FILTERING

Filtration starts as soon as flow is steady through the 
filter.  As the filter cartridge removes dirt from the pool
water, the accumulated dirt causes a resistance to flow.
As a result, pressure will rise and the flow will decrease.
When flow  decreases below desired rate, clean or replace
the filter cartridge.

CLEAN/REPLACE CARTRIDGE

Removing Cartridge Element

Shut off the pump.

Block off suction and discharge lines (close valves if
used) to prevent back flow of water from pool.

Open top air relief valve and remove drain valve to
allow water to drain from filter.

Unscrew union nut, freeing filter from rigid union
connection.

Hold filter head firmly and unscrew filter housing to
remove.  If difficult to unscrew, apply a lever between
the two tab extensions on the bottom of the filter
housing and apply a slight pressure to assist in
freeing the thread seal.  Or, apply optional S200KT
wrench (if supplied) to bottom side tabs.

Remove cartridge element and clean.  Or, replace
with clean, spare cartridge.  (See Cleaning Cartridge)
