4. Add sand (not provided) following recommenda-
tion for size and amount on product label. Be sure that
standpipe remains centered while pouring sand. Be
sure sand is level.
5. Remove cover from standpipe.
6. Place diverter/basket back on standpipe for all
tanks.
7. Carefully remove all sand particles from valve
mounting location, being especially careful of valve
bolt inserts and O-ring seat.
8. Position O-ring carefully in groove on tank top or
on bottom of dial valve.
9. For all tanks except the SandStorm, install dial
valve on tank, using provided hex bolts. Tighten bolts
uniformly, being careful not to OVERTIGHTEN. Port
position on valve should be relative to pump location.
Note: Six position dial valves are equipped with sight
glass which must be hand tighten only.
10. For SandStorm tanks, install dial valve using
provided v-band clamp. Insure that the tank flange and
dial-valve flange are enclosed within the clamp before
tightening. Port position on valve should be relative to
pump location.
11. Install pressure gauge.
12. For Laser filters or filters that include a backwash
adapter - the reduced orifice 1-1/2” thread x barb
backwash adapter in the hardware kit is designed to
provide proper water flow during the backwash cycle.
To insure desired backwash characteristics install the
adapter in the waste port of the dial valve.
DIAL VALVE FUNCTIONS
FILTER - For normal filtering. This position also can
be used for regular vacuuming.
BACKWASH - Clean your filter with this position.
Note instructions on Cleaning Filter.
DRAIN - This position allows you to pump water
from the pool. The flow from the pump is permitted to
bypass the filter and go directly to waste. Use this
position to vacuum heavy concentration of debris.
WHIRLPOOL - By bypassing the filter, this position
creates more pressure to obtain optimum performance
from any hydro-therapy fittings. No filtration occurs
while the valve is in this position.
WINTERIZE - This is a neutral position which is
used only when pump is stopped. It allows air to
leave-or enter the tank to help priming and draining.
RINSE - (6 and 7 position dial valve only, not avail-
able on 4 position dial valve). For settling filter bed
after backwashing and for carrying any remaining
loose dirt to waste. The rinse prevents any return of
residual dirt to the pool that occurs momentarily when
changing directly from BACKWASH to FILTER.
TEST - (6 and 7 position dial valve only, not available
on 4 position dial valve) This position prevents any
backflow of water from pool during pump mainte-
nance if filter is below water level.
FILTER START UP
1. Set dial valve to DRAIN position.
2. Perform pump start up.
3. After good flow has been established, continue
pumping for one minute or until wastewater is clear.
4.. Stop the pump. Set dial valve to BACKWASH and
restart pump.
5. Observe the waste water. When flow becomes
clear (approximately 2 to 3 minutes). STOP pump.
