2. Safety
The pumps have Protection Class 00, and so offer no
protection against contact or foreign bodies. It is therefore
essential to provide protection for persons against contact
with live parts (e.g. electrical connections, motor windings),
and moving parts (e.g. fan). Protection against the entry of
foreign bodies must also be provided.
The pump has no protection against water. In this case too, as far
as is relevant, measures to protect the pump must be taken before
putting it into service.
Note that the pumps may only be used for their intended purpose.
The pumps must not be used in areas where there is a danger of
explosion.
For vacuum pumps, the exhaust gases must be safely disposed.
Components connected to the pump must be designed to
withstand the pneumatic performance of the pump.
Take care that safety regulations are observed when connecting
the pump to the electricity supply.
For pumps with thermal switch: When the operation of the pump is
interrupted by the thermal switch, the pump will re-start
automatically after cooling down. Take all care necessary to
prevent this leading to a dangerous situation.
Specific safety instructions for the media being handled must be
observed.
When using hot media, the pneumatic pump suction and pressure
lines heat up, as does the pump head. Do not touch these parts;
they could burn you.
Use only original KNF spare parts.
For the purposes of the Machinery Directive 2006/42/EC, pumps
are “partly completed machinery,” and are therefore to be regarded
as not ready for use. Partly completed machinery may not be
commissioned until such time as it has been determined that the
machine in which the partly completed machinery is to be
assembled is in conformity with the provisions of the Machinery
Directive 2006/42/EC.
The following essential requirements of
Annex I of Directive 2006/42/EC (general principles) are applied
and observed:
General Principles No. 1
No. 1.1.3 / 1.1.3 /1.3.1 / 1.3.4 / 1.4.1 / 1.5.1 / 1.5.2 / 1.5.8 /
1.5.9 / 1.7.4 / 1.7.4.1 / 1.7.4.3
As these partly completed machinery are OEM-models the power
supplies and the equipment for disconnecting and switching-off the
partly completed machinery respectively have to be considered
when mounting as well as over-current and overload protective
gear.
