Sump Flow Control is an alternate method of managing low a water
velocity by using the sump pump rather than the primary water pump
for water circulation. Much like the Manual Mode for the primary pump,
using the sump pump to control the water velocity will also allow for fl ow
speeds between 0.15 m/s and 0.2 m/s. However, using the sump pump to
manage the water velocity requires the user to set the valves on the EFA
prior to engaging the sump pump.
To use the sump pump to manage the water speed do the following:
1. Fully close the Flow Restriction valve
