Cleaning the High Flow™ Manual Air Relief Valve

1.Turn the pump off and shut off any automatic controls to ensure that the system is not inadvertently started during servicing.

2.OPEN THE HIGH FLOW™ MANUAL AIR RELIEF VALVE UNTIL IT SNAPS INTO THE FULL OPEN POSITION, THEN WAIT UNTIL ALL PRESSURE IS RELIEVED.

3.With the High Flow™ manual relief valve attached to the filter tank, pull out the locking tabs and remove the valve stem and cover assembly with a counter-clockwise and lifting motion, see Figure 3.

4.Clean debris from the valve stem and body. Ensure that the filter tank's air passage is open by inserting a 5/16 in. drill bit through the valve body. Ensure that the o-rings are in good condition, properly positioned, and lubricated with a silicone base lubricant.

5.Reinstall the valve stem and cover assembly with a downward and clockwise motion until it snaps into position.
