STEP 12 - Attach the Electronic Flow Controller (Model K28, or older
Crayfish
)
If you purchased the Digital Flow Controller (Model K500, or older
Alix
), see the separate
instruction sheet. Attach the flow controller to the downstream end of the box using the hook
(note that some older controllers have a Velcro connection)
. See Figure 19
.
Figure 19. Attach the controller to the downstream end of the box.
Connect the pump to the controller using the gray, blue, and orange connectors (note there is
one red tab that is not a connector). Then, connect the controller to the power supply using the
black and red connectors. See Figure 20.
Note that older models of the pump and controller
have different connectors. The older models will not work with the new models as shown here.
Simply match up the colors on the connectors.
Figure 20. The pump, at left, connects to the flow controller,
middle. The flow controller, right, connects to the power supply.
The color-coded connectors on each component will match up.
