The manufacturer has preset the water treatment unit’s sequence of cycles, cycle times, salt dose,
exchange capacity and salt dose refill time.
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:
• Program Installer Settings: Hardness, Day Override (preset to 12 days), and Time of
Regeneration (preset to 2 a.m., with brine tank refill to occur four hours prior; see Operating
Displays and Instructions for more details)
• Read Normal Operating Displays
• Set Time of Day
• Read Power Loss & Error Display
For the homeowner, please read operating displays and instructions.
The bypass valve is typically used to isolate the control valve from the plumbing system’s water pressure
in order to perform control valve repairs or maintenance. The 1" full flow bypass valve incorporates four
positions, including a diagnostic position that allows a service technician to have pressure to test a system
while providing untreated bypass water to the building. Be sure to install bypass valve onto main control
valve, before beginning plumbing. Or, make provisions in the plumbing system for a bypass. The bypass
body and rotors are glass-filled Noryl
®
and the nuts and caps are glass-filled polypropylene. All seals are
self-lubricating EPDM to help prevent valve seizing after long periods of non-use. Internal “O” Rings can
easily be replaced if service is required.
The bypass consists of two interchangeable plug valves that are operated independently by red arrow
shaped handles. The handles identify the direction of flow. The plug valves enable the bypass valve to
operate in four positions.
