Attention! Once descaling is ended, do not leave the descaling liquid in the tank.
• To eliminate the acid solution, lose hold inlet and outlet nuts and wait to the liquid leaves. Beware with
the residual acidity, in order not to damage the pavement or other surfaces.
• Once the antiscale treatment is finished, a neutralizing washing for the residual acidity is required with
the Rothenberger Neutralizing powder.
• Connect the sanitary water inlet and lose hold the outlet. Flush the water heater with fresh water.
• Finally connect the sanitary water outlet and flush with clean water once more
Important! Colour change from red into yellow-orange will indicate that the descaling capability
is exhausted.
If the pump is not used for a period of time, wash out the pump after use by circulating clean water
through it.
