Before installation be sure to read all instructions and warnings carefully. Refer to product label(s) for additional operation instruction and specifications.
INSPECTION
Examine the equipment when received. Notify your dealer or carrier of any damage or missing parts. Verify that equipment is of size and model specified.
INSTALLATION LOCATION
Locate unit on a solid foundation as close to pool/spa as possible. Give consideration to drainage-away from equipment, ventilation, and access for future servicing and winterizing.
PUMP SELECTION
A full line of pool/spa pumps are available for installation with these filters. For those installations where the equipment will be placed above the water level, a self-priming pump should be selected. Ask your dealer to determine the proper size and distance from pool or spa and friction losses (restrictions) of associated equipment.
FOR THREADED CONNECTIONS
Use only Teflon ® tape or equivalent on threaded plumbing connections. Other pipe compounds may damage threads. We do not recommend the use of silicone or petroleum based compounds. DO NOT
OVERTIGHTEN: HAND TIGHTEN PLUS 1/2
TURN IS SUFFICIENT.
FILTER PLUMBING
If filter is equipped with union connections, union adapters are needed to complete plumbing connections and may need to be ordered separately.
SAND FILTER PREPARATION
DO NOT PLACE SAND IN FILTER TANK BEFORE
IT IS POSITIONED AS ITS WEIGHT WILL MAKE
MOVING TANK MORE DIFFICULT AND MAY
CAUSE DAMAGE.
Remove bag of miscellaneous parts and proceed as follows:
GENERAL PLUMBING
FOR SOLVENT WELD CONNECTIONS
1. Remove diverter/basket. Inspect the standpipe system to assure that it is properly assembled. (Press firmly on the standpipe to make sure that it is securely seated at the bottom of the tank.)
Rigid or flexible PVC pipe can be used. Pipe ends should be clean and free of any flash caused by the cutting operation. Be sure that the proper adhesive is used on the type of pipe specified.
Diverter or basket
Recommended Adhesives-These are examples only and are not intended to restrict brands.
PVC-PVC Joint
Uni-Weld Pool-Tite 2000
Suregard Flex 20
IPS Weld-On 705
PVC-ABS Joint
Uni-Weld Pool-Tite 2000
Suregard Weld-All No. 5
IPS Weld-OM 794
Note: A primer will assure that adhesive joints are superior.
Suregard P-3000 has a purple tracer to qualify in areas where codes specify a primer must be used.
Caution: We recommend that you consider climatic conditions when applying adhesives. Certain atmospheric situations, such as high moisture content, make the adhesive action of certain glues less effective. Check the manufacturer’s instructions.
2. Place standpipe cover on standpipe to prevent entrance of any sand. Standpipe cover is either a plastic cap or waxed corrugated assembly found in misc. parts bag or separately in carton. Some filters may already have standpipe cover installed on standpipe and diverter removed and located in misc.
parts bag.
3. Fill tank approximately 1/2 full of water.

4. Add sand (not provided) following recommendation for size and amount on product label. Be sure that standpipe remains centered while pouring sand. Be sure sand is level.
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.
Standpipe cover or fill spout
Sand Level
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.
5. Remove cover from standpipe.
6. Place diverter/basket back on standpipe for all tanks.
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.
7. Carefully remove all sand particles from valve mounting location, being especially careful of valve bolt inserts and O-ring seat.
RINSE - (6 and 7 position dial valve only, not available 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.
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.
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 maintenance if filter is below water level.
FILTER START UP
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.
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.
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.
3
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.
(cont’d next page)
6. If your dial valve does not have a RINSE cycle, proceed to STEP 7. If your dial valve does have a
RINSE cycle, set it to that position, restart pump and allow it to run 20 seconds. STOP pump.
3. Observe the waste water. STOP pump when flow becomes milky clear (approximately one to three minutes).
7. Set dial valve to FILTER and restart pump.
4. If your dial valve does not have a RINSE cycle proceed to step 5. If your dial valve does have a
RINSE cycle, set it to that position, restart pump and allow to run 20 seconds. STOP pump.
WATER CHEMISTRY
Proper and consistent use of chemicals is necessary to maintain clean, sanitary water, prevent a spread of germ infection and control the growth of algae which can spoil the appearance and enjoyment of your pool or spa.
5. Set dial to FILTER and start pump to resume filtering operation.
Do not use pool vacuum cleaner when filter is backwashing.
WINTERIZING
Chlorine is the most commonly used chemical to provide clean, sanitary water. Either dry or liquid chlorine can be used which should be added daily as it is dissipated by dirt and germs as well as by the sun and wind.
Consult your dealer for advice on winterizing your equipment if freezing temperatures occur in your locality. Their knowledge of your equipment makes them the best qualified source of information. Follow their recommendations, and if these include draining the filter system, proceed as follows: It is also important that the correct level of acidity or alkalinity of the pool water be maintained. This is the pH of your pool with pH 7.0 being neutral. Readings above pH 7.0 are alkaline and readings below are acid.
A desirable range is 7.2 to 7.4. Consult your local pool/spa dealer for complete information on proper application and use of chemicals.
FILTER MAINTENANCE
1. BACKWASH for 3 to 5 minutes and the set dial valve to WINTERIZE position.
2 Drain system by removing drain plugs and/or removing pipe caps from the filter, pumps, and disinfecting equipment. Store plugs in a dry place for safekeeping.
Filter tank and contents should not require attention other than backwashing provided water is kept in continuous chemical balance without heavy dosages of corrosive chemicals.
CLEANING FILTER (Backwashing)
When the new filter is first placed in service, note reading on pressure gauge. As dirt builds up in filter, the pressure reading will increase. When it reads 10
PSI above the original reading, it is time to backwash as described below.
1. STOP pump.
2. Set dial valve to BACKWASH and start pump.
