THIS FILTER OPERATES UNDER HIGH PRESSURE, WHEN ANY PART OF THE CIRCULATING SYSTEM, i.e., FILTER, PUMP, VALVE(S), CLAMPS, ETC. IS SERVICED, AIR CAN ENTER THE SYSTEM AND BECOME PRESSURIZED WHEN THE SYSTEM IS STARTED. TO AVOID THIS POTENTIAL HAZARD, FOLLOW THE INSTRUCTIONS IN THIS MANUAL.

ATTENTION INSTALLER:

This manual contains important information about the installation, operation and safe use of this product. This information should be given to the owner/operator of this equipment.

SECTION 2. General Information

2A. Introduction

This manual contains information for the proper installation and operation of Jandy TM Sand Filters. Procedures in this manual must be followed exactly. To obtain additional copies of this manual contact us at 415-382-8220, ext. 237.

2B. Description

Debris is collected in the filter as the water flows through the multiport valve (MPV), plumbed to the filter, and directed into the top bulkhead. Dirty water flows into the diffuser at the top of the tank and is directed downward onto the top of the filter sand bed. The debris is collected in the sand bed and the clean water flows through the laterals and lower piping at the bottom of the filter up into the lower bulkhead. Clean water then goes into the MPV and is returned through the piping system to the pool. As debris collects in the filter, the pressure will rise and water flow to the pool will diminish. The filter will eventually become so plugged with debris that it will be necessary to perform the backwash procedure. It is important to know when to backwash the filter. See Section 4 for further discussion of backwashing the filter.

Note: A filter removes dirt and other suspended particles, and does not sanitize the pool. Pool water must be sanitized and chemically balanced for clear water. The filtration system should be designed to meet local health codes. As a minimum, the system should turnover the total volume of water in your pool at least two to four times in a 24 hour period.

2C. General Requirements

1. For best overall performance locate the system as close as possible to the pool. 2. The filter should be located on a level concrete slab so that the orientation of the valve outlets are convenient and accessible for the installation and operation of the unit. 3. Provide for protection from the weather. 4. If fitting a chlorinator and/or any other device into the filtration plumbing circuit, great care must be exercised to ensure that the appliance is installed in accordance with the Manufacturer’s Instructions and any Standards that may exist. Incorrect application may void product warranty. 5. Provide barrel unions to each item of equipment for future servicing of equipment. All Teledyne Laars/Jandy Products filters come with these type of fittings. 6. The maximum working pressure for SF-T & SF-S filters is 50 psi (for ST-T filters the maximum working pressure is 35 psi). Never subject the filter to pressure exceeding recommended psi, even when conducting hydrostatic pressure tests.

When performing hydrostatic pressure tests, or when testing for external leaks of the completed filtration and plumbing system, ensure that the maximum pressure the filtration system is subjected to does not exceed the maximum working pressure of any of the components within the system.

2D. Sand Requirements

1. Use a #20 Silica Sand (for pool filter use only), with a size range of .40-.55mm. 2. See Table 1 for recommended quantity of sand required. 3. Recommended sands: a. Wedron Silica/Best Sand Co. Sand Grade- .45-.55mm Effective Size- .46mm b. U.S. Silica/Silurian Filter Sand Sand Grade- .45-.55mm Effective Size- .48mm

SECTION 3. Installation Instructions

3A. Filter Preparation

1. Check carton for any damage due to rough handling in shipment. If carton or any filter components are damaged, notify carrier immediately. 2. Carefully remove the accessory package and the filter tank from the carton. 3. A visual inspection of all parts should be made now. 4. Mount the pressure gauge to the top of the filter.

Note: On top mount filters, the pressure gauge mounts into the MPV. 5. Install the pressure release valve to the top of the filter. Note: On top mount filters, the pressure relief knob mounts into the MPV.

3B. Filter Location

1. Select a well-drained area, one that does not flood when it rains. Damp, non-ventilated areas should be avoided. 2. Provide solid mounting for the filter and pump system. Install system on a concrete slab or solid concrete blocks to avoid risk of settlement. Do not use sand to level the filter, as the sand will wash away. Filter systems, once loaded with media, can weigh up to 800 lbs. 3. Install electrical controls at least five (5) feet from the filter. This will allow enough room to stand away from the filter during start-up. 4. Allow sufficient clearance around the filter to permit a visual inspection of the entire system. 5. Position the filter to safely direct water drainage. Align the pressure release valve to safely direct purged air or water. 6. If the system is to be located above water level it can be raised 2.5 ft., without affecting the pump efficiency. A check valve is recommended on the suction line to the pump.

