Connecting 1/4 in. barbed fittings:
To install your 1/4 in. barbs, tees or elbows, push the
micro tubing over each of the barbed ends. Soaking
the micro tubing in warm water will make it softer and
the fittings easier to install.
Using the punch:
To insert drippers, micro sprinklers and
1/4 in. fittings into 1/2 in. poly tubing, hold
the poly tubing in one hand and apply just
enough pressure with the punch to puncture
the poly tubing.
Installing drippers into 1/4 in. micro tubing:
For plants far from the poly tubing, first insert a 1/4 in. barb or tee into
one end of the 1/4 in. micro tubing, then insert the barb into the punched
hole in the 1/2 in. poly tubing and run the micro tubing to the plant. Next
insert the barbed inlet of the dripper into the end of the micro tubing and
secure with a stake.
INITIAL SySTeM START-Up
q
Before turning the system on for the first time, leave all 1/2 in. poly
tubing ends open and turn on your water and allow it to run freely for a
few minutes. This will flush out any dirt that may be in the line.
w
Close the end of the poly tubing by using a “figure 8” hose end. Check
to see the drippers are operating correctly and that no leakage is
occurring.
e
Use stakes to secure the poly tubing to the ground.
Repairing or plugging a Hole on 1/2 in. poly Tubing:
If leakage occurs on the 1/2 in. poly tubing near the base of a dripper,
simply remove the dripper and insert a goof plug to close the hole and
reinsert the dripper in a different location.
Installing drippers to 1/2 in. poly tubing:
Drippers are installed by punching a hole in 1/2 in. poly tubing and
snapping in the barbed side of the drippers. If the poly tubing is
buried, the drippers should always be located above the ground. This
is achieved by inserting a 1/4 in. barb or tee into the poly tubing and
running 1/4 in. micro tubing to the surface where the dripper is installed
into the end of the micro tubing.
TypICAL INSTALLATION
Connecting and installing 1/2 in.
compresion fittings:
To install your 1/2 in. fittings, cut the poly tubing
with a hand pruner, being careful to keep dirt from
entering the line. Push the poly tubing into the
compression fitting by wiggling it as you apply force.

w
e
Begin your installation at the water source by attaching the backflow
preventer
q
to your faucet, then attach the 25 PSI preset pressure
regulator
w
to the backflow preventer. Connect the hose adapter
e
to your pressure regulator and insert the poly tubing into the
swivel compression adapter. If you wish to automate the system, you
can use a DIG battery operated controller (Model 9001D, 9001EZ or
7001) available at a store near you.
Next, lay down your 1/2 in. poly tubing. If you plan to leave it above
the ground, allow the poly tubing to sit in the sun before installation,
making it easier to work with. Use stakes to secure the poly tubing to
the ground. If you are burying the poly tubing, dig a trench about 6 in.
from the roots of the plants. A shallow trench, 5-8 in. deep is all that
is needed to keep the poly tubing safe from cultivation practices. Do
not bury the end of the poly tubing, allow it to remain on the surface
for periodic flushing.
