Preparations
2.2.2 Filling and venting the engine cooling system
Coolant with anti-freeze
Fill the cooling system with a mixture of potable tap
water and anti-freeze containing a corrosion-
preventive additive for engine cooling systems.
WARNING
Use only anti-freeze agents with corro-
sion-preventive additives for engine
cooling systems that have been ap-
proved in the CHP module manufactur-
er's instructions for operating re-
sources. Please refer to section 2.3
"Coolants" for a list of anti-freeze
agents with corrosion-preventive addi-
tives for engine cooling systems and
further information about the water
quality required.
Handling anti-freeze concentrate
WARNING
When handling anti-freeze concentrate
wear protective gloves and goggles
Please observe the safety data sheet
(which can be obtained from glycol
suppliers).
If having been in contact with the concentrate:
●
Objects
Wipe off any spillage with an absorbent material
and dispose it as special refuse.
●
Skin
Wash the relevant parts of the body with water and
soap.
●

for the CHP module.
Operating instructions for the natural gas-fuelled CHP module VITOBLOC 200
CAUTION
Do not use containers designated for
drinking water or foodstuffs.
WARNING
A minimum concentration of 30 vol.-%
of anti-freeze agent must always be ob-
served, since the corrosion protection
will not be ensured with less than the 30
vol.-% as required.
NOTE
Since the CHP module will be put up in
frost-free rooms (minimum temperature:
+10 °C), a higher anti-freeze concentra-
tion is not required. The cooling system
has been designed in such a way that a
coolant with a maximum of 30 vol.-% of
anti-freeze can remain in the system in
Central Europe also in summer, as long
as the cooling system as such functions
reliably.
