Water Connection; Installation Of The Truma Mixing Valve; Routing Water Pipes With The Truma Mixing Valve - Truma E921003 Instrucciones De Montaje

If it is intended that both hot water connection nozzles
should be fitted, the venting valve (1) can also be con-
nected by means of a T-piece (fig. C: 5 – max. hose length
between connec tion nozzles and bleeding valve 40 cm).

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.
Using the hose clips SC (6; part no. 40712-01 – not
included in scope of delivery) it is possible to route the
water hoses on the hot air pipes, providing protection against
frost.
Clamp the hose clips under the clips of the hot air pipes.
They can also be used for fastening the water hoses to the
wall or floor.

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.
