Filling And Draining - IKA HRC 2 basic Operating Instructions Manual

Note: Please note the permissible temperature range of
hoses� For hot fluids we recommend the IKA
hoses�
When the external system is not necessary, please seal
the pump connector IN and OUT with the existing union
nuts and stoppers�
When IKA calorimeter is not connected, please close
®
the "Backflow" connector with included backflow cap�
In case of closed external system, if there is in any case no
risk of exceeding the maximum fluid level, you can close
the "Overflow" connector with the included overflow
cap� This minimizes the energy loss and protects, in case
of long-term applications with low temperatures and
high humidity, against unwanted water input and the as-
sociated volume increase�
Check fluid heat expansion!

• Filling and draining:

- Before filling the fluid into the bath, open the venting
grid as indicated in following figure�

tate clockwise to the stop position, see Fig� 8)�

Meanwhile, the bottom LED segment of fluid level indi-
cator lights up in red color to indicate the low fluid level
(see Fig� 9)�
- Open the filling opening lid (4) and remove the stopper
from the filling opening� Then, fill fluid to the bath�
Note: The stopper must be kept being plugged in dur-
ing during operation except for filling fluids�
