Immediately after completing work, all safety and protective devices must be put back
in position and/or recommissioned.
2.5
Unauthorised modification and
manufacture of spare parts
Unauthorised modification and manufacture of spare parts will impair the safety of the
product/personnel and void the manufacturer’s declarations regarding safety.
ƒ
Only carry out modifications to the product following consultation with the manu-
facturer.
ƒ
Only use original spare parts and accessories authorised by the manufacturer.
The use of other parts will absolve the manufacturer of liability for any con-
sequences arising therefrom.
2.6
Improper use
Operational reliability is not ensured except in conjunction with intended use as out-
lined in chapter "Intended use" in these supplementary installation and operating in-
structions.
The limit values must on no account fall below or exceed those values specified in the
catalogue/data sheet.
2.7
Residual hazards
The following residual hazards could be caused by the pumps:
The pumps and equipment parts, such as the installation flange and the
sealing (mechanical seal, flat gasket including the pipework), can be sub-
ject to pressure or high temperatures resulting from the fluids and gases.
Even when all necessary precautionary safety measures have been imple-
mented, there still exists a residual danger caused by leakiness or mechanical
damage on the pump body. Gases, vapours or fluids could escape unnoticed
at gaskets or screwed connections.
An uncontrolled chemical reaction could take place in the product area
when the pump has failed due to motor or coupling malfunction.
An electrostatic charging of the circulating fluid and thus the danger of
ignition is possible as a result of the pump operation, as is the case with all
closed circuit circulation processes involving flammable liquids.
• Take appropriate safety precautions (see chapter "Earthing" and chapter
"Coupling guard").

Intended use
Purpose
Potentially explosive atmospheres in Categories 2 and 3, Atmosphere G, are subject to
the scope of validity of Directive 2014/34/EU. No pumps may be utilised in this area ex-
cept those whose designs have been approved for the specific utilisation purpose in-
tended.
Examination Certificates prescribed pursuant to Directive 2014/34/EU which relate to
the relevant DIN EN 60079 standards series must be available for the drive motor and
the electrical equipment. These components must also be appropriately labelled.
The glanded pumps in the following series are intended for use as circulators in building
services:
