STEP 10: Use polyethylene drain line tubing provided ( NO VINYL TUBING ) to run drain line from control
valve discharge fitting to floor drain or sump pit capable of handling the backwash rate of the
filter (refer to specifications and flow rate on page 12).
DISCHARGE END OF THE DRAIN
LINE MUST BE FIRMLY SECURED! There must be an air gap at the end of the drain line to
prevent siphoning of waste water and meet plumbing code. Total length of drain line should
be 15’ or less. AVOID OVERHEAD DRAINS.
STEP 11:
Place bypass in the “Bypass” position (refer to Figure 3 below). Open main supply valve or turn
on power to pump on private well systems.
STEP 12: Plug the power cord into an un-switched electrical outlet.
STEP 13: Initiate a manual regeneration by turning the Manual Backwash Knob clockwise until the knob
engages the program wheel. You should hear one click.
This is the “Backwash” position.
Then, unplug the control valve from the electrical outlet to prevent it from advancing
automatically.
STEP 14: Refer to Figure 3 (page 6) for appropriate bypass valve operation. Rotate bypass lever of
stainless steel bypass ¼ of the way to Service or until air and/or water begins to flow slowly to
drain.
