5.14.1 Instructions and measures on prevention of galvanic corrosion
Installation Instructions
Several measures must be considered when making the installation so that galvanic corrosion can be avoided as
much as possible:
• Separation of the water column (between raw water and generator) after shutdown. This can either be a stop vlave
turned by hand (Attention! The valve must be closed after each operation) or by the installation of an automatic ventilation
valve. In this case the valve opens and closes automatically.
• Connecting all components (hull outlet, generator, heat exchanger etc.) to a common potential. For this all elements
of the installation are connected by a cable (earthed).
• Strict separation of the generator from the 12 V on-board power supply, that means potential free installation of the
12 V system (generator installation und general on-board power supply).
Please find more details in the information sheet „galvanic corrosion (electrolysis)“ which you can order at Fischer
Panda free of charge.
5.15 Checking and filling of the oil circuit
Check oil and fill the oil circuit as described in the service chapter.
5.15.1 First filling and ventilation of the internal cooling water circuit
The expansion tank is supplied with a pressure relief
valve in the cap with 500 m bar. It is possible when operating
the generator hot cooling water can leak here if
there is an overpressure. When working always wear
protective clothing and ensure an adaquate installation
location.
1. Fill up the external cooling water expansion tank with
coolant.
ATTENTION: Maximum fill level = „max.“- marking
The cover of the external expansion tank must be opened
temporarily (all other closures are now closed!).
