drop the transformer or have the cable too taut. The
transformer is only suitable for
internal use only .
For full understanding of the water softener we
recommend that the instruction manual be fully read
before installation and commissioning of the softener
by undertaken.
IMPORTANT: A NUMBER OF VALVE
COMPONENTS ARE LOCKED INTO POSITION
WITH
EASILY REMOVABLE CLIPS .
ENSURE ALL LOCKING CLIPS ARE CORRECTLY
IN POSITION BEFORE PRESSURISING THE
SOFTENER. ENSURE THAT IT IS POINTED OUT
TO ALL RELEVANT PERSONNEL THAT THE
LOCKING CLIPS MUST NOT BE REMOVED
WHILST THE SYSTEM IS UNDER WATER
PRESSURE.
Note: All electrical connections must be connected
according to local codes.
Install grounding strap on metal plates.
Bypass Valve
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 WS1 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,
including a diagnostic position that allows service
personnel to work on a pressurised 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.
The bypass body and rotors are glass filled Noryl (or
equivalent) 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 flow
direction of the water. The plug valves enable the
bypass valve to operate in four positions.
1.
Normal Operation Position : 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 position also allows the control
valve to isolate the media bed during the
regeneration cycle. (Figure 1)
2. Bypass Position : The inlet and outlet handles
point to the centre of the bypass, the control
valve is isolated from the water pressure
contained in the plumbing system. Untreated
water is supplied to the plumbing system. (Figure
2)
3. Diagnostic Position : The inlet handle points in
the direction of flow and the outlet handle points
to the centre 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.(Figure 3)
4. Shut Off Position: The inlet handle points to the
centre of the bypass valve and the outlet handle
points in the direction of flow, the water is shut off
to the plumbing system (i.e. plumbing connection
somewhere in the building bypasses the system).
