Check the condition of the TSL fluid daily.
Change the TSL fluid if it becomes a gel, its color
darkens, or it becomes diluted with isocyanate.
Gel formation is due to moisture absorption by
the TSL fluid. The interval between changes
depends on the environment in which the
equipment is operating. The TSL fluid system
minimizes exposure to moisture, but some
contamination is still possible.
TSL fluid discoloration is due to continual
seepage of small amounts of isocyanate past
the pump packings during operation. If the
packings are operating properly, TSL fluid
replacement due to discoloration should not be
necessary more often than every 3 or 4 weeks.

2. Lift the TSL fluid reservoir (R) out of the
bracket and remove the reservoir from the
cap. Hold the cap over a suitable waste
container and flush contaminated fluid
out of the lines by placing the strainer in
the new fluid and dispense contaminated
fluid through the return line into the waste
container.
3. Manually cycle the peristaltic pump (PP) in
the diagnostic screen until all contaminated
TSL fluid is removed from the system.
4. Drain the reservoir and flush it with clean
TSL fluid or replace it with a new reservoir.
