Specifications

IMPORTANT: Observe all state and local regulations. Hire or consult a licensed plumbing professional if required. The ELK-WSV2
Valve can be used indoor or outdoor, however it should always be located within an enclosure or behind a cover that will protect if
from physical damage or tamper. Although it does have a manual override shutoff handle, we still recommend it be installed after
any existing manual shutoff (i.e. between the water fixtures and the manual valve) as an added benefit for maintenance or servicing.
Do not remove the cover of the actuator unit. There are no user servicable components inside.
Be certain that all necessary fittings and tools are available. Check the existing pipe material (plastic, copper, galvanized, etc),
pipe diameter, and any special requirements that may be needed due to location of proposed mounting.
Step 1. Manually shut off the main water supply at the water meter and/or manual shutoff valve.
Step 2. Locate the building internal manual shut off valve (if present). This will generally be located very close to where the main
water pipe enters the building. Turn this valve OFF just in case the outside valve fails to hold back the water supply.
Step 3. Install the ELK-WSV2 into the main water line using appropriate fittings and materials.
Step 4. Connect the ELK-WSV2 to the 12 VDC electric controlling device per the following diagram.

This is a "fail safe" type of hookup. Relay is shown in the non-energized (Off)
position. When the Relay is energized (turned On) the Valve Open wire will be
supplied power. Should the Relay coil fail or its input power from the controller
turn off the Relay contacts will return to the Off position and the Valve Close
wire will be supplied power, provided the Input Power Supply is still working.

• A 12 VDC, 2.0 Amp min. power source is recommended for powering the ELK-WSV2. Nomimal current draw is generally
between 800ma and 1.5 Amps, but the valve can draw more power (up to 4.0 Amps) for a short duration if the valve sits idle
(unmoved) for a long time. This allows minerals to build up on the valve face, thus requiring more torque from the actuator
and more current draw. Maximum current draw of the actuator under the worst case condition is 4.0 Amps. One way to help
minimize or clear mineral buildup on the valve face is to periodically auto-cycle it once a week, month, etc.
• Install a four (4) conductor, 18 gauge minimum cable between the Valve and the electric control device. Splice the four (4)
wires (RED, BLACK, GREEN, WHITE) coming from the Valve to the four (4) conductors that go to the controlling device. Use
Gel filled “B” connector splicers and/or a junction box to protect the integrity of the splices.
Connecting the ELK-WSV2 to Relay OUT3 of the ELK-M1G or EZ8 Control:
Connect the ELK-WSV2 RED wire to the N/C (normally closed) terminal of Relay OUT3. When this Relay is Off (not energized)
the 12 Vdc + Pos will be connected through this wire, causing the valve to Close if it was open.
Connect the ELK-WSV2 WHITE wire to the N/O (normally open) terminal of Relay OUT3. When this Relay is On (energized) the
12 Vdc + Pos will be connected through this wire, causing the valve to Open if it was closed
Connect the ELK-WSV BLACK wire to the - Negative output of the 12 Vdc Power Supply.
OPTIONAL - Connect the ELK-WSV2 GREEN wire as desired. When the Valve is Closed this wire provides a POS (+) 12 Vdc
output which can be used to drive a status indicator or automation zone input as needed. Insulate this wire if not used.
