Page 11: Transport And Storage
P2.x Atex 3 Transport and storage Only transport the product inside the original packaging or a suitable alternative. The equipment must be protected from moisture and heat when not in use. They must be stored in a covered, dry and dust-free room at a temperature between -20 °C to +40 °C (-4 °F to 104 °F). -
Page 12: Installation And Connection
P2.x Atex 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. -
Page 13: Outdoor Installation

Page 14: Special Condition Moist Sample Gas
P2.x Atex 4.3 Special condition moist sample gas Applications where the sample gas is still moist may result in condensate forming in line and the pump body. In these events the pump head must be suspended (pump body facing down). If the pump was not ordered this way, it can easily be converted on site. -
Page 15: Connecting The Gas Tubes
P2.x Atex 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. -
Page 16: Electrical Connections
P2.x Atex 4.4.1.2 Monitoring measures when conveying flammable and/or toxic gasses Conveying flammable and/or toxic gasses further requires continuous monitoring of the sample gas pump during operation. This can be done as follows (1) or (2). Flow rate monitor before the pump’s gas inlet and after the gas outlet. A sudden reduction of the suction volume / flow volume ahead of the pump and consistent or suddenly increased flow volume after the pump indicates a defective bellow (the pump can convey ambient air suctioned in due to the tear). - Page 17 P2.x Atex Verify the pump motor has the correct voltage and frequency: Voltage tolerance ±5 %, frequency tolerance ±2 % - from rated value. Properly connect the sample gas pump per the respective wiring diagram (see below). If the wiring diagram inside the cover of the terminal box is different, observe that instead.
