7GA01212_002_C1 - 04/2017 - © Leybold
When shipping the contaminated pump for servicing, please also state
the type of hazard. For this you must use a form which we have pre-
pared for you.
7 When cleaning a system in which a TRIVAC pump has been integrat-
ed, all parts in contact with the medium need to be compatible with
the cleaning agent so as to prevent a chemical reaction. Residues of
the cleaning agent within the pump must be avoided.
8 Contaminated parts can be detrimental to health and environment.
Before beginning with any work, first find out whether any parts are
contaminated. Adhere to the relevant regulations and take the neces-
sary precautions when handling contaminated parts.
0.5 Danger of ignition
1 For the purpose of conforming utilisation of the vacuum pump in
explosion hazard areas, Directive 1999/92/EC and additional regula-
tions must be observed.
This directive provides for obligations of employers for the safety and
health protection of workers potentially at risk from explosive atmos-
pheres. Hereafter the operating company is under the commitment to
draw up an explosion protection document, with classifying ex-hazard
areas into zones.
The utilisation of the pump must be verified against corresponding
equipment-categories, temperature classifications and gas groups.
(cf. Section “Classification and Marking of the Pump” below).
2 The pump is not suited for pumping of mixtures of oxygen exceeding
the concentration as found in the atmosphere. Furthermore the
TRIVAC D 16 B Ex is not suited for pumping of acetylene, carbon
disulphide or other chemically instable gases.
3 Any constructional alterations or modifications whatsoever compared
to the delivery status of this pump or the monitoring systems and
devices are prohibited and will void the EC Declaration of Conformity.
With any service work (assembling, electrical installation, repair, open-
ing the housing) it has to be ensured that
■there is no explosion hazardous atmosphere,
■the pump is disconnected from the mains supply (lock- / tag out),
■the pump cannot run inadvertently.
4 Installation, usage of, and maintenance works on this pump must only
be conducted by trained and duly authorised personnel.
Special attention must be paid to:
■all technical data and information regarding the conforming utilisation
(commissioning, environmental and operational conditions) contained
in the operating instructions, the nameplate, and collateral product
documentation.
5 The attached electrical apparatus must be installed explosion-proof
and connected IAW the corresponding type of protection:
■for the motor: Increased Safety ‘e’;
■for the pressure sensor: Intrinsic Safety ‘ia’ (only for connections to
certified intrinsically-safe circuits);
■for the temperature sensor: PT100 passive sensor (only for connec-
tions to certified intrinsically-safe circuits).
