Installation of the MC740R Nutrient Controller with adjustable pump:

Fix the MC311 monitor to the wall near the nutrient tank with an adhesive velcro or with 4 screws.
Connect the pump coupling base (black and white color) to the power supply.
Dip the tip of the electrode (up to about 2.5 cm) in the nutrient mixture. Hold the electrode with the help of the polyexpan float.
Turn on the monitor by pressing the ON / OFF button.
Select the set point, with the help of the graduated wheel.

Installation of the MP815 dosing pump:

Connect the soft tube to the pump (suction tube - left) and the filter (white) to the other end of the tube (to prevent the suction of solids).
Connect the rigid tube to the pump (impulsion tube - right) - Optional: a black thread to connect to a pipe.
Fix the pump to the wall or directly to the Liquid FERTILIZER bottle, in a vertical position in the immediate vicinity of the nutrient tank.
Connect the electrical socket of the dosing pump to the thief, and connect the thief to the mating socket (black and white) of the MC311 controller.

The MP815 peristaltic pump is a 2.2L / h pump adjustable from 0% to 100%; Regulation is manual (roulette)

IMPORTANT :

It is advisable to set the pump at its minimum flow rate for a smooth adjustment of the nutrient level.

And if your tank is small and your fertilizers are highly concentrated, it is advisable to dilute the liquid fertilizer with water in a carafe. Example: For a 100 liter tank, dilute 100 cl of FERTILIZER in a 5 liter jug of water. This data can be adjusted according to the volume of your tank, the concentration of your fertilizer corrector, and the strength of your recirculation pump or air diffuser stone.

VERY IMPORTANT: For a homogeneous and immediate mixture of the liquid fertilizer to your irrigation water tank, install a powerful recirculation pump and / or an air diffuser stone at the bottom of your tank
