Figure 7: Coalescing Oil Removal Filter
Each kit includes one replacement filter element, one filter element
O-ring, and one filter bowl O-ring (refer to Figure 7). To replace the filter
element, proceed as follows:
1. Remove the service bypass valve locking pin, and push the plunger to
the right into the bypass position. Doing so will unload the pressure
in the filter bowl.
2. Disconnect the drain tubing.
3. Depress the lever on the filter bowl clamp, and turn it 1/8 revolution
in either direction. Drop the metal bowl guard and bowl to expose the
filter element.
