Sullair Industrial Air Compressor 1809V AC

Warning: This procedure requires trained personnel with PPE!

Is the service air pressure approximately 1 psi over rated pressure?

Did you turn the inlet valve regulator adjusting screw until air just begins to escape from the control air orifice?

Did you lock the adjusting screw in place with the locknut?

Is the regulator now properly set?

The compressor unit and motor are rigidly connected via a mounting adapter housing.

This arrangement makes coupling alignment unnecessary.

The coupling is a jaw type in shear. If the elastomeric element requires replacement due to wear or breakage, order replacement element no. 02250152-669, and follow the following steps:

1. Remove the protective grill from the adapter housing.

2. Loosen the retaining screw located on the outer sleeve. Slide the sleeve to one side, exposing the coupling element.

3. Unwrap the coupling element from the coupling jaws.

4. Install the new element by wrapping it around the jaws, engaging the cogs on the element into the jaws.

5. Reinstall the outer sleeve and torque the securing screws to 10 in·lb (1.13 N·m). Install the protective grill.;

Warning: HIGH-PRESSURE HAZARD! DO NOT remove caps, plugs, and/or other components when compressor is running or pressurized. Stop compressor and relieve all internal pressure before doing so. Failure to comply could result in death or serious injury.

Fluid level in the separator/sump tank is sufficient

If fluid level is low, enter the amount of fluid added

Is the addition of fluid becoming too frequent?

If the addition of fluid becomes too frequent, refer to Section 6.9: Troubleshooting—Introduction on page 61 under EXCESSIVE COMPRESSOR FLUID CONSUMPTION for a probable cause and remedy.

Warning: This procedure requires trained personnel with PPE!

Regulator and solenoid valve(s) are protected by a strainer?

If not, report the issue to the maintenance team and stop the procedure

Hex cap from the strainer removed?

If the screen is damaged, the strainer assembly must be replaced (P/N 241772)

The fluid return/sight glass subassembly is attached to the side of the separator tank.

Fluid return/sight glass maintenance should be performed on a routine basis parallel to that of the fluid filter, or as indicated in Section 6.9: Troubleshooting—Introduction on page 63.

The maintenance on a fluid return/sight glass is mainly concerned with the condition of the filter assembly. Order filter assembly No. 02250117-782, and use the following instructions as a guide.

1. Disconnect the tube at the bottom of the sight glass.

2. Unscrew the sight glass assembly where the elbow fitting joins the strainer/filter.

3. Remove used filter assembly, and replace with new assembly.

4. Inspect and clean the orifice inside the sight glass blocks. The orifice must be removed with an Allen wrench.

5. Coat/lubricate the O-rings with silicone grease.

6. Reattach the connectors to the sight glass/orifice blocks.;
