the drain are clean.
3. Install the Waste Drain Assembly and Gasket from below the sink.
4. Install the Sink Flange thru the sink drain opening and screw it into the Waste Drain
Assembly below.
5. Before tightening, position the waste drain Handle to the desired location. Tighten
the Sink Flange securely with a Sink Flange Tool* or similar.

Parts kit B-39K* is available for all servicable seals in Waste Drain models B-3940 Series
thru B-3970 Series. Most seal service and maintenance can be conducted without
removal of the waste drain from the sink or plumbing system. A typical maintenance
procedure is as follows:
1. Remove the Snap-in Strainer to allow access to the plunger.
2. Loosen and unscrew the Handle Nut and remove the Handle Assembly. Handle
Assembly seals can be serviced at this point.
3. Lift and remove the Plunger. The plunger O-Ring can be serviced at this point.
4. Re-assemble in reverse order. Check for leaks.
* B-39K is available through T&S (see last page).
