CAUTION: Do not clean the liner while it is assembled

in the conduit. The solvent will attack and

destroy the conduit’s rubber covering.

C. CONDUIT LINER (For remote mounting installa-

tions only.)

The plastic lined conduit liners (42V73, 42V74, and

42V75) used to feed aluminum should be cleaned

periodically to remove any accumulation of dust or dirt.

A solvent, such as oxylene (trichlorotrifluoroethane,

CCL

) should be forced through the conduit and

then blown out with air. Flushing the solvent through

the conduit 5 or 6 times will be sufficient. The solvent

can be purchased from the J.B. Moore Corp., Nutley,

New Jersey.
