backs and barriers that must be followed.
ELECTRICAL
We recommend you have a qualified electrical contrac-
tor install the electrical power supply as specified in your
pump instructions.
INSTALLED LOCATION
Position filter, pump and any other related components
a minimum of 4 feet from pool to prevent their being
used as a means to climb into the pool by young chil-
dren. DO NOT store toys, chairs, tables, containers or
other objects within 4 feet of the pool for the same
reason.
WARNING
SEVERE ELECTRICAL SHOCK could result if you
install your filter and pump on a deck or above pool
water level. They could fall into the water, causing
severe shock or electrocution. DO NOT install on a
deck or other surface at, above or slightly below the top
rail of the pool.
PROPERLY SUPPORTED
Filter, pump and any other related components should
be properly supported to prevent damage from misalign-
ment, settlement, vibration and mounted so as to
minimize the potential for the accumulation of debris and
moisture.
ACCESSIBILITY
The circulation system components should be installed
to allow accessibility for inspection, repair or replace-
ment.
DO NOT alter the pump electrical cord in any way or
change the plug end to any style.
DO NOT use an extension cord(s). Severe electrical
shock may occur.
IMPORTANT SAFETY INSTRUCTIONS
PREVENT SEVERE SHOCK
To prevent the risk of severe electrical shock, plug your
pump cord end into a grounding type receptacle pro-
tected by a ground fault circuit interrupter (GFCI).
Contact a qualified electrician if you cannot verify that
the receptacle is protected by a GFCI.
DO NOT allow children to operate or play around this
product unless they are closely supervised by adults at
all times.
Replace damaged cord immediately to reduce the risk of
electrical shock.
DO NOT BURY CORD
An exposed cord may accidentally become damaged or
severed by a sharp object or shovel resulting in severe
electrical shock. Position cord to prevent accidental
damage from lawn mowers, hedge trimmers or other
equipment.
BARE FEET/WET GROUND
This is a dangerous combination around electrical
equipment. Always be sure the ground under your feet
and body is dry before you touch electrical equipment.
Failure to heed this warning may cause severe personal
injury or electrocution due to severe electrical shock.
WARNING
Avoid direct water spraying with a garden hose around
electrical outlets, pump or any other electrical devices.
Severe electrical shock or electrocution may occur.
SERVICING YOUR PUMP

INSTALL FILTER SAND
Your filter is designed to provide peak performance
using #20 grade filter (.4/.5 mm) sand. The sand should
be uniform in size and appear as crushed sand with
sharp edges. Rounded river bed sand will impair
filtering performance. Consult your local pool store.
REMOVE COVER CLAMP
Turn tank clamp screws counter-clockwise to loosen
clamp and remove.
REMOVE COVER
Lift cover off tank. Remove large O-Ring.
COVER RISER TUBE
Slip a plastic bag over the riser tube and secure with
rubber band.
INSTALL SAND
Gently pour 150 lbs. of filter sand into tank and level
surface with palm of hand. Remove any sand from
plastic bag and tank flange sealing surface. Remove
rubber band and plastic bag.
REINSTALL COVER
Position large O-Ring on tank flange sealing surface and
place cover on top, aligning O-Ring into cover groove.
Install tank clamp, sandwiching cover and tank flanges.
Tighten tank clamp screws securely.
INSTALL HOSES
See Fig. 1 and Exploded Parts Illustration
IMPORTANT: Incorrect hose hook-up could cause
damage to your filter system. Follow the instructions
below carefully.
Suction and return lines should be partially buried to
prevent accidental tripping that could cause personal
injury or damage to the filter system.
Be sure the hoses are routed so that water flow through
them is not restricted.
Starting at least 12" from the pool wall, make two 3-4"
deep trenches, one from the pool skimmer to the front
of the pump, and the other from the pool return fitting to
the filter/valve return port.
The two 8 ft. long hoses (Items 6) are interchangable
and used for the suction and return lines. Slip a hose
clamp over the ends of each hose prior to installing.
Connect one long hose (suction line) between the pool
skimmer and front port of the pump. Connect the other
long hose (return line) between the pool return fitting
and the filter/valve port labeled "RETURN". Connect the
short hose (Item 28) between the pump discharge port
(located at top of pump) and the filter/valve port marked
"PUMP". Tighten clamps firmly using a flathead
screwdriver or 5/16" nutdriver. Cover the trenches with
a firm board when finished.
