USE ONLY HAYWARD GENUINE REPLACEMENT PARTS 5
INITIAL START-UP OF FILTER
1. Be sure correct amount of filter sand media is in tank and that all connections have been made and are secure.
IMPORTANT: To prevent unnecessary strain on piping system and valves, always shut off pump before switching Filter
Control Valve positions.
2. Depress Vari-Flo control valve handle and rotate to BACKWASH* position. (To prevent damage to control valve seat,
always depress handle before turning.)
3. Prime and start pump according to pump instructions. (be sure all suction and return lines are open), allowing the filter
tank to fill with water.
WARNING – All suction and discharge valves must be open when starting the system. Failure
to do so could cause severe personal injury and/or property damage.
4. Once water flow is steady out the waste line, run the pump for at least 2 minutes. This initial backwashing
of the filter is recommended to remove any impurities or fine sand particles in the sand media.
5. Turn pump off and set valve to RINSE position. Start pump and operate until water in sight glass is clear—
about 1/2 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 from the pool water.
6. Adjust pool suction and return valves to achieve desired flow. Check system and filter for water leaks and tighten
connections, bolts, and nuts, as required.
7. 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.) (Line up green arrow on gauge to clean pressure.) As the filter removes dirt and impurities
from the pool water, the accumulation in the filter will cause the pressure to rise and flow to diminish. When the pressure
gauge reading is 6-8 PSI (0.41-0.55 BAR) higher than the initial "clean" pressure you noted,(Red Arrow on Gauge) it is time
to backwash (clean) the filter (see BACKWASH under Filter Control Valve Functions).
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.
To prevent damage to the pump and filter and for proper operation of the system, clean pump strainer and skimmer baskets
regularly.
FILTER CONTROL VALVE FUNCTIONS
FILTER—Set valve to FILTER for normal filtering. Also use for regular vacuuming.
BACKWASH—For cleaning filter. When filter pressure gauge rises 6-8 PSI (0.41-0.55 BAR) above start-up
(clean pressure): Stop the pump, set valve to BACKWASH. Start pump and backwash approximately 2
minutes or less depending on dirt accumulation until water in sight glass is clear. Proceed to RINSE.
RINSE—After backwashing, with pump off, set valve to RINSE. Start pump and operate for about 1/2 to 1
minute. This ensures that all dirty water from backwashing is rinsed out to the filter to waste, preventing
possible return to the pool. Stop pump, set valve to FILTER, and start pump for normal filtering.
WASTE—To bypass filter for draining or lowering water level and for vacuuming heavy debris directly to
waste.
RECIRCULATE—Water is recirculated through the pool system, bypassing the filter.
CLOSED—Shuts off flow from pump to filter.
VACUUMING—Vacuuming can be performed directly into the filter. When vacuuming heavy debris loads, set
valve to WASTE position to bypass the filter and vacuum directly out to waste.
WINTERIZING
1. Completely drain tank by unscrewing drain cap at base of filter tank. Leave cap off during winter.
2. Depress Vari-Flo control valve handle and rotate so as to set pointer on valve top between any two positions. This will allow
water to drain from the valve. Leave valve in this "inactive" position.
3. Drain and winterize pump according to pump instructions.
