6. Continuously top up or recirculate the descaler. Continue this process
until the foaming reaction had subsided. This usually takes 20 to
30 minutes.
7. Then drain the condenser using compressed air.
8. Rinse the device thoroughly with fresh water.
9. You can now connect the device back to the cooling water supply.
1. Switch off the device at the mains switch.
2. Detach the cooling water hose from the cooling water supply intake.
Leave the hose on the cooling water outlet (OUT) attached securely
to the device.
3. Allow compressed air to flow through the cooling water hose towards
the device. Wait until all the water has flowed out of the device before
detaching the compressed air supply.
Contaminated or degenerated heat transfer liquid must be replaced. Con-
tinued use of the heat transfer liquid is only permitted following successful
testing. The heat transfer liquid must be tested as outlined in DIN 51529.
CAUTION!
Contact with hot/cold heat transfer liquid
Scalding, cold burns
Bring the heat transfer liquid to room temperature for anal-

ysis.
The device must be switched off if the bath temperature exceeds the max-
imum temperature [Tmax]. The electronics system switches off the device
components.
PRO bath thermostats and circulation thermostats
Refer to Ä "Draining the water-cooled condenser"
on page 117 for detailed information on draining the con-
denser.
Make sure a minimum of 10 liters of water flows through the
system.
