The installer or vehicle owner must affix the
yellow sticker with the warning information,
which is enclosed with the appliance, in a lo-
cation in the vehicle where it is clearly visible
to all users (e.g. the wardrobe door)! Missing
stickers can be requested from Truma.
Always observe the operating instructions
and the “Important operating notes” prior
to starting!
The vehicle owner is responsible
for correct operation of the appliance.
Before initial use, be sure to flush the en-
tire water supply thoroughly with water.
The boiler should be drained when it is not be-
ing used in order to avoid the risk of frost!
No
claims may be made under the warranty
for damage caused by frost!
The materials of the device that come in-
to contact with water are drinking water
safe (see manufacturer’s declaration
www.truma.com – Downloads – Manufaturer’s
declaration).
Filling the boiler
Check that the safety/drain valve in the cold water supply is
closed: Lever horizontal, position (a).
The safety/drain valve must be actuated regularly in
order to prevent limescale deposits and to ensure that it
is not blocked.
Figure 1
a = Lever position “Closed”
b = Lever position “Drain”
Turn on the hot water tap in the bathroom or the kitchen.
In the case of thermostatic or single-lever mixer taps, set to
“warm”.
Switch on power to pump assembly (main switch or pump
switch).
Leave the fittings open for as long as it takes for the boiler to
displace the air and fill up and for water to flow.
In the event of frost, filling may be prevented by frozen resid-
ual water. The boiler can be thawed by turning it on briefly (no
more than 2 minutes). Frozen lines can be thawed by heating
the interior.
Draining the boiler
If the caravan is not being used during the frost period,
the boiler must be drained!
Disconnect power to pump assembly (main switch or pump
switch).
Turn on the hot water taps in the bathroom and kitchen.
Open safety/drain valve: Lever vertical, position (b).
The boiler will now be drained directly to the outside via the
safety/drain valve. Check that all the water has drained out of
the boiler (14 litres).
