2.3 Stock Solution Location
The solenoids rely on gravity to deliver nutrient and pH adjuster
into the nutrient tank. This means the stock solution tanks must be
above the nutrient mixing tank.
Align stock tanks above nutrient tank.
2.4 Solenoid System Set-up
The solenoids dose nutrient and pH adjuster to your tank at defined
intervals. These intervals are set in the on times and off times
found in the mode menu. The instructions for this are on page 23
and 24.
1. Drill a 18mm (3/4”) diameter hole near the bottom of each stock
tank. Ensure tank is empty before drilling. Remove drilling
residue (swarf) from the inside of the stock tank as this can clog
the solenoids.
2. Insert sealing grommet. Seal must be tight, a firm push
is required. See figure 1.
3. Insert the solenoids into the grommets.
4. Label tanks Nutrient A, Nutrient B and pH.
5. Secure breather tube to the top of the stock tank to avoid
spillage.
6. Place the feed hoses from the solenoids to the main tank.
To ensure even dosing of Nutrient A & B the tubes have to be
the same length. Nutrient A & B must drop into the tank, do
not mix before entering the water.
7. Test stock tanks for water tightness. Fill with nutrient or pH
adjust solution.
To prevent acid
damage on your
piping & fi ttings,
make sure you dilute
your acid solution to
5% or less.

Breather tube must be
higher than the nutrient
level inside the stock
solution tanks.
