Filling and connection of external circuit

Fill the equipment with heat transfer liquid to suit the operating temperature.

Note: The T 4600 (W), 7000 (W) and 10000 (W) should not be filled with pure water,
but only with Kryo 30 or a water-glycol mixture (minimum 70 % : 30 %)!
When using water as heat transfer liquid at T 1200 (W) and T 2200 (W) please make
sure that there are no operating temperatures below 5 °C in the outflow. Set the
outflow temperature limitation TiL to 4 °C! ( Section 7.6.4.3).
Use Kryo 30 ( Section 6.4) if you are not sure!
To assist in venting the pump, the pressure connection should be left open when the equipment is
filled for the first time, otherwise there may be permanent damage to the pump!
Remove the plug on the filler opening at the front. A funnel can be used for filling.
When starting up for the first time, fill the bath as full as possible, up to the maximum level indication.
After filling up an external circuit further heat transfer liquid may have to be added.
Level indication
Filler opening

For operating temperatures above 50 °C fill up to "Minimum".
In case of larger bath volumes open the overflow. ( Section 6.1).

For operating temperatures below 0 °C fill up to "Maximum" if possible in order to allow for
volume changes.

For optimum operation, the bath level must be between "Minimum" and "Maximum".
Connect the pump connections at the back of the equipment to the external circuit. The external
circuit must be pressure-tight.
 Switch off the equipment before releasing the hose connections; the hose

The pumps installed in the equipment can produce pressures above 1 bar which
can cause breakage of glass apparatus!
Note the maximum permitted pressure of the apparatus in the external circuit!
Pressure limitation through bypass ( Section 7.2).
For suitable hose material, please see ( Section 6.4).
