CLEANING A VU-FLOW SCREEN TYPE FILTER

The Vu-flow is a centrifugal / screen type filter that is intended to trap hard particles of sand or mica. The particles drop to the bottom and can be purged out by turning the knob on the bottom of the filter. Occasionally the screen itself will become fouled with a sticky iron or clay like material. When this happens the screen must be removed to be cleaned. To do this:

1. Before you turn the water off, put some water in a small bucket or pan. You will need a small amount of bleach for this procedure and a small brush.

1. Turn the water off before and after the filter by turning the ball valves to the closed (perpendicular) position.

2.  Depressurize the filter by turning the knob on the bottom, with the tube in a bucket. If there is no tube attached to the bottom of the filter, hold the bucket close.

3.  Unscrew the bottom (clear) sump.

4.  Remove the filter element by pushing it to the side.It is held in by an o-ring, and is not threaded.

5.  Clean the filter element in a small bucket or pan using a toothbrush dipped in bleach.

6.  Reinstall the filter element by pushing it up into the space in the top of the filter cap.

7.  Make sure the filter sump still has its o-ring.  Holding the filter sump, pour in a small amount of household bleach (approx 1-2 tablespoons)., and re attach it to the cap of the unit, hand tightening only.

8.  Slowly repressurize by opening the ball valves and check for leaks.
