How to replace the FRP-001 or FRP-007 filter kit.

1. Power down the unit and confirm that the pressure reading on the gauge above the filters reads 0 PSI.
2. Disconnect the drain lines from the filter bowls by pushing the orange rings towards the filter bowl, while pulling down on the poly lines.
3. Unscrew the filter bowls by hand by rotating the outer metal casing clockwise.
4. Pull down on the plastic filter bowls to remove them from the upper filter housing taking care to remove the O-rings.  The O-rings can be discarded.
5. The black filter element on the left can be removed from the upper filter housing by rotating clockwise and discarded.
6. The white filter element on the right can be removed from the plastic filter bowl by gently prying up on the black upper filter assembly with the O-ring removed.   Once removed from the filter bowl, rotate the lower piece of the filter assembly a quarter turn counter clockwise.  The white element can be discarded and replaced and then reassembled.
7. Fill the plastic filter bowl about half way with warm soapy water and shake with your hand covering the top opening.  Repeat for both bowls.  This will ensure that the float drain is clean and operational.
8. Remove and replace the O-rings on the lip of the plastic filter bowl.
9. Install the outer metal casing back onto the plastic filter bowl, taking care to line up the protrusion on the bottom with the opening in the metal casing.
