WARNING

Carefully Read These Instructions Before Use

WARNING

IMPROPER USE OR FAILURE TO FOLLOW INSTRUCTIONS CAN RESULT IN PRODUCT FAILURE OR INJURIES. FOR SAFE USE OF THIS PRODUCT YOU MUST READ AND FOLLOW ALL INSTRUCTIONS BEFORE USING.

INSTALLATION INSTRUCTIONS:

Use of a backflow preventer per local codes.
Install this device downstream of a backflow preventer. Backflow preventer sold separately. Use Chapin part number 6-9089.
WARNING: Line inlet water pressure should not exceed 60PSI. Pressure over 60PSI will result in damage to the tank and head. If line pressure exceeds 60PSI, install a pressure regulator on the inlet side of the injector.
For best results position the tank on a level surface.
Ensure all hose washers are in place and hand tightens connections firmly.
Connect the female swivel end to the water inlet. Connect your system hose to the male garden hose connection on the discharge side of the device.
Keep out of direct sunlight.
Screw on the ball valve to the threaded fitting on the bottom of the tank.

MAKING TUBING CONNECTIONS:

Tubing connections must be made between the injector manifold and the top of the clear tank lid. Prior to making final end connections, it is important that both the inlet and outlet tube pass thru the center of the black cap.

Two pieces of tubing are provided and can be cut to a shorter length if desired.
Connect the inlet tube from the injector manifold side port marked “1” to the IN port marked “1” on the clear tank lid.
Connect the outlet tube from the OUT port “2” on the clear tank lid to the bottom port marked “2” on the injector manifold.
Connections are made by sliding the tube over the barb fittings and securing the tubing using the clamps provided.

OPERATING INSTRUCTIONS:

Turn off the inlet water pressure.
Open the valve on the bottom of the clear tank to ensure it is empty. Close the valve.
Loosening the top cap will allow the unit to drain quicker.
For filling liquid fertilizer: Unscrew the cap and lid and slowly pour fertilizer product into the tank.
Re-install the cap and lid and tighten.
For filling granulated concentrate: Unscrew the cap and lid. Move it to the side allowing the inlet tube to remain in the tank. Fill halfway with the product. Re-install the cap and lid and tighten.
The injector is designed to work best with a water flow rate above 1 gallon per minute. At 1 GPM or above. the device is designed to feed the liquid fertilizer at a rate of approximately 1 ounce of fertilizer per gallon of water flowed.
For dilution rates less than 1 oz/gal, premix the product prior to filling the tank. Follow recommended dilution rates for the fertilizer being used.
Empty the tank and leave the bottom drain valve open when freezing conditions are present.
When watering without fertilizer, it is not necessary to disconnect this device.

WHEN USING GRANULAR PRODUCTS:

For best results when using granular products, dissolve the product in the water before filling the HydroFeed™ tank. Example: Mix 1 cup of granular fertilizer with 24 oz of water, or 1.25 cups for 32 oz. Stir to dissolve.
Fill tank.
Note : This is not the dilution ratio for application. The fertilizer is still a concentrated solution. Your HydroFeed™ fertilizer injector will automatically deliver 1 oz of concentrated fertilizer per 1 gallon of water. Always refer to the chemical manufacturer’s instructions for recommended application and coverage information.

SETTING	THE DEVICE WILL DELIVER
1	9-10 oz. /gal.
2	4-5 oz. /gal.
3	2-3 oz. / gal.
4	1-2 oz. / gal.

Performance will vary slightly with differences in downstream back pressures
