Installation Instructions; Water Supply; Choice Of Location; Installation Of The Therme - Truma Therme Einbauanweisungen

Installation instructions

Installation and repair are only to be carried out by an
expert!
The Therme is designed for pressure-free operation. In
order to enable the pressure, which builds up during the
heating up procedure, to escape, there is to be no non-return
valve installed in the cold water supply between Therme and
submergible pump.
When connecting to a central water supply (city mains) or
when using stronger pumps, a pressure reduction valve must
always be installed to prevent that pressures above 1.2 bar
develop in the Therme. In addition, a safety/drain valve
(accessory, part no. 70141-10) must be installed into the cold
water supply line.
Only tap fittings with electrical switch are to be used!

Water supply

When installing a water supply into the vehicle, please ensure
that there is an adequate distance between the water hoses
and the heat source (e.g. heater, warm air duct).
A water hose may only be fitted at a clearance of 1.5 m to the
heater on the warm air duct. The Truma hose clip SC (part no.
40712-01) can be used if this distance is observed. In the case
of parallel installations, e.g. openings through a wall, a spacer
element should also be attached (e.g. insulation) to prevent
contact.

Choice of location

Select an installation location near the heater (not in the
installation space behind the heater).
If there are two bleeding points (fig. B), please select an in-
stallation location where the hot water pipes can be as short
as possible.

Installation of the Therme

Place the Therme on the floor on its mounting supports and
bolt down into place.
Insert hot air hoses at both sides. If no hot air supply is to be
connected, seal both air connection fittings using the VD seal-
ing cap (part no. 40353-01 – not included in scope of delivery).

Fitting the draining and venting valve

Draining and venting valves must be fitted in the immediate
proximity of the device (max. hose length 40 cm), at a point
which is the most readily accessible for the user.
To guarantee total emp tying of the water content,
both water lines must be laid so as to slope down to
the valves. There shall be no claims under guarantee for
damage caused by frost!
Drill two holes, diameter 11 mm, in the floor of the vehicle and
secure the valves (1 + 2) with 2 screws each.
Connect the connection nozzles (3 + 4) and the valves
(1 + 2) to the water hose, dia. 10 mm (max. length 40 cm).
