INSTALLATION
Water Pressure
A minimum of 20 psi/1.38 bar/138 kPa water pressure is
required for control valve to operate effectively.
CAUTION
Water pressure is not to exceed 125 psi (8.6 bar),
water temperature is not to exceed 150°F (65°C),
and the unit cannot be subjected to freezing
conditions.
Electrical Facilities
An uninterrupted alternating current (AC) supply is required.
NOTE: Other voltages are available. Please make sure your
voltage supply is compatible with your unit
before installation.
NOTE: All electrical connections must be connected
according to local codes. Be certain the electrical
outlet is uninterrupted.
Existing Plumbing
Condition of existing plumbing should be free from lime and
iron buildup. Piping that is built up heavily with lime and/
or iron should be replaced. If piping is clogged with iron, a
separate iron filter unit should be installed ahead of the water
softener.
Location Of System And Drain
You must have an air gap on the drain line to prevent back flow
of drain water into the system. Follow local plumbing codes.

Installation Locations
FOR DRY LOCATIONS ONLY.
Bypass Valves
Always provide for the installation of a bypass valve if unit is
not equipped with one.
Installation Instructions
1. Place the softener tank where you want to install the unit
making sure the unit is level and on a firm base.
2. During cold weather, the installer should warm the valve to
room temperature before operating.
3. All plumbing should be done in accordance with local
plumbing codes.
4. Cut the distributor tube 0.12” (3 mm) below top of tank
then chamfer the tube to prevent cutting the pilot o-ring.

5. Lubricate the distributor o-ring seal and tank o-ring seal.
Place the main control valve on tank. Only use silicone
lubricant that is approved for use with potable water.
6. Solder joints near any plastic or rubber components
must be done prior to installation. Leave at least 6 inches
(15 cm) between any plastic parts and solder joints.
Failure to do so could cause damage to plastic or rubber
components.
7. Plumber tape is the preferred sealant to be used on the
drain fitting. Plumbers tape can be used on any type of
connection while pipe dope can only be used on metal to
metal connections. Installations with multiple valves may
be run through a common drain line flow control
8. Make sure that the floor is clean beneath the salt storage
tank and that it is level.
9. Place approximately 1 inch (25 mm) of water above the grid
plate. If a grid is not utilized, fill to the top of the air check
(Figure 3) in the salt tank. Do not add salt to the brine tank
at this time.
10. On units with a by-pass (or a three-ball valve by-pass),
place in by-pass position. Turn on the main water
supply. Open a cold soft water tap nearby and let run
a few minutes or until the system is free from foreign
material (usually solder) that may have resulted from the
installation. Once clean, close the water tap.
11. Install power supply (routing cable through backplate
and using cord restaint to secure power cord). Refer to
dimensional drawing for power cord entry point.
12. Program the timer as desired.
13. Slowly open the inlet ball valve letting water flow into the
mineral tank. When water flow stops, put the control valve
into the backwash position. Leave control valve in the
backwash position until clear water is running smoothly
out the drain line.
IMPORTANT:
Use thread sealant intended for use with
stainless steel connections and approved for use with potable
water. To reduce the risk of seizing or galling, a nickel
impregnated PTFE (polytetrafluoroethylene) thread sealing
tape is recommended.

FLECK 2815 Control Valve Service Manual • 5
Meter Dome and Union Orientation
Control valves outfitted with an electromechanical timer and
stainless steel water meter include a special male x female
threaded stainless steel union to insure proper installation and
operation of the water meter.
The location of this union in relation to the
control valve and water meter is critical for
proper operation. DO NOT omit or substitute
this special union; it positions the meter dome
at the correct distance from the control valve
and allows re-positioning the water meter
dome for proper operation.
1. Apply a suitable thread sealant to the male threads of the
union and meter body.
2. Thread the union into the OUTLET port of the control valve,
then thread the meter into the union. See illustrations
below.
3. Rotate the water meter body so the meter dome is at the
12 o’clock position. Loosen the nut on the union to facilitate
this if required. Once in position, tighten the union nut.
4. Connect the meter cable to the open port in the center of
the meter dome.
5. Continue with the installation of the control valve.

14. Manually advance the control valve through the cycle
positions (checking for leaks at each position) and
stopping at the brine fill position. Let the brine fill cycle
automatically complete and the control valve advance to
the service position to ensure the proper amount of water
has been let into the brine tank. Add salt to the brine tank
as needed. Make sure the salt level is always higher than
the water level to maintain the correct salt dosage.
15. Open outlet ball valve. To purge air from the plumbing
system, open each faucet starting from the closest location
to the control valve to the farthest faucet location.

Timer Setting Procedure
How To Change The Length Of The Backwash Time
The program wheel as shown in Figure 6 is in the service
position. As you look at the numbered side of the program
wheel, the group of pins starting at zero determines the length
of time your unit will backwash.
For example, if there are six pins in this section, the time of
backwash will be 12 min. (2 min. per pin). To change the length
of backwash time, add or remove pins as required. The number
of pins times two (x2) equals the backwash time in minutes.
How To Change The Length Of Brine And Rinse Time
1. The group of holes between the last pin in the backwash
section and the second group of pins determines the length
of time that your unit will brine and rinse (2 min. per hole).
2. To change the length of brine and rinse time, move the rapid
rinse group of pins to give more or fewer holes in the brine
and rinse section. Number of holes times two (x2) equals
brine and rinse time in minutes.
How To Change The Length Of Rapid Rinse
1. The second group of pins on the program wheel determines
the length of time that your water conditioner will rapid
rinse (2 min. per pin).
2. 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 times two (x2) equals the rapid rinse time
in minutes.
How To Change The Length Of Brine Tank Refill Time
1. The second group of holes in the program wheel determines
the length of time that your water conditioner will refill the
brine tank (2 min. per hole).
2. To change the length of refill time, move the two pins at the
end of the second group of holes as required.
3. The regeneration cycle is complete when the outer
microswitch is tripped by the two pin set at end of the brine
tank refill section.
4. The program wheel, however, will continue to rotate until
the inner micro switch drops into the notch on the
program wheel.
