Waterco Commandomatic Ezysoft Manual For Use And Installation - 5. Start Up
5. START UP
When installation has been completed, the unit is ready to be placed into service. Proceed as
follows, while checking the unit for any leakages:
I. Place unit in bypass and turn on main water supply; open a cold water tap nearby and
allow water to run for a few minutes until all foreign material that may have resulted from the
installation is washed out; close the tap.
II. Slowly shift the bypass valve to the service position and secure it; allow water to completely
fill the resin tank.
III. Carefully open a cold water tap and allow water to run for at least 2 minutes to set the resin
bed and purge air from the system; close the tap.
IV. Fill the brine tank with water, higher than the air-check level.
V. Turn the timer knob clockwise past 30 min, to open the drain paddle; the valve is now
transferred to the brine/slow rinse position.
VI. Allow the valve to draw water from the brine tank until the air check closes.
VII. Place unit in bypass.
VIII. Add the appropriate amount of water to the brine tank.
IX. Add salt to the brine tank.
X. Shift bypass valve back to the service position.
XI. Turn the timer knob back counter clockwise to the OFF position, to close the drain paddle;
the valve is now transferred back to the service position.
5.1. ADJUSTING RESIDUAL HARDNESS WITH FACTORY BYPASS
I. Adjust the residual hardness of the water that leaves the softener, by means of the adjusting
screw, incorporated in the ‘outlet’ valve of the factory bypass:
• To raise the residual hardness: turn the screw counter clockwise; usually 1 turn corresponds
to a residual hardness of ± 40mg/L, 2 turns to ± 80 mg/L.
• To reduce the residual hardness: turn the screw clockwise.
