Filling
Take care that no liquid enters the interior of the circulator.
 Recommended maximum filling level with water as bath fluid:
30 mm below the tank rim
 Recommended maximum filling level with bath oils:
40 mm below the tank rim

After filling, immerse the samples in the bath or place the lid
on the bath, in case the opening is not to be used.

The circulator provides an early warning system for low level
that may be triggered when changing samples in the bath.
Draining
 Turn the unit off with the mains switch.
 Place the heating circulator near the rim of the table. Use a
suitable vessel as recipient for the bath fluid.
 Unscrew the drain plug on the front of the bath tank to drain
the bath.

For applications near the ambient temperature, the cooling coil
must be connected to the water mains.
 Using tubing, connect the cooling coil (25a) to the tap water
supply, and lead the tap water in a sink through the return
connector (25b).

A specific water flow rate of 100 ml/minute is sufficient to
compensate for the characteristic temperature.

For applications near ambient temperature (20 °C), the
cooling water temperature should at least be 5 °C below the
working temperature
