3. Connect the Transformer
•
Find the two sockets at the bottom of the docking port
labeled “24VAC.” (See Figure 6)
•
Insuring the transformer is not plugged in; insert one of
the two power leads from the transformer into each
terminal socket using the phillips screwdriver to depress
the terminal button (this allows for wire insertion or
removal).
•
Plug in the transformer.
WARNING: Do not link two or more sprinkler timers together with
one transformer.
4. Connect Valve Wires to Timer, Pump Start and Master
Valve Terminals
A. Wire the Electric Valves
NOTE: 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.
•
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 a single “common” sprinkler wire. This
is usually white.
IMPORTANT:
All wires should be joined together using wire
nuts, solder and/or vinyl tape. For additional protection to
waterproof connections, an Orbit
®
grease cap can be used.
•
Next, connect the remaining wire from each valve to a
separate colored sprinkler wire.
•
To avoid electrical hazards, only one valve should be
connected to each station.
IMPORTANT
: The wire can be buried in the ground.
However, for greater 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 future digging or trenching. (See Figure 7)
