Section III - SYSTEMS DESCRIPTION
FLUID STORAGE
De-icing fluid for the system is stored in a tank with an approximate capacity of 10.04 gallons (38 liters).
For a tank indicating full, priming and protection for at least 85 minutes is provided. The fluid contents
indicator on the right side console reads FULL above 8.19 gallons (31 liters), and reads EMPTY when
there are approximately 12 minutes protection still available.
A tank filler cap is accessible from inside the airplane forward of the main entry door. After filling a
completely empty system, the vent valve, located below the tank filler, should be pushed for 10 seconds
to bleed the pump.
NOTE: The vent valve must not be operated while the pump is running.
Warning Annunciators
With the pump running, system low pressure is indicated by the illumination of an amber ANTICE LO
PRESS annunciator on the overhead roof panel and the MWS ICE PROT flashing repeater annunciator.
Fluid low quantity is indicated by the illumination of an amber ANTICE LO QTY annunciator on the
