3.5.1 Power supply
Information about electrical connections is available on the machine’s wiring dia-
gram which is provided on delivery. Store the diagrams in the plastic pocket, lo-
cated in the electrical cabinet, even after installation.
• The machine is designed for quick electrical installation.
• The machine must be connected to a lockable power switch. This should
be placed on a wall, well-protected from water and from the steam which
escapes when the machine is opened.
• The machine is equipped with a phase sequence detector. The machine
will not start if the phase sequence is incorrect. If the phase sequence is
incorrect, the display will show POWER SUPPLY FAILURE CHECK
EMERGENCY STOP
It is important that the electrical connection is checked so that it is certain that the
live and neutral wires are correctly connected and not swapped over. It is also im-
portant to check at the same time that the earthing system connection is correct
and sufficient so that the machine’s electrical and personal security system is not
compromised.
The connection in the electrical cabinet is at (3). After completing the installation,
switch on the power switch and all circuit breakers.
3.5.2 Water connections, regardless of any options
• A shut-off cock must be installed on the incoming lines.
• It is important that the water supply has sufficient pressure to ensure the
correct flow of water to the machine. The required pressure can be found
in the TECHNICAL SPECIFICATIONS. If the water pressure is too low, a
booster pump must be fitted.
• In cases where the machine is fitted with a “Break Tank”, the connection is
fitted with a filter and non-return valve.
Connect the cold and hot water pipes according to the labels by the connection
points (1, 2). If the machine is connected with a hose, this should be steel braided
and have an internal diameter of at least 12 mm.
The hot water connection is fitted with a filter. The cold water connection is fitted
with a filter, non-return valve and vacuum valve. The connections have an internal
thread.
3.5.3 Ventilation
The machine has a heat recovery unit connected to an exhaust fan to reduce the
amount of steam released. Extractor fans for extracting steam can be installed
above the infeed and outfeed openings, as well as above the area of the machine
where steam is emitted from the heat recovery unit.
If a hood is fitted over the machine, it must cover both the infeed and the outfeed.
The front of the hood must be positioned at least 500 mm in front of the machine
to allow access for service and repairs.
