Placing Water Conditioning System Into Operation (continued)

Caution: If your system is a 255A (Alternating) go to “Quick Cyling the Control for 255A Systems”.

Quick Cycling the Control 255L and 255P

It is required that the control be quick cycled to specific regeneration cycles when placing the conditioner into operation. This will ensure that all of the air in the tank and valve is purged. The process also provides a check for leaks and functioning of the brine system. Please perform the following steps for quick cycling the control, before proceeding to start-up.

1.With the control in the treated water position, Press and hold the REGEN button on the controller for 5 seconds. This will initiate a manual regeneration. The control will display a solid hourglass indicating that the motor and camshaft are turning to the backwash cycle (C1). When the control reaches the backwash cycle, the total regeneration time remaining will be displayed. Pressing the SET button will display the specific cycle time remaining.

2.Press and release the UP and SET buttons to move the control to the Regenerant Draw cycle (C2).

3.Repeat Step 2 to advance to each cycle.

Before the final filling of the media tank with water check that:

–the nearest water faucet is completely closed.

–the valve drain line is properly routed to a drain

–the regenerant tank is empty and the regenerant hose is connected to the valve

–the water supply valve is off.

Note: The control can be sent directly back to the treated water position from any regeneration cycle. Press the UP and SET buttons (about 5 seconds) until the hourglass icon begins flashing. The control will now skip all remaining regeneration cycles.

255 Alternating and parallel tank systems have one Logix 764 control that is mounted on tank 1. Tank 2 has a blank faceplate and the valve is controlled by the Logix 764 control on tank 1.

4.Add water to the regenerant tank.

A.With a bucket or hose add approximately 4 gallons (15 liters) of water to the regenerant tank.

B.If the tank has a salt platform in the bottom of the tank, add water until the water level is approximately 1 inch (25 mm) above the platform.

Note: It’s recommended that you do not put regenerant into the tank until after the control valve has been put into operation. With no regenerant in the tank, it is much easier to view water flow and motion in the tank.

5. Press and hold the button on the controller for 5 seconds. This will initiate a manual regeneration.

The control will display a solid hourglass indicating that the motor and camshaft are turning to the backwash cycle (C1). When the control reaches the backwash cycle, the total regeneration time remaining will be displayed. Pressing the SET button will display the specific cycle time remaining.

6.While the controller is in cycle C1 (Backwash), open the water supply valve very slowly to approximately the ¼ open position. Water will begin to enter the media tank. Any air remaining will begin to be purged to drain as the media tank fills with water.

WARNING: If opened too rapidly or too far, media may be lost out of the tank into the valve or the plumbing. In the ¼ open position, you should hear air slowly escaping from the valve drain line.

When all of the air has been purged from the media tank (water begins to flow steadily from the drain line), open the main supply valve all of the way. This will purge the final air from the tank.

Allow water to run to drain until the water runs clear from the drain line. This purges any debris from the media bed.

7.Check Regenerant Draw.

A.Quick cycle the control to the C2 regenerant draw/slow rinse position .

Note: As you advance through each cycle there will be a slight delay before you can advance to the next cycle. There will be a pause after the regenerant draw and slow rinse cycles. This cycle (C4) is a repressurization cycle and is designed to allow the water pressure to equalize on each side of the valve discs. Allow the control to repressurize (3 minutes) before cycling the control to the regenerant tank refill position.

B.C2 will be displayed. With the control in this position, check to see that the water is being drawn out of the regenerant tank. The water level in the regenerant tank should recede very slowly.
