WINTERISING & PUMP DISASSEMBLY • Active Winterising : An actively winterised pool continues to operate at a slower than normal rate throughout wintertime. This is the recommended winterising procedure in less cold regions. If you live in a harsher winter climate, you should choose to passively winterise your pool instead.

CAUTION : ALWAYS CUT THE ELECTRICAL POWER UPSTREAM OF THE FILTRATION UNIT FIRST • Undo the 2 bleed screws to drain the water from the pipes and prevent a siphon forming. • Unscrew the pump inlet and outlet unions. • Wait for the water to drain through the hole in the bottom of the tank.
TROUBLE SHOOTING FILTERS/PUMPS/CCS PROBLEM : Low pressure flow and/or air bubbles in the pumped water flow CAUSE SOLUTION • SITUATION 1: The cartridges are dirty but not clogged. Clean the cartridges at more regular intervals (once every fortnight) •SITUATION 2: Renew the cartridges if they are clogged Cartridges •SITUATION 3: If you are using a flocculent or anti-algae treatment, lower the water level by 20 cm and renew the cartridges Clean the debris from the baskets at regular intervals and clean or renew the Netskims (skimmer socks/nets)
