D. Atta ch maintenance warning tags t o the bat tery and external power recepta cle that have "DO NO T
CONNECT ELEC TRICAL POW ER - MAINTENANCE IN PROGRESS" writtenonthem.
E. Obey the general caut ions, warnings, and instruc tions that follow when you install or work near
the ice prote ction system :
CAUTION: Be c aref ul when you install the porous panels to make sure t hat you do no
damage t o the wing leading edge skin.
WARNING: Fo r health and environmental data, revi ew the Material Safety Data
Sheet (MSDS) for TKS fluid. Refer to the MSDS that should be included
with the sh i pment of T KS fluid. If you cannot locate t he MSDS, contact
your supplier of the TKS fluid to obtain the MSDS.
WARNING: Make sure that yo u use applicable eye protecti on when you wo rk near
the ice protec tio n system. The system uses high pressure in the lines
to operate correctly, and the fluid pressure stays in the system lines
until it is released. If you d o no t use appli cable eye pro t ection, fluid
under pressure can h it y our eyes and cause damage when you do
work on the system.
WARNING: Di scard all unwanted TKS fluid and/o r dirty cloths correctly. TKS
fluid is a hazardous waste and must be disca rded in accord ance with
proced ures a pproved by the local j uri sdiction.
(1) Make sure that you wea r applicable eye protec t ion when you do work on or near the ice
protection system.
WARNING: Before you disconnect components of the TKS anti-ice system, slowly
loosen the coupling th at is connected to the component to be remo ved
because it is possible that hi gh pre ssure is still in the system.
(2) Slowly loosen t he connection at t he necessary fitting to release high pressure in the s y stem .
WARNING: Make sure that you remove ice protection fluid fro m the flo or surfaces
where passengers and personnel walk. Th e flui d can make surfaces
slick.
(3) Remove all ice protection fl uid from areas where people wal k. S ince there i s leakage of fluid
from the panels f or a while after the system is no longer in operation, mak e su re that you
collect fluid that drips f rom the airplane or continue to remove fluid from the floor until there
is no more leakage.
CAUTION: Never us e unapproved ice protection fluids in the ice prot ec ti on system. Never
use a thicke ned ant i-ice fl uid or one that i s made for use on the r unway, in
automobiles, or on pa rked airplanes. If you us e fluids that do not meet the
DTD406B specificat ion, you will do damage to the membranes in th e porous
panels and other system compon ents.
CAUTION: Use only clean, filtered fluid in the TKS system. C ontamination will cause fluid
blockage and/or damage to t he porous panel.
(4) Use only i ce protection fluids that m eet t he DT D 406B s pec ific ation in the ice protec tion system .
(5) You can mix flu ids that meet the DTD406B s pec ific ation in any proportions in the airplane tank.
