Fresh Water (Coolant) Level Indicator and
Alarm (Figure 10) - When the amount of
cooling water in the fresh water recovery
tank falls below normal, the sensor will send
a signal to the indicator causing it to light and
the alarm to sound. Stop operation
immediately to avoid damage to the engine.
Check the water level in the cooling water
recovery tank and troubleshoot the cooling
system.
