The machine should only be connected to the power supply by qualified
personnel. The following safety instructions should be obeyed at all times:

Ensure that the electrical requirements stated on the TECHNICAL

SPECIFICATIONS (pages 7 - 8) match the specifications of the power
supply at the outlet.

Ensure that the domestic electrical supply where the machine is being
installed is rated for and able to provide the power required by the
machine. Insufficient power supply, wiring, grounding, or insulation can result
in overheating and possibility of fire.

The coffee machine must be connected to an earth grounded electrical

outet that complies with the regulations in force in the country of
installation.

Ensure that a circuit breaker engineered for the power consumption of the

machine is installed to protect the domestic electrical supply, as specified on
the ratings plate located under the drip tray.

Do not connect the machine to the domestic power supply via extension

cords, plug adapters, or shared outlets.

The manufacturer will not be held liable for damage to persons, animals or
property resulting from incorrect installation of the coffee machine.

DANGER!

If the power cable or plug is damaged, it must be replaced by the manufacturer, distributor, or
its approved service technician in order to avoid RISK OF SERIOUS INJURY OR DEATH!

Connect the machine according to the specification on the ratings plate located under the drip tray.

Connecting the machine to the domestic water supply must be performed by a qualified person.
Purge at least 20 liters of water from the domestic water supply before connecting the machine to it to flush out

any debris that may be in the plumbing sytem that would otherwise accumulate inside the boilers.

The domestic plumbing system should be fitted with a brass 3/8” NPT male pipe fitting and an in-line

shut-off valve. Connect the 180cm water inlet hose included with the machine to the domestic water
supply and tighten the line fittings with a wrench to 15 ft. lbs. / 20N-m.

Only use safe drinking water with a hardness rating between 5ºfH and 8ºfH (French hardness

degrees) or 20 to 32 ppm (parts per million as calcium). If the hardness value is below this limit,
corrosion of hydraulic components is likely. If the value is higher, lime-scaling inside the boiler will
occur. In both cases, the proper function of the machine and quality and taste of the coffee will be
negatively affected.

If necessary, connect the machine to a water softener to reduce water hardness using the flexible 55cm

hose included in the accessory box.

Connect one end of the corrugated drain tube to the drain cup in the machine, connect the other

end to the plumbing drainage system in the installation area.

Boiler pressure is directly controlled by water temperature (fig. 01).
This machine is fitted with a pressure gauge that displays the boiler pressure, if the machine is

equipped with a digital display it will also indicate water temperature.

Important:

Only use the hoses supplied with the machine. Never reuse damaged hoses.
Ensure that the drainage tube is not twisted and that it is below the level of the drain cup.

Open the machine’s water supply valve.
Turn on the main power switch.
Press a drink button at the control panel on each

group, wait until water comes out continuously from
each of them. This ensures that the heat exchangers
in the machine are being correctly filled.

Open the steam lever to release the air trapped in

the boiler.

The red lamp indicates that the boiler is heating. The

lamp switches off automatically when the machine
reaches operating temperature.

CLEANING AND MAINTENANCE

Important:

To keep the machine looking and working like new, you should always follow the cleaning

and care instructions provided in this manual.
Always turn off the main power switch when cleaning the exterior of the machine.
All external surfaces should be cleaned with a damp, lint-free cloth that will not scratch the

machine.
Do not use aggressive cleaning detergents, solvents or degreasers. These can damage the

surfaces, and plastic and rubber parts, and leave unwanted residue.

Important:

Each day, or 8 hours after dispensing the last coffee, the following cleaning tasks should be
performed to maintain the quality and performance of the water system:

Portafilter: Brew one espresso with the filter empty (around one minute) to flush it out

(dispose of this water).
Steam Wand: Position the wand over the drip tray and open the steam lever for one minute

to flush the wand.
Hot Water Outlet: Place a container under the water outlet and open the lever for 20

seconds (dispose of this water).

Rinse each of the brewing groups, shower plates, and portafilters with hot water for 15 seconds.

Clean the external surfaces of the machine with a damp cloth, paying special attention to the

stainless steel parts.

Clean the steam wand and the water tap. Be sure that the nozzles are not clogged or partially

blocked with milk or other residue. If it’s necessary to remove them for cleaning, be careful not to
deform or damage any of the components during removal.

Clean the dip tray and the stainless steel insert grid under running water with a brush.

Clean the drain cup by slowly pouring one liter of warm water into it to dissolve and remove the

coffee residue that accumulates inside the drain cup and hose.

Clean the brewing group and portafilter with professional cleaning powder (page 26).

water could cause scalding or serious injury. After cleaning has finished, wait about 3
seconds before removing the portafilter.

Important:

When the cleaning process is finished, remove the portafilter and run water through
the group again to rinse out any residue. Repeat the cleaning process this time without
cleaning powder to remove any remaining residue. Store the blind gasket in a convenient
location for future use.

Note:

Rinse the group and portafilter with hot water (using only the blind gasket and hot

water, no cleaning powder) each day.

Clean the group and portafilter with cleaning powder once a week.

Megacrem

Cleaning the gasket and shower plate

While making espresso, coffee grounds will naturally accumulate on the group’s sealing surface.
Allowing an excessive amount of grounds to build up can prevent the portafilter from properly sealing
to the group head. In extreme cases, such as leaving a used portafilter in the group head for several
days, water can even become blocked from passing through the shower plate.

To prevent these problems, perform the following cleaning procedures daily:

Install the blind basket into the portafilter without cleaning powder.
Place the portafilter loosely in the group head - do not close it fully.

Press the Continuous button .
Perform an opening-closing motion with the portafilter in place without closing it fully. Water will

flow over and around the portafilter, passing through the closing surface and washing out any coffee
residue. Be very careful to avoid splashes, as this water is very hot and can cause burns.

Press the Continuous button again to stop the water flow.

Remove the portafilter from the group head.
Clean the shower plate and group gasket with a soft brush to remove any coffee residue.

Shower plate

CLEANING AND MAINTENANCE

WARNING!

Take special care to avoid scalding when
performing this cleaning operation, as the hot
water used to clean the gasket will spill over
the sides of the portafilter.

WARNING!

Do not fully tighten the portafilter. If fully
tightened, high-pressure water may spray out
and cause scalding or serious injury.

Disposal of machine

CLEANING AND MAINTENANCE

STORAGE AND DISPOSAL OF MACHINE

Always remove and insert the portafilters

gently. Never use excessive force to try
to close the portafilter. If the portafilter
does not turn and lock into place without
excessive force this usually indicates that
there is too much coffee in the filter
basket.

Important:

Do not place wet cups directly on the
cup shelf. Allowing water to drip into
the machine can cause mechanical and
electrical damage.

Before storage be sure to:

Perform all weekly and periodic cleaning procedures described in this manual (see pages 16-20).

Disconnect and roll up the power cord (this should be performed by a qualified person).

Disconnect the machine’s water inlet hose from the domestic water supply and drain the boilers (this

should be performed by a qualified person).

Clean the drip tray and exterior of the machine to remove any coffee or other residue.

Cover / re-pack the machine in its original carton and store it in a dry place where it will not be

exposed to extreme temperatures or humidity.

When returning the machine to service after long-term storage, perform all weekly and periodic

cleaning procedures before use.

Disconnect and roll up the power cord (this should be performed by a qualified

person).

Disconnect the machine’s water inlet hose from the domestic water supply and

drain the boilers (this should be performed by a qualified person).

Pack up and ship/deliver the machine to a certified recycling center.
