P2.3C P2.4C DANGER Potentially explosive atmosphere Explosion hazard if used in hazardous areas. The device is not suitable for operation in hazardous areas with potentially explosive at- mospheres. DANGER Explosion hazard Life and explosion risk may result from gas leakage due to improper use.
P2.3C P2.4C 3 Transport and storage The products should be transported only in its original packaging or a suitable replacement. When not in use, protect the equipment against moisture and heat. Keep it in a covered, dry and dust-free room at a temperat- ure of -20 °C to +40 °C.
P2.3C P2.4C 4 Installation and connection Check the equipment for damage before installation. Among other things, this could be a damaged housing, supply cables, etc.. Never use equipment with obvious damage. CAUTION Use appropriate tools According to DIN EN 1127-1, the operator is responsible to select and use appropriate tools.
P2.3C During the installation of the P2.3C sample gas pump onto mounting plates, use the supplied mounting bracket and exclusively the supplied rubber-metal buffer. Operation without the rubber-metal buffer is forbidden. They must also be used if the pump is installed on an existing supporting structure.
P2.3C P2.4C 4.3.1 Alteration of hanging pump bodies CAUTION Damage to the device Especially with pump head pointing down, make sure that no dust or small parts can in- trude the pump through the ventilations slot. Nevertheless, the slot must not be covered directly.
P2.3C P2.4C 4.4 Connecting the gas tubes The pumps are delivered with customized gas connections. Please compare the part-no. on the type plate with the part-no. ex- plained in chapter "Introduction". Avoid mixed installations, that is connecting metal tubes to plastic bodies. If this is unavoidable for sporadic applications, screw the metal fitting with utmost care and without any use of force to the PTFE pump body.

CAUTION Wrong mains voltage Wrong mains voltage may damage the device.
P2.3C P2.4C 5 Operation and control NOTICE The device must not be operated beyond its specifications. DANGER Danger of explosions, danger of poisoning from poisonous corrosive gases During maintenance work, depending on the medium used, explosive and/or poisonous corrosive gases could escape, and this could lead to a danger of explosion or could be hazardous to health.
P2.3C P2.4C 5.1 Switching on the sample gas pump Before switching on the device, ensure that: – the hose and electrical connections are undamaged and correctly installed, – no parts of the sample gas pump have been dismantled (e.g. cover), –...
P2.3C P2.4C 6 Maintenance Maintenance work on the device must be carried out in a cooled state. During maintenance, remember: – The equipment must be maintained by a professional familiar with the safety requirements and risks. – Only perform maintenance work described in these operating and installation instructions.
P2.3C P2.4C CAUTION Hot surface Burning hazard According to the product type and operation conditions, the temperature of the housing may exceed 50 °C during operation. Depending on the conditions at the installation site it may be necessary to provide these areas with appropriate warning signs.
P2.3C P2.4C Since a crack in the bellow allows the ambient atmosphere to be sucked in and the sample gas pump continues to generate pressure, the bellow on the sample gas pump must be inspected regularly. This is done by connecting a suitable shut-off unit and a suitable vacuum pressure gauge ahead of the sample gas input (see il- lustration).
