Installation
Required Tools
• Phillips Screwdriver
• Wire Strippers
1. Select a Location
When choosing a location for your timer, consider the
following:
• Choose a location near an electrical outlet .
• ensure operating temperatures are not below 32° or
above 158° Fahrenheit (below 0° Celsius or above 70°
Celsius) .
• locate the timer where there is easy access to sprinkler
wire (from valves) .
2. Mount the Timer
• Use the mounting template (included) to mark the
mounting screw location on the wall . See figure 1
• Install a No . 8 screw into wall in the upper template
location . leave the screw head protruding 1/8” (3mm)
from wall . Use expanding anchors (included) in plaster
or masonry, if necessary, for a secure hold .
• slip the timer over protruding screw (using keyhole slot
in back of timer) . See figure 2
• Drive a No . 8 screw through one of the two pre-formed
holes located in lower corners of the cabinet . See figure 2
3. Connecting the Timer to Valves
Wiring Electric Valves
Taking the sprinkler wire, strip 1/2” (12 mm) of the
plastic insulation off the end of each individual wire .
Connect one wire from each valve (it doesn’t matter
which wire) to the “Common” sprinkler wire (usually
white in color) . Next connect the remaining wire from
each valve to a separate colored sprinkler wire .
See figure 3
Note: The maximum loading for each station/pump is 250mA
(one valve), the maximum loading for the timer is 500mA.

Wiring Electric Valves
If the distance between the sprinkler timer and valves is
under 700’ (210 m), use Orbit
®
sprinkler wire or 20 gauge
(AWG) plastic jacketed thermostat wire to connect the
sprinkler timer to the valves. If the distance is over 700’ (210
m), use 16 gauge (AWG) wire.
Important:
The wire can be buried in the ground; however,
for more protection wires can be pulled through PVC pipe
and buried underground. Be careful to avoid burying the
wires in locations where they could be damaged by digging
or trenching in the future.
All wires should be joined together using wire nuts, solder,
and/or vinyl tape. In wet environments like a valve box it
is recommended to use Orbit Grease Caps or Speed Seals
to prevent corrosion of the connection and for protection
from water infiltration.
Connecting Sprinkler Wires to the Timer
Taking the sprinkler wire, strip 1/4” (6 mm) of the
plastic insulation off the end of each individual wire .
Connect the “Common” sprinkler wire (usually white in
color) to the terminal labeled “CoM” . Next connect the
remaining wires to a separate terminal . See Figure 4
To avoid electrical hazards and damage to the timer,
only one valve should be connected to each station . See
