Servicing
Removing Diverters for Inspection or Service
1. Shut off the pump and open the manual relief valve on
the filter to relieve all internal pressure.
2. If the filter is below the pool water level, close the
suction and the return line valves to isolate the filtration
equipment.
3. Drain the filter by moving the valve handle to the
backwash position and removing the filter drain plug.
4. Remove the handle by firmly pulling the handle straight up.
5. Pull the tabs (if needed, insert two flat head screwdrivers
behind the tabs) and rotate the top counter-clockwise
to unlock. Remove the end cap.
6. Slowly pull out the diverter assembly.
Note which diverter is on the top before reassembling.
Cleaning and/or Replacing the Diverters
1. DOW CORNING
®
111 LUBRICANT or similar lubricant
is recommended as a seal lubricant.
Note: This lubricant is formulated to seal surfaces and
extends the lubrication period. Many other lubricants
are broken down quickly by pool water and have a short
lubricating life.
2. Inspect all seals for nicks and cuts. Replace diverter
if damaged.
3. Inspect the bore of the valve especially around the
ports. Deep scratches and cuts in this area may cause
leaks from the waste port. Replace valve if damaged.
4. Using a clean cloth, thoroughly clean all seals and the
bore of the valve.
5. Apply liberal amounts of DOW CORNING
®
111
LUBRICANT or similar lubricant to the surface of all
seals.
Use only use silicone based lubricants on the valve, other types of lubricant may damage the plastic or rubber components.
Incorrect assembly of the internal components may cause your filter to dead head and could cause severe bodily and/or property
damage.
