USER MANUAL SandMaster SM2506T HAYWARD

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

The Sandmaster uses special lter sand to remove dirt particles from pool water. Sand is loaded into the lter 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 lter control valve to the top of the lter tank. As the pool water is pumped through the lter sand, dirt particles are trapped by the sand bed, and ltered out. The cleaned pool water is returned from the bottom of the lter 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 lter and piping system. After a period of time the accumulated dirt in the lter causes a resistance to ow, and the ow diminishes. This means it is time to clean (backwash) your lter. With the control valve in the backwash position, the water ow is automatically reversed through the lter so that it is directed to the bottom of the tank, up through the sand, ushing the previously trapped dirt and debris out of the waste line. Once the lter is backwashed (cleaned) of dirt, the control valve is manually resequenced to Rinse, and then Filter, to resume normal ltering. INSTALLATION Only simple tools (screwdriver and wrenches), plus pipe sealant for plastic adapters, are required to install and/or service the lter. The lter system should be placed on level, very rm ground, or equivalent, as recommended by your pool dealer. Position the lter so that the piping connections, control valve and winter drain are convenient and accessible for operation, servicing and winterizing. Assemble the Pump to the platform base. The exible hose and adapters must now be installed to connect the pump/lter system.

6a 6b 6c 6d 6e Figure A www.haywardpool.caLoosen ange clamp and remove Filter Control Valve (if previously installed). Cap internal pipe with plastic cap to prevent sand from entering it. Be sure pipe is securely in place in bottom underdrain hub. We recommend lling tank approximately 1/2 way with water to provide a cushioning eect when the lter 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 conrm all laterals are in the down position before loading with sand. See gure A. Slowly pour in correct amount and grade of lter sand, as specied. (Be sure center pipe remains centered in opening.) Sand surface should be leveled and should come to about the middle of the lter tank. Remove plastic cap from internal pipe.

Loading sand media. Filter sand media is loaded through the top opening of the lter. Assemble Filter Control Valve to lter tank. Place stainless steel valve ange clamp around neck of tank. Do not tighten. Wipe lter ange clean. Insert Filter Control Valve (with valve/ange 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 ange and tank ange and tighten just enough so that the valve may be rotated on tank for nal positioning. Carefully screw pressure gauge, with pipe tape, into 1/4 tapped hole in valve body. Do not overtighten. Connect pump to control valve opening marked PUMP according to instructions. After connections are made, tighten valve ange clamp with screwdriver, tapping around clamp with screwdriver handle to help seat valve ange clamp. Make return to pool pipe connection to control valve opening marked RETURN and complete other necessary plumbing connections, suction lines to pump, waste, etc. Make electrical connections to pump per pump instructions. To prevent water leakage, be sure winter drain cap is securely in place and all pipe connections are tight.

INITIAL START UP OF FILTER

Be sure correct amount of lter sand media is in tank and that all connections have been made and are secure. Depress Vari-Flo control valve handle and rotate to BACKWASH position. (To prevent damage to control valve seal, always depress handle before turning.) Prime and start pump according to pump instructions (be sure all suction and return lines are open), allowing the lter tank to ll with water. Once water ow is steady out the waste line, run the pump for at least 2 minutes. The initial backwashing of the lter is recommended to remove any impurities or ne sand particles in the sand media.

Turn pump o 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 o and set valve to FILTER position and restart pump. Your lter is now operating in the normal lter mode, ltering particles from the pool water. Adjust pool suction and return valves to achieve desired ow. Check system and lter for water leaks and tighten connections, bolts, nuts, as required. Note the initial pressure gauge reading when the lter is clean. (It will vary from pool to pool depending upon the pump and general piping system.) As the lter removes dirt and impurities from the pool water, the accumulation in the lter will cause the pressure to rise and ow to diminish. When the pressure gauge reading is 8-10 Ibs. (4-6 BAR) higher than the initial "clean" pressure you noted, it is time to backwash (clean) the lter (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 o pump before switching Filter Control Valve Functions positions. To prevent damage to the pump and lter 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 ltering. Also use regular vacuuming. BACKWASH - For cleaning lter. When lter pressure gauge rises 8-10 Ibs. (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 o, 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 lter to waste, preventing possible return to the pool. Stop pump, set valve to FILTER, and start pump for normal ltering. WASTE - To bypass lter 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 lter. CLOSED - Shuts o ow from pump to lter. VACUUMING - Vacuuming can be performed directly into the lter. When vacuuming heavy debris loads, set valve to WASTE position to bypass the lter 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 lter in FILTER position (not BACKWASH) to prevent clogging of underdrain laterals. www.haywardpool.caCompletely drain tank by unscrewing drain cap at base of lter. Leave drain cap o for the duration of the winter months. 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. WINTERIZING PLEASE REALIZE... Pure, clear swimming pool water is a combination of two factors - adequate ltration and proper water chemistry balance. One without the other will not give the clean water you desire. Your lter system is designed for continuous operation. However, this is not necessary for most swim- ming pools. You can determine your lter operation sched- ule based on your pool size and usage. Be sure

ALL MOTORS AND PUMPS - O 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. to operate your ltration 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 2 ppm and a pH range of 7.2 to 7.6. Insucient chlorine or an out of balance pH level will permit algae and bacteria to grow in your pool and make it dicult for your lter to properly clean the pool water.

Check skimmer and pump strainer baskets for debris. Check for restrictions in intake and discharge lines. Check for air leak in intake line (indicated by bubbles returning to pool). Backwash lter.

Check for algae in pool and superchlorinate as required. Be sure chlorine and pH levels are in proper range (adjust as required). Check surface of lter sand for crusting or caking (remove 1” of sand if necessary).

POOL WATER WON’T CLEAR UP

Check chlorine, pH and total alkalinity levels and adjust as required. Be sure ow rate through lter is sucient. Operate lter for longer periods. Be sure control valve is set on “Filter” position.
