INSTALLATION OF CONTROLLER:
Connect the supplied
240VAC/12VDC power adapter to the meter and to the main line.
Connect the connection base (black and white outlet) to the main line
.
Always remove the probe’s protective cap before taking any measurement. Make
sure that the meter has been calibrated before taking any measurements
Immerse the tip (2.5 cm) of the EC probe into the sample. (for example, it can
float with the help of a piece of polystyrol).
Turn the instrument on by pressing the ON/OFF button.
The nature of the setpoint can be selected by setting the switch to the
desired position (ABOVE or BELOW).
USE ALWAYS BELOW!
Allow the reading to stabilize and the meter will start continuous monitoring.
A blinking alarm will indicate when the measured EC value is higher or lower
than the selected setpoint, depending on user selection. When the alarm is
activated, it also activates the connection base and the auxiliary equipment
.
The setpoint can be selected by adjusting the central front knob to the
desired value. The selectable range is from 0.8 to 2.8 mS.
CALIBRATION
- Clean the probe with alcohol and let it dry (if more thorough cleaning is required, brush the metal pins with fine sandpa-per and then rinse with water).
- Open a sachet of suitable conductivity calibration solution and immerse the probe, making sure that metal pins are completely submerged. Use M10031 (1413 μS/cm).
- Turn the meter on by pressing the ON/OFF key.
- Wait until the reading stabilizes for temperature variations, and then adjust the EC calibration trimmer on the front panel with the supplied screwdriver until the display shows: “1.4” mS.
The calibration is now complete and the meter is ready for use. The instrument should be re-calibrated at least once a month, or when the probe is changed.
INSTALLATION OF THE MP810 1,5 L/H DOSING PUMP
Connect the rigid tube to the pump (aspiration – arrow upwards). Fix the white
filter on the other end of the tube, where the dis-solved pH reducing acid
will be drawn in – to prevent small objects from entering the pump.
Connect the soft tube to the pump (impulsion – arrow down-wards). The
injection fitting will be placed at the end of this tube only to inject into
the piping. (This fitting has a thread that links it to the piping.)
Mount the bracket in the wall in an upright position above the water container
(which contains a solution of EC reducing acid and water).
Place the pump in a vertical position (with the tubes below) on the wall,
above and centered with the “Mounting bracket“. Then go down the pump until it
is joined with the bracket.
Connect the pump to the MC311 EC controller (on the black and white outlet).
The pump will discharge 0,08 cL every 2 seconds when active.
Place the plug and B/W outlet far away from the water!
Before servicing (maintenance) on the pump (e.g. changing tube), please
disconnect the equipment.
It is suggested to dissolve 10 cL of Mono-nutrient in a 5L container of water.
Depending on the volume of your tank and the brand of your Mono-nutrient (and
whether it is more or less concentrated), this quantity can be increased
later. It is better to dissolve more than less. It is suggested to use an
airstone on the bottom of your tank. The pump can be attached directly to the
container of the solution.
IMPORTANT: For a smooth adjustment of the EC of your nutrient mix, it is
advisable to dilute each liquid nutrient with water in a jug. Example: For a
100-liter tank, dilute 500cl of nutrients in a 5-liter jug of water. This
quantity can be adjusted according to the volume of your tank, the
concentration of your nutrient, and the power of your recirculation pump or
air diffuser stone.
VERY IMPORTANT: Both dosing pumps work at the same time and inject the
same amount of fertilizer A and fertilizer B. If your fertilizer A + B is not
50%/50%, you will have to dilute your fertilizers proportionally. Example: For
a 40%/60% fertilizer A + B, put 4 caps of bottle A and fill it with water, and
on bottle B, put 6 caps of the fertilizer B and fill it with water (adjust the
quantity of fertilizer as necessary).
VERY IMPORTANT: To obtain an even mixture and an immediate dilution of
your fertilizers, install at the bottom of your tank a recirculation pump
and/or an air diffuser stone
