CLEANING
After every dispensing process involving aggressive or self-curing substances, a cleaning pro-
cedure is recommended. It should involve the valve and all other surfaces in contact with
the fluid. Different methods of cleaning are described in the following chapter. The proper
choice depends on the degree of contamination and the dispense medium used.
8.1
Preliminary Notes
IMPORTANT NOTE! (Prepare cleaning in advance)
It is recommended to prepare the cleaning procedure in advance.
Do not drop the device or its subcomponents.
CAUTION! (Liquid spurts possible)
Residual liquids may spurt when handling components during the cleaning process. There-
fore protective clothes are recommended, like
•
Safety goggles
•
Overall
(chemical resistant)
•
Gloves
(chemical resistant)
•
Surgical mask
Remember that the surface of the valve is sensitive to abrasion, so do not use wire brushes
and other inappropriate tools. A specially developed cleaning tool kit
(CTK)
is available upon
request
(order code 1010320)
, which is of particular interest for all surfaces in direct contact
with the fluid.
WARNING! (Potential chemical reactions)
The dispensed medium and the cleaning agent must be compatible to each other. Otherwise
they might cause unwanted chemical reactions, toxic vapor, increase of temperature etc.
Consult the manufacturer in case of doubt.
Before introducing aggressive purifying agents or solvents to the system, verify com-
patibility with the material of all adjacent parts. Refer to the following list
(chapter
8.2)
or consult the manufacturer in case of doubt.
CAUTION! (Keep actuator clean)
No liquid may penetrate into the actuator
(e.g. through the plug);
otherwise the
whole element could be damaged.
