WS2H and WS3 Drawings and Service Manual
6. INLET/OUTLET PLUMBING:
Connect to a supply line downstream of outdoor spigots. Install inlet and
outlet shutoff valves for the control valve; see top view drawings for control valve inlet and outlet locations.
Installation of a three valve bypass is recommended. If using plastic
fi
ttings ground the water conditioner
per local electric codes. If an external water meter is used, install the water meter on the outlet side of the
control valve. It is recommended that the meter assembly be installed horizontally or in a down
fl
ow vertical
position to reduce turbine bearing wear. The turbine assembly may be orientated in any direction. Remove
the cover and drive bracket and thread the water meter cord through the hole in the back plate. Reinstall the
drive bracket. Weave the cord through the strain relief on the backplate and connect the end to the three prong
connector labeled FLOW on the printed circuit board. Re-install the cover.
7. Drain:
Verify that the drain can handle the backwash rate of the water conditioner. Correctly size the drain
line and install an appropriately sized drain line
fl
ow control. For WS2H and WS3 valves a drain line
fl
ow
control are NOT supplied with a valve. For WS2H valves the drain outlet is 2” Female NPT or BSPT threads
or 2.5” groove lock connection. For WS3 valves the drain port is 3” Female NPT or BSPT, no groove lock
connection. If using copper, solder joints near the drain must be done prior to connecting the drain line
fl
ow
control
fi
tting. Leave at least 6” (152.4 mm) between the drain line
fl
ow control
fi
tting and solder joints to
prevent heat from damaging the
fl
ow control. Avoid elevating the drain line above the control valve where
possible. Discharge the drain line through an air gap to a receptacle in accordance with local plumbing codes.
IMPORTANT: Never insert a drain line directly into a drain, sewer line, or trap. Always allow an air
gap between the drain line and the receptacle to prevent back siphonage.
8. Regeneration:
If the control valve is to be used to regenerate the water conditioner with brine (saturated
salt solution) or other regenerants. The WS2H and WS3 control valves regenerant port has a 1” 90° Male NPT
threaded outlet connection that swivels 360°. To ensure acceptable operation of the injectors use 1” pipe to
connect to the brine tank. Smaller drain line
fl
ow controls may result in the injector performance not matching
the injector graphs. Use an adequately size drain line
fl
ow control to ensure proper brine draw.
See Table 3 for injector order number and size for tank diameter. An over
fl
ow drain line from the regenerant
tank that discharges into an acceptable drain is recommended, as a regenerant over
fl
ow could damage
furnishings or the building structure. Connect a line to the over
fl
ow
fi
tting on the regenerant tank. If an
over
fl
ow
fi
tting is not already installed on the regenerant tank, install one. Do not elevate the over
fl
ow drain
line. Discharge the over
fl
ow drain line through an air gap to a receptacle in accordance with local plumbing
codes.

Actual injector size used may vary depending on the design and application of the system. Injectors in table are sized for a typical
down
