close the flow control valve and switch off the pump. It is suggested that the channel is
left standing in this condition for at least one hour to allow any leaks to become visible.
Check the channel and pipework for leaks and tighten the appropriate fittings as
necessary.
28. The accuracy of the zero setting on the slope indicator can be checked as follows: Attach
a hook and point gauge to a carrier and install a point in the end of the rod. Locate the
carrier on the top of the channel sides and position it at one end of the channel. Adjust the
gauge to indicate the height of the water then transfer the gauge to the opposite end of the
channel. The water level will be the same if the channel is level. Adjust the handwheel on
the jack, if necessary, to obtain the same reading at both ends of the channel. The position
of the scale can then be adjusted to read zero against the pointer.
29. Remove the stop logs one at a time and allow the channel to drain. Ensure that the flow
control valve is closed and the pump is switched off.
Note: After use always allow the water to drain down into the sump tank of the F1-10.
The flow control valve can be opened to allow water to drain from the pipework
to the sump via the pump.
