4.Do not locate the PuraGuard QC™ filter near heat producing components such as the vehicle exhaust and provide adequate clearance from moving components e.g. drive shaft, suspension, pitman arm, etc.
5. Locate the PuraGuard QC™ filter on the vehicle so that a minimum of 12 inches of clearance is available horizontally (90° minimum arc) to allow servicing. This will permit a strap wrench to be used when replacing the filter.
6.Be sure that there is sufficient room to attach hoses to the PuraGuard QC™ filter.
7.To permit draining of collected contaminants, at least a 6 inch clearance below the filter is recommended. Nominal clearance above is required.
8.The PuraGuard QC™ oil coalescing filter must be installed after a properly functioning air dryer. Failure to locate the filter after an air dryer can cause the filter to malfunction. An air dryer eliminates certain conditions in the discharge line that could compromise the design of the filter.
9.Do not mount the unit in the engine compartment.
MOUNTING THE PURAGUARD QC™ OIL COALESCING FILTER

2.Hoses must be installed without tight turns that might cause air flow restrictions. Note: Check that the hose attachment agrees with the air flow arrow symbol (see Figure 1).
OPERATIONAL TEST
Build the air system to governor cutout. Shut off the engine. Using a soap solution, check all hoses and fittings leading
to and from the filter for leakage and integrity. Repair any excessive leaks - exceeding a 1 inch bubble in 5 seconds - before restoring vehicle to service.
