4.3.2 Connecting the water pads
•
The hose bracket (7) provided makes it easier to lay the hoses
between the pad and the unit. To attach the bracket, loosen
the two knurled screws (8) on the left-hand side of the unit and
then use them to fasten the bracket.
•
Push the hose device couplings of a hose extension onto the
coupling pair (9) on the unit.
•
Push the hose pad couplings of the hose extension onto the
coupling pair on the water pad.
•
The couplings are then correctly connected to each other when
the locking mechanisms on the couplings are engaged in their
corresponding counterparts in such a way that the connection
will no longer come loose by itself.
•
You can loosen the coupling again by pushing the metal plate
on the hose coupling and pulling the coupling out.
► The coupling connections of the hose extension cannot be
"confused" when connecting them to the couplings of the unit
since it makes no difference in what direction the water flows
through the water pad.
► Water pads can also be decoupled when the unit is switched
on. Water dripping out of the coupling is in this case quite
normal and does not indicate a leakage or defect.
In heating operation at 39 °C: Reduce the nominal
temperature before decoupling the water pad.
In cooling operation at 15 °C: Increase the nominal
temperature before decoupling the water pad.
The water in the unit circuit may otherwise briefly go above
the upper or lower limit temperature and the unit may trigger
various alarms.
