Unit Description
SFES’s ScaleCutter Water Conditioning System is a unique product providing
superior limescale prevention and corrosion control. The unit conditions the
water resulting in greatly decreased mineral scale adhesion to the inner
surface of the heat exchanger
ScaleCutter works by:
* Keeping scale-causing minerals in solution inhibiting limescale formation.
* Changes the shape of precipitated limescale preventing accumulation.
* Coats wetted surfaces with a micro-thin layer that provides corrosion control.
* Helps soften and remove existing limescale over time.
In many cases, the ScaleCutter Water Conditioning Systems offer many of the
same advantages as conventional water softening systems, except at a lower
cost with little professional maintenance.
Prior to Installing System:
1. The ScaleCutter water conditioning system must be installed on a cold-water line prior to the tankless water heater.
The unit will treat either the hot side only, or the whole house.
2.
3. Determine the flow direction of the incoming water line. The unit is shipped with mounting bracket attached with
the inlet port on the left side. If needed, remove and reverse the mounting bracket for right side inlet port
configuration.
4. It is recommended that a 3-way by-pass be used on all installations in order to isolate the system for maintenance.
The use of unions is also recommended. Refer to bypass diagrams.
5. Observe water pressure. If pressure exceeds 125 psi, use a pressure regulator prior to the system.
6. Securely mount the system using supplied bracket whenever possible.
7. The system must be installed with the cartridge and sump directly below the feed head. Do not install sideways or
upside down.
8. Install the system where the housing is in an accessible location for cartridge change. Allow a 2” space under the
cartridge housing in order to unscrew it from the head.
Connection and Start- Up:
1. Turn off water supply.
2. Use either Teflon tape and/or pipe dope on 3/4” male threaded fittings prior to connecting them to the female
threaded ports on the system head. Do not over tighten the fittings into the ports.
3. Do not sweat fittings close to the system head unless precautions are taken against excessive heat.
4. Use a back up next to the head if a compression fitting is used to make inlet/oulet connections.
Do not install the ScaleCutter in an area where water leakage of the unit or connections will result in damage to the
area adjacent to the appliance or to lower floors of the structure. When such locations cannot be avoided, it is
recommended that a suitable drain pan, adequately drained, be installed under the ScaleCutter Unit.

Important Note: Do not install the ScaleCutter unit where it is exposed to direct sunlight.
Installations where a recirculating hot water loop is used, the ScaleCutter unit must be installed on the
cold water inlet line only.
Do not
install in unconditioned spaces or outdoors where unit could freeze.
