START-UP PROCEDURE

1/ Be sure the correct amount of filter sand media is in the
tank and all connections have been made and are secure.
2/ Turn the Control Valve handle to the "Backwash"
position. Press the handle downward before turning.
3/ Start the pump according to pump instruction manual (be
sure all suction and return lines are open).
4/ Once water flow is steady out the waste line, run the pump
for at least 2 minutes. The initial backwashing of the filter is
recommended to remove any impurities or fine sand
particles in the sand media.
5/ Turn the pump off and set the control valve to RINSE
position. Start pump and operate until water in sight glass is
clear about ½ to 1 minute. Turn pump off, set valve to
FILTER position and restart pump. Your filter is now
operating in the normal filter mode, filtering particles and
dirt from the pool water.
6/ Take note of the initial pressure gauge reading for future
reference. Variation may occur from pool to pool.
7/ Adjust pool suction and return valves to achieve desired
flow. Check system and filter for water leaks and tighten
connections, bolts, nuts as required.
NOTE: During the initial clean-up of the pool water, it
may be necessary to backwash frequently due to the
unusually heavy initial dirt load in the water.
IMPORTANT: To prevent unnecessary strain on piping
system and control valve, always turn off the pump before
changing the operation of the control valve. To prevent
damage to the pump and filter and for proper operation of
the system, clean pump strainer (basket) and skimmer
basket(s) regularly.
MULTIPORT CONTROL VALVE FUNCTIONS:-
FILTER gives downward flow through the filter bed. This
position can also be used for vacuuming.
BACKWASH gives upward flow through the filter bed that
removes the dirt from the sand and carries it to the waste.
WASTE is for pumping water from the pool. It allows the
flow from the pump to bypass the filter and go directly to the
waste. You can also use this position to vacuum heavy
concentration of debris.
RECIRCULATE bypasses the filter to circulate water
through the pool system.
RINSE gives a downward flow that settles the filter bed
after backwashing and carries any remaining loose dirt to
the waste.
CLOSED prevents only backflow of water from pool during
pump maintenance.
To WINTERISE, set the control valve handle in the middle
between RINSE and FILTER. This will allow air to leave or
enter the tank to help priming and draining. Only to be used
when the pump is off.
VACUUMING THE POOL
Light Soil: set the control valve to FILTER position.
Heavy Soil: set the control valve to WASTE position.
