I. UNPACKING

1. The LMI Model 28850 Fluoride Saturator is shipped intwo cartons; one containing the 50 gallon polyethylenetank and the other containing the cover assembly,distributor tube assembly, polyethylene inlet tubing,distributor anti-rise pipe and 1/4" NPT male connector.

II. INSTALLATIONl. Install suction tube strainer (Key No.34 on Parts List) by

removing metal conduit nut from threaded connector. Insertthreaded connector up through saturator cover and handtighten conduit nut to hold strainer firmly to cover.

2. Reassembleliquidlevelswitchby sliding largewhitecoupling nut up to saturator cover. While pushing the liquidlevel switch firmly up towards the cover hand tighten thenut onto the threaded connector.

3. Cut clear,flexiblevinyltubingto 34" lengthandaddatubing insert (Key No. 32 on Parts List) to each end. Slipfreeendof tubingintoconnectorat outletof syphonbreakerandtightencompressionnutuntil tubingis heldsecurely. Slide PVC anti-rise pipe over tubing. Connectother end of tubing to distributor tube assembly in samemanner. Distributor tube assembly should rest just atbottom of tank. (See Fig. 2)

NOTE: Tank bottom requires full, flat support - nooverhang

4. Mount Cover Assembly on tank.5. Position Saturator so as to facilitate plumbing of fresh

water inlet line and overflow connections. All plumbingto and away from Saturator is customer supplied. (SeeTypical Installation, pg. 4)

NOTE: All user supplied plumbing must beapproved under local plumbing codes

6. Connect 1/4" NPT male x 3/8" OD tubing connector toinlet water supply piping; it is recommended that a shutoff valve be installed before the connection to allow foreasy replacement of tubing a servicing of Saturator. It isalso recommended that a user supplied Y strainer be installed on inlet line. Route stiff, white tubing fromconnector to inlet of Saturator Cover Assembly.

7. Slip ends of tubing through connectors at both ends andtighten compression nuts until tubing is held securely.

NOTE: Inlet water pressure must not exceed 120PSI (8.6 BAR)

8. An overflow connection have been installed on the tank (3/4"NPT female). Plumbing from this connection should now becompleted.

9. The LMI chemical metering pump is mounted in the recessprovided on the cover assembly.

10. The pump suction tubing should be cut so as to allow thefoot valve assembly to sit at the bottom of the suction tubestrainer after connection to the pump suction valve assem-bly. To accomplish this, connect the suction tubing to thefoot valve assembly and drop into the suction tube straineruntil it rests at the bottom, then cut the tubing at theappropriate height to allow connection to the suction valvefitting. Adjust and operate the pump as required.

III. OPERATIONI Open hinged cover and add 100 lbs. (45kg) of Sodium

Fluoride to the tank. Evenly distribute powder/crystals andmark outside wall of the tank at the level of the SodiumFluoride bed. (See Fig.2)

2. Deposit an additional 100 lbs. of Sodium Fluoride, for atotal of 200 lbs. start up quantity. Close hatch cover.

3. Open water supply to Saturator.

NOTE: If water hardness causes scale build up, auser supplied water softener should be installed inthe supply line ahead of the Saturator.

4. Connect the Saturator power supply cord to a grounded115VACelectrical source capable of supplying 25 watts.This Saturator is equipped with a built in time delay relay.Opening of solenoid valve and water flow into tank will bedelayed 5 to 6 minutes after connection to the power source.When fill cycle begins water will flow into tank, throughdistributor tube assembly, dissolving the Sodium Fluoride.At the proper level the liquid level switch will automaticallyclose the solenoid valve. In this way the proper solutionlevel is maintained in the Saturator tank as saturated

solution is pumped out.5. The level of the Sodium Fluoride bed in the saturator tank

should be checked daily. Push and hold the button switch onthe cover to activate the light inside the tank for visualinspection of Fluoride level. When the level drops to aminimum 100 lb.mark an additional 100 lbs. should beadded.

6. The float switch should be checked periodically and hosedwith clear water if there are any signs of crystallinedeposits.

NOTE: It will always take a minimum of 5 to 6minutes before solenoid valve re-opens after floattriggers time delay relay. This is to prevent rapid fillcycles as a result of waves on the fluoride solutionsurface. Time delay also occurs each time the unitis unplugged and reconnected to power. Light andswitch are 12 volts AC.

2. Allow the Sodium Fluoride bed level to drop to apoint at which the distributor tubes becomevisible. Valve off inlet water.(See Fig.3)

3. Disconnect the power supply to the Saturator and tothe chemical pump and remove the pump from thecover.

4. Disconnect tubing from underside of CoverAssembly. Remove cover being careful not to hitfloat switch assembly against side of tank. Attemptto raise and remove the distributor tube assembly.DO NOT FORCE Stirring may be necessary todislodge distributor tube assembly if embedded.Use caution to avoid damage too assembly.Replace No. 10469 vinyl tubing if necessary.

5. Flush interior of tank with water to removedeposits. Clean and flush distributor tube assemblyand suction tube strainer.

6. Re-install tube assembly, remount pump and referto Section III for start-up instructions.

IV. CLEANINGI. It is recommended that the Fluoride Saturator be

cleaned approximately every twelve months or morefrequently if necessary.
