Install the pumps and tanks
The control unit has seven numbered pump outlets plus one marked circ pump. Which pump goes where:
| Purpose | Pump | Where it sits |
|---|---|---|
| Dose nutrients, pH adjusters or additives | Dosing pump (peristaltic) | Outside the liquid, with its intake hose in the supply bottle |
| Refill with fresh water | Volume pump (centrifugal) | On the bottom of the fresh-water tank |
| Drain the reservoir | Volume pump (centrifugal) | On the bottom of the reservoir |
| Circulate the nutrient solution | Volume pump (centrifugal), on the circ pump outlet | In the reservoir |
- Mount each pump with its magnets or suction cups. See Mounting.
- Route the hoses so that nothing can siphon. A hose end that lies below the liquid level of the tank it draws from keeps flowing after the pump has stopped. Read Avoiding siphoning before you cut any hose.
- Connect the pumps to the outlets and write down which outlet each pump is on. You pick pumps by outlet number in the app.
