HEATING SYSTEMS
• In mixed mode 230 V electrical mode
is preferred if the power requirement
is low (e.g. for maintaining the room
temperature). The gas burner is not
enabled until the power requirement is
higher, and is the first to switch off during
heat-up operations.
HOT WATER MODE (WITH FILLED BOILER ONLY)
Gas mode or 230 V electrical mode is used to
generate hot water. The water temperature can
be set to 40 °C or 60 °C.
• In gas mode the water is heated at the
lowest burner setting. Once the water
temperature has been reached, the
burner switches off.
• In electrical mode output of 900 W (3.9
A) or 1800 W (7.8 A) can be manually
selected in accordance with the fuse
protection at the camp site. Mixed mode
is not possible. With this setting the unit
automatically selects electrical mode. The
gas burner is not enabled.
OPERATING INSTRUCTIONS
Read the safety instructions and operating
instructions carefully before starting the unit.
The installer or vehicle owner must apply the
yellow sticker with warning information, which
is enclosed with the appliance, to a place in the
vehicle where it is clearly visible to all users
(e.g. on the wardrobe door) Ask Truma to send
you stickers if necessary.
Before using for the first time it is essential to
flush the entire water supply system through
with clean water.
If the heater is not being used, always drain the
water contents if there is a risk of frost. There
shall be no claims under guarantee for damage
caused by frost.
Materials in the device which come into
contact with water are suitable for use with
drinking water (see manufacturer declaration:
www.truma.com – Manufacturer Declaration).
ROOM THERMOSTAT
To measure the room temperature, an external
room temperature sensor (s) is located within
the vehicle by the control panel.
The thermostat setting on the control panel (1–
5) must be determined individually depending
on the heating requirement and the type of
vehicle. For an average room temperature of
about 23 degrees we recommend a thermostat
setting of about 4.
FILLING THE WATER HEATER
• Check the safety/drain valve within the
cold water intake is closed. The lever
should be in horizontal position e.
e. Lever position “closed”
f. Lever position “drain”
• Open the hot tap in the bathroom or
kitchen, with pre-selecting mixing taps or
single-lever fittings set to “hot”.
• Switch on power for water pump (main
switch or pump switch).
• Leave tap open to let air escape while the
water heater is filling. The heater is filled
when water flows out of the tap.
Residue of frozen water can prevent filling
if there is a frost. The water heater can be
defrosted by switching on the heater for a
short period. Frozen pipes can be defrosted by
heating the room.
