-X3™ Scale Prevenon Technology-
This water heater is equipped with X3
™
Scale Prevention Technology to inhibit scale formation within the
heat exchanger tubing of this unit. Part of the X3
™
Technology’s anti-scale protection comes from the special
X3
™
Cartridge media. The X3
™
Cartridge must be installed into the manifold located on the underside of the
heater cabinet prior to operation of the unit (shown as follows). The X3
™
system is designed to be hassle-free;
eliminating the need to drain the heater for installation, removal, or replacement of the cartridge. X3
™
Scale
Prevention Technology reduces the formation of scale in the heat exchanger, extending the operating life of the
unit in typical potable water installations. Specific water conditions may impact the efficiency of X3
™
, such as
excessive iron (>0.3 mg/l). Consult a water quality expert to determine if your water is within acceptable X3
™
and EPA guidelines.
