4.1.
RECEPTION OF THE PUMP
The received pump must be checked to ensure that it is adapted to the working
conditions of the classified area and the conditions of the order.
4.1.1.
Identification of the pump
The shipment should be checked in accordance with the instructions included in the manual. Also, the CE
ATEX mark affixed to the manufacturer's plate should be checked in order to verify that it matches the
requirements of the order.

4.2.
TRANSPORT AND STORAGE
If the pump is not for immediate use, then it must be moved twice a week in order to prevent the impeller
and mechanical seal from seizing up.
4.3.
LOCATION
Place the pump near a drain on the floor. Note that the handling of inflammable fluids can create an area
classified as Zone 0 in the drain area and therefore all the appropriate safety indications must be observed.
The motors used must be EC marked in accordance with Directive ATEX 2014/34/EU and with the
instructions of the manufacturer and the applicable national and local regulations.
When pumping inflammable or explosive liquids, a proper connection must be
used. Connect the parts of the assembly with the earth connections in order to
reduce the risk of static electricity.
Depending on the fluid to be pumped, high temperatures may be reached inside and around the pump:
Note that the surface temperature of the pump in normal operating conditions is
determined by the fluid it pumps. Therefore, for fluid temperatures above 108ºC,
the T4 protection level will no longer be valid.
Air must be properly recirculated in order to cool the pump motor. Make sure
there is no other equipment or surfaces near the motor that may radiate
additional heat or affect the cooling of the motor. See the motor instructions
manual.
4.4.
PIPES
Before starting up the pump, make sure that the suction and discharge valves of
the pump are open.
