Cleaning and care
► Place a suitable funnel in the filler
opening and fill the device with the
necessary quantity of de-mineralised
or distilled water:
approx. 9 litres when
filling from new
approx. 1 litre when
topping up after a warn-
ing or error message
prompting you to top up
Figure 38: Filling
► Stop filling immediately you hear the acoustic signal and see the message "Tank is
FULL".
► Press the confirm button ("OK").
► Screw the plug back into the filler opening. Use a coin to tighten it up.
The device is now correctly filled with heat transfer fluid.
Proceed as following to bleed the heating cushions:
► Pull the left-hand top tube out of the push-fit connector so that the water can rise in
the water ducts.
► Wait for about 5 seconds. Now re-connect the tube to the push-fit connector.
► First, start a program without any material to heat.
► If the pump does not immediately pump heat transfer fluid into the cushions, stop the
program and start it again after waiting for a short time. If necessary, repeat the start
and stop operations a few times until the pump starts pumping fluid.
► Once the heating cushions have been filled, open the cover of the heating chamber.
► Squeeze out any air bubbles present in the cushions with your hands, pressing to-
wards the right-hand tube connection. Any bubbles removed can be heard as a gur-
gling sound.
► Close the cover so that the heating cushions fill up again.
► If there are still significant amounts of air in the heating cushions, the process must be
repeated.
► Small bubbles disappear once the heat transfer liquid has warmed up.
