Congratulations on your purchase of one of Tefen's high quality products.
To get the best results from the MixRite TF-5 Proportioning Dosing Injector it is important to spend
a few minutes reading carefully the explanations and recommendations in this user's manual.
Operating principle
The proportioning dosing injector is fitted on the water line. The flow of water passing through the
injector activates it and causes the pumping of liquid fertilizer (or other additive) and inject it in a
relative quantity into the water line.
The MixRite TF 5 technical working range:
The flow rate of water passing through the injector is between 0.2 and 5 m³/Hr. (0.88-22 GPM).
The water pressure is between 1 and 8 bar (14.7 and 120 PSI).
The water and air temperatures are not less than 4°C and not more than 40°C (39°F - 104°F).
Head loss: Low flow 0.1 Bar – High flow 0.8 Bar.
Max deviation injection rate +/- 10%.
Before using, an initial calibration should be done, in order to assure accurate match with the
injector printed scale.
The flow rate of the fertilizer and chemicals can be adjusted relative to the flow rate of the water in
the range of:
0.1% to 1%
0.2% to 2%
0.5% to 5%
