STEP 6: Shut off water at main supply. Relieve pressure by opening nearest faucet. On private well
systems, turn off power to pump and drain pressure tank. SHUT OFF POWER OR FUEL
SUPPLY TO WATER HEATER.
STEP 7: Cut main supply line as required to fit plumbing to inlet and outlet of bypass valve. DO NOT
PLUMB INLET AND OUTLET BACKWARDS. Piping should support control valve in an
upright position. Do not apply heat to any fitting attached to the bypass or control valve.
STEP 8: Use rigid drain line or polyethylene tubing ( 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 8).
DISCHARGE END OF THE DRAIN
LINE MUST BE FIRMLY SECURED! Failure to properly secure the drain line will result in the
drain line “whipping” and possibly flooding the area causing water damage. 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 9: Use a garden hose or bucket to fill the media tank with water through the fillport. Ensure
media has been cleaned from fillport threads and install cap securely with wrench provided.
STEP 10: Be sure the control valve is in the “Service” position (refer to timer operation for instructions).
The bypass valve should be in the “Bypass” position. Open main supply valve or turn on
power to pump on private well systems.
STEP 11: Open bypass valve ¼ of the way allowing unit to pressurize slowly. It is normal for air to be
trapped in the top part of the aeration tank. Once tanks are pressurized, fully open bypass
valve to the “Service” position.
STEP 12: Set the backwash frequency for every third day (refer to timer operation for instruction).
Ensure that the skipper wheel is set so that the filter will not backwash for two more days. This
will allow the filter media time to saturate with water. Depending on the media used, subjecting
the filter to backwash flow rates within 24 hours of installation may flush media to the drain.
STEP 13: Set the current time of day on the timer (note AM and PM).
STEP 14: Check for leaks and correct as necessary.
STEP 15: Turn power or fuel supply back on to water heater.
