FIGURE 3 - PURAGUARD QC™ OIL COALESCING FILTER INSTALLATION SYSTEM WITH AIR DRYER

The PuraGuard QC™ oil coalescing filter has two female pipe thread air connections: one supply, one delivery — identified by their relationship to the arrow symbol showing air flow on the PuraGuard QC™ filter top (see Figure 1).

Note: The PuraGuard QC™ filter is not recommended to be used in conjunction with an alcohol evaporator or injector. The PuraGuard QC™ oil coalescing filter will remove the liquid or aerosol alcohol introduced, defeating the purpose of the evaporator/injector and requiring the sump to be drained more often than normal.

FILTER BYPASS (refer to Figure 4)

If a situation occurs where the ability of the filter to allow air to pass is impaired and causes a pressure difference of approximately 20 p.s.i. between the air entering the filter element and exiting, the filter will move downward against the spring. The air entering will then be able to bypass the filter element.

PREVENTIVE MAINTENANCE

Important: Review the warranty policy before performing any intrusive maintenance procedures. An extended warranty may be voided if intrusive maintenance is performed during this period.

Because no two vehicles operate under identical conditions, maintenance intervals will vary. Experience is a valuable guide in determining the best maintenance interval for a vehicle.

Every 300 operating hours, 8,000 miles or one (1) month:

1.With the air system pressure at 0 p.s.i., use the drain valve to collect contaminants for disposal. Do not open the valve beyond shoulder stop. This could loosen the handle.

2.Visually check the PuraGuard QC™ filter for broken or missing parts.

3.Check mounting bolts for tightness. Re-torque to vehicle manufacturers guidelines.

4.Perform the Operation & Leakage Tests listed in this publication.

Every 3,600 operating hours, 100,000 miles or one (1) year:

1.With the air system pressure at 0 p.s.i., drain collected contaminants for disposal.

2.Visually check for physical damage to the PuraGuard QC™ filter such as chaffed or broken air hoses and broken or missing parts.

3.Replace the cartridge (see Maintenance Kits, Figure 5). Do not use the drain valve to remove the cartridge.

4.Check mounting bolts for tightness. Re-torque to 160- 200 in-lbs.

5.Perform the Operation & Leakage Tests listed in this publication.
