6.7 PARTS REPLACEMENT AND ADJUSTMENT PROCEDURES

Using a strap wrench, remove the old element and gasket.

Clean the gasket seating surface.

Apply a light film of fluid to the new gasket.

Hand tighten the new element until the new gasket is seated in the gasket groove.

Continue tightening element by hand an additional 1/2 to 3/4 turn.

Restart the machine and check for leaks.

Always perform maintenance on both fluid return/sight glasses at the same time.

Disconnect the tubes at the tops of the sight glass assemblies.

Unscrew male connector (for left-side glass), or the straight thread tube connector (for right-side glass) from sight glass/orifice blocks.

Remove used filter assembly, and replace with new assembly.

Coat/lubricate the O-rings will silicone grease.

Reattach the connectors to the sight glass/orifice.

Refer to Figure 6-4. Prior to adjusting the Control System, it is necessary to determine the desired operating vacuum range.

The following explanation applies to a typical installation with a desired operating vacuum of 20 in-Hg. (508mm). This information will apply to a vacuum unit with any other operating vacuum except for the stated vacuum.

The vacuum regulator should be adjusted for the vacuum at which modulation of gas delivery should begin. In this case, the vacuum will be 20 in-Hg. (508mm).

The regulator is adjusted by loosening the jam nut on the end of the cone shaped spring cover of the vacuum regulator.

When the jam nut is loose, turn the adjusting screw clockwise to increase or counterclockwise to decrease the setting.

Above 20 in-Hg. (508mm), the regulator will allow atmospheric pressure to flow into the control chamber of the Sullicon Control.

At this time, the Sullicon Control lever should start to move.

If the vacuum unit is equipped with the optional dual control, the vacuum switch contacts should open at 23 in-Hg. (584mm) and reclose at 20 in-Hg. (508mm).
