IMPORTANT: Do not use petroleum based lubricants.
Use only 100% silicone based lubricant products when
installing any MAYTAG
lubricants can cause plastic components to fail over time.
NOTE: Several fitting packages are available to connect
the valve to the water plumbing. See "Bypass Fitting
Packages".

Bypass Valve Operation
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
bypass valve is particularly unique in the water treatment
industry due to its versatility and state of the art design
features. The full flow bypass valve incorporates four
positions: normal, bypass, diagnostic mode and shut off
mode; the diagnostic position allows service personal
to work on a pressurized system while still providing
untreated bypass water to the facility or residence. Its
completely non-metallic, all-plastic design allows for
easy access and serviceability without the need for tools.
Radial seals handle side-to-side and up/down minor
plumbing misalignments, connections need only hand
tightening.
The bypass body and rotors are glass-filled Noryl¹ (or
equivalent) and the nuts and caps are glass-filled poly-
propylene. All seals are self-lubricating EPDM to help
avoid the valve from seizing after long periods of non-
use. Internal o-rings can easily be replaced if service

®
system should be installed by
is required. One internally lubricated o-ring on the rotor
creates less friction.
The bypass consists of two interchangeable plug valves
that are operated independently by red arrow-shaped
handles. The handles identify the flow direction of the
water. The plug valves enable the bypass valve to
operate in four positions.
1. Normal Operation: The inlet and outlet handles point
in the direction of flow indicated by the engraved
arrows on the control valve. Water flows through the
control valve during normal operation and this posi-
tion also allows the control valve to isolate the media
bed during the regeneration cycle. (See Figure 11)
2. Bypass Operation: The inlet and outlet handles point
to the center of the bypass, the control valve is isolat-
ed from the water pressure contained in the plumbing
system. Untreated water is supplied to the plumbing
system. (See Figure 12)
3. Diagnostic Mode: The inlet handle points in the
direction of flow and the outlet handle points to the
center of bypass valve, system water pressure is
allowed to the control valve and the plumbing system
while not allowing water to exit from the control valve
to the plumbing. (See Figure 13)
4. Shut Off Mode: The inlet handle points to the center
of the bypass valve and the outlet handle points in the
direction of flow, the water is shut off to the plumbing
system. If water is available on the outlet side of the
softener it is an indication of water bypass around the
system (i.e. a plumbing connection somewhere in the
building bypasses the system). (See Figure 14)
