1 General Information

These additional operating instructions are applicable only in conjunction with the Installation and
Operating Instructions. They contain supplementary information on the specific requirements for
use of the appliances, certified and approved by the recognised testing and approval authority "FM
Approvals".
1.1 Uses
These submersible pumps are suitable for use in gas-, vapours- and mist atmospheres, according
to the markings on the type plate.

1.2 Product data

1.2.1 Construction model
The explosion protection model provided falls into the fire protection category "flameproof enclo-
sure". The following norms are upheld in particular:
FMC 3600, 3615, 3615.80
ANSI/UL - 1004
Identification symbol:
These submersible pumps are approved for operating in potentially explosive areas
and may be operated where electrical devices with the protection class "explosion-
proof" are required.

1.2.2 Operation parameters
The electrical parameters for the operation of the submersible pumps must be taken from the type
plate. They are electrical values to be observed for new hydraulics when pumping clear water and
which can be operated to S1 as a maximum. The thermal protective switch (WSK) will switch the pump
unit off should these values be exceeded. To prevent misuse of this function as a switch, ensure the
submersible pump is operated below the switch-off point at all times. We recommend that the oper-
ating current should be a maximum of 90% of the nominal current (for nominal voltage decrease by
the corresponding amount for high voltage and under voltage). We also advise the operator to ensure
when commissioning the pump and at regular intervals thereafter that the pump is not overloaded.
The motor is sealed against the pump chamber using 2 mechanical seals. In order to ensure the pump
never runs dry and no unauthorised high temperatures are able to arise at the sliding surfaces, the
separating chamber between the mechanical seals is filled with medical white oil.
The liquid is poured in when the pump is first assembled and must be topped up after all assembly and
repair work.
