1. Connect power to the unit. 2. Set the timer to the correct time of recharge and time of day. 3. Slowly rotate the timer cam gear assembly (C -E, Fig. 25) clockwise until the piston motor is energized. After the piston has moved all the way in to the backwash position, disconnect power to the timer. 4. Slowly open the inlet valve to allow the mineral tank to fill with water from the bottom to the top. 5. When all the air has been expelled from the media tank, check for leaks and correct as needed. NOTICE: When starting -up duplex units with duplex plugs, one unit must be partially filled in the service position in order to fill the other unit in the backwash position. A. Alternate each control between service and back wash at low flow until all air has been expelled from both tanks, or B. Remove the fill port plugs, fill both tanks with the valves in the service position, and replace the plugs. 6. Reconnect power to the timer. Rotate the timer cam gear to the brine/rinse position and wait 10 seconds. 7. Rotate the timer cam gear to the fast rinse/refill posi- tion, wait 60 seconds, and return the gear to the service position. 8. Initiate a manual recharge and allow the recharge cycle to run to completion. Measure the flow to drain during each recharge cycle. A. Backwash - If the water is cold and the water pres- sure is high, the media bed may expand too much during backwash, even if the flow rate is correct. If media is present in the drain (other than a small amount of fine particles), reduce the pressure or in- stall a fine -slotted inlet manifold. NOTICE: A fine - slotted manifold is more likely to become fouled by dirt or iron than the standard wide -sloped manifold. B. Brine Draw/Slow Rinse - Water pressure can also affect the brine/rinse rate. If the flow is too high, capacity will be less than expected. If too low, brine may not be rinsed from the tank. If the pressure can- not be changed, it may be possible to substitute the next larger or smaller eductor nozzle. Start -Up Procedure C. Fast Rinse - The fast rinse flow should be approxi- mately the same as the backwash flow. D. Refill - The refill flow determines the salt dosage, so if the refill flow varies from the standard flow the salt dosage will be too high or too low. Use the following calculations to compensate for a non-standard refill flow: Refill Minutes = Desired Salt Dosage 3 x Refill Flow In metric measure, the formula is: Refill Minutes = Desired Salt Dosage, kg 0.36 x Refill Flow, Umin For example, if the desired salt dosage for a single unit is 20 pounds, and the refill flow is 0.65 gpm, 20 pounds Refill Time = 3 x 0.65 gpm _ 20 1.95 10.3 minutes In this example, the refill setting would be 11 minutes (always round up). NOTICE: Do not forget to increase the refill time for duplex units by 20% if each unit recharges every day. For example, 10.3 minutes x 1.2 = 13 minutes refill time. 9. Open the outlet valve and close the bypass valve. A WARNING! THE UNIT IS NOW AT LINE PRES- SURE. DO NOT DISASSEMBLE ANY PART OF THE CONTROL VALVE OR REMOVE THE CONTROL FROM THE TANK ASSEMBLY OR ASSOCIATED PLUMBING BEFORE CLOSING THE INLET SUPPLY VALVE AND OPENING A FAUCET DOWNSTREAM TO RELIEVE PRESSURE. 10. Test the water downstream for hardness. NOTICE: Because of the volume of water contained in the down- stream plumbing, the water may not be soft immediately, especially in a water heater or similar storage tank. Soft water can be made available immediately by draining the plumbing and storage tank(s) and allowing them to refill with soft water. START-UP PROCEDURE / 21
