General and Commercial Installation Checklist
16. Cycle timer into backwash position. Turn manual knob so that the micro switch rides on the first set of pins.
— In this position the tanks switch (lower piston) and the control valve moves to the backwash position
(upper piston).
— Wait until the positioning of upper and lower pistons stops before advancing the timer further. If advanced
too fast the control will not home into the In Service position (it will not advance to any other position). To
correct this, rotate the manual knob back to In Service and start again into backwash.
. NOTE:
Once valve positions itself into the backwash cycle, the homing circuit locks in.
17. With all the air backwashed, slowly cycle the timer to the brine position; rapid rinse; and brine tank refill.
Wait for the control drive motor to position itself in each cycle and stop, before advancing on to the next
position.
18. Once back in the In Service position, cycle the control valve again into the backwash position. The tanks
switch again, and air head backwashes out of the other tank. Cycle the control back to the In Service position.
Leave the timer in the open position. DO NOT insert meter cable yet.
NOTE: Two motors are available.
1/15 RPM has 82 minute regeneration time.
1/30 RPM has 164 minute regeneration time.
