SECTION VII. WINTERIZING THE FILTER
1. In areas that have freezing winter temperatures, the pool
equipment must be winterized to protect it from damage.
2. With the pump turned off, open the High Flow™ manual
air relief valve.
3. Remove the drain port cap, and allow the filter to drain
completely.
4. Remove the drain port plugs on the pump and allow the
pump to drain completely.
5. Drain all appropriate system piping.
6. It is recommended that the pump and filter be covered with
a tarpaulin or plastic sheet to inhibit deterioration from the
weather.
DO NOT WRAP THE PUMP MOTOR WITH PLASTIC.
7. Your filter system is now winterized.

RESTART, when pool is ready to be opened for the season.
SECTION VIII. 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 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 4.
4. Clean the debris from the valve stem and body. Verify that the filter tank’s air passage is opened by
inserting a 5/16" drill bit through the valve body. Verify 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.
