INSTALLATION INSTRUCTION

Congratulations! You have purchased one of the most user-friendly pool filter systems available. Ideal for an above-ground pool or inground vinyl liner pool, it will provide you with many years of pool enjoyment. This step-by-step installation and maintenance guide will provide the necessary information for you to install your new pool system and easily maintain the equipment. Before installation be sure to read all instructions and warnings carefully. Refer to product dataplate(s) for additional operation instruction and specifications.

• Warning: This filter operates under pressure. If this unit is not assembled properly or is operated with air in the circulation system, serious bodily injury and/or property damage could occur.
• Warning: Your filter is a pressure vessel and should never be serviced while under pressure. Always shut off pump to relieve the pressure in the filter prior to servicing the unit.
• Warning: To reduce risk of injury, do not permit children to use this product unless they are closely supervised at all times.
• Warning: Locate the system at least five feet (1.5M) from the pool to prevent it being used as a means of access to the pool by young children. (See ANSI/NSPI-8 1996 “Model Barrier Code For Residential Swimming Pools, Spas and Hot Tubs”).

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, but keep at a distance of at least five feet (1.5 M). (See previous warning). Give consideration to draining – 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
A 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:

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-On 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.

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. SAND FILTER PREPARATION DO NOT PLACE SAND IN THE FILTER TANK BEFORE IT IS POSITIONED AS ITS WEIGHT WILL MAKE MOVING THE TANK MORE DIFFICULT AND MAY CAUSE DAMAGE.)
Remove bag of miscellaneous parts and proceed as follows:

1.  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 located in Misc. parts bag.
2.  Fill tank approximately 1/2 full of water.
3.  Add sand (not provided) following recommendation for size and amount. Be sure that the standpipe remains centered while pouring sand. Be sure sand is level.
4.  Remove cover from a standpipe.

DIAL VALVE INSTALLATION

Carefully remove all sand particles from the mounting location. Position the rubber O-ring on the dial valve body. Place valve on tank and rotate until the valve inlet is approximately in line with the pump outlet opening. Install the V-clamp. Install pressure gauge after wrapping threads with teflon tape.
DIAL VALVE FUNCTIONS

FILTER – For normal filtering. This position also can be used for regular vacuuming.
BACKWASHING – 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 filter and go directly to the 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 sitting 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 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 wastewater. When flow becomes clear (approximately 2 to 3 minutes). STOP pump.
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 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 pools 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 the 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 the proper application and use of chemicals.

FILTER MAINTENANCE
Filter tank and contents should not require attention other then backwashing provided water is kept in continuous chemical balance without heavy dosages of corrosive chemicals.

CLEANING FILTER (Backwashing)
When the new filter is placed in service, note the reading on pressure gauge. As dirt builds up in filter, the pressure reading will increase. When it reads 6-8 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.
3.  Observe the waste water. STOP pump when flow becomes clear (approximately two 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 wintering 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.
