adjusting

the probe inside the boiler itself.

N.B.

It may happen that the air inside the boiler 

builds up pressure (which may be detected 

through the pressure gauge - part 3, Fig 1, 

2 or 3) To resolve this, turn the machine 

off and bleed the air from the groups (see 

previous page for instructions).  Once you 

have  completed  these  operations,  turn 

the  main  switch  (part  1)  to  position  “2” 

and wait for the boilers to reach operating 

temperature  and  pressure  (which  takes 

from  20  to  35  minutes,  depending  on 

the  size  of  machine),  which  will  be 

subsequently  maintained  at  a  constant 

value automatically.

During this time, the pointer of the lower 

scale  on  the  pressure  gauge  (part  3,  fig. 

1  or  3;  or  part  4  fig.  2)  may  reach  as 

high  as  11-12  bar;  this  may  occur  any 

time  that,  while  activating  the  groups, 

the  motor  pump  forces  cold  water  into 

the  coffee  boiler  at  a  pressure  of  8-9 

bar and, simultaneously, the temperature 

controller  regulating  the  temperature  of 

the  boiler  itself  switches  on  the  heating 

elements  in  order  to  bring  the  water 

contained  in  such  boiler  up  to  operating 

temperature.  However,  in  this  case  it  is 

necessary  to  adjust  the  expansion  valve 

(Fig.  4,  part  19A)  in  such  a  way  that  the 

pressure may never exceed 12 bar.

Brewing after first installation

Once the first installation procedures are 

finished, before proceeding with brewing 

coffee, hot water and steam, please follow 

these steps:

- Engage  the  portafilters  by  inserting

them into each group, brew water through

each group for at least two minutes.

- Being  careful  to  avoid  burns,  turn  on

each steam wand for at least one minute.

- Turn  on  the  hot  water  valve  for  the

time  necessary  to  allow  the  following

quantities of water to be brewed:

At least 1 liter for a 1/2 group machine

At least 2 liters for a 3 group machine

At least 3 liters for a 4 group machine

For EE model - fig. 1

Take a portafilter and place some ground 

coffee  in  the  filter  itself:  the  suggested 

amounts  (in  grams)  to  use  are  laser-

marked  on  the  actual  filters.  Press 

down  on  the  ground  coffee  with  the 

supplied  tamper  and  engage  the  filter 

holder  in  the  group  and  then  press  the 

switch  (part  5)  thus  allowing  coffee  to 

be  brewed;  when  you  have  obtained 

your  desired  amount  of  coffee,  press 

the  switch  again  (part  5), at  which  point

the machine discharges the pressure built 

up  in  the  filter  holder.  The  holder  may 

then be removed to proceed with making 

another coffee, as required.

For PADDLE model  - fig. 2

Take a portafilter and place some ground 

coffee  in  the  filter  itself:  the  suggested 

amounts  (in  grams)  to  use  are  laser-

marked on the actual filters. Press down 

on  the  ground  coffee  with  the  supplied 

tamper and engage the portafilter in the 

group.  Move  the  paddle  handle  of  the 

COFFEE BREWING BuTTON (fig.1 part 5)

CAUTION

DO NOT REMOVE THE FILTER HOLDER WHILE 

RELATIVE GROUP IS BREWING HOT LIqUIDS. 

THE COFFEE BOILER CONTAINS WATER AT 

ELEVATED TEMPERATURE.  WATER 

TEMPERATURE OVER 125°F / 52°C CAN CAUSE 

SEVERE BURNS INSTANTLY OR DEATH FROM 

SCALDING.
