1. Coolant feed line max. 70 °C in permanent operation mode at maximum load
2. Coolant return line max. 85 °C in permanent operation
mode.
3. Differential of the two values: This item is of particular importance and provides information on the circulation of
the coolant. The difference should be max. 17 K for a coolant water system with an integrated water-cooled muff-
ler. It should, however, typically be between 10 and 12 °K.
If the difference is greater than 15°K, the coolant circulation is not sufficient. The water circulation must then be
increased. This can be solved by e.g. improving the line routing, or by reducing the belt pulley diameter. It is absolu-
tely necessary to measure the output of the cooling system after installing the generator. The values given above
shall be considered maximum permissible values. They apply to operation in increased temperatures, as well. In
permanent operation mode at external temperatures around 20 °C, the values must fall near the lower limit of the
tolerance.
Note:
Each manual includes installation certificates, which
must be filled in after installation and returned to the
manufacturer (copy).
Returning the installation certificates and
commissioning logs is an important component of the
warranty conditions.
5.10 Custom installations
The effects on the warranty must be agreed on a case-by-case basis with Fischer Panda.
5.10.1 External heat exchangers
External heat exchangers shall be installed as per the specifications of the respective manufacturers.
5.10.2 External engine pre-heater
