3 Safety/drain valve
4 Cowl for combustion air
intake and exhaust gas
discharge
Important
operating notes
1. If the cowl has been
placed near or directly be-
neath an opening window,
the device must be equipped
with an automatic shut-off
device in order to prevent op-
eration with the window
open.
2. Always mount the cowl
cap if the water heater is not
being used. Non-observance
of this point can lead to the
function of the appliance be-
ing impaired through water,
dirt or insects.
There shall be no claim under
guarantee if this point is not
observed. Always remove the
cowl cap prior to operating
the water heater!
3. If just the cold water sys-
tem is being used, without
water heater, the heater tank
is also filled up with water. In
order to avoid damage
through frost, the water con-
tents must be drained by ac-
tuating the safety/drain valve,
also when the heater has not
been used. As an alternative,
two shutoff valves, resistant
to hot water, can be fitted in
www.westfaliaLT.info - a useful site for enthusiasts and owners of VW Westfalia LT campers
front of the cold and hot wa-
ter connection.
4. When connecting to a cen-
tral water supply (rural or city
mains), a pressure reduction
valve must always be in-
stalled to prevent pressures
above 2.8 bar from develop-
ing in the water heater.
Before using for the first
time, it is essential to
flush the entire water supply
through with clean warm wa-
ter. Always mount the cowl
cap when the water heater is
not being operated! Drain the
water heater if there is a risk
of frost! There shall be no
claims under guarantee for
damaged caused by frost!
In the event of malfunctions
please always contact the
Truma Service division
(see page 24).
The installer or vehicle owner
must apply the yellow sticker
with the warning information,
which is enclosed with the ap-
pliance, to a place in the ve-
hicle where it is clearly visible
to all users (e.g. on the ward-
robe door)! Ask Truma to send
you stickers, if necessary.
Boiler BS 10, BS 14
Liquid gas storage water heater
Maintenance
The water container
used is made of VA
stainless steel, which is food-
stuff-compatible.
Use wine vinegar for de-scal-
ing the water heater, this be-
ing introduced into the appli-
ance via the water supply. Al-
low the product to react and
then thoroughly flush out the
appliance with plenty of fresh
water. To sterilise the water
we recommend „Certisil-Ar-
gento". Other products, par-
ticularly those containing
chlorine are unsuitable.
To avoid infestation by micro-
organisms, the boiler must be
heated to 70°C at regular in-
tervals.
Do not use the water as
drinking water!
Fuses
The fuse for the device is
located on the electronic
control unit.
The fine-wire fuse must only
be replaced by a fuse of the
same design:
1.6 A (slow-acting),
EN 60127-2-3.
If there is a defect in the elec-
tronics return the control
p.c.b. well padded. If you fail
to pack it correctly the guar-
antee shall no longer be valid.
Only use original Truma water
heater control p.c.b.'s as
spare parts!
