Accessories and additional parts fitted to the DRYVAC must fulfil the require-
ments of the ATEX Directive 2014/34/EU regarding the equipment group and
category and they must be applicable for use in explosive atmospheres of
the respective gas group and temperature class.
The mandatory safety instruments specified in this manual must be used and
must not be replaced with alternatives from other manufacturers without con-
sultation with Leybold.
DRYVAC pumps must only be used on processes if their materials resist the
mechanical and/or chemical influences and corrosion, under the respective
operating conditions, so that the explosion protection is always maintained.
Do not clean the pump by means of dry cloths in order to avoid electrostatic
charge on non-dissipative materials. Processes generating intensive charge
must not be operated close to the DRYVAC.
Means for preventing backflow of the pumped media must be used if back-
flow can result in process hazards.
Opening the DRYVAC is only permitted with the pump switched off, isolated
from the electrical supply and in the absence of explosive atmosphere.
