u
Connect two tubes between the AutoDest sensor (2) and the cooling condenser
(4). When doing so pay attention to the direction of flow of the coolant. The arrows
on the AutoDest sensor indicate the direction of flow.
NOTE
The distance between the AutoDest sensor and the cooling condenser should not be
more than 10 cm so as not to falsify the readings for the incoming and outgoing
coolant temperatures in the distillation system.
u
Connect a tube between the coolant inlet (5) on the AutoDest sensor and the out-
let of the recirculating chiller.
u
Connect a tube between the coolant outlet (6) on the AutoDest sensor and either
the inlet of the recirculating chiller or another cooling condenser.
u
Insert a vapor temperature sensor (1) in the Rotavapor R-300 and fix it in place.
u
Connect the outgoing cable from the AutoDest sensor to the VacuBox. Use the
connection marked "VT/AS" for this lead.
NOTE
There should be no air bubbles in the coolant as otherwise correct functioning of the
AutoDest sensor is not guaranteed.

Fitting a foam sensor (optional accessory)
The foam sensor measures foam formation in the evaporating flask and emits a
signal if the foam reaches the foam sensor. The foam is reduced by a short ventilation
burst.
