This wire is designated as the valve “Common Wire.” Connect the remaining wire from the solenoid to one of the color-coded wires. Important: All wire splices must be insulated with grease caps or similar waterproofing devices. Step 3- At the timer, connect the control wires to the numbered terminals in the desired operating sequence and the valve common wire to the common terminal. Step 4- Using the timer’s manual control feature, test the operation of each valve. Manual Operation (Figure 4) • Bleed Screw (external bleed): To open the valve, turn the Bleed Screw counterclockwise one full turn or until water begins discharging from the port. Note: Removing the bleed screw is not required but can be removed to help flush debris from the upper diaphragm area. To close the valve, turn the bleed screw clockwise until it stops. Do not over-tighten! • Bleed Handle (internal bleed): To open the valve, move the Bleed Handle counterclockwise to the stop. To close the valve, move the handle clockwise until resistance is felt. Do not over-tighten! • Flow Control Adjustment: With the valve operating, use a small screwdriver to turn the flow control screw clockwise to decrease flow or counterclockwise to increase flow. Note: The flow control screw requires approximately seven turns to adjust from maximum to minimum flow. Caution: Do not use the flow control to shut off the valve. Do not force the flow control screw past the end of normal adjustment travel. Damage can occur. The Toro Promise — Limited One-Year Warranty The Toro Company and its affiliate, Toro Warranty Company, pursuant to an agreement between them, jointly warrants, to the owner, each new piece of equipment against defects in material and workmanship for the period of one year from the date of purchase. Neither Toro nor Toro Warranty Company is liable for failure of products not manufactured by them even though such products may be sold or used in conjunction with Toro products. During such warranty period, we will repair or replace, at our option, any part found to be defective. Return the defective part to the place of purchase. Our liability is limited solely to the replacement or repair of defective parts. There are no other express warranties. This warranty does not apply where equipment is used, or installation is performed, in any manner contrary to Toro’s specifications and instructions, nor where equipment is altered or modified. Neither Toro nor Toro Warranty Company is liable for indirect, incidental or consequential damages in connection with the use of equipment, including but not limited to: vegetation loss, the cost of substitute equipment or services required during periods of malfunction or resulting non-use, property damage or personal injury resulting from installer’s negligence. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. All implied warranties, including those of merchantability and fitness for use, are limited to the duration of this express warranty. Some states do not allow limitations of how long an implied warranty lasts, so the above limitation may not apply to you. This warranty gives you specific legal rights and you may have other rights which vary from state to state. - Installation Guide - The Toro 1" in-line electric valves are designed for use in an automatic sprinkler system controlled by a 24 V a.c. sprinkler system timer. The valves feature manual flow control adjustable down to zero flow and manual bleed controls which enable the valve to be operated without the use of the timer. The 53707 valve is designed for slip-fit pipe connections and model 53709 features female-threaded inlet and outlet. These valves are generally installed below grade, grouped with other valves in a manifold arrangement and housed in a protective valve box. Important: These valves do not provide backflow protection. A backflow prevention device installed between the 1" in-line valve(s) and the water source point of connection is required in most areas to prevent back-siphoning of contaminants through the sprinkler system into the potable water supply. The Toro 1" Pressure Vacuum Breaker (PVB), model number 53300, is specifically designed for this purpose. Before connecting your irrigation system to the potable water supply, consult with your local water utility department for information regarding backflow prevention requirements. Where local water pressure exceeds 70 psi, a presure regulator should be used. (See Uniform Plumbing Code, Se...
