Frequently Asked Questions - SandMaster SM2306T HAYWARD

How to install the SandMaster SM2306T sand filter?

Place the filter on a level and firm concrete slab. Assemble the pump to the base. Use sealant for plastic fittings. Connect the pipes according to the markings (PUMP, RETURN, WASTE). Fill the tank with silica sand (250 lb) through the top opening after covering the internal pipe. Mount the control valve and tighten the clamp.

How much sand is needed for the SM2306T?

Exactly 250 lb (114 kg) of #20 or #1/2 silica sand (0.45-0.55 mm) is required. Use special pool filter sand.

How to perform backwashing?

Stop the pump. Press down on the Vari-Flo valve handle and turn it to BACKWASH position. Restart the pump and run until water is clear in the sight glass (about 2 minutes). Stop, switch to RINSE for 30-60 seconds, then return to FILTER.

When should you backwash the filter?

Backwash when the pressure gauge reading increases by 8 to 10 psi (0.55 to 0.69 bar) over the clean initial pressure. This indicates the sand is clogged.

What to do in case of low water flow?

Check that the pump strainer and intake grates are not clogged. Ensure that the inlet and outlet lines are not obstructed. Look for air leaks in the inlet line (bubbles). If necessary, backwash the filter.

How to winterize the filter?

Drain the tank completely by unscrewing the drain plug at the bottom. Remove the plug for the entire winter. Set the valve to neutral position (between settings) to allow drainage. Store the pump and motor in a dry, warm place.

What are the Vari-Flo valve settings?

The 6 positions are: FILTER (normal filtration), BACKWASH (sand cleaning), RINSE (rinsing after backwash), WASTE (drain or direct suction), RECIRCULATE (water bypassing the filter), CLOSED (shut off flow).

How to maintain chemical balance of the water?

Maintain pH between 7.2 and 7.6, chlorine between 1 and 3 ppm (stabilized), and alkalinity between 100 and 130 ppm. Adjust with appropriate chemicals (soda ash for pH, muriatic acid to lower pH, etc.).

Why does pool water remain cloudy despite filtration?

Check chlorine, pH, and total alkalinity levels. Ensure the filtration flow rate is sufficient. Increase filter run time. If necessary, perform a shock treatment with chlorine. Also verify that the valve is set to FILTER mode.

Where to find replacement parts for the SM2306T?

Replacement parts are available at authorized Hayward dealers or on the official website. The main parts are: valve assembly (SP-0714TC), pressure gauge (EC-2708-1), O-ring (GM-600-F), clamp (GM-600-NM), lateral mounting (S-220-DA), tank (S-220-AB), lateral tubes (S-200-Q), drain plug (S-180-LM), stand (S-200-J).

USER MANUAL SandMaster SM2306T HAYWARD

Your Sandmaster high rate sand filter is a high performance totally corrosion-proof filter that blends superior flow characteristics and features with ease of operation. It represents the very latest in high rate sand filter technology. It is virtually foolproof in design and operation and when installed, operated and maintained according to instructions, your filter will produce clear, sparkling water with only the least attention and care.

HOW IT WORKS

The Sandmaster uses special filter sand to remove dirt particles from pool water. Sand is loaded into the filter tank and functions as the permanent dirt removing media. The pool water, which contains suspended dirt particles, is pumped through your piping system and is automatically directed by the patented filter control valve to the top of the filter tank. As the pool water is pumped through the filter sand, dirt particles are trapped by the sand bed, and filtered out. The cleaned pool water is returned from the bottom of the filter tank, through the control valve and back to the pool through the piping system. This entire sequence is continuous and automatic and provides 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 (backwash) your filter. With the control valve in the backwash position, the water flow is automatically reversed through the filter so that it is directed to the bottom of the tank, up through the sand, flushing the previously trapped dirt and debris out of the waste line. Once the filter is backwashed (cleaned) of dirt, the control valve is manually resequenced to Rinse, and then Filter, to resume normal filtering.

INSTALLATION

Only simple tools (screwdriver and wrenches), plus pipe sealant for plastic adapters, are required to install and/or service the filter.

1. The filter system should be placed on level, very firm ground, or equivalent, as recommended by your pool dealer. Position the filter so that the piping connections, control valve and winter drain are convenient and accessible for operation, servicing and winterizing.

2. Assemble the Pump to the platform base. The flexible hose and adapters must now be installed to connect the pump/filter system.

a. Screw straight adapter, using Teflon pipe sealant tape or Permatex No. 2, securely into 112 pump discharge.
b. Screw other straight adapter, using Teflon pipe sealant tape or Permatex No. 2, securely into opening in control valve marked PUMP. (Do not overtighten.)

STOP here and load media per instructions (No. 3).

c. Place hose clamps on hose and fit hose over straight adapters and secure with clamps. If hose is difficult to fit over adapters, place hose in hot water for several minutes.

NOTE: To prevent breakage and damage to pump and control valve, use only pipe sealants specifically formulated for plastics. Do not overtighten fittings or adapters.

