5.5 OPERATION WITH INHIBITOR FOR CALCAREOUS DEPOSITS
The KE Classic does not include a device with inhibitor for calcareous deposits in the series equi-
pment. A device with inhibitor for calcareous deposits and ionic acceleration is available only as
optional and must be installed on the suction and does not need any maintenance.
The KE Super and KE Xtra include a device with inhibitor for calcareous deposits in the series
equipment that prevents the formation of calcareous deposits in the circuit after the operation with
hot water. It is sufficient to pour the inhibitor NO-KAL, already duly proportioned, in the tank
(19) and to periodically check the level through the tank plug.
WARNING
• In the absence of inhibitor for calcareous deposits, to prevent damages to the proportioning
pump, fill the tank (19) with water.
