Greentrees Hydroponics MULTI FLOW HYDROPONIC SYSTEM Instructions Manual page 4

Use the screw to hold the Fill/Drain Tube Mount to the top of the
reservoir. There is a small hole for the screw next to the large hole.
Make sure the tube mount hangs over the reservoir hole so the siphon
breaks are clear and unobstructed.
Insert the two ½" Elbows into the grommets at the top near the
FILL marking.
Connect the the Fill/Drain Tube Set to the elbows. Looking at it
from the outside, the Fill tube goes on the left and the Drain on the right.
Cut a ten inch section of the ½" tubing and connect it to the other
pump. Connect the other end to the drain elbow inside the controller.
Tie a knot in the Drain Pump power cord so the cord stays out of
the Water Level Switches.
The two upper Water Level Switches are on an adjustable mount so
the Controller can be used with different size pots. It should be 11-1/2"
from the base of the controller to the top of the Water Level Switch
Mount if you're using the Multi Flow Pots. Test your fill depth
carefully. It should fill the lower pot ½" from the top. Remove the upper
pot to test. Do not over-tighten the thumbscrew.
