EZ FLO Fertilize Responsibly CBV Series Installation guide

* IMPORTANT *
PLEASE READ INSTRUCTIONS
BEFORE INSTALLING THE SYSTEM.
·Do not connect to an irrigation system that is not protected by an approved
back flow prevention device such as a pressure vacuum breaker or
reduced pressure zone back flow preventer.
·Do not install if pressure exceeds 100 PSI
·Follow all local plumbing codes
·Use only with non-hazardous products
·Minimize exposure to direct sunlight to maximize service life
·Protect against impact from foreign objects
All EZ-FLO systems have been specifically designed and engineered to be installed by
a professional irrigation or landscape contractor. Improper installation or use could
cause risk of water contamination due to back flow or tank rupture. Failure to follow all
safety instructions and warnings could result in serious bodily injury. Improper
installation or use of the system voids all warranties.

System Installation
Typical installation
The system is normally installed in a valve box, connected to the main line of the irrigation
system after the back flow preventer and before the sprinkler valves. One unit will feed both
drip and sprinkler zones that are downstream from the connection point.
Step 1 - Locate the installation point.
Connection must be made after an approved back flow prevention device. It is preferable to
have the tank cap above the installation point in the sprinkler line if possible but it is not
required for efficient operation. The connection can be made either vertically or horizontally
in the sprinkler main line.
Step 2 - Shut off water by closing a valve at the back flow preventer or in the main
line upstream from the connection point. Relieve the pressure from the line at the exhaust
valve on the back flow preventer or by manually opening a sprinkler valve.

Step 3 - Cut out a section of pipe slightly larger than the cut out length of the ball valve
coupling. Determine the length of the cutout by measuring the length from socket to socket
inside the ball valve coupling. If the space for the coupling is cut too large it may prevent the
pipe and the coupling from forming a solid seal. (Unions may be used for easier retrofit
installations.)
Step 4 - Glue the ball valve coupling into the line. The pipe should fit into both ends of
the ball valve coupling and seat against the ball valve coupling socket. Be sure that the blue
fitting is closer to the back flow preventer than the green fitting and that the flow direction of
the water matches the flow direction arrow on the side of the ball valve coupling.
Step 5 - Attach tubing to the ball valve coupling. Press the black tube over the
blue fitting on the ball valve coupling. Press the clear tube over the green fitting on
the ball valve coupling. Put tubing clamps over the tubing below the barbed end of
the fitting and squeeze them until they are tightly secured.

Connect System to Irrigation Lines
Step 6 - Connect tubing to tank cap by removing the blue and green connector
nuts from the bypass fitting by turning them in a counter clockwise direction.
(Attach bypass fitting to tubing for later use). Connect the blue connector nut to
the water in side of the tank cap. Connect the green connector nut to the fertilizer
out connection on the cap. Turn the water on to the system.
1. Shut off valves in the off position
2. Turn water on at back flow preventer
3. Connect blue connector to water in connection on cap
4. Connect green connector to fertilizer out connection on cap.
Set Flow Adjustment
Step 8 - Set the flow rate by adjusting the ball valve coupling and the
adjustment knob on the tank cap. (The ball valve coupling will only require
adjustment at initial startup.)
1. With the cap adjustment setting in the fast position, turn on the
sprinkler or drip zone with the average gallons per minute flow rate.
2. Slowly close the ball valve very slightly, until you can see fluid
movement or color in the clear fertilizer out line.
3. Set the cap adjustment knob to the desired feed rate.
4. Turn off the sprinkler or drip zone.
