How Your Scaleless Stack Water Filter Works

Water Enters through the inlet of the control valave passes through the media bed (Activated Carbon) contained in the
mineral tank. This reduces the chlorine content of your municipally supplied water and reduces taste and odor of the
water. The water then passes through the stack distributor where a scaleless media and goes through the outlet of the
control valve to the house.

The Scaleless system provides protection from scale formation throughout the home.

The Scaleless system can be installed at the point of entry to treat your entire home, both hot and cold water, or
it can be located directly before a water heater or other device (e.g. sauna, etc) that requires protection from hard
water.

Scaleless reduces or eliminates scale formation on internal and external plumbing surfaces as well as reducing
spotting and streaking normally associated with hard water.

Scaleless prevents scale by transforming the normal dissolved hardness minerals into undissolved crystal
micro-particles. These crystals stay suspended in the water and have a greatly reduced ability to react and attach
to surfaces like dissolved hardness does. Therefore the problem of internal buildup of scale in pipes, water heat-

ers and on xtures and glass is greatly reduced.

Scaleless is not a water softener – Low or phosphate-free cleaning products are recommended to achieve opti­mum results.

Modern surfactant or detergent based, liquid soaps are preferred over oldfashioned caustic solid soaps.

Unlike softened water, Scaleless treated water maintains the benecial essential mineral content of your water

and is safe to drink.

Scaleless Benets

• Chemical Free Scale Prevention. Cost savings and environmental benets.

• Virtually Maintenance Free. No salt bags or other chemicals to buy, transport and store.

• No Electricity, no wastewater, completely self-contained.

• Benecial minerals retained for more healthful drinking water.

• Improves the efciency of water-using appliances.

• Simple installation – no electrical and drain hookup

• Safe for landscaping and lawn watering. No need to costly bypass plumbing

• Compatible with all on-site and community wastewater treatment systems

• Not subject to water softener restrictions and “bans

The scaleless stack is recommended to be replaced every three years.

In normal operation, the Time of Day display will alternate being viewed with the Days Remaining Display the day Volume
Remaining display will count down from a maximum value to zero or (---). Once this occurs, a regeneration cycle will be
initiated at the Set Regeneration Time.

Control Operation During Regeneration

In regeneration, the control will display a special regeneration display. In this display, the control will show the current

regeneration step number the valve is advancing to or has reached and the time remaining in that step. The step number

displayed will flash until the valve has completed driving into this regeneration step position. Once all regeneration steps
have been completed, the valve will return to Service and resume normal operation.

Example Less than 6 minutes

remaining in Regen

5

Step Rapid Rinse

Pushing the Extra Cycle Button during a regeneration cycle will immediately advance the valve to the next cycle step

position and resume normal step timing.

Control Operation During Programming

The control will only enter the Program Mode with the valve in Service. While in the Program Mode, the control will
continue to operate normally, monitoring water usage and keeping all displays up to date. Control programming is stored
in memory permanently, eliminating the need for battery back-up power.

Time Clock Delayed Control

A Time Clock Delayed Control regenerates the system on a timed interval. The control will initiate a regeneration cycle
at the programmed regeneration time when the number of days since the last regeneration equals the regeneration day

override value.

2

Day of the Week Control

This control regenerates the system on a weekly schedule. The schedule is defined in Master Programming by setting
each day to either “off” or “on.” The control will initiates a regeneration cycle on days that have been set to “on” at the

specified regeneration time.

Control Operation During a Power Failure

The SXT includes integral power backup. In the event of power failure, the control shifts into a power-saving mode. The
control stops monitoring water usage, and the display and motor shut down, but it continues to keep track of the time and

day for a minimum of 48 hours.

The system configuration settings are stored in a non-volatile memory and are stored indefinitely with or without line
power. The Time of Day flashes when there has been a power failure. Press any button to stop the Time of Day from

flashing.

If power fails while the unit is in regeneration, the control will save the current valve position before it shuts down. When
power is restored, the control will resume the regeneration cycle from the point where power failed. Note that if power
fails during a regeneration cycle, the valve will remain in it’s current position until power is restored. The valve system
should include all required safety components to prevent overflows resulting from a power failure during regeneration.

The control will not start a new regeneration cycle without line power. If the valve misses a scheduled regeneration
due to a power failure, it will queue a regeneration. Once power is restored, the control will initiate a regeneration cycle
the next time that the Time of Day equals the programmed regeneration time. Typically, this means that the valve will
regenerate one day after it was originally scheduled. If the treated water output is important and power interruptions are
expected, the system should be setup with a sufficient reserve capacity to compensate for regeneration delays.

Installation Instructions

All government codes and regulations governing the installation of these devices must be observed.

CAUTION: If the ground from the electrical panel or breaker box to the water meter or underground copper pipe is tied to
the copper water lines and these lines are cut during installation of the Noryl bypass valve and/or poly pipe, an approved

grounding strap must be used between the two lines that have been cut in order to maintain continuity. The length of the
grounding strap will depend upon the number of units being installed and/or the amount of copper pipe being replaced

with poly. See Figure 1.

In all cases where metal pipe was originally used and is later interrupted by poly pipe or the Noryl bypass valve as
in Figure 1 or by physical separation as in Figure 2, an

approved ground clamp with no less than #6

conductor must be used for continuity,

to maintain proper

metallic pipe bonding.

Check your local electrical code for the correct clamp and

cable size.

1. Determine the best location for your water filter, bearing

in mind the location of your water supply lines, drain
line and 120 volt AC electrical outlet. Subjecting the
filter to freezing or temperatures above 43°C (110°F)

will void the warranty.

Media Installation (When Necessary)

• For installation of stack distributor, remove the old

scaleless stack/ or conventional distributor tube from the

tank after removing the media from the tank. Install the

new Scaleless stack (come complete with lower basket
and distibutor tube). Cut grey distributor tube so that the
scaleless stack and control valve fits in the tank.

• Remove the valve from the mineral tank.

• Temporarily plug the open end of the riser tube to ensure

that no resin or gravel falls down into the distribution.

• Fill mineral tank one quarter full of water to protect

distribution during gravel installation.
