Greenway Water Conditioners are precision built, high quality products. These units will deliver
conditioned water for many years to come, when installed and operated properly. Please study this
manual carefully and understand the cautions and notes before installing. This manual should be
kept for future reference. If you have any questions regarding your water conditioner, contact your

PreinsTallaTion insTruCTions:
The manufacturer has set the water treatment unit’s sequence of cycles, cycle times, salt dose, exchange
capacity, and gallon capacity. For water softeners the salt dose refill time has been preset.
The dealer should read this page and guide the installer regarding hardness, day override, and time of
regeneration, before installation:
For the installer , the following must be used:

2.Bypass Position: The inlet and outlet handles point to the center of the bypass. The system is
isolated from the water pressure in the plumbing system. Untreated water is supplied to the
building (Fig. 2).
3. Diagnostic Position:Theinlethandlepointstowardthecontrolvalveandtheoutlethandlepointsto

while not allowing water to exit from the system to the building (Fig. 3).Thisallowstheservicetechnician
to draw brine and perform other tests without the test water going to the building.

systemcallsforit,usuallyreferredtoasmanualregeneration.Theremaybeaperiodofheavywater

To initiate a manual regeneration immediately, press and hold the regeN button for three seconds. The
systemwillbegintoregenerateimmediately.Thecontrolvalvemaybesteppedthroughthevarious
regeneration cycles by pressing the regeN button.
2. Regeneration Mode: Typically a system is set to regenerate at a time of
no water use. If there is a demand for water when the system is regenerating,
 untreatedwaterwillbedelivered.Whenthesystembeginstoregenerate,
the display will change to include information about the step of the
regeneration process and the time remaining for that step to be completed.
 Thesystemrunsthroughthestepsautomaticallyandwillresetitselftoprovide
treated water when the regeneration has been completed.
To initiate a manual regeneration at the preset delayed regeneration time, when the regeneration time
option is set to Normal or Normal + oN 0, press and release regeN. The words regeN toDay will flash on the
display to indicate that the system will regenerate at the preset delayed regeneration time. If you pressed the
regeN button in error, pressing the button again will cancel the request.

Once a manual regeneration is initiated, the unit will go into the FILL
position. This position allows water to enter the brine tank until it
 reachestheproperlevel.Oncethispositioniscomplete,youwill

and at no time during this process will you be without treated water.
4. Power Loss: If the power goes out for less than two hours, the system will automatically reset itself. If
an extended power outage occurs, the time of day will flash on and off which indicates the time of day
should be reset. The system will remember all other settings.
5. Error Message: If the word error and a number are alternately flashing on the
displayrecordthenumberandcontactthedealerforhelp.Thisindicatesthatthevalve

 betweenregeneration),themanufacturerrecommendstheuseofsolarsaltforbestresults.Thebrinetankis
manufactured for the use of solar, pellets or rock salt. If pellet or rock salt is used, a cleaning of the brine tank
 everysixmonthsisrecommended.Ifthedrysaltstoragefeatureisnotbeingutilized,blocksaltmaybeused.
CAUTION: The manufacturer does not recommend the use of any resin cleaners, nor placement of any resin
cleaners into the brine tank. This may be harmful to the water softener and for human consumption. Consult
dealer for proper cleaning instructions.

air is expelled and water is running at drain, open inlet to control and place into the diagnostic
mode (Fig. 3 on page 2).
CAUTION: If water flows too rapidly, it could result in loss of media to
the drain. When the water is flowing steadily to the drain without the
presence of air, slowly open the inlet valve. Check drain that it can
receive the flow of water. Restore power.
