Decalcifying the cooling water circuit
At regular intervals of 3 months or longer (depending on the water hardness / degree of contamination
of the cooling water) the water-cooled condenser must be decalcified or cleaned.
Required equipment:
−
Two containers of 10 to 20 liters.
−
Use a suitable pump (drum pump) or possibly use hose with a funnel with funnel located
above the cooling water inlet.
Hose between container, pump and cooling water inlet and also between cooling water outlet and con-
tainer.
Standard
Alternative
Via the water inlet hose, fill the device with decalcifier (pump or hose). Set the set value to 10 °C; after
the chiller starts the water circuit can be filled. Circulate the decalcifier with the pump or continue to top
up the decalcifier. Allow the decalcifier to have an effect (see table below). Then drain the device.
Again connect the device to the water supply and thoroughly flush it out (see table below).
Acting time
Continue with the pumping process until the foaming reaction decays. Generally, this is
achieved after about 20 to 30 minutes.
