6-3. Tube Fitting Connection Procedure
Install the provided half union tube fitting into the filter unit inlet and gas outlet.
When metal tube fittings (not provided) need to be installed into the filter unit inlet and gas outlet.
Over tightening the filter unit inlet may break the gas inlet. When connecting the
provided half union to the filter unit inlet, secure the filter unit inlet with one adjustable
wrench or spanner, etc. to prevent filter unit inlet from rotating and another to install the
half union.
Over tightening metal tube fittings may break the gas outlet. To prevent this, install the
provided gas outlet spacer to the gas outlet first, then connect the metal tube fitting
over the spacer.
Use metal tube fittings (Swagelock SS-6MO-1-4RT or equivalent) for both gas inlet and
outlet.
Wrap sealing tape tautly around the threads of each metal tube fitting to prevent slack
(approx.2.5 wraps).
Tape size: 13mm (width) x 100
5mm (length) x 0.1mm(thickness)
Tighten the metal tube fitting until hand-tight. Do not over tighten the tube fitting or the
gas outlet may break.
