Installation
3. Reverse osmosis system
A reverse osmosis system must be used if the chloride concentration exceeds 60 mg/l. This is very cru-
cial in order to avoid corrosion.
4. Water softener
If a high level of scale build-up is experienced, a water softener is needed. H+ Ion Exchanger or
Kleensteam are recommended systems. Sodium ion exchangers must not be used because of problems
caused by high salt content.
5.5. Ventilation
The heat and steam load of the kettle must be taken into account in the kitchen’s ventilation plan. A ven-
tilation hood must be installed above the kettle, because plenty of steam is released when the kettle lid
is opened. When dimensioning the ventilation hood, the space requirement for opening the lid must be
taken into account (see installation drawing).
5.6. Other installations
In case the combi-kettle being installed is connected to a kitchen power management system the con-
nection points are shown in the electric wiring diagram.
5.7. Procedures after installation
5.7.1. Adjusting the tilting
Before refi tting the cover plates on the combi-kettle control panel, you have to check and, when needed,
adjust the operation of tilting.
On hydraulically tilted Proveno 200, 300 and 400 combi-kettles, fi rst check the rotation direction of the
hydraulic pump. The correct rotation direction is anticlockwise viewed from the motor’s cooling fan end.
If the rotation direction is wrong, two phases of the supply cable coming to the mains switch have to
be exchanged.
Next you have to ensure that the kettle is horizontal when it is in the cooking position. Before that make
sure that the combi-kettle’s control pillar has been installed horizontally. Checking is done as follows:
• First tilt the kettle at least half-way and after that press the tilting reverse button as long as the kettle
stops in the cooking position.
• Check the kettle’s horizontal by the upper rim of the kettle.
If the kettle is not horizontal, the position of the mounting plate of the tilting limit switches must be
adjusted as follows:
• Tilt the kettle at least half-way.
• Loosen the locking nut for adjustment (5) and the fi xing nut for the limit switch plate (6) so that the
limit switch plate (1) can be moved, but after moving stays in the new point.
• If the combi-kettle in its cooking position is tilted too much towards the spout, turn the limit switch
plate (1) slightly downwards. In case the kettle in its cooking position is tilted too much backwards,
turn the limit switch plate (1) slightly upwards
• Tighten the locking nut (5) slightly after adjustment, press the tilting reverse button until the kettle
tilting stops and check the kettle’s horizontal again by the upper rim of the kettle.
• Tighten both the fi xing nut (6) and the locking nut (5), if the combi-kettle is horizontal in its cooking
position. Otherwise, repeat the adjustment measures.
