SIGNATURE SERIES
-Drain Line Connection-
1. Pull out clip and remove drain line assembly located on the left side of control valve. Remove drain line hose barb and
wrap threads with Teflon tape. Reinstall drain line hose barb. Caution: Hand tighten only!! Replace drain line assembly
and reinstall clip.
2. Install 1/2” I.D. drain line tubing (not included) from hose barb to an open drain. A 4” gap between the end of the drain
line and the open drain is required to prevent waste water backflow. Keep the drain line as short as possible. An
overhead drain line can be used if necessary, but should discharge below the control valve. A siphon trap (taped loop)
at the outlet of the drain line is advisable to keep the drain line full and assure correct flow during regeneration.
Elbows or other fittings must be kept at a bare minimum.
Note:
Where the drain line is elevated above the control valve or exceeds 20 feet in length, 3/4” I.D. drain line tubing
should be used.
-Brine Line and Overflow Connection-
1. Position brine tank on a smooth, level surface near the softener resin tank. If necessary, the brine tank can be placed at
a higher level than the resin tank, but never at a lower level.
2. Install one end of 3/8” O.D. by 1/4” I.D. brine line tubing (included with unit) to compression fitting located on left side of
control valve.
3. Remove brine tank cover.
4. Remove cap from brine well.
5. Insert opposite end of brine line through outer hole in brine tank.
6. Connect brine line to push lock fitting on safety brine valve located inside brine well. Replace brine well cap.
7. Install 1/2” I.D. drain line tubing (not included) to the overflow fitting on brine tank located just below the brine line.
8. Run the opposite end of brine tank drain line to a suitable drain.
9. Install optional RK15 Res-Care Feeder in brine tank per instructions. (Sold Separately!)
Note:
The brine tank drain line is gravity flow and must discharge below the overflow fitting.
Caution:
Do not TEE to the main drain line from control valve.
Notice:
The brine overflow is provided as a back-up in the event the safety float shut-off should fail, allowing the brine
tank to overfill. This drain connection would then carry the excess water to the drain and prevent flooding of the
floor. Therefore, no liability will or can be assumed by the manufacturer of the softener should this occur.
-Electrical Connection-
1. Connect the power supply to the control valve and plug into a 115 volt / 60 Hz receptacle.
-Installing Battery Back Up-
1. Remove the rear cover.
2. Install a 9 volt battery. Refer to page 3, item 3 of the Signature Series Service Manual.
- Pressurizing The System -
1. Make certain Signature Series Control Valve is in
SERVICE
position.
2. Slowly rotate bypass valve to the
SERVICE
position.
3. Open the nearest faucet to evacuate air from plumbing lines.
4. Check for leaks! If water is observed leaking from bottom of bypass, close and open bypass lever several times to
seat o-rings.
5. After air is evacuated from plumbing lines, close bypass (position of bypass lever is perpendicular to the direction of
pipes)
Note :
Salt settings are pre-set at the factory for the maximum shown on the capacity charts.
Warning :
Do not reduce salt settings below 9 lbs. as the water level in the brine tank will not reach the grid plate.
