Cleaning the Manual Air Relief Valve
1. Turn the pump and any automatic controls off 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 and wait until all
pressure is released from the system.
3. With the manual air relief valve attached to the Quad
D.E.
®
Cartridge Style Filter tank, pull out the locking
tabs and remove the valve stem and cover assembly
with a counter-clockwise and lifting motion (see
Figure 5
).
4. Clean debris from the valve stem and body. Insert
a 5/16” drill bit through the valve body to ensure the
filter tank’s air passage is open.
5. Be sure the O-rings are in good condition, properly
positioned, and lubricated with a silicone base
lubricant.
6. Reinstall the valve stem and cover assembly with a
downward and clockwise motion until it snaps into
position.

Cleaning the Internal Air Bleed Tube
It is recommended that the air bleed tube and screen
cap be routinely inspected and cleaned. This can easily
be done while the filter lid has been removed for routine
maintenance or cleaning.
Remove the screen cap from the air bleed tube and
rinse both components with water to clean away built-
up debris. Typically, this is all that is needed to properly
clean the air bleed assembly.
