Maintenance

Changing the TSL

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.

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.

To change TSL:

1. Turn main power OFF

. Disconnect power

supply.

2.Relieve pressure, see Reactor operation manual.

3.Remove reservoir cap. Empty reservoir (1). Clean any residue.

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).

Maintenance

5.Fill reservoir 3/4 full with TSL (6).

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.
