1. Heat the filter cartridge until material is liquid.

counterclockwise out of the filter screw, then replace.

Installing Filter Cartridge

1. Heat applicator until material is liquid.
2. Apply high temperature grease to the O‐ring. Refer to page 33,
Processing Materials.
3. Slide the filter cartridge into the filter bore.
NOTE: Air penetrates the filter bore when the filter cartridge is replaced. The
applicator is deaerated with the aid of the pressure relief screw.
4. Unscrew the pressure relief screw somewhat.
5. Allow the pump to run briefly until material flows out. This also forces out
the air.
6. Turn in the pressure relief screw clockwise all the way when the material
flows out free of bubbles.
