over the collecting device.
2. Close the return line and open it again by repeatedly and abruptly relea-
sing it, until the coolant is flowing continuously and without air bubbles into
the collecting device.
3. Switch off the circulating coolant unit and connect the coolant return line
again.
Check the level of coolant in the circulating coolant unit.

Set the quantity of gas required on the pressure gauge. Type and quantity of
