Installation of the control panel
When using control panels which are specific to the
vehicle or the manufacturer, the electrical connection
must be established in accordance with the Truma interface
descriptions (refer to Electrical connection 230 V ~ / 240 V ~).
Any modification made to the Truma components pertaining
to this will void the warranty and exclude any liability claims.
The installer (manufacturer) is responsible for providing usage
instructions for the user as well as for identification printing
on the control panels.
When selecting the location, bear in mind that the control
panels must not be subjected to direct radiant heat. Length
of connection cable 3 m. If required, a cable extension of 5 m
can be supplied (refer to page 12).

Drill a hole with diameter 55 mm.
Plug the control panel cable (28) to the control panel for gas
operation (26) and then fit on the rear cover cap (29) as a
stress-relieving device.
Push the cable through to the rear and lay the connection
cable (28) to the Truma UltraRapid HWS.
Lay the connection cable with the orange multipole connec-
tor (28) to the 12 V control electronics unit (for connection
refer to Electrical connection 12 V).
Secure control panel with 4 screws (31) and fit the cover
frame (32) on it.
If a flush installation of the control panel is not possible,
use the surface-mounting frame (25) as supplied.
Electrical connection 12 V
Disconnect device from power supply before starting to work
on electrical components. Switching off at the control panel is
insufficient!
The device must be disconnected from the on-board power
supply when electric welding work is being carried out on the
vehicle body.
Reversing the polarity of the connections will result in
a risk of cable fire. Any warranty or liability claims will
also be invalidated.
Push the control panel cable connector (28a) onto the control
board.
In order to attach the cable (28) securely, route it through the
cable guide (28b).
The 12 V electrical connection is made at the clamp (35).
orange = positive 12 V
blue =
negative
This is done by pressing from above with a small screwdriver
and pushing the cable in from the front.
Gas connection
Refer to AS5601 – Gas Installations, for gas pipe sizing.
The gas inlet connection is a SAE 45° Flare 1/2 - 20UNF type.
For connection to 8 mm steel piping Truma povides an adapt-
er UNF 1/2 in. x RVS 8, part no. 70020-02700.

Before connecting to the water 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
removed again for servicing.
Before starting up for the first time, verify the correct installa-
tion in accordance to the requirements of AS5601 (check for
gas leaks and check the gas pressure). Do not check for gas
leaks with a naked flame.
