Comply with all applicable and relevant safety requirements (regulations and
guidelines). Implement the required actions and adopt suitable safety meas-
ures.
Ambient conditions
• Adopt suitable measures in case of differences from recommended conditions,
e.g., using the equipment outdoors, installation in higher altitudes, conductive
pollution or external condensation on the pump.
To the best of our knowledge the equipment is in compliance with the requirements
of the applicable EC-directives and harmonized standards (see ”Declaration of Con-
formity”) with regard to design, type and model. Directive EN 61010-1 gives in detail
the conditions under which the equipment can be operated safely (see also IP de-
gree of protection, „Technical data“).
Operating conditions
➨ These pumps are not approved for operation in potentially explosive atmos-
pheres. Do not operate the pumps in potentially explosive atmospheres.
➨
Pumps without the ” ` ” mark on the rating plate are not approved for the
pumping of potentially explosive atmospheres. Do not pump potentially ex-
plosive atmospheres with those pumps.
➨ Pumps bearing the ” ` ” mark on their rating plates are approved for the
pumping of potentially explosive atmospheres according to their classifica-
tion II 3G IIC T3 X according to ATEX, but they are not approved for operation
in potentially explosive atmospheres (see section „
`
Important information:
Equipment marking (ATEX)“) .
➨ The pumps are not suitable to pump any of the substances listed below.
Do not pump:
- unstable substances
- substances which react explosively under impact (mechanical stress)
without air
- substances which react explosively when being exposed to elevated
temperatures without air,
- substances subject to auto-ignition,
- substances which are inflammable without air
- explosive substances.
➨ The pumps are not approved for operation below ground. Do not operate the
pump below ground.
• Do not pump substances which may form deposits inside the pump. The pumps
are not suitable for pumping substances which may form deposits inside the
pump. Deposits and condensate in the pump may lead to increased tempera-
tures even to the point of exceeding the maximum permitted temperatures.
• Check the inlet and outlet of the pump, if there is a danger of forming depos-
its inside the pump, e.g., in the pump chambers (the pump chamber is the part
between diaphragm and head cover. See section „Replacing diaphragms and
valves“). Inspect the pump chambers regularly and clean if necessary.
