INSTALLATION & STARTUP CONTINUED
Figure 5 Program Wheel
19. 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.
20. 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.
21. 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.
Valve To Tank Installation
1. Spin the valve onto the tank, ensuring the threads are not
cross-threaded.
NOTE: All Fleck valves are right-hand threads, or
®
clockwise, to install
2. Rotate the valve freely without using force until it comes
to a stop (this position is considered zero).
3. Rotate the valve clockwise from zero, between 1/4-turn
and 1/2-turn (see "Figure 6").
NOTE: If lubricant is required, a silicone compound
is strongly recommended. Dow Corning
Silicone Compound (available from Pentair), is
recommended for best possible results. Dow
Corning 7 Release Compound is used in the
®
manufacture of Pentair control valves. The use of
other types of lubricants may attack the control's
plastic or rubber components. Petroleum-based
lubricants can cause swelling in rubber parts,
including o-rings and seals.

Setting the Regeneration Cycle Program
The Regeneration cycle program on the water conditioner is
preset at the factory. However, portions of the cycle or program
time may be lengthened or shortened for local conditions or
system design.
1. Expose cycle program wheel by grasping timer in lower
right hand corner and pulling. This releases snap retainer
and swings timer to the left
NOTE: Meter cable must be removed from meter dome before
opening timer.
2. Remove the program wheel by grasping program wheel
and squeezing protruding lugs towards center. Lift program
wheel off timer. Switch arms may require movement to
facilitate removal.
3. Return timer to closed position by engaging snap retainer
in back plate. Make certain all electrical wires locate above
snap retainer post.
Changing Length of the Backwash Time
Looking at the numbered side of the program wheel, the group
of pins starting at zero determines the length of time the
unit backwashes.
Example: If there are six pins in this section, the time of
backwash is 12 minutes (2 minutes per pin). To
change the length of backwash time, add or remove
pins as required.
The number of pins multiplied by two equals minutes
of backwash.
Changing Length of Brine and Rinse Time
The group of holes between the last pin in the backwash section
and the second group of pins determines the length of time that
a unit will brine and rinse (2 minutes per hole).
To change the length of brine and rinse time, add or remove
pins in the rapid rinse group of pins to increase or decrease the
number of holes in the brine and rinse section.
The number of holes multiplied by two equals minutes of brine
and rinse.
Changing Length Of Rapid Rinse
The second group of pins on the program wheel determines the
length of time the water conditioner rapid rinses (2 minutes per
pin). To change the length of rapid rinse time, add or remove
pins at the higher numbered end of this section as required.
The number of pins multiplied by two equals minutes of
rapid rinse.
NOTE: Program wheels with 0–82 minute cycle times, use one
minute per pin or hole to set Regeneration times. The
layout of pins and holes on the program wheel follow
the same procedure as on this page.
