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 prod-
uct 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 work top.
Frost
If there is the risk of frost in a room, the device should not
be installed in this room. If, despite this advice, the device is
installed in a room where there is a risk of frost, the device
should be emptied before the risk arises.
Connection to the water supply
(Illustration 1.)
K = cold water entry side (for filling) blue.
W = hot water exit side (hot water demand) red.
The device is designed for use in non-pressure systems. This system allows water to be
drawn from a single discharge point. Never use a shut-off valve in the appliance’s outlet.
The connection pipes must be installed as shown in the drawing.
A low-pressure tap fitting must be used for non-
pressure installation.
It is important you are absolutely certain that the
tap you want to connect concerns a low pressure
tap. If any doubt, always consult your installer.
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 (supplied with tap) can be in-
stalled, whereas a normal aerator or restrictor is prohibited.
Use of the latter, or usage of a tap that is not meant
for low pressure installations (e.g. garden hose),
may cause pressure build-up in the device that
might lead to damage and thereby void the war-
ranty!
