CHAPTER 4: INITIAL STARTUP OF FILTER
Recheck that all the connections have been made
and are secure, and that the lter media was added
to the tank.
1. Depress Multi-Port Valve handle and rotate to the
BACKWASH position. NOTE: To prevent damage
to control valve seal, always depress handle
before turning.
2. Switch on the Pump. Open the Inlet Valve allowing
the Sand Tank to ll with water. CAUTION: All
suction and discharge valves must be open
when starting the pump. Failure to do so could
cause severe personal injury and/ or property
damage. NOTE: If a pump is installed, switch the
pump on and off, instead of closing and opening
the Inlet Valve.
3. Once water ow is steady out the waste line, run
the pump for at least one minute. The initial
backwashing of the lter is recommended to
remove any impurities or ne sand particles in the
lter media.
4. Turn the pump off. Set the Multi-Port Valve to the
RINSE position. Switch on the Pump. Open the
Inlet Valve until water in sight glass is clear -
approximately 10 to 15 seconds.
5. Switch off the Pump. Close the Inlet Valve, set the
Multi-Port Valve to the FILTER position and Switch
on the Pump. Open the Inlet. Your lter is now
operating in the normal lter mode.
6. Adjust pool suction and return valves to achieve
desired ow. Check the plumbing and lter for water
leaks and tighten connections, bolts, and nuts, as
required. NOTE: During 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.
7. Record the pressure gauge reading (start up
pressure) during initial operation. After a period
of time, the accumulated dirt and debris in the lter
causes a resistance to ow, and the ow diminishes.
The pressure will start to rise and the ow of
water will start diminishing. When the pressure
gauge reading is 8-10 PSI higher than the
initial “Start up” pressure, it is time to backwash
(clean) the lter (see Backwashing). NOTE: To
prevent unnecessary strain on piping system
and valving, always shut off the pump before
switching lter control valve position. To
prevent damage to the pump and lter and
for proper operation of they system, clean
pump strainer and skimmer baskets regularly.
