GAS SUPPLY CONNECTION
Use a 3/8 inch ID inert gas hose to connect the gas supply (air or nitrogen) to the filter at the rear of
the power supply. To connect the hose to the power supply, install a 1/8 NPT nipple or adapter to the
filter block as shown in Fig. 3-12. Apply liquid pipe sealant to the threads to ensure a leak-free instal-
lation. A nipple and adapters are included with the consumable parts kit.
CAUTION: Never use PTFE tape when installing the nipple or adapters. Bits of tape can break
off and enter the air line and harm the pressure regulator, pressure switch and valve.
