4.4 Malfunctions not displayed on control element
1. After switching on, the system does not react. Check the power supply, the
supply line circuit breakers, etc.
2. The compressor starts up, however no sea water exits from the sea water
outlet. If the sea water pump is running:
• Check whether the shut-off valves are opened.
• Check whether the sea water strainer is clogged.
• There could be air in the pump head causing the pump to malfunction.
Bleed the air out of the sea water line, e.g. with a bleeder valve downstream
of the pump.
If the sea water pump is not running:
• Check the power supply to the sea water pump.
• The pump rotor may be blocked by dirt. If possible and accessible, using a
tool turn the pump rotor from the motor side until it moves freely.
