Lubrication

See Accessories on page 53 to order lubricant. Liber- ally lubricate all o-rings, seals, and threads.

NOTICE

Use only Throat Seal Liquid on the o-rings, seals, and threads of the Throat Seal Liquid cartridge. Fusion grease or other petroleum-based or vegeta- ble-based lubricants will cause cartridge o-rings and seals to swell and stick.

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.
