The hot water flow is operated by a push-button and can be time adjusted to your needs. Hot water
from the boiler is mixed with some cold to deliver non-spattering water of the correct temperature to
prepare “Americanos”.
All parts in the Mirage which spill water or steam in whatever circumstances are connected to the
drain pipe on the back of the drip-tray. The group valves, expansion valve, pressure safety valve and
anti-vacuum valve will thus not leak any water on your counter
or the Mirage’s electronics or blow
steam into your working space.
These drains have a second benefit. For example: whenever a dirt particle in the boiler fill valve
prevents it from closing, the boiler will keep filling. Such a malfunction will not be detected by the
Mirages’ computer and continues even when the machine is turned off. During opening hours you
might notice the malfunction in time. However, if it happens at the end of the day, water level in the
boiler will slowly rise until it reaches the safety valve. Since opening pressure of the safety valve is
probably lower than water mains pressure, the safety valve will be pushed open. The drain on the
safety valve prevents your workspace from being slowly flooded.
The Mirage is also equipped with an easily operated cleaning program which pressurises and de-
pressurises all groups simultaneously 8 times in a row.
The wide drain tray can be moved stepless up and down to accept any size of cup.
The elevated position of the body makes cleaning underneath the machine easy. Slightly down-
sloping handles on the filter holders ensure an ergon
omically better position of the barista’s wrist.
An optional pre-infusion system can be mounted on the Mirage. This
“soft-start” mechanism
(incorporating a progressive pre-infusion cylinder) absorbs pump pressure such that it increases
gradually to 3 Bar which ensures pre-wetting and swelling of the coffee grinds before extraction starts.
As an option, one or both steam valves can be switched on and off by foot for fast and efficient milk
steaming. Since the manual steam valves remain fully operable the steam flow can be adjusted to
your liking.
Notice
Filled with water, a Mirage espresso machine has a large mass and produces heat. Space in the
immediate surrounding should be available for coffee grinder, knock-box, tamper and other
accessories. The pump and water treatment (not included) should be placed in the proximity of the
machine. Water supply and discharge, as well as an AC socket with earth connection is needed. The
location of your Mirage should account for these.
