This device is delivered in sturdy packaging in order to avoid damage during transport.
This packaging consists mainly of recyclable materials. We request that you dis-
pose of the packaging accordingly for recycling.
Installation
The device should be installed in accordance with the drawing on the first page of the
user manual. Any other installation position may result in serious damage to the device.
Installation should take place as close as possible to a cold water connection. The
product should be protected from the effects of frost (for example in caravans,
summer houses, etc.). Depending on the model, the device may be installed
above (OT-model) or under (UT-model) the worktop.
Frost
The device should be installed in a vertical position in a room
protected from frost and in the proximity of the water connec-
tions. In case the room cannot be protected against frost, the
device should not be installed in this room. Should the device
be installed in such a room, the device should be emptied be-
fore the frost danger will occur.
Connection to the water supply
Blue = cold water entry side (for filling)
Red = hot water exit side (hot water demand)
The device is designed for use in zero-pressure systems. This system allows water
to be drawn from a single discharge point. Never use a shut-off valve in the appli-
ance’s outlet.
The connection pipes must be installed as shown in the drawing.
A low-pressure tap fitting must be used for zero-pressure
installation.
The water supply pipe and water discharge pipe are marked (red for hot water,
blue for cold water). (See the assembly instructions for the tap fitting.)
If the mains water supply pressure exceeds 5 bars, a pres-
sure restrictor must be fitted in the feed pipe. At the spout of
the tap only a strainer (normally supplied with a low-pressure
tap) can be installed, whereas a normal aerator or restrictor is
prohibited.