WARNING

Water discharged from an improperly positioned filter or valve can create an electrical hazard and can dam-age property.

SECTION 4. Start-Up and Operation

4A. New Pool and Seasonal Start-Up

1. With the pump off , set MPV to "Backwash" position. Remove the hair/lint pot lid and fill with water. Replace the hair/lint pot lid 2. Open pressure release valve on filter or MPV. 3. Stand clear of the filter, start the pump and circulate the water backwards through the filter to waste. 4. Close pressure release valve when a steady stream of water is moving through the filter. 5. Run the pump for approximately five minutes or until waste water is clear (this purges excess fine particles from the system). 6. Turn the pump off , and move valve handle to the "Rinse" position. Stand clear of the filter, turn pump on and circulate the water for 10 seconds. 7. Turn pump off , move the valve handle to "Filter". Stand clear of the filter, and start the pump. 7. If the system is to be installed below water level, valves should be on both the suction and return lines to prevent back flow of pool water during any routine servicing that may be required.

3C. Filter Installation

1. This filter operates under pressure. When clamped properly and operated without air in the water system, this filter will operate in a safe manner. 2. If doubt exists as to the pressure which the system will be subjected to, install an ASME approved automatic Pressure Relief Valve or Pressure Regulator in the circulation system for the lowest working pressure of any of the components in the system. 3. Place on the concrete pad, lined up with the inlet/outlet pipes. 4. To reduce pressure losses, 2" (minimum) piping is recommended. 5. For best efficiency use the fewest possible fittings. This will prevent a restriction in the water flow. 6. Make all plumbing connections in accordance with local plumbing and building codes. Filter connections are provided with an o-ring seal. Do not use pipe joint compound, glue or solvent on bulkhead connections.

7. Keep piping tight and free of leaks. Pump suction line leaks may cause air to be entrapped in filter tank or loss of prime at the pump. Pump discharge line leaks may show up as dampness or jets of water. 8. Support the inlet/outlet pipes independently to prevent any undue strains on the filter valve. 9. Connect the pipes using the unions supplied with the filter. Do not use teflon tape or pipe dope on any unions. Assemble the unions dry and hand tighten. 10. Be sure that all provisions for waste water disposal meet local, state or national codes. One hundred gallons or more of pool water will be discharged during filter backwashing. Do not discharge water where it will cause flooding or damage.

Caution

The pressure gauge is the primary indicator of how the filter is operating. Maintain your pressure gauge in good working order.

Caution

Do not operate filter at water temperatures above 120° F (65.5° C).

WARNING

Water discharged from an improperly positioned filter or valve can create an electrical hazard which can cause death, serious injury or property damage.

WARNING NEVER operate the filter system at more than 50 pounds per square inch pressure. Operating the filter system in excess of 50 psi can cause the filter lid to be blown off, which can cause death, serious personal injury or property damage.

WARNING NEVER start pump while standing within five (5) feet of the filter. Starting the pump while there is pressur-ized air in the system can cause the filter lid to be blown off, which can cause death, serious personal injury or property damage.

SECTION 5. Backwashing the Filter

5A. Backwashing

1. Turn the pump off. 2. With filter pump off , set the MPV handle to "Backwash" position. 3. Open pressure release valve. 4. Stand clear of the filter, and start the pump to circulate the water backwards through the filter to the waste line. 5. Close pressure release valve until a steady stream of water is moving through the filter. 6. Backwash until water is clear. 7. Turn off the pump and set the MPV handle to the "Rinse" position. 8. Stand clear of the filter, turn on the pump then run the pump for one minute. 9. Turn off the pump and set the MPV handle to the "Filter" position. 10. Follow the steps under 4B "Normal Operation" to restart the system.

Caution

Be sure all provisions for waste water disposal meet applicable local, state or national code. 100 gals. or more of pool water will be discharged during filter backwashing. Do not discharge where water will cause flooding or damage.

