ZIRCON
INSTALLATION
Water connection
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 system 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.
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.
Pressure and temperature
B
oiler 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.

CLEANING AND MAINTENANCE
ZIRCON
Coffee machine cleaning
Important:
T
o 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).
Daily cleaning
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.
Weekly cleaning
Clean the brewing group and portafilter with professional cleaning powder (page 26).

Cleaning the Brewing group and Portafilter
WARNING!
Never try to remove the portafilter while the group is performing the cleaning operation,
as the pressurized hot water could cause scalding or serious injury. After cleaning has
finished, wait at least 3 seconds before removing the portafilter.
Unlock and remove the portafilter from the group head.
Place the cleaning membrane in the filter basket.
Fill the filter basket with professional cleaning detergent (7gr. for a single espresso portafilter, 14gr. for double espresso portafilter). Detergent is available from your distributor as Part # 1104162.
Lock the portafilter into the group head.
To activate the cleaning and descaling program:
1.) Turn off the machine at the main switch.
2.) Press and hold down the 2 Short Espressos button
on the control panel of the group requiring cleaning. Without releasing the button, turn on the machine. Auto-cleaning will start automatically.
3.) Release the button. The machine will clean, flush, and rinse itself.
4.) If any residual powder is present, simply rinse the portafilter under clean water and press the Continuous Dispensing
button and allow it to flow for 15 seconds with no portafilter in place.
OR, simply repeat steps 1 through 3 with using any detergent to rinse the group and portafilter.
5.) When all cleaning/descaling is complete, remove the blind gasket and store it in a secure place.
Important:
Boiler descaling is only to be performed by a qualified technician, and frequency will depend
on local water conditions and frequency of machine use. Contact your distributor for boiler
descaling questions and technical assistance.

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

CLEANING AND MAINTENANCE
Additional handling of the 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.
