7HOW TO USE THE MACHINE
OPERATING ELEMENTS
➢STEAM FUNCTION
One steam lever « V » located on the left side of the panel is provided to allow:
The heating of liquids by spraying steam.
The milk foam production to create Cappuccino or Macchiato.
Turn the lever anti-clockwise: The steam goes-out from the steam outlet.
To stop the steam delivery = Turn the lever “clockwise”
Advises:
The liquid to be heated should preferably be placed in a deep container.
The tip of the steam wand outlet must be immersed in the liquid, without touching the bottom of the container.
The steam may also be used to sterilize and warm glasses.
After each use and absolutely after heating milk, always clean the stainless-steel steam nozzle and the outlet
nozzles with a damp cloth, removing all traces present.
A rinsing of the steam lance inner holes is to be done by a short pulse on the lever downwards to release a jet of
steam.

Edition 03/2022 - ACE –Technical documentation - page 14
SACOME, CONFIDENTIAL Document, it is forbidden to duplicate or communicate this document without previous authorization.
➢HOT WATER FUNCTION
One Hot water lever « E » located on the right side of the panel is provided for preparing tea, grog, etc.
Turn the lever clockwise:
The Hot water goes-out from the hot water outlet.
The Hot water goes out while the lever is not removed on the left.
To stop the Hot water delivery = Turn the lever “anticlockwise”
Be careful, not to be burnt by the pressure water spray.
For that, the valve is coupled to a cold-water mixing valve to adjust water T° for tea and avoids spitting hot
water.
➢FILTERS
The machine is equipped with two types of filters: 1 cup (9 G) and 2 cups (18 G)
Each filter is operating with its own holder-filter to produce respectively 1 cup or 2 cups of coffee.
Filters need to be unclogged and clean, so they need to be cleaned almost once a day with hot water, by being
removed from the holder filters.
Take care to remove all residual traces of coffee and ensure proper cleanliness of perforations in the bottom of
the filter.
➢FILTER-HOLDER
Never remove the filter-holder during operation of the group. The shutdown is controllable with coffee spouts:
they no longer eject liquid.
Be careful to always keep the filter-holder engaged in the group, emptied of coffee cake, to keep them warm.
In case of an extended stopping period, remove the filter-holder from the group, taking care to eject the used
grounds remain in the filter-holder.
Tighten the filter-holder until to be in contact with the seal, exceeding a little bit. The sealing is guaranteed.
Do not unnecessarily try to crush the seal by tightening the filter at the maximum of your possibilities. It may
damage the seal prematurely.
To empty the coffee filters used, turn the filter holder upside-down and lightly tap it on the edge of a wooden
box. Never strike it against metal or other hard objects.
➢DIGITAL MANOMETER M1 : BOILER PRESSURE
The boiler pressure is adjusted in factory between to 0,12 MPa. This value varies slightly around its nominal
temperature, due to the PID system which controls the heating.
NOTE: An over-heating thermostat cut the power on the heating element. In case of an abnormal high
temperature. The heating element is not anymore supplied.
➢DIGITAL MANOMETER M2: PUMP PRESSURE
The pump pressure is adjusted at 0,9 MPa in the factory. Value which allows the best extraction of coffee
flavors. A bypass system evacuates over-pressure on the pump.
Visualization of the presence of water network is done by consulting the gauge on M2 manometer.
