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.
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.
INST ALLA TION LOCA TION
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.
GENERAL PLUMBING
FOR SOLVENT WELD CONNECTIONS
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.
Recommended Adhesives-These are examples only and are
not intended to restrict brands.
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 DIFFICUL T AND MA Y
CAUSE DAMAGE.
Remove bag of miscellaneous parts and proceed as
follows:
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.)
Diverter
or basket
PVC-PVC Joint PVC-ABS Joint
Uni-Weld Pool-Tite 2000 Uni-Weld Pool-Tite 2000
Suregard Flex 20 Suregard Weld-All No. 5
IPS Weld-On 705 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
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.
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 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.
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.
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
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.
(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.
7. Set dial valve to FILTER and restart pump.
WATER CHEMISTR Y
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.
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.
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
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.
3. Observe the waste water. STOP pump when flow
becomes milky clear (approximately one to three
minutes).
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.
5. Set dial to FILTER and start pump to resume filtering operation.
Do not use pool vacuum cleaner when filter is
backwashing.
WINTERIZING
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:
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.
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.
