MAINTENANCE

Cleaning the Separation Tank

The following information should be read carefully since it outlines the proper manner of care and operation for your filter
system. As a result of following these instructions and taking the necessary preventative care, you can expect maximum
efficiency and life from the filter system.
Please heed all manufacturers' posted instructions, warnings and cautions when using polyhexamethylene biguanide
sanitizers or other filter cleaning solutions.
1. Turn the pump off, 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, (and the waste drain valve, or cap, if your system has one).
3. Remove hair and lint strainer pot lid and clean basket. Replace basket and secure lid.
4. Open the drain valve and wait for the water to drain from the Sep 100
containing D.E. and contaminants.
5. Remove locking ring by depressing safety latches on both sides of ring and rotate counterclockwise, then remove tank
lid.
6. Remove the separation bag by pulling straight up on the bag handle loop.
7. Dispose of waste in trash and rinse bag clean. Inspect bag for holes - replace if necessary.
8. Clean and remove debris from inside the filter tank and from the O-ring and O-ring groove on the tank body.
9. Install the clean bag into the tank assembly making sure it is seated onto the separation tank ring.
10. Replace the tank lid onto the tank body making sure it is fully and firmly seated on the tank body.
11. Place lock ring over tank lid, and centering the lock ring on the threads of the tank body, turn the lock ring
clockwise until the safety latches click and the lock ring hits the stops on the body. DO NOT ATTEMPT TO OVER-
TIGHTEN THE LOCK RING AFTER LOCK RING HAS HIT THE STOPS ON THE BODY.
Note: Any time the separation tank is opened, and/or separation bag is removed, be sure to generously coat the
O-ring with silicone lubricant before reassembling the unit. DO NOT USE PETROLEUM BASED LUBRICANTS
BECAUSE THEY HAVE A DETERIORATING EFFECT ON RUBBER.
12. Replace drain cap and reinstall manual air relief valve drain hose if used.

Cleaning the 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 relief valve attached to the filter tank, pull out the locking tabs and
remove the valve stem and cover assembly with a counterclockwise and
lifting motion, see Figure 3.
4. Clean debris from the valve stem and body. Verify that the filter tank's air
passage is open by inserting a 5/16 in. drill bit through the valve body. Verify
that the O-ring 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.
