5.2 Start-up

control unit with the plant set values shown
on the inside of the control unit.
NOTE
Where there is booster heating (e.g. during
manoeuvering when marine diesel or lighter
fuel is used) the temperature set point must be
reduced to a temperature suitable for the fuel
used.

The temperature increases up to the set

display.
NOTE
Where there is booster heating, the temperature
setpoint must gradually be raised to normal
operating temperature at the same time as the
change-over from light to heavy fuel.
