B. Main Pump Assembly
The main pump assembly consists of two electrical pumps which are connected in series. These
pumps are mounted to the bottom side of a lid in the floor of the nose baggage compartment on the
RH side.
The main pump assembly has two outlets. One outlet supplies the airframe ice protection system
(see Paragraph C). The other outlet supplies the windshield de-icing system (see Paragraph D).
C. Airframe Ice Protection System
(1) High Pressure Sensor
A high pressure sensor is situated between the main pump assembly and the filter. It is attached
to the LH inspection hole cover in the nose baggage compartment.
When the resistance of the filters becomes too high, the sensor activates a caution message
("DEIC PRES HI") on the Garmin G1000 PFD. The system remains operative, but the filter
cartridges must be replaced at the next scheduled inspection.
(2) De-Icing Fluid Filters
Two filters protect the capillaries in the proportioning units from fouling . The filters are connected
in parallel for redundancy purposes. The outlets of the filters are merged with a T-fitting and then
the fluid runs underneath the cockpit floor to a manifold block in the center of the airplane. Each
filter has a bleeding socket connected to a bleeding hose, which is located in the LH nose
baggage compartment.
(3) Manifold Block
The manifold block is located under the small center console between the center wing main
spars. It divides the flow of de-icing fluid into three branches. One branch goes to each wing to
feed the wing and propeller ice protection system (see Paragraph 4). One branch goes back to
feed the empennage ice protection system (see Paragraph 5).
