Installation Guide

Example – We have determined that our home
has a “Main Line” size of 3/4” with
a “Static Water Pressure” of 60 psi. Based on
this information, and using the Quick
Reference, we see that we cannot use
more than three Voyager II
®
sprinklers in
the same zone.
STEP 2: Identifying Sprinklers in a Zone
Begin grouping large area heads, ensure you do not ex-
ceed your “Maximum Heads per zone number.”
Example – Since we determined (in our example above) that 3 Voyager II
®
heads
is the maximum zone capacity, we grouped all large area heads into 2 zones.
Step 3:
Medium and Small Area Head Zones
Repeat steps 1 & 2 to determine and identify zones for Medium Areas Heads. Repeat again for
Small Area Heads.
Step 4: Number Each Zone
• Assign a number to each zone.
