Attach the draining valve with hose to Frame II and close the draining valve.
Before drilling through the main pipe, test that the valve can be closed: release the shaft’s locking
mechanism by pulling the spring loaded part # 400012 (see page 6) and slide out the shaft until it
mechanically stops at the outermost position. Close and open the hot tapping valve to verify it is working

Select a locking position that corresponds to the size of the hot tapping valve and lock the shaft to the
selected position (three alternatives —> see page 6).
