NEPTUNE SF500 Sand Filters Instruction

Sand Filters

Models: SF500, SF650, SF700 & SF800

Function

The sand filter is designed to remove dirt particles from pool water. The filter media is loaded into the filter tank and functions as a permanent dirt- removing media. When the multiport valve is in the FILTER position, pool water containing suspended dirt particles is pumped through the system and directed by the patented filter multiport valve to the top of the filter tank. As pool water passes through the filter, dirt particles are trapped by the media bed and filtered out. The cleaned pool water is returned from the bottom of the filter tank, passing through the multiport valve and back to the pool via the piping system. This entire sequence is continuous and automatic, providing for total recirculation of pool water through your filter and piping system.

After a period of time, the accumulated dirt in the filter causes a resistance to flow, and the flow diminishes. This means it is time to clean your filter.

With the multiport valve in the BACKWASH position, water flow is automatically reversed through the filter so that it is directed to the bottom of the tank, up through the media, flushing previously trapped dirt and debris out of the waste line. Once the filter is backwashed of dirt, set the multiport valve to the RINSE position and run the pump for about 15 to 30 seconds. Then set the multiport valve in the FILTER position to resume normal filtering.

Note: Turn off the pump before changing the multiport valve position.

Installation

Only simple tools plus pipe sealant for plastic adapters are required to install and service the filter.

1. The filter should be placed on a level concrete slab, very firm ground, or equivalent. The filter should be placed in the right position so that the piping connections and multiport valve are convenient and accessible for operation and service. Position the tank with MPV in place to determine the final position for piping.
2. Filter media is loaded through the top opening of the filter.
3. (For 500/650) Loosen the flange clamp and remove filter multiport valve (if previously installed).
4. (For 700/800) Loosen the flange Nuts and remove filter multiport valve (if previously installed).
5. Cap internal pipe with plastic cap to prevent filter media from entering it.
6. We recommend filling the tank approximately halfway with water to provide a cushion effect when the filter media is poured in. This helps protect the under-drain laterals from excessive shock.
7. Carefully pour in the correct amount and grade of filter media. (Be sure the center pipe remains centered in the opening.) Media surface should be leveled and should come to about the middle of the filter tank. Remove plastic cap from internal pipe.
8. Assemble the filter multiport valve onto the filter tank.
9. Insert multiport valve (with O’ring or casket in place) onto the tank neck, taking care that the center pipe slips into the hole in the bottom of the valve.
10. (For 500/650) Place clamp around valve flange and tank flange and tighten just enough so that the valve may be rotated on the tank for final positioning.
11. (For 700/800) Place nuts on all studs around valve flange and tighten just enough so that the valve casket seals (Do not over tighten).
12. Carefully screw the pressure gauge (with tread tape) into the tapped hole in the valve body. Do not over-tighten.
13. Connect the pump to the multiport valve opening marked PUMP. After connections are made, recheck to ensure nuts or clamp band on multiport valve flange are tight.
14. Make the return to pool pipe connection to multiport valve opening marked RETURN and complete other necessary plumbing connections, suction lines to pump, waste, etc.
15. Make electrical connections to pump per pump instructions.
16. To prevent water leakage, make sure all pipe connections are tight.

Following these instructions will ensure proper usage and maintenance of your sand filter. If you have any questions or concerns, please consult the user manual provided or contact customer support.

INSTALL/START-UP OF FILTER

1. Make sure the correct amount of filter media is located in the tank and all connections have been connected and secured.
2. Depress multiport valve handle and rotate to BACKWASH position. (To prevent damage to multiport valve seal, always depress handle before turning.)
3. Prime and start pump according to pump instructions (be sure all suction and return lines are open), allowing the filter tank to fill with water. Once water is flowing out of the waste line, run the pump for at least 1 minute. The initial back-washing of the filter is recommended to remove any impurities or fine particles in the filter media
4. Turn pump off and set valve to RINSE position. Start pump and operate until water in sight glass is clear, about 30 seconds. Turn pump off and set valve to FILTER position and restart pump. The filter is now operating in the normal filter mode, filtering dirt particles from the pool water.
5. Adjust pool suction and return valves to achieve desired flow. Check system and filter for water leaks and tighten connections, bolts, nuts, as required.
6. Note the initial pressure gauge reading when the filter is clean. (It will vary from pool to pool depending upon the pump and general piping system.) As the filter removes dirt and impurities from the pool water, the accumulation of dirt in the filter will cause the pressure to rise and diminish the water flow. When the pressure gauge reading is 50kpa, higher than the initial “clean” pressure you noted, it is time to backwash the filter (see BACKWASH under filter and multiport valve functions).
   NOTE: During initial clean-up of the pool water it may be necessary to backwash frequently due to the unusually heavy initial dirt load in the water.
