STEP 9: Plug the transformer into a non-switched electrical outlet.
Be sure the control valve is in
the “Service” position. For OXY2 models the service indicator
should point to the time of day arrow (See figure 4a below).
OXY2E units are in service when the time of day is displayed above the gallons remaining
(see figure 6, page 10).
Open main supply valve or turn on power to the pump or private well system. Check for leaks
and correct as needed.
STEP 10: 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 filter tank. Once the tank is pressurized, place bypass fully in the
Service position (Figure 3, page 4).
STEP 11: Remove media fines by manually initiating regeneration.
For the OXY2 turn the manual backwash knob (Figure 4, page 8) clockwise until the drive gear
engages the program wheel and water begins flowing to drain. Immediately unplug the control
valve from the power outlet and leave the unit in backwash until the drain water runs clear.
Meanwhile, continue with the remaining steps.
For the OXY2E refer to page 12 for electronic timer operation. Once the unit is counting down
the backwash cycle time, immediately unplug the control valve from the power outlet and leave
the unit in backwash until the drain water runs clear. Meanwhile, continue with the remaining
steps.
