A. Connecting Gas Supply to Unit
The connection is the same for compressed air or high pressure gas cylinders. Refer to subsection 3.4-C
if an optional air line filter is to be installed.

NOTE
For a secure seal, apply thread sealant to the fitting threads, according to manufacturer's instructions. Do Not
use Teflon tape as a thread sealer, as small particles of the tape may break off and block the small gas passages in
