SECTION VI.
WINTERIZING THE FILTER.
1. In areas that have freezing winter temperatures, the pool equipment must be winterized to protect it from damage.
2. Backwash the filter. Shut off the pump and set the control valve to the winterize position.
3. Remove the drain port cap at the bottom of the filter.
Remove drain port cap only for draining water from filter. Removing the entire fitting will allow sand to drain also. Do not
remove the entire fitting on the 18 " filter. This will damage the filter. The filter will drain slowly. Leave the drain port cap
off and store it during the time the system is shut down.
The control valve should be left in the winterize position during the shutdown season so that the rubber seal of the valve diverter
has no pressure on it. Failure to do so can damage the valve diverter seal which can cause property damage from leaking water.
4. Drain all appropriate system piping.
5.
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 pump motor with plastic.
SECTION VII.
EQUIPMENT MAINTENANCE.
A. AIR ENTERING YOUR FILTER IS DANGEROUS AND CAN CAUSE THE LID OR VALVE TO BLOW OFF.
1. Correct any conditions in your filtration system that allow air to enter the system.
2. Some common ways to identify air entering the system are:
a.
Low water level in pool or spa - skimmer is starving for water with pump running. Add water to pool or spa.
b.
Air bubbles or low water level in pump hair and lint pot are caused by: Low water level, clogged skimmer basket, split
suction cleaner hose, leak in pump hair and lint pot lid, or leak in pump suction line.
c.
Air bubbles coming out of water return lines into the pool or spa with pump running, see Steps 2.a. and 2.b. above.
d.
Air is discharged from the High Flow™ manual air relief valve on top of the filter when the valve is opened with the
pump running, see Steps 2.a. and 2.b. above.
B. THE PRESSURE GAUGE IS YOUR PRIMARY INDICATOR OF HOW THE FILTER SYSTEM IS OPERATING.
1.
It is an important part of your filter system.
2. Maintain your pressure gauge in good working order.
3. Check the operation of your pressure gauge in the following manner:
a.
The pressure gauge should go to zero (0) when the system is turned off and pressure is relieved.
b.
The pressure gauge should indicate pressure when the system is operating.
c.
The pressure gauge should be readable and not damaged in any way.
d.
Replace the pressure gauge if any of the above conditions exist.
