12
These installation and operating instructions contain all the
12
information required for starting up and handling the DMH 25X

The DMH 25X pump is suitable for liquid, non-abrasive and
14
non-flammable media strictly in accordance with the instructions
14
in this manual.
18
22
Explosion-proof pumps are identified from the pump
22
and motor nameplates. An EC declaration of
22
conformity is provided in accordance with the EC
Note
directive 2014/34/EU, the so-called ATEX directive.
22
This declaration of conformity replaces the
22
declaration of conformity in this manual.
22
22
Warning
22
To operate a pump which has been identified as an
23
explosion-proof pump for the dosing of inflammable
24
media or for operation in potentially explosive
25
operating sites in accordance with the EC directive
26
2014/34/EU, refer to the enclosed manual
26
"ATEX-approved pumps" in addition to this manual.
27
Warning
27
Other applications or the operation of pumps in
27
ambient and operating conditions, which are not
27
approved, are considered improper and are not
27
permitted. Grundfos accepts no liability for any
28
damage resulting from incorrect use.

2. Safety
This manual contains general instructions that must be observed
30
during installation, operation and maintenance of the pump. This
31
manual must therefore be read by the installation engineer and
31
the relevant qualified personnel/operators prior to installation and
31
start-up, and must be available at the installation location of the
pump at all times.
32
It is not only the general safety instructions given in this "Safety"
32
section that must be observed, but all special safety instructions
32
given in the other sections.
