Mounting Instructions

Check flow direction with the arrow on the valve body.
Ensure correct alignment of connecting pipes.
Do not use the valve stem to turn the unit onto the piping.
Mount with coil in horizontal or vertical position, not upside-down.
Coil can be oriented 360 degrees by releasing the nut on top.
Install in a protected area from rain and water splashes.
Do not use PTFE tape in connections.
Install an external filter upstream of the valve.
Provide protection against accidental touch of hot coil.

Maintenance

Coil Replacement: Disconnect power, remove nut, replace coil, reconnect and reassemble.
Seal Cleaning: Remove coil, unscrew stem, clean seal with oil and compressed air, reassemble components.

Valve Identification
Model numbers indicate valve type, connections, coil type, supply voltage, and cable length.
