Note: Please use only single strand, color-coded irrigation wire for your installation.
1.
2.
Connect the wire from valve #1 to the terminal slot marked 1, connect the wire from valve
#2
to the terminal slot #2 and so on until all valves are connected.
Connect the one common wire from the valves to the terminal marked “COM”.
(See Figure 1 ). Back the terminal screw out until head is 1/8" (3.2mm) above plastic
partition. Expose approximately 1/2" (13mm) of bare copper from the end of the wire to
reduce short circuiting of two adjacent wires. Slip wire through hole under screw and
tighten screw until wire is secure.
3.
Connect the transformer wires to the two screws marked 24 VAC.
Caution: Wire only one valve to each terminal screw. Wiring more than one valve
per terminal may result in damage to the timer. Do not use valves that exceed 0.25
amps maximum output holding current. Also, if using more than one timer, do not
share common wires. Run a separate common wire for each timer.
Connecting a Pump Start Relay
Note: When a pump is to be operated by the timer, a pump start relay must be used and
should be set up by an electrician. The relay coil should be connected to the master valve
output terminal marked MV and the common terminal COM at the timer. The relay contacts
will be connected to the pump start terminals and must be rated for use with your particular
pump. (See Figure 2). In addition, a high pressure relief mechanism is recommended. See
your pump dealer for more information.
Caution: The timer must be mounted at least 15 feet (4.5m) away from both the
pump start relay and the pump. Do not drive the pump directly from the timer. The
relay coil must be rated for 24 V a.c. at 250 mA (maximum).
Note: When all connections have been completed, install the front access cover and plug
the timer transformer into the wall outlet.

Lawn and Garden readers have rated Toro Model 53603 Sprinkler Irrigation Owners Manual 4.0 out of 4.0 based on 1 product reviews. The manual was exactly what I needed to reinstall my well-aged lawn sprinkler controller. After much time spent looking for the manual, just as I was about to give up, your site popped up during what turned out to be my final search. Believe me, I will return and I will pass your site on to my friends who might face a similar situation of losing a product manual in the future.