Figure A

1. Loading sand media. Filter sand media is loaded through the top opening of the filter.

a. Loosen flange clamp and remove Filter Control Valve (if previously installed).
b. Cap internal pipe with plastic cap to prevent sand from entering it. Be sure pipe is securely in place in bottom underdrain hub.
c. We recommend filling tank approximately 1/2 way with water to provide a cushioning effect when the filter sand is poured in. This helps protect the under-drain laterals from excessive shock. (Be sure the winter drain cap is securely in place on drain pipe.) Note: Please check to confirm all laterals are in the down position before loading with sand. See figure A.
d. Slowly pour in correct amount and grade of filter sand, as specified. (Be sure center pipe remains centered in opening.) Sand surface should be leveled and should come to about the middle of the filter tank. Remove plastic cap from internal pipe.

1. Assemble Filter Control Valve to filter tank.

a. Place stainless steel valve flange clamp around neck of tank. Do not tighten. Wipe filter flange clean.
b. Insert Filter Control Valve (with valve/flange o-ring in place) into the tank neck, taking care that the center pipe slips into the hole in the bottom of the valve. Place clamp around valve flange and tank flange and tighten just enough so that the valve may be rotated on tank for final positioning.
c. Carefully screw pressure gauge, with pipe tape, into 1/4 tapped hole in valve body. Do not overtighten.
d. Connect pump to control valve opening marked PUMP according to instructions. After connections are made, tighten valve flange clamp with screwdriver, tapping around clamp with screwdriver handle to help seat valve flange clamp.

1. Make return to pool pipe connection to control valve opening marked RETURN and complete other necessary plumbing connections, suction lines to pump, waste, etc.
2. Make electrical connections to pump per pump instructions.
3. To prevent water leakage, be sure winter drain cap is securely in place and all pipe connections are tight.

INITIAL START UP OF FILTER

1. Be sure correct amount of filter sand media is in tank and that all connections have been made and are secure.
2. Depress Vari-Flo control valve handle and rotate to BACKWASH position. (To prevent damage to control 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 flow is steady out the waste line, run the pump for at least 2 minutes. The initial backwashing of the filter is recommended to remove any impurities or fine sand particles in the sand media.

4. Turn pump off and set valve to RINSE position. Start pump and operate until water in sight glass is clear - about 1/2 to 1 minute. Turn pump off and set valve to FILTER position and restart pump. Your filter is now operating in the normal filter mode, filtering 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 in the filter will cause the pressure to rise and flow to diminish. When the pressure gauge reading is 8-10 lbs. (4-6 BAR) higher than the initial "clean" pressure you noted, it is time to backwash (clean) the filter (see BACKWASH under Filter and Control 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.

CAUTION: To prevent unnecessary strain on piping system and valving, always shut off pump before switching Filter Control Valve Functions positions.

To prevent damage to the pump and filter and for proper operation of the system, clean pump strainer and skimmer baskets regularly.

FILTER AND CONTROL VALVE FUNCTIONS

FILTER - Set valve to FILTER for normal filtering. Also use regular vacuuming.

BACKWASH - For cleaning filter. When filter pressure gauge rises 8-10 lbs. (4-6 BAR) above start-up (clean pressure): Stop the pump, set valve to BACKWASH. Start pump and backwash until waste water is clear. Approximately 2 minutes or less depending on dirt accumulation. Proceed to RINSE.

RINSE - After backwashing, with pump off, set valve to RINSE. Start pump and operated for about 1/2 to 1 minute. This assures that all dirty water from backwashing is rinsed out of the filter to waste, preventing possible return to the pool. Stop pump, set valve to FILTER, and start pump for normal filtering.

WASTE - To bypass filter for draining or lowering water level and for vacuuming heavy debris directly to waste.

RECIRCULATE - Water is recirculated through the pool system by-passing the filter.

CLOSED -Shuts off flow from pump to filter.

VACUUMING - Vacuuming can be performed directly into the filter. When vacuuming heavy debris loads, set valve to WASTE position to bypass the filter and vacuum directly out to waste.

*NOTE: For new concrete or gunite pools, or where there is a large amount of plaster dust or debris - start filter in FILTER position (not BACKWASH) to prevent clogging of underdrain laterals.

WINTERIZING

1. Completely drain tank by unscrewing drain cap at base of filter. Leave drain cap off for the duration of the winter months.

2. Depress Vari-Flo control valve handle and rotate so as to set valve pointer on valve top between any position. This will allow water to drain from the valve. Leave valve in this "inactive" position.

3. ALL MOTORS AND PUMPS - Off season, motor should be stored indoors in a warm, dry place. Motors left outdoors should not be tightly wrapped with plastic, as moisture will be trapped, resulting in condensation and damage to the motor.

SERVICE & REPAIRS

Consult your local authorized Hayward dealer or service center. No returns may be made directly to the factory without the express written authorization of Hayward Pool Products, Canada, Inc.

PLEASE REALIZE...

Pure, clear swimming pool water is a combination of two factors - adequate filtration and proper water chemistry balance. One without the other will not give the clean water you desire. Your filter system is designed for continuous operation. However, this is not necessary for most swimming pools. You can determine your filter operation schedule based on your pool size and usage. Be sure

to operate your filtration system long enough each day to obtain at least one complete turnover of your pool water. To properly sanitize your pool, maintain a free chlorine level of 1 to 2ppm and a pH range of 7.2 to 7.6. Insufficient chlorine or an out of balance pH level will permit algae and bacteria to grow in your pool and make it difficult for your filter to properly clean the pool water.

PROBLEM SOLVING LIST
