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 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 con-
sult 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 pressure re-
strictor must be fitted in the feed pipe. At the spout of the tap only a
strainer (supplied with tap) can be installed, whereas a normal aera-
tor or restrictor is prohibited.
Use of the latter, or usage of a tap that is not meant for low pres-
sure installations (e.g. garden hose), may cause pressure build-up
in the device that might lead to damage and thereby void the
warranty!
