9.0 Set up outlet dosing tube
Insert the remaining dosing tube with
connector into the RIGHT peristaltic pump
tube. This is the ‘outlet dosing tube’.
Cut the outlet dosing tube so that the tube
sits above the maximum solution level of the
reservoir/tank. The pH stock solution must
drip into the nutrient reservoir/tank.
Note: If the outlet dosing tube is immersed
in reservoir/tank solution, it could create
a syphon. This would cause the pH stock
solution to overfl ow.
8.0 Set up inlet dosing tube
To straighten tube:
Bend tube in the opposite direction and
straighten by running through closed fi ngers.
Insert one end of the dosing tube with
connector into the LEFT peristaltic pump tube.
This is the ‘inlet dosing tube’.
Ensure the inlet dosing tube will reach the
bottom of the pH stock solution container.
There also needs to be enough tube left for the
outlet dosing tube to go into the reservoir/tank.
Cut the inlet dosing tube to the desired length.
Use inlet tube cap supplied to place on
Bluelab Up or Down 500ml or 1 Liter bottles.
This will hold the tube in position. Insert the
inlet dosing tube through the hole in the cap
and pierce the induction seal on the bottle.
