4 Special accessories
• Nº767 Pipe set: for use of the continuous-flow heater as an under
sink appliance.
5 Decalcification by qualified personnel
• Under normal conditions, the appliance does not require
decalcification. However, the appliance can be decalked if subjected
to extremely hard water and frequent drawing of very hot water.
• To decalcify, use “Calcolith“ (<20% hydrochloric acid) and the
decalcification pump “HACA PX 15 N“. Both are available via the
following company:
Dr. O. Hartmann, D-71665 Vaihingen (Germany).
Note:
Carefully follow manufacturer instructions when using Calcolith and
disposing of the decalcification solution.
• Allow the decalcification solution (mixing ratio: 80% water to 20%
Calcolith) to circulate through the appliance for approx. 20 to 30
minutes.
After decalcification, thoroughly rinse out the appliance with copious
flowing water.
