After the AC valve or battery operated controller, add a 3/4" screen filter with 155-mesh (model D55). The
screen filter is used to protect the drip system. Next, add a preset 25-PSI pressure regulator (model D46P) or
adjustable pressure regulator (model PRV075) for operating under higher pressure. The pressure regulator is
used to lower the pressure to the suggested operating pressure for micro sprinklers and micro sprayers. Follow
with a 3/4" swivel adapter (model 50001) to the drip tubing or 3/4" PVC thread x slip adapter to the PVC line.
Start the installation from a faucet or hose thread
1.
If an automated system is preferred, install a hose end timer.
2.
Test the hose end timer and make sure that it is working correctly, then program it. To the hose end timer, add
a backflow device (model D45), then a 25-PSI pressure regulator (model D46) and follow with a 3/4" swivel
adapter with a screen (model C34). If water quality is a concern, we highly recommend using a 3/4" filter with
155 mesh (model D57A).
Product installation
1.
Using the drip tubing as the main lateral or as a sub lateral, lay out the drip tubing per your layout drawing.
Secure the drip tubing to the ground using stakes (model R60). Secure the drip tubing to the ground in key
areas and add more stakes as you unroll the drip tubing. Add stakes every 20'-30' and at the end of each
section, or as needed. An extra 1% of drip tubing length should be added to each lateral to compensate for
contraction at low temperature.
2.
Throughout the installation and per your drawing layout, add, if needed, 1/2" fittings such as tees (model C35)
and elbows (model C36), leaving the end of the drip tubing open. To install the 1/2" compression drip fittings,
cut the drip tubing with a hand pruner, being careful to keep dirt from entering the line. Hold the fitting in one
hand and the drip tubing in the other and force the drip tubing into the compression fitting by wiggling it from
side to side.
3.
The micro sprayers are installed along the drip tubing at varying or at specific intervals. The distribution
uniformity of water from the micro sprayers along the line depends on the incoming pressure, number of micro
sprayers used per lateral, and the length of the laterals. Special care should be taken to ensure high uniformity
of water along the laterals by not exceeding the product recommendations (see chart).
4.
To install the micro sprayer, cut a length of 1/4" micro tubing, not to exceed four feet (vinyl - models B38 for
50' and B38100 for 100', or poly - models B38P for 50' and B38100B for 100'). To the micro tubing end,
insert a 1/4" barb (models H80A for pack of 10 and H80B for pack of 50). To the other end of the micro
tubing, thread the micro sprayer. Use a long stake to secure the micro sprayer to the ground, keeping the micro
sprayer head at a minimum of 8" to 10" above ground for best coverage. Punch a hole into the drip tubing
