INSTALLATION
Water Pressure
A minimum of 20 pounds (1.4 bar) of water pressure is required
for regeneration valve to operate effectively.
Electrical Warnings & Caution Statement
An uninterrupted alternating current (A/C) supply is required.
NOTE: Othervoltagesareavailable.Pleasemakesureyour
voltagesupplyiscompatiblewithyourunit
beforeinstallation.
Grounding Instructions
This appliance must be grounded. In the event of a malfunction
or breakdown, grounding will reduce the risk of electric shock
by providing a path of least resistance for electric current. This
appliance is equipped with a cord having an appliance-grounding
conductor and a grounding plug. The plug must be plugged
into an appropriate outlet that is installed and grounded in
accordance with all local codes and ordinances.
Improperconnectionoftheappliance-
