Operation of appliances
?
!Shutting down:
Shut the heater down with the
rotary switch (position f). The green
LED (b) goes out.
SIf the green LED (b) blinks
after the power is switched off,
this means that a shutdown timeout
to lower the unit temperature is
running. This stops after a few
minutes and the green LED (b) goes
out.
Always drain the heater if there is a
risk of frost!
Maintenance :
It is mandatory to use original Truma
parts for all maintenance or repair
work.
The water reservoir is made of steel
used for alimentary applications.
To protect the apparatus from
colonisation by micro-organisms,
use chemical methods to remove
biofilms, deposits and scale. To
avoid damage to the apparatus,
use only non-chlorinecontaining
products.
If necessary, regularly reheat
the water in the water heater to
70° C to maintain the effectiveness
of the chemical method for
combating micro-organisms inside
the apparatus.
Adjust the rotating switch on the
thermostat control to position “c”
(summer mode, 60° C). The green
(b) and the yellow (g) LEDs will light
up.
When the water in the water
heater reaches a temperature
of 60° C, the burner will stop and
the yellow LED (g) will turn off. The
apparatus should remain lighted for
at least 30 minutes and no hot water
should be used. Residual heat from
the thermal exchanger will heat the
water to a temperature of 70° C.
Fuses :
The fuses are in the electronic
control unit underneath the
connector cover. Replace defective
uses with exactly the same fuses
only.
Unit fuse:
10 A - delayed action - (T 10 A)
Burner fuse:
20 A - delayed action - 6.3 x 32 mm
