VERNON MANUFACTURING RECOMMENDS THAT A QUALIFIED TECHNICIAN PERFORM THIS WORK. ALL MACHINES SHOULD BE INSTALLED USING A DEDICATED CIRCUIT AND SURGE PROTECTION IN ACCORDANCE WITH ALL FEDERAL, STATE, AND LOCAL BUILDING CODES. CHANGES IN WIRING OR OBVIOUS SHORTING WILL VOID WARRANTY.
For safety, wiring between components should be mounted underground in plastic conduit.
Since each installation is different, no exit holes have been drilled for the power or valve wiring and no mounting hardware is furnished. Your installer will determine what is best for your application.
Reveal the key box terminal strip. Using the special key, unscrew the key bolts and remove the white locking bezel. The tagged wire pigtails are for reference during installation and can be discarded. Use the forked connectors (furnished) and crimp or solder them for final installation. If wires are not marked--CONNECT ALL WIRES COLOR TO COLOR.
Mount the pulser box close to the flow sensor. This distance should be no greater than the length of shielded cable that is furnished. This cable can be shortened as necessary but DO NOT CUT AND SPLICE THIS WIRE BACK TOGETHER. Regular wires from the pulser box to the Keytrol box should be 16ga.
Mount the paddle wheel flow sensor ahead of the valve. It MUST be straight pipe running a minimum of 10 times the ID ahead of the fitting and 5 times after. This is CRITICAL for accurate readings and is shown here.
2” pipe: Minimum of 20” ahead -- 10” after. Uses a “T” fitting with nylon insert.
3” pipe: Minimum of 30” ahead -- 15” after. Uses a saddle fitting with nylon insert.
4” pipe: Minimum of 40” ahead -- 20” after. Uses a saddle fitting with nylon insert.
THE NYLON FLOW SENSOR ADAPTOR MUST NOT BE REMOVED OR ALTERED IN ANY WAY.
Install the valve in your water line either horizontal or vertical. It is marked for direction of flow. Protect it from freezing. A gate valve (not furnished) mounted ahead of the water valve aids in cleaning and repair. Install the piping, valves, drains, back flow preventers and other devices in accordance with local codes. PLEASE NOTE: The open hole under the diaphragm must be open to air—DO NOT PLUG THIS HOLE.
GALLON REGISTRY: Be sure the person in charge of billing knows the following values.
2” valve: Each gallon registers on the appropriate user counter wheel.
3” valve: Every 10 gallons register on the counter wheel.
4” valve: Every 100 gallons register unless otherwise specified.
These values can be changed if needed. Please call for help.
LOCK OUT: For non-payment of account.
Individual customer lock out is provided by means of a 10-position switch mounted at the bottom of each 10-key segment. Access these switches by removing the white locking bezel as explained above. The DIP-switches can be actuated with a small object like a paper clip or retracted ball point pen. DO NOT USE A PENCIL. UP is ON (normal). DOWN is OFF (locked out).
