With water with a high calcium content, high heating
output and frequent use, there will be increased cal-
cification of the heater and the bottom of the boiler
even if you use RM 110.
Calcification on the heater and split off calcification residue
on the bottom of the boiler in a test device with a heating
output of 36 kW, approx. 600 operating hours and approx.
28°dH water hardness.
The boiler must be cleaned and decalcified every 400
operating hours:
Decalcify the boiler using decalcifier (e.g. RM
101).
Let lime and acid residue drain via the drain screw.
Rinse the boiler thoroughly with clear water.
Neutralise the boiler using alkaline detergent (RM
31, RM 81) or a soda solution (1 kg Soda 6.287-
014).
Note:
Due to the standing water, a calcification can only be
completely prevented by adding softened, lime-free
water.
