Fig. 9

13. The female end of the connector hoses is

designed to thread onto 3/4" pipe thread. Perform

appropriate plumbing to provide connections

from the water supply to the inlet hose/port and

from the outlet port/hose.

NOTE: The inlet port is identified with an arrow

pointing towards the softener controls. The outlet port

is identified with an arrow pointing away from the

softener controls. These connections may be made

before the pressure reducing valve.

14. Insert tubing provided into the drain port on the

back of the cabinet and run it to an appropriate

drain. Be sure to provide a “air gap” between the

end of the tubing and the top of the drain.

NOTE: Drain line length should not exceed 8 feet

vertical and 30 feet horizontal from the softener.

15. Insert tubing provided into the overflow port on

the back of the softener and run drain lower than

the cabinet connection to provide a gravity drain

in the event of a internal cabinet leak.

Fig. 10

16. Review the meter disc selection chart and the

water analysis provided. If no water analysis is

provided test the water supply.

17. To test the water supply, use the water analysis

test kit available through Pro Products Inc. The

recommended kit is #2401 Field Analysis Kit. To

order the test kit contact Pro Products at 800-

285-9176 or visit www.ProProducts.com.

18. Determine the correct number disc. DISC

SELECTION

NOTE: Both the WS-40 and the WS-80 have a #4

meter disc installed at the factory. If this is not correct

disc for your application, locate meter disc kit and

REPLACE DISC.

19. Remove brine valve assembly from cabinet to set

float cup.

A. Disconnect tubing from brine valve elbow by

holding collet and pulling tubing straight

away.

Fig. 11

B. Remove the brine valve assembly by lifting

straight up.

C. Set it on a flat surface, to mesure height of

float cup.

D. Measure from bottom of brine valve to top of

float cup.

WS-80 1.4 lb. 6.5"

E. Reinstall brine valve into the cabinet.

NOTE: Do not drop brine valve into drum. Dropping

may lower float cup, resulting in an improper setting.

20. To install salt alarm system remove paper lining

from back of salt alarm connector box.

Fig. 13

21. Remove plastic lining from Velcro® backing

located on back of salt alarm controller.

Fig. 14

22. Remove four screws securing back cover to salt

alarm controller.

29. Add a clean grade of salt at this time. Higher

grades of Pelletized Salt for impurities and

solubility should be used.

NOTE: Do not use rock salt or solar salt.

30. Open inlet valve slowly allowing system to

pressurize.

31. Water and air will be expelled from drain until

system is completely pressurized.

32. A manual regeneration should be started to

purge air and color from softening system. This

is done by pushing down on actuator with a

Phillips screwdriver and rotating clockwise slowly

until pressure is felt.

33. Continue slowly until internal water flow is heard

at softener valve. The softener will automatically

run through a regeneration. This process should

be repeated in 12 to 15 minutes to flush other

resin tank.

34. Check for plumbing leaks.

35. Check unit for proper operation.

DISC SELECTION

DISC SELECTION WS-40/80

The amount of hardness removed (in compensated gpg) will be based on the amount of brine and the meter disc

selected.

1. Determine the compensated hardness. This requires a hardness test and an iron test on raw water at the

application site. Compensated hardness is calculated by multiplying the ferrous iron (in ppm) by 3 and adding

it to the grains of hardness.

2. To test the water supply, use the water analysis test kit available through Pro Products Inc. The recommended

kit is #2401 Field Analysis Kit. To order the test kit contact Pro Products at 800-285-9176 or visit

www.ProProducts.com.

3. Determine the salt setting. The salt setting is determined by taking the compensated hardness (calculated in

step 1 above) and using the specification table for model WS-40 or WS-80.

4. Verify the float cup setting. Use specifications for the WS-40 or WS-80 to determine the correct setting the

float cup height.
