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 cooling condenser and fix it in place.
u
Connect the outgoing cable (3) 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.
NOTE
Installing automatic mode sensor on R-220 Pro:
The installation of the automatic mode sensor on the Rotavapor R-220 Pro is de-
scribed in the operating instructions of the Rotavapor R-220 Pro.

Connecting foam sensor (optional accessory)
The foam sensor uses infra-red to measure the level of foam formation inside the
evaporating flask and initiates one or more short venting bursts to combat the foam.
When de-foaming is active, it is indicated by the symbol
on the status bar of the
Interface I-300/I-300 Pro.
The foam sensor passes through the cooling condenser of the R-300 into the evapo-
rating flask. The communication cable from the foam sensor is connected to the Vac-
uBox, see Chapter 3.5.3 "VacuBox (connections)", page 16.
NOTICE
Risk of heat damage to electronic components
u
Only use the foam sensor at vapor temperatures up to 85 °C.
