Clean Retorts
Clean the retort walls daily with a lint-free cloth moistened with 70% alcohol.
Figure 64. Retort interior with: air hole (1), level sensors (2), stirrer (3), and filter (4)

Ensure the air hole is unobstructed.

Carefully wipe the liquid level sensors. If you cannot remove stains with the alcohol solution,
use a lint-free cloth moistened with 6% acetic acid or CLR ® , then wipe again with ethanol. If
still not clean, do a retort acid clean (see 7.5 Retort Acid Clean).

Inspect the filter. If soiled, lift it out and clean with 70% alcohol.

Inspect the stirrer. If dirty, lift it out and clean with 70% alcohol. If damaged or showing signs
of rust, contact your service representative for replacement.
To replace the stirrer, hold it as indicated in Figure 65 and carefully allow it to slide onto the
spindle in the bottom of the retort.
CAUTION
Take care not to drop anything into the opening when the filter is removed. Foreign material in
the line could stop valves operating properly.

WARNING
The magnetic coupling will pull the stirrer towards the bottom of the retort. To avoid pinching
your fingers, do not allow them to be trapped between the stirrer and the bottom of the retort.
