Installation
Select a Location
When choosing a location for your timer, consider the following:
● Choose location near a power source (if hard wiring) or
electrical outlet (applicable only to U.S. retail timers)
● Ensure operating temperatures are not below 32° or
above 158° Fahrenheit (below 0° Celsius or above 70°
Celsius)
● Place it away from direct sunlight if possible
● Ensure at least 9” of space to the left of the sprinkler
timer box for the door to swing open after installation
● Locate the timer where there is easy access to sprinkler
wire (from valves). If mounted in an outdoor location,
shut the compartment door to keep the timer safe from
weather damage.
To lock: insert the key and turn clockwise to the locked
position
Installation
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 (included) 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 preformed
holes located in lower back cabinet. See figure 2
Installation
Connect Electrical Power
Indoor Locations – Insert the power cord into
an 110V electrical outlet.
Outdoor Locations – If a covered Ground
Fault Interrupter (GFI) outlet is available, insert
the power cord into the 110 volt outlet. If no
outlet is available, the timer must have the
wiring permanently installed (*see figure 5)
Installation
Activate Battery
One Lithium CR2032 battery (included) is required to retain the program in memory during power
loss. Annual replacement is recommended.
Remove the plastic strip to activate the pre-installed battery.
(See page 12 for battery replacement)
Note: The battery alone will not operate
the valves in your sprinkler system. The
sprinkler timer has a built-in transformer
that must be connected to an AC voltage
source.

●Why is the timer not working on my orbit irrigation system?
Check the connection to the docking port to ensure the timer is plugged in properly.
Try removing the timer and inserting it into the docking port, pushing down until you
hear a click. If you are still not getting power, the timer may be defective

●Do water timers need electricity?
Manual sprinklers don't need electricity to run. You simply have to turn them on and
off as needed. There are also solar-powered irrigation systems that operate directly
from your water source. Conversely, automatic sprinkler systems do need electricity
to function, especially the irrigation timers or controllers
●Do water timers reduce water pressure?
They vary in reliability and ease of operation, but the main problem with tap timers is that they
reduce water pressure, which cuts down on the number of sprinklers or drippers you can
successfully operate

●Does water pressure change over time?
7 Reasons for Changes to Your Water Pressure - HVAC Plumbing ...
The flow of water into your home is controlled by a pressure regulator. If it fails, due to age or
damage, water flows unimpeded into the lines, leading to lower pressure throughout the home.
Low water pressure can be caused simply because too many people are trying to use it at the
same time.
