The process used must be monitored on a regular basis by the su-
pervisor to check foaming levels.
To avoid the risk of damage to the machine and any accessories
used with it caused by chemical agents, soiling and any reaction
between the two please read the notes in "Chemical processes and
technology".
Even when a process chemical, e.g. cleaning agent, is recommen-
ded, W&H or the manufacturer takes no responsibility for the effect of
such chemicals on the load items.
Please note that changes in product formulation, storage conditions,
etc. which are not announced by manufacturers of process chemicals
may impair the quality of cleaning results.
When using process chemicals, always consult the instructions is-
sued by individual manufacturers. Process chemicals must only be
used for the purpose they are designed for by the manufacturer to
avoid any material damage or the occurrence of very strong chemical
reactions (e.g. oxyhydrogen explosion).
Always follow the relevant manufacturer's instructions on storage
and disposal of chemical agents.
Particles ≥ 0.8 mm are removed by the filters in the wash cabinet.
Smaller particles may find their way into the circulation system. For
this reason, processing of loads with narrow openings requires addi-
tional filtering of the wash water.
In critical applications where very stringent requirements have to
be met, it is strongly recommended that all the relevant factors for the
process, such as cleaning agents, water quality, etc., are discussed
with W&H.
The mobile units, baskets, modules and inserts that hold the load
must be used only as intended.
Hollow items must be thoroughly cleaned, internally and externally.
Secure small and light items with cover nets or place in a mesh
tray for small items, so that they do not block the spray arms.
Empty any containers or utensils before loading them.
The amount of residual solvents and acids on items going into the
cabinet should be minimal.
There should be no more than a trace of any solvents with a flash
point of below 21 °C.
Chlorous solutions, in particular hydrochloric acid, must not be
placed in the cabinet.
Ensure that solutions or steam containing chlorides or hydrochloric
acid do not come into contact with the stainless steel outer casing of
the machine in order to avoid any damage through corrosion.
