Page 7: Drain Line Connection
Drain line connection NOTE : Standard commercial practices are expressed here. Local codes may require changes to the following suggestions. Check with local authorities before installing a system. 1. If the backwash flow rate exceeds 5 gpm (22.7 Lpm) or if the unit is located 20-40 feet (6.1-12.2 m) from drain, use 3/4-inch (1.9 cm) tubing. -
Page 8: Overflow Line Connection
Overflow line connection In the event of a mal function, the regenerant tank overflow will direct “overflow” to the drain instead of spilling on the floor.This fitting should be on the side of the cabinet or regenerant tank. Most tank manufacturers include a post for the tank overflow connector. -
Page 9: Start-Up Of Your Softener
START-UP OF YOUR SOFTENER Preliminary check of hydraulic parameters of the valve This step must have been done by your OEM. You need to check that there is no mistake. In fact, every setting stored in the electronic is largely dependant of hydraulic parameters (injector/backwash) installed on the valve. - Page 10 4. Fill the media tank with water. A. While the controller is in cycle C1 (backwash), open the water supply valve very slowly to approximately the 1/4 open position. B. When all of the air has been purged from the media tank (water begins to flow steadily from the drainline), open the main supply valve all of the way.

C. Observe the water being drawn from the regenerant tank for at least three minutes. If the water level does not recede, or goes up, reference the Troubleshooting section. 8. If the water level is receding from the regenerant tank you can then advance the controller back to the treated water (C0) position by pressing SET and UP buttons simultaneously to advance the controller to the C0 position. - Page 12 Specific day of week regeneration (740 only) ● To change the controller to regenerate on specific days, set the number of days between regeneration to zero. After this has been completed, the arrow on the left side of the display will be pointing to regeneration time/day.
- Page 13 Amount of regenerant used per regeneration ● If the installation is a 3-cycle filter, skip to Filter Backwash Time. The amount of regenerant does not apply. The Logix series controllers are set-up to automatically calculate the capacity of the system by multiplying the resin/media volume that was entered earlier into the controller, with the regenerant amount entered by the dealer/installer.

Page 15: Step 4 - Capacity
Step 4 - Capacity The 740 controller is designed to estimate capacity of the system by multiplying the initial resin/media volume by the regenerant amount programmed in under “Amount of regenerant used per regeneration”. An estimated total system capacity is displayed in kilograins (kilograms CaCO ) that can be removed by the fully regenerated media bed. -
