• The coolant pump is designed so that a max. distance of 5 m between pump and radiator is possible.
Note:
If the necessary coolant volume flow is not achieved (e.g.
due to a special installation situation), an external coolant
pump with the corresponding output must be installed in
the coolant circuit to increase the coolant volume flow.
Warning:
The pressure in the coolant circuit must not exceed
0.7°bar!
Required coolant volume flow:

5.9.10 Radiator fan
Radiator fans are wearing parts. To ensure a long service life, there must be no objects impairing or blocking the free
movement of the fan during operation. Such objects include:
• Snow
• Ice
• Leaves
• Branches
• Increased air resistance due to dirty radiator
5.9.11 Anti-freeze and corrosion protection
At the factory, the coolant is adjusted to a 50% concentration of G48 anti-freeze solution (approx. -40°C). If lower
temperatures are possible during transport or storage, the coolant filling must be drained or adjusted for the lower
temperatures.
After draining the coolant, the system must be blown dry with compressed air at 0.5 bar. This will ensure that the
system is complete drained.
The anti-freeze agent also serves to protect the system against corrosion. The anti-freeze concentration in the
coolant must not drop below 30%.
5.9.12 Logging the temperature values during initial start-up
It is mandatory to measure the temperature values of the circulating coolant in the circuit after installing the genera-
tor for the initial start up. Two remote thermometers must be used for this purpose. One connection must be moun-
ted to the coolant feed line to the engine, the second one on the coolant outfeed. The generator must then be loaded
with min. 75% of the rated power after a brief warm-up phase. The circulation of the coolant must be checked. The
values must fall within the following limits:
