Bleed Throat Seal Liquid
Cartridge
To effectively coat the purge rod, air must be bled out of
the TSL cartridge weekly. Perform this procedure after
replacing the mix module or front end to bleed TSL from
cartridge. Before replacing the mix module or front end,
bleed all TSL to prevent spilling TSL.
1. With bleed port facing away from you and with air
supply connected, use a 5/16 in. nut driver (sup-
plied) to slowly open the bleed valve 1/4 to 1/2 turn
until air/fluid begins to slowly exit the valve. See FIG.
15.
2. When no more air comes out of the bleed valve,
close the bleed valve.
