It also becomes illegal to use
the appliance!
Guarantee claims are to be
sent dircetly to the control
panel (wall switch) manufactu-
rer.
The installer (manufacturer) is
responsible for keeping to
these specifications.

Electrical connection
230 - 240 V
Attention:
The electrical
connection is only to be car-
ried out by an expert (in Ger-
many, acc. to VDE 0100, Sec-
tion 721). The information
given here is not intended as
information for the layman,
rather it is to for assisting the
assigned expert, as additional
information, when connecting
the appliance!
The connection to the power
supply is by means of a cable
3 x 1.5 mm
2
(e.g. flexible
sheathed cable H05VV-F) to a
splitting box (not included in
scope of delivery).
Always pay attention to con-
nect carefully with the correct
colours!
For maintenance and repair
work a disconnecting device
must be provided on the ve-
hicle for all-pole disconnec-
tion from the power supply,
with at least 3 mm contact
clearance.
Connection with
Truma control panel
1. Connect control panel
cable, 230 - 240 V cable and
heating element cable as
shown in the drawing.
1 = Control panel cable
2 = Supply line 3 x 1,5 mm
2
3 = Heating element cable
4 = brown
5 = green
6 = blue
7 = yellow
8 = white
9 = yellow/green
2. Assemble the splitting box
(
Fig. B: 44
) on the vehicle
floor or on the wall, in the
vicinity of the appliance
(observe cable length 90 cm!).

Water pipe routing
1. Figure C:
Connect cold
water supply (30) to safety/
drain valve (13). Direction of
flow is unimportant.
2. Figure D:
Screw elbow
with integrated breather valve
(15) to hot water connection
pipe (upper pipe) and elbow
without breather valve (16) to
cold water connecting pipe
(lower pipe).
Slide on nut (17), tension ring
(18) and O-ring (19). Assem-
ble screw connector and
connecting pipe and fasten
together using nut (17).
Slide ventilation hose with
11 mm outer diameter (20)
onto the breather valve hose
nozzle (21) and route towards
the outside. Do not allow the
radius of the arc to be less
than 40 mm.
Cut off the ventilation hose
approx. 20 mm below the
floor of the vehicle at an
angle of 45° to the direction
of travel.
3. Figure C:
Produce hose
connection (32) for cold water
supply between safety/drain
valve and elbow (lower pipe)
on water heater.
4. Route the hot water pipe
(33) from the elbow with inte-
grated breather valve (15 -
upper pipe) to the hot water
consumers.

Installation of the
control panel (gas
operation)
Choose a place where the
control panel is not exposed
to direct radiant heat.
Length of connecting cable:
2.5 m.
A 5-meter long extension
cable is available, if necessary
(Art. no. 70000-53500).
Pass control panel cable
through the cable binder on
the back of control panel.
Connect cable to the control
panel and tighten cable binder
as strain relief.
Fasten control panel using
2 screws and route the cable
to the water heater.
Note:
Depending on the in-
stallation, the routing of the
control panel cable can be
done in the other way. This
means first connect to the
water heater and then route
to the control panel.
5
Electrical
connection 12 V
Always disconnect the ap-
pliance from the power
supply prior to working on
electrical components. It is
not sufficient to just switch
off at the control panel!
The appliance must be dis-
connected from the vehicle
main power supply when car-
rying out any electric welding
work on the vehicle body.
Attention: If the connec-
tions are transposed there
is a risk of cable burning.
This also rules out any gua-
rantee or liability claims.
Fig E:
Unscrew cover (39)
from the electronic control
unit. Slide cable connector of
control panel (38) onto the
p.c.b.. The electrical connec-
tion is made at terminal (40)
(red = positive, blue = nega-
tive), for this purpose press
with a small screwdriver from
above and push in cable from
the front. Connect to fused
vehicle mains (central electri-
cal equipment 5 - 10 A) using
a 2 x 1.5 mm
2
cable.
Negative cable to central
earth. With lengths of over
6 m use a cable 2 x 2.5 mm
2
.
If connecting directly to the
battery, the positive and nega-
tive cable must be fused.
Screw cover (39) back on.
There are to be no other con-
sumers connected to the sup-
ply line!
The water heater fuse,1.25 A
EN 60127-2-3 (slow-acting) is
on the p.c.b. (41).
When using power packs,
observe that the appliance is
only to be operated with
safety extra-low voltage ac-
cording to EN 60742!
Note:
For the connection of
several 12 V appliances we re-
commend the electronically
controlled Truma power pack
NT (Art. no. 39900-01). The
Truma power pack (6 A conti-
nuous current) is also suitable
for charging lead batteries.
Other charging devices are
only to be used with a car
battery acting as buffer.
Power packs and power supp-
ly units must have a stabilised
12 V-output (ripple content
less than 1 Volt).

Gas connection
Fig. F:
A 1/4“ BSP female
iron gas inlet connection is
provided with the appliance.
Check for gas leaks (do not
check for gas leaks with a
naked flame), then check
that the gas pressure is as
follows:
Propane gas: 2.75 kPa
Before connecting to the wa-
ter heater make sure that the
gas lines are free from dirt,
chips and such!
Route the pipes in such a way
that the appliance can be re-
moved again for servicing.
In areas frequented by peo-
ple, keep the number of par-
ting connections in the gas
supply line to an technically
feasible minimum.
The gas system must comply
with the technical and admini-
strative regulations of the
country in which the appli-
ance is used (in Germany, for
example, the DVGW form
G 607).

Installation of the
control panel
(electrical operation)
Truma control panel
Fig. E:
When selecting the
place of location, always
make sure that the control
panel (43) is not exposed to
direct heat radiation.
Drill a hole with 8 mm dia-
meter for leading through the
cable and pass the cable
through the hole. Fasten con-
trol panel with the two
screws and route the cable to
the appliance.
When using specific
vehicle or manufac-
turer control panels
The switch must be in accor-
dance with our technical spe-
cifications.
The installer (manufacturer) is
responsible for providing
operating instructions for the
user and for clearly identifying
the control panel.
Attention:
Any alteration to
the supplied Truma parts, as
well as the non-observance of
the respective fitting and
operating instructions, shall
invalidate the guarantee and
exclude liability claims.
