Changing the TSL
5. Fill reservoir 3/4 full with TSL (6).
Part No. 206995 Throat Seal Liquid (TSL) carries isocy-
anate from the pump rod into the reservoir. After some
time the TSL will thicken and darken, and must be
replaced. Thick, dirty TSL will not pump through the
lines and will harden in the pump wet-cup.
6. Run pump. Each time pump A rod reaches bottom of
stroke, check that some TSL is pumped from reser-
voir (1), through wet-cup (10), and back to reservoir.
How long TSL lasts depends on which chemicals are
used, how much is used, what pressure, and condition
of the pump seal and rod. Check the condition of the
TSL every week, minimum, and change when needed.

3. Remove reservoir cap. Empty reservoir (1). Clean
any residue.
Part No. 246928 includes reservoir, tubing, and fittings
necessary to modify the Reactor to use the wet-cup
flush design. Order the pump separately, see below.
Refer to displacement pump manual 309577 for further
information.
4. Clean screen (V) of inlet check valve (1c). If check
valves are not sealing and dirty TSL is getting into
the wet-cup, replace the check valves (1b, 1c).
