7.6 Decalcification of the cooling water circuit
Personnel:  Operating personnel
1. Switch off the device and prepare the decalcification process
accordingly.
The descaling agent should be fed to the water
cooling using a pump or a funnel through the
supply hose. The descaling agent return flow
should be via flow hose of the water cooling into a
container with sufficient capacity (at least 10
litres).
LAUDA descaling agent (catalogue number LZB
126, 5 kg packaging) is required for decalcifica-
tion. Read the safety instructions and the instruc-
tions for use on the packaging for handling the
chemical.
2. Clean the water filter of the device. The water filter is in the
supply of the water cooling.
Further information for cleaning the water filter can
be found in
Ä
Chapter 7.5 ‘Cleaning the water
filter’ on page 52 .
3. Fill the supply hose of the water cooling with LAUDA desca-
ling agent (pump or funnel). Continuously refill or pump the
descaling agent. Continue this process until the foaming
reaction goes down. This is usually the case after approx. 20
to 30 minutes.
