If using the ROTAVAC vario control or Rotavac vario
tectogetherwiththeROTACOOLreuxcooler,place
the ROTAVAC vario control or ROTAVAC vario tec di-
rectly on top of the ROTACOOL.
If using the ROTAVAC vario control or ROTAVAC vario
tecwithouttheROTACOOLreuxcooler,anextrafoot
has to be installed for operation with the condensate
cooler (13; included in the scope of delivery of the con-
densate cooler). Position the ROTAVAC vario control
or the ROTAVAC vario tec simply on the extra foot,
thereby placing the pump’s feet in the four hollows of
theextrafoot.
Install the coolant hoses in such a way that the stability
of the pump is assured even with a full catchpot
