Servicing (continued)
De-icing Fluid Strainer
The de-icing fluid strainer in the fluid tank outlet should not require cleaning
unless there is a definite indication of foreign matter in the tank.
If foreign matter is found in the tank, flush the tank with clean water until all
evidence of the material is removed.
System Fluid Filter
Replace the system fluid filter every 3 years or 1500 hours of aircraft use,
whichever is less, or anytime if required by condition.
Pump Priming
The metering pump is not self-priming and may require priming in the event the I
TKS tank is run dry or emptied completely. Once prime is established, the pump
will maintain the prime unless air re-enters the pump.
If priming is required, locate the system drain valve on the lower, right inboard
wing, near the landing gear. The valve is forward of the main spar. Fill the TKS
tank completely. The valve is operated by pressing a screwdriver or center-pin
cup into the valve, similar to fuel strainers. The pin may be held in momentarily
to drain for priming.
For complete pump priming, one quart of fluid must be drained. The fluid may
be returned to the tank if kept clean. Assure that the drain valve is closed and not
leaking fluid after use.
