CHECK WATER
PRESSURE AND
PUMPING RATE
Two water system conditions must be checked carefully
to avoid unsatisfactory operation or equipment damage:
1.
Minimum water pressure required at the softener
tank inlet is 30 psi.
2.
The pumping rate of your home’s well pump must at
least equal to the required backwash flow rate of your
model (see Specifications on Page 6 for backwash
flow rates).
TO MEASURE THE PUMPING RATE OF YOUR
PUMP, FOLLOW THESE INSTRUCTIONS:
A.
Determine the cycle time. Make certain no water is
being drawn. Open spigot nearest pressure tank.
When pump starts, close spigot and measure time (in
seconds) to refill pressure tank (when pump shuts
off). This figure represents cycle time.
B.
Determine drawn-down time. With the pressure tank
full, draw water into a container of known volume and
measure the number of gallons drawn until the pump
starts again. This is draw-down.
C.
Determine drawn cycle time. Divide the draw down
time by cycle time and multiply the result by
60 to arrive at the pumping rate in gallons per
minute (gpm).
To aid in your calculation, insert the data in the
following formula:
DRAW-DOWN________ (gals)
÷ CYCLE TIME______________x 60 (seconds)
= PUMPING RATE______________ (gpm)
EXAMPLE:
DRAWDOWN is 6 gals; CYCLE TIME is 53 secs; then,
PUMPING RATE equals: 6 gals ÷ 53 secs x 60 = 6.8 gpm
SEE SPECIFICATIONS ON PAGE 6
FOR MINIMUM FLOW RATES.
.
DETERMINE THE CORRECT
LOCATION OF THE WATER
CONDITIONING EQUIPMENT
Determine the best location for your water softener, bearing in mind the
location of your water supply lines, drain line and 120 volt AC electrical
outlet. Subjecting the softener to freezing or temperatures above 43°C
(110°F) will void the warranty. Review the various conditions below to
determine a proper location:
1.
Locate as close as possible to the water supply source.
2.
Locate as close as possible to a floor or laundry tub drain.
3.
Locate in correct relationship to other water conditioning
equipment (see Fig. 1 on Page 10)
4.
Softener should be located in the supply line before the water heater.
Temperatures above 120°F damage softeners.
5
. Do not install a softener in a location where freezing temperatures
occur. Freezing may cause permanent damage to this type of
equipment and will void the factory warranty.
6.
Allow sufficient space around the unit for easy servicing.
7.
Determine if additional plumbing is required if your water source is a
community water supply, a public water supply or you wish to bypass
water used for a geothermal heat pump, lawn sprinkling,
out-buildings or other high demand applications, refer to Fig. 1.
8.
Keep the softener out of direct sunlight. Heat build up from direct
sunlight may soften and distort plastic parts.
TOOLS REQUIRED FOR
INSTALLATION:
Two adjustable wrenches
Additional tools may be required if modifications to home
plumbing are required.
Plastic inlet and outlet fittings are included with the softener. 3/4”
or 1” pipes to and from the softener fittings are recommended to
maintain full valve flow. You should maintain the same or larger
water supply pipe sizes as the softener inlet and outlet pipe sizes.
Use copper, brass, or PEX pipe and fittings.
Some codes may also allow PVC plastic pipe. Refer to local codes.
ALWAYS INSTALL THE INCLUDED BYPASS VALVE, OR 3 SHUT-OFF
VALVES. Bypass valves let you turn off water to the softener for
repairs, but still have water in the house pipes.
5/8” OD drain line is needed for the valve drain. A 10’ length of
hose is not included with some brands
If the plumbing system is used as the ground leg of
the electric supply, continuity should be maintained
by installing ground straps around any nonconductive
plastic piping used in installation.
NOTE
If there is a severe loss in water pressure when the
softener unit is initially placed in service, the softener
tank may have been laid on its side during transit. If this
occurs, backwash the softener to “reclassify” the media.
NOTE
