WINTERISING
Winterising is preparing your pool for freezing conditions which can potentially damage all pool filtration
equipment due to water expanding when frozen. We highly recommend the following steps when
preparing your filter for winter conditions:
1. Backwash the filter for at least thirty minutes before closing down the pool for winterising. This
will clean the filter bed thoroughly and remove any debris from the system.
2. Drain the filter tank by removing the drain cap at the base of the filter tank. Leave the cap off
during winter.
3. Set the control valve handle between the RINSE and FILTER. This will lift the handle and help
with the draining process by allowing air to enter into the tank.
4. Unscrew the pressure gauge from the control valve and store the gauge indoors.
5. Drain and winterise the filter pump according to the manufacturer's instructions.
This is an ideal time for any repairs that may be required during the off-season. Most pool professionals
will recommend want is needed before the next pool season.
