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 around 5 seconds. Now re-connect the tube to the push-fit connector.
►
First, start a program without any product 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 been warmed up.
