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.

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.

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.
