Water connection
The Therme can be installed in already existing systems with a
single tap, as shown in fig. A, with a Truma mixing valve (part
no. 40020-00300 – not part of the scope of delivery) or as
shown in fig. B, with pre-selecting mixing tap(s).
All hose connections must be secured with hose clips
(also cold water)!
All connection fittings are designed for 10 mm hoses.
For fastening the hoses to the wall or floor we recommend
using the hose clips SC (6 – part no. 40712-01) which enable
frost-protected routing of water hoses on the hot air distribu-
tor pipes of the heater.
Installation of the Truma mixing valve
The Truma mixing valve is equipped with a backflow preventer
towards the pump. Only possible with fittings with electrical
switch.
When using other pre-mixing valves, always observe the
respective instructions!
When using several single-tap fittings, a pre-mixing valve
must be installed for each one respectively!
Fig. A
Drill a hole with dia. 16 mm in the vicinity of the tap (15), on a
flat surface of the wash basin, sink or vertical wall in front of it
always higher than the actual Therme, vertically align mixing
valve using the two nuts and fasten in such a way that the up-
per nut (7) is approximately level with the end of the thread.
Mount control knob (8), screw on and turn to the left, up to
the stop.

Apply marking on the wash basin in such a way that this is
level with the end of the red symbol on the control knob of the
mixing valve.
