Toro 53682 User manual

Connecting the Valve Wires (Figure 3)
Step 1-Route a multi-wire, direct-burial sprinkler
cable from the sprinkler timer to the valves. If the
cable run is less than 800', 18 AWG wire is suffi-
cient. For distance from 800' – 2000', 14 AWG wire
is recommended.
Step 2-Using wire splice connectors, attach either
wire from each valve solenoid to the white cable
wire. This wire is designated as the valve “Common
Wire.”Connect the remaining wire from the sole-
noid to one of the color-coded wires.
Important: All wire splices must be properly insu-
lated to prevent a short circuit or corrosion
from occurring. Installing grease caps or waterproof
connectors is recommended.
Step 3-At the timer, connect the control wires from
valves to the numbered terminals in the desired
operating sequence. Connect the valve common
wire to the valve common terminal.
Step 4-Using the timer’s manual control feature,
test the operation of each valve.
Finishing the Installation (Figure 4)
Step 1-Once valve operation has been successfully
tested with the timer, control wires can be buried
and a valve box installed.
Manual Operation (Figure 5)
• Manually open the valve by turning the bleed
screw counterclockwise 1/2 turn. To close the valve,
turn the bleed screw clockwise. Do not over-tighten!
Note: The valve may take several seconds to shut off when operated manually.
•To adjust flow, (model 53682 only) turn the flow control handle clockwise to
decrease or counterclockwise to increase flow.

- 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. timer. Both valve models feature
1" female-threaded inlet and outlet and manual
bleed control which enables the valve to be
operated without the use of the timer. In addi-
tion, the 53682 valve model features manual
flow control adjustable to zero flow.
The in-line valve is generally installed below
grade, grouped with other valves in a manifold
arrangement and housed in a protective valve box.
Important: 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 infor-
mation regarding the type of backflow prevention device required for safe operation.

Installation Procedure
Note: To ensure ease of installation and optimum valve performance, please read
through the following instructions completely before starting the installation procedure.
Step 1-Route 1" schedule 40 PVC pipe from the backflow preventer or system shut-
off device to the valve location. Flush the supply line thoroughly!
Caution: Dirt, rocks and debris entering the valve can damage the valve and/or
cause the valve to malfunction.
Step 2-The diagrams on the next page illustrate the two most commonly recom-
mended methods of installing valves in a manifold arrangement. Referring to instal-
lation Method A or B, follow one of the installation procedures.

•Installation Method A (Figure 1)
Step 1-Apply three complete wraps of Teflon®tape to the slip/thread adapters.
Caution: Use only Teflon tape on threaded connections. Pipe dope and other
types of pipe thread sealants can damage plastic threads.
Step 2-Install a slip/thread adapter into each end of the valve and tighten securely.
Step 3-Cut a 4" length of 1" schedule 40 PVC pipe for each valve.
Step 4-Using PVC primer and cement, assemble the valve and PVC components as
shown, aligning the tee fitting perpendicular to the valve. Repeat this procedure for
each valve in the manifold.
Note: The last valve in the manifold can be connected with a 90°elbow instead of
a tee. However, if future expansion of the sprinkler system is expected, use the tee
fitting and a 4" section of 1" schedule 40 PVC pipe capped on the end. This enables
the main line to be easily connected to additional downstream valves.
Step 5-Using 4" sections of 1" schedule 40 PVC pipe, connect the valve assemblies
together to create the manifold, making sure the valves are aligned during assembly.
Step 6-Ensure the end of the supply line is dry and free of burrs. Cement the
manifold to the main line.
Step 7-Allow the cemented connections to cure for a minimum of one hour (or
per the cement manufacturer’s directions) before applying water pressure. If no
leaks occur after pressurization, begin connecting the sprinkler zone piping using
1" class 200 PVC pipe.
•Installation Method B (Figure 2)
Step 1-Apply three complete wraps of Teflon tape to both ends of a 4" long 1" PVC
threaded pipe nipple and the slip/thread adapter.
Caution: Use only Teflon tape on threaded connections. Pipe dope and other
types of pipe thread sealants can damage plastic threads.
Step 2-Install the pipe nipple to the valve inlet and tee fitting and tighten securely,
aligning the tee perpendicular to the valve. Install the slip/thread adapter into the
valve outlet and tighten securely. Repeat this procedure for each valve in the manifold.
Note: The last valve in the manifold can be connected with a 90°elbow instead of
a tee. However, if future expansion of the sprinkler system is expected, use the tee
fitting and a 4" section of 1" schedule 40 PVC pipe capped on the end. This enables
the main line to be easily connected to additional downstream valves.
Step 3-Using 4" sections of 1" schedule 40 PVC pipe, connect the valve assemblies
together to create the manifold, making sure the valves are aligned during assembly.
Step 4-Ensure the end of the supply line is dry and free of burrs. Cement the mani-
fold to the main line.
Step 5-Allow the cemented connections to cure for a minimum of one hour (or
per the cement manufacturer’s directions) before applying water pressure. If no
leaks occur after pressurization, begin connecting the sprinkler zone piping using
1" class 200 PVC pipe.
