6.11.2 Adding coolant
ENVIRONMENTAL NOTE
Risk of environmental pollution due to incorrect handling of service products
Incorrect handling of environmentally hazardous service products can cause serious damage to the en
vironment.
For this reason:
S Follow the safety instructions.
S Take suitable measures immediately if environmentally hazardous fuels, lubricants or coolants escape
into the environment.
S Inform the relevant local authorities of the damage.
The engine's cooling system is to be filled with a mixture of tap water and antifreeze (ethylene glycol or an
ticorrosion agent). Coolant must be filled according to the filling specifications of the BHKW (combined heat
and power plant) manufacturer.
For suitable antifreeze agents see approved Fuels, Lubricants and Coolants according to MAN 324 NF and
MAN 248.
Coolant may only be filled at the filler neck.
S Remove cap.
S Slowly fill coolant.
S Close expansion tank.
S Run engine for approx. 15 minutes at rated speed.
S Shut off engine and carefully unscrew cap with safety valve to the first stop to release pressure, then
carefully open. Add coolant if necessary.
S When adding coolant, do not add cold coolant to a warmed-up engine. Ensure that the proper mixing
ratio of “water/antifreeze" is maintained.
S Check coolant before the next commissioning (with engine cold). Add coolant if necessary.
S Repeat this procedure until coolant can no longer be added.