WARNING

To avoid equipment damage and personal injury, never change control valve handle while pump is run-ning.

4B. Normal Operation

1. With the pump off , set MPV handle to "Filter" position. 2. Fill the hair/lint pot, on the pump, with water. 3. Open filter pressure release valve, stand clear of the filter, and turn the pump on.

4. When a steady stream of water comes from the pressure release valve, close the valve. 5. With the filter/pump operating, record the initial pressure gauge reading in this manual. When reading is 10 to 12 psi above the initial reading it is time to backwash the filter.

4C. Valve Operation

1. The flow of water through a sand filter is controlled by the multiport valve (MPV) which comes completely assembled and ready for operation. 2. The handle on top of the MPV can be moved to any of six different positions. The function of each position is described below.

Valve Position Function

FILTER Normal filtration and vacuuming. BACKWASH Cleaning filter by reversing the flow. RINSE Used after backwash to flush dirt from the valve. WASTE Bypasses filter; used for vacuuming to waste, or lowering water level. RECIRCULATE Bypasses filter for circulating water to the pool. CLOSED Shuts off all flow to the filter and pool.

SECTION 6. Maintenance

6A. General Maintenance

1. Wash outside of filter with a mild detergent and water. Rinse off with a hose. Do not use solvents to clean the filter, solvents will damage the plastic components of the filter. 2. Inspect the sand bed at least once a year. Remove any foreign material which has not been backwashed out of the system. 3. Check pressure during operation at least once a week. 4. Remove any debris from the skimmer basket. 5. Check pump and filter for any leaks. If any leaks develop, turn off the pump and call a qualified pool service technician.

6B. Pressure Gauge

1. During operation of the filtration system, check the pressure gauge for air or water leaks at least twice a week. 2. Keep the pressure gauge in good working order. If you suspect a problem with the gauge, Teledyne Laars/Jandy Products recommends you call a qualified service technician to do any work on the filter/pump system.

SECTION 7. Winterizing

7A. Winterizing

1. Turn off the pump. 2. Open pressure release valve and move the MPV handle to a position between two ports. This will allow air to flow to all ports. 3. Remove any drain plugs from the filter. 4. Drain system piping of all water. 5. Cover the system with a tarpaulin or plastic sheet to protect from the weather.

5B. Filter Disassembly/Assembly

1. Backwash filter according to the instructions under "Backwashing the Filter" (omit this step when first filling a new filter). 2. Stop the pump, disconnect the power if necessary. 3. Open pressure release valve on top of the filter tank to release all air pressure from inside the tank and system. On models with a top mounted valve, the pressure release valve is on the multiport valve. 4. Remove the filter drain plug from the bottom of the tank and drain any water remaining in the system. 5. Unscrew the multiport valve (on top mounted models) and remove. On side mounted models unscrew the cap on top of the filter tank. 6. Before filling the filter tank with sand, make sure that the correct grade and quantity is used (see Section 2D). 7. Before pouring the sand into the filter tank, do a visual check of the laterals. Look for broken or loose laterals. Replace if necessary. 8. After removing the top cap, on Side Mount Filter models, there will be one or two funnels visible. Cover these funnels to prevent sand from entering the laterals. Also, cover the breather tube assembly. Be sure to uncover them after step 10. 9. To eliminate stress on the laterals, fill tank with enough water to cover the laterals.

10. Wash all sand and debris away from the threads of the filter tank. Remove covers over the funnels. 11. When assembling the top cap or MPV, check the o-ring for cracks or tears. Replace if necessary. 12. Thread the top cap or MPV into the filter tank. Hand tighten only.

Caution

The pressure gauge is the primary indicator of how the filter is operating. Maintain your pressure gauge in good working order.

Troubleshooting Guide

Fault Symptom Possible Problems

Water is not clear. Insufficient disinfectant level. Incorrect pool chemistry. Heavy bathing and/or dirt loads. Incorrect flow. Insufficient running times. (Increase pump run time.) Filter is dirty. (Backwash per instructions.) Low water flow. Check strainer baskets for debris. Check for air leaks on suction side. Check for restrictions or blockage in either suction or return lines. Filter needs to be backwashed. Pool water level too low. Pump not primed. Pump impeller vanes blocked. Strainer baskets not being used and/or not being cleaned regularly.