NOTE: Do not completely bury the hoses with dirt.

WASTE LINE HOOK-UP
The discharge waste water will contain pool water
treatment chemicals that may harm certain plants and
vegetation. Therefore, position the discharge end of the
waste line in a safe, out-of-sight area capable of accept-
ing 150 to 200 gallons of waste water. Remove the
union fitting (Item 14) and union plug (Item 15) from the
valve port marked "WASTE." (See exploded illustration)
Install the union hose adaptor(Item 13), onto the port,
and replace union nut. Install a 1-1/2" inside diameter
waste discharge hose (not supplied) onto the the hose
adaptor. Before installing hose, slip a 1-1/2" hose clamp
(not supplied) over one end of the hose. Then, push
hose fully onto the waste port and tighten clamp firmly.
ELECTRICAL OUTLET
Refer to your pump owners guide for detailed informa-
tion pertaining to the requirements and regulations for
safe electrical installation of the power supply, recep-
tacle outlet, switching and ground fault interrupter.
FINISH FILLING POOL
Finish filling your pool, referring to skimmer installation
and pool assembly instructions for proper water level.
VALVE OPERATION
Your new filter has six positions of operation, which are
explained below. To change positions of the valve,
make sure the pump is OFF. Press down on the valve
handle enough to free the locking tab. Rotate the
handle so the tab LOCKS in the desired position.
FILTER: Normal pool filtering position. May also be
used when vacuuming the pool.
BACKWASH: Backwashing reverses the flow of water
through the filter to flush out dirt and debris, and waste
water is discharged to waste from the valve body port
marked "To Waste". (Duration is normally 1-1/2 to 2
minutes or until water runs clear.)
FILTER TO WASTE: Place the valve handle in the
“Filter to waste” position after backwashing your filter.
(Normally, for only 10 seconds).
PUMP TO WASTE: This position allows you to vacuum
heavy debris or larger amounts of settled contaminants
from the pool floor directly to waste.
RECIRCULATE POSITION: This position allows you to
increase the water flow rate to circulate chemicals
throughout the pool more quickly. Pool water passes
through the valve on top of the filter bypassing internal
filter components and travels back to the pool at a rapid
rate.
WINTERIZE POSITION: This position allows you to
drain trapped water from the filter valve and relieve
compression on the rotor valve gasket during winter
storage. CAUTION: Do not operate pump in this
position as waste water contaminants will be discharged
from the filter back into the pool.
(Normally, for only 10 seconds).
INITIAL START UP
Before you begin filtering your pool, the filter sand must
be backwashed thoroughly to remove the extra fine
sand grains normally found in new filter sand.
1. Loosen the pump strainer pot lid to allow air to
escape. Tighten lid when water begins to flow
between strainer pot lid and strainer body. Do not
over tighten.
2. Plug in your pump to the GFCI protected receptacle.
Refer to WARNINGS.
3. Install a 1-1/2" waste line (Not supplied-See Waste
Line Hook-up). Be sure to route the hose to a safe
area.
4. Push down on the valve handle and rotate to the
BACKWASH position. Make sure valve handle
indexes into the tabs on cover.
5. Start pump. During this initial start-up, allow 4 to 5
minutes to flush out the super-fine sand grains to
prevent them from plugging the underdrain slots.
Because pool water is lost during this operation
(150 to 200 gallons), keep a close check on pool
water level. Never let water level get so low that no
water flows to pump. Replenish as required.
6. Stop pump. Push down on the valve handle and
rotate to the FILTER TO WASTE position. Start
pump and allow to run approximately 10 seconds to
eliminate any "cloudy puff" out the return fitting inlet,
then stop pump.
7. Push down on the valve handle and rotate to the
filter position and start pump. Note the pressure
reading on your pressure gauge for future reference
of when to backwash.
8. Check tank cover, all fittings and hoses for leaks
and tighten to correct as necessary.

REPAIRS
Servicing should be performed by a qualified dealer. If
disassembly is attempted, mark each of the parts
assembled position as it relates to its mating parts. This
assures proper alignment when reassembled. Malfunc-
tion will occur if not properly assembled. See your
dealer for original replacement parts.
