Safety notes
2.1 Proper use
The AT Excellence reverse osmosis device treats (demineralises)
mains water (max. 35 °C) for subsequent use in commercial
warewashers. The device reduces the overall salt content of the
mains water.
The device may be used only in conjunction with a commercial
warewasher.
The device is a technical device for commercial use and is not
intended for private use.
2.2 Improper use
The treated water may not be used as drinking water.
This device is not intended for use by per-
sons (including children) with limited physi-
cal, sensory or mental capabilities or who
do not have the required experience with
and knowledge of this device. Such persons
must either be instructed by a supervisor
who is responsible for their safety or must
be supervised during the operation of the
device.
Winterhalter Gastronom GmbH assumes no liability or warranty in
the event that the device is used improperly.

the device; always call a qualified electrician.
Disconnect the water supply immediately if the device begins to
leak. Disconnect and isolate the device from power supply and
close the water stop cock.
In case of danger, switch off the device immediately. Pull out the
mains plug. Only then is the device free of voltage.
Never insert or pull out the mains plug with wet hands.

Requirements
Mains water
The quality of the mains water must conform to the requirements of
your water authority. In addition, threshold limits must be adhered
to (
Water connection and electrical supply
To maintain the membranes, automatic flushing takes place every
two hours in stand-by mode. For this reason, the device must remain
permanently switched on and the electricity and water supply must
be connected.
Warewasher connected to the device
The warewasher must fulfil the requirements of DIN EN 1717 or
respectively DIN EN 61770.
All components of the warewasher that come into contact with
water must be suitable for osmosis water. Use of non-ferrous met-
als is not permitted. Only synthetic components and stainless steel
components may be used.
The device should primarily be used in combination with a com-
mercial warewasher with a pressure-independent boiler. Operation
on warewashers with pressure boilers in conjunction with a pres-
sure expansion vessel is possible. The yield is reduced, however,
and the fill time of the warewasher is extended.
