Remove all packing material, remove the product from its packing-box, remove the protective covers from the inlet and outlet ports and keep them, inspect the equipment. If the equipment is damaged, notify the supplier and the carrier in writing within three days; state the item number of the product together with the order number and the supplier's invoice number. Retain all packing material for inspection. If the equipment is not used immediately, replace the protective covers. Store the equipment in suitable conditions. • Read and obey this manual before installing or operating the equipment....

• If the equipment is brought from cold environment into a room for operation, allow the equipment to warm Q up (pay attention to water condensation on cold surfaces). Q- • Make sure ventilation is adequate if pump is installed in a housing or if ambient temperature is elevated. ^ Obey all relevant safety requirements (regulations and guidelines) and adopt suitable safety measures. ¡_¡. • Provide a firm level platform for the equipment and check that the system to be evacuated is mechanically Q stable and that all fittings are secure. —' Note: Flexible elements tend to shrink when evacuated....

Pumps with dual-voltage motor: The motor Is shut down by a thermal cutout In the winding. Q_ Manual reset is necessary. Switch off the pump or isolate the equipment from mains. Wait approx. five minutes before restarting the pump. Pumps with 24 V DC voltage: The motor is protected by a temperature sensor at the circuit board (current limitation if the temperature at the circuit board is higher than 70°C). Avoid high heat supply (e. g. due to hot process gases). Ensure sufficient air admittance if pump is installed in a housing. Due to the residual leak rate of the equipment, there may be an exchange...

Note: A suitably trained or qualified technician must carry out the following procedures. Ensure that the motor is correctly configured for your electrical supply. If you operate the pump when the motor is not correctly configured for the electrical supply, you will damage the motor. Do not change the voltage selector switch while the pump is connected to the mains supply. Figure 5 - Adjust the supply voltage 1. Voltage selector switch 1. Selecting 115 covers a voltage supply range of 100 V to 120 V. 2. Selecting 230 covers a voltage supply range of 200 V to 240 V. Ensure that the voltage shown...

Figure 6 - Replacing the motor fuse (dual-voltage motor) 1. Carefully remove the fuse holder at the side of the pump (refer to Figure 1, item 5). 2. Replace the defective fuse with a 2.5 A type T and secure the fuse carrier back into its holder. The pump has been factory set to a constant pumping speed when connected to a 24 V DC (=/-10%) supply. The pump can also be controlled using an external analogue 0-10 V signal. Use a suitable connector mating half (not supplied) to connect the electrical supplies and your control equipment to the connector on the logic interface cable. When you make the...
