4. Liquid level in the bowl must be kept below the level indicator line as marked. It is recommended
practice to drain a unit equipped with the manual drain at least once during an eight (8) hour pe-
riod. To do so, rotate the drain knob to the left one or two turns.*
5. Before returning unit to service, insure that all seals have been properly reinstalled or replaced and
components requiring torque have been properly tightened. Also, insure that bowl seal O-ring
and bowl have been installed properly and that the bowl is in the locked position and the drain is
properly secured.
Note: In the event the drain knob is over-rotated, it may become disengaged from the drain stem. In
such a case, pull down on both the knob and the stem while rotating clockwise to re-engage. (view
