necessary connections and hardware.

PREPARATION OF LEADING EDGES.
If the leading edges are painted, remove all paint including zinc chromate primer.
1. With one inch ( 1 ) masking tape, mask off leading edge boot area, allowing 1/2 inch margin for non-
recessed boots. Take care to mask accurately, thus eliminating the need for cleaning off excess cement later.
2. Clean the metal surfaces thoroughly, at least twice, with MEK or Acetone. For final cleaning, wipe the
solvent film off quickly with a clean, dry cloth before it has time to dry.
It is permissible to install deicers on alodined or anodized surfaces
3. Fill gaps of skin splices that lead under deicers with sealing compound EC-801.
4. Remove the sump plugs from the air connection grommets. In some cases, it will be necessary to remove
sections of doped fabric used to cover the air connection holes. Draw out the ends of the non-kink hose
section so that they protrude through the connection holes in the leading edge. If hose is cracked or
deteriorated, replace with new hose.
