Start-Up Procedure
1. Make sure the correct amount of filter media is located in the tank and all connections have
been connected and secured.
2.
Press downward and rotate the Multiport Control Valve handle to the
‘BACKWASH’ position.
To
prevent damage to control valve seal, always depress handle before turning.
3. Start the pump according to the pump instruction manual (be sure all suction and return lines
are open), allowing the filter tank to fill with water.
Once water is flowing 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 particles in the media.
4. Turn the pump off and set the control valve to
‘RINSE’ position. Start the pump and operate until
water in sight glass is clear, which will usually take approximately 1 minute. Turn pump off and
set valve to
‘FILTER’ position and restart pump. The filter is now operating in the normal filter
mode, filtering dirt particles from the pool water.
5. Adjust pool suction and return valves to achieve desired flow. Check system and filter for water
leaks and tighten connections, bolts, nuts as required.
6. Take note of the initial pressure gauge reading for future reference. Variation may occur from
pool to pool.
NOTE THE INITIAL PRESSURE GAUGE READING WHEN THE FILTER IS CLEAN.
It will vary from pool to pool depending upon the pump and general piping system.
As the filter removes dirt and impurities from the pool water, the accumulation of dirt in the filter will
cause the pressure to rise and diminish the water flow. When the pressure gauge reading is 10 PSI or
70kPa, higher than the initial "clean" pressure you noted, it is time to backwash the filter (see
BACKWASH function).
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.