CAUTION
Always unplug your pump from the electrical recep-
tacle BEFORE removing filter or pump from pool for
servicing, and prevent the backflow of water from your
skimmer and return inlet from flowing out of discon-
nected hoses.
1. Remove skimmer cover and basket and plug inside
bottom hole with rag.
2. Referring to the instructions for your return inlet,
remove the inlet cover and eye ball. Insert the
winterizing disc and reinstall the cover.
3. Disconnect hoses on filter or pump as necessary
when removing for service or repairs.
DRAIN TANK
See Caution Above
1. Remove tank clamp from filter. Remove cover and
o-ring.
2. Remove tank drain cap to drain.
3. Place plastic bag over riser tube in tank and secure
with a rubber band. Scoop out sand with a medium
size can and place in plastic bag.
4. After servicing, reassemble and install in reverse.
Make sure tank o-ring and sealing areas are free of
any sand and re-lubricated with silicone lubricant,
and is properly seated in the cover groove.
WINTERIZING FILTER
In areas subject to freezing damage, it is mandatory that
the filter, pump and any related components be re-
moved from the pool and stored indoors. (Refer to
individual components owners guide such as pump,
skimmer, chlorinator, etc., for specific winterizing
instructions.)
1. Backwash the filter.
2. Siphon pool water level down below skimmer
opening by using your vacuum hose and allow
water to flow to an area that can accept a couple of
thousand gallons or more.
3. Remove tank clamp from filter and remove cover
and o-ring.
4. Remove tank drain cap and allow tank to drain fully.
5. Disconnect all hoses.
6. Place plastic bag over riser tube in tank and secure
with a rubber band. Scoop sand out with a medium
size can and place in plastic bag. If sand is not
badly contaminated, save for next season.
7. Store all components in a warm dry area indoors.
DAMAGE CAUSED BY FREEZING TEMPERATURES
IS NOT COVERED BY PRODUCT WARRANTY.
FILTER OPERATION
A newly filled pool is normally filled with unfiltered water
and usually requires continuous filtering for 24 to 48
hours along with chemical treatment of the pool water.
Because all pool installations vary in environmental
conditions (wind, rain, airborne debris, heat and pool
use, etc.), it is impossible to provide an accurate filtering
time for normal usage. Use a trial and error method to
determine how long your filter must operate each day.
Generally, 6 to 8 hours of filtering each day is sufficient
to maintain pool clarity if the pool chemical treatment is
correct. As the water clears, less backwashing will be
required. Consult your local pool store for helpful advice
in keeping your pool clean and sanitary.
When possible, avoid operating your filter during peak
electricity demands in your community. Check with your
local electric utility company for the best times they
recommend for operating your filter pump.
WHEN TO BACKWASH
As your filter removes debris from the pool water during
the filtering process, the return flow will gradually
decrease. Backwash when the pressure gauge
increases 5 to 7 pounds above the clean filter starting
pressure. Normal backwash duration is 1-1/2 to 2
minutes or until water runs clear.
VACUUMING YOUR POOL
When vacuuming your pool, depris is caught in the filter
at a very rapid rate. Consequently, the filter must work
harder, causing a rapid increase in filter pressure, as will
be indicated on the pressure gauge. Frequent back-
washing could be necessary during this process de-
pending on the amount of dirt being vacuumed off the
pool floor. Keep a check on the pool water level and
refill as required.
MAINTENANCE
Preventative maintenance will provide continued,
smooth performance and extend the life of your filter for
many years. Neglect will cause parts to wear or bind,
leaks to occur and could result in costly repairs. Keep
moving parts lubricated and maintain a clean environ-
ment around your filter and related components.
LUBRICATION
There are various types of lubricants available. How-
ever, most are intended for moving metal parts. Unfor-
tunately, these lubricants will harm or degrade the
plastics. DO NOT use petroleum base lubricants. Many
people consider “PETROLEUM JELLY” safe for babies
and can be applied to anything. But, it will DESTROY
most plastics and o-ring seals. Silicone lubricants,
available at your pool dealer, are safe for use on plastics
and o-rings.
LUBE VALVE SHAFT
To lubricate the O-Ring on the valve shaft, depress
valve handle fully and apply lubricant on the shaft
between handle and valve cover. Then, rotate handle to
distribute lubricant. Resume normal filter operation by
rotating handle to the Filter position and start pump.
