WARNING
Methanol and ethanol can give o󰀨 am‑
mable and explosive gases. Therefore, the
safety provisions for the anti‑freeze must
be noted and followed!
The hazard markings of all anti‑freezes
used must be noted and the relevant safety
provisions must be followed.
► Make sure that the mixing ratio of water and antif-
reeze agent meets the required minimum antifree-
ze temperature in the heat source.
 “Technical data / scope of delivery“, from
page 22, “Heat sorce” section
► For operation of the heat source with water or
water-antifreeze mixture, ensure that the water
used fulls the quality specications of the heating
water side.
 “Heating water quality“, page 19

1. Flush the heat source system thoroughly.
2. Mix antifreeze with water thoroughly with the
required ratio, before adding to the heat source.
3. Check the concentration of the water-antifreeze
mixture.
4. Fill the heat source with the water-antifreeze
mixture.
Fill until the system is air-free.
19.2 Flush and ll the heating circuit
Unsuitable quality of the water for lling up
and replenishing the heating circuit
The e󰀩ciency of the system and the service life of the
heat generator and the heating components depend
decisively on the quality of the heating water.
If the system is lled with untreated drinking water, cal-
cium deposits will form as scale. Lime scale deposits
accumulate on the heat transfer surfaces of the heat-
ing. The e󰀩ciency is reduced and energy costs in-
crease. In extreme cases, the heat exchangers will be
damaged.
Heating water quality
NOTE
● For detailed information refer, among
other things, to the VDI Guidelines
2035 “Vermeidung von Schäden in
Warmwasserheizanlagen”
● Required pH value: 8.2 … 10;
for aluminium materials:
pH value: 8.2 … 8.5
► Fill the system with deionised heating water
(VE water) or with water corresponding to VDI
2035 only (low-salt operation of the system).
Advantages of low-salt operation:
● Low corrosion-promoting properties
● No formation of mineral scale
● Ideal for closed heating circuits
● Ideal pH value due to self-alkalisation after lling
the system
► If the required water quality is not achieved, con-
sult a company specialising in the treatment of he-
ating water.
► Keep a system log for hot water heating systems
in which relevant planning data is entered (VDI
2035).
