Use Operating parameters and conditions Requirements for transferred medium 2. Use 2.1. Proper use The pumps are exclusively intended for transferring gases and vapors. Owner's responsibility Only install and operate the pumps under the operating parameters and conditions described in Chapter 4, Technical data. Protect the compressors with a pressure relief device between the pressure side of the compressor and the first shut-off valve. Only complete pumps may be taken into service. Make sure that the installation location is dry and the pump is protected against rain, splash, hose and drip water. The gas-tightness of the connections between the application pipes and the pump (or the pump connection) must be checked regularly; with leaky connections, there is a danger that hazardous gases or vapours may escape from the pump system. Before using a medium, check whether the medium can be transferred danger-free in the specific application case. Before using a medium, check the compatibility of the materials of the pump head, diaphragm and valves with the medium. Only transfer gases which remain stable under the pressures and temperatures occurring in the pump. 2.2. Improper use The pumps may not be operated in an explosive atmosphere. The pumps are not suitable for transferring dusts. The pumps are not suitable for transferring liquids. Pumps designed to create either a vacuum or an overpressure must not be used for these two purposes simultaneously. An overpressure must not be applied to the suction side of the pump. Pumps with three-phase motor are not provided for the operation with frequency converter. Operating and Installation Instructions, english, KNF 120859-121488 08/13 3
Safety 3. Safety Note the safety precautions in chapters 6. Installation and connection, and 7. Operation. Personnel Working in a safetyconscious manner Handling dangerous media Handling combustible media Environmental protection EC Directives / Standards The pumps are built according to the generally recognized rules of technology and in accordance with the occupational safety and accident prevention regulations. Nevertheless, dangers can result during their use which lead to injuries to the user or others, or to damage to the pump or other property. Only use the pumps when they are in a good technical and proper working order, in accordance with their intended use, observing the safety advice within the Operating and Installation Instructions, at all times. Make sure that only trained and instructed personnel or specially trained personnel work on the pumps. This especially applies to assembly, connection and servicing work. Make sure that the personnel has read and understood the Operating and Installation Instructions, and in particular the "Safety" chapter. Observe the accident prevention and safety regulations when performing any work on the pump and during operation. The pump heads heat up during operation avoid contact with them. When transferring dangerous media, observe the safety regulations when handling these media. Be aware that the pumps are not designed to be explosion-proof. Make sure the temperature of the medium is always sufficiently below the ignition temperature of the medium, to avoid ignition or explosion. This also applies for unusual operational situations. Note that the temperature of the medium increases when the pump compresses the medium (compressor operation). Hence, make sure the temperature of the medium is sufficiently below the ignition temperature of the medium, even when it is compressed to the maximum permissible operating pressure of the pump. The maximum permissible operating pressure of the pump is stated in the technical specifications (chapter 4). If necessary, consider any external sources of energy, such as radiation, that may add heat to the medium. In case of doubt, consult the KNF customer service. Store all replacement parts in a protected manner and dispose of them properly in accordance with the applicable environmental protection regulations. Observe the respective national and international regulations. This especially applies to parts contaminated with toxic substances. For the purposes of the Machinery Directive 2006/42/EC, pumps are partly completed machinery, and are therefore to be regarded as not ready for use. Partly completed machinery may not be commissioned until such time as it has been determined that the 4 Translation of original Operating and Installation Instructions, english, KNF 120859-121488 08/13

Installation and connection Disengaging The IP protection class of the pump motor is indicated on the type plate. Install the pump at the highest point in the system to prevent condensate from collecting in the pump head. Protect the pump from dust. Protect the pump from vibrations and jolts. KNF recommends mechanically disengaging the pump from the piping system. This can be achieved with flexible tubing or pipes, for example. This will avoid transferring to the system any pump oscillations that may arise. 6.2. Electrical connection Extreme danger from electrical shock DANGER Only have the pump connected by an authorized specialist. Only have the pump connected when the power supply is disconnected. When connecting the device to a power source, the relevant standards, directives, regulations, and technical standards must be observed. In the electrical installation, arrangements (complying with EN 60335-1) must be made for disconnecting the pump motor from the electrical supply. The motors of the pump must be protected according to EN 60204-1 (protection against excess current, or overloading). For operating current see type plate. It is recommended that an additional Emergency Stop switch is installed. The pump must be installed so that contact with live parts is impossible. Connecting pump 1. Compare the supply data with the data on the motor-plate. For operating current see type plate. The voltage must not vary by more than + 10% and - 10% from that shown on the type-plate. 2. Open terminal box cover. 3. All pumps except versions with 3 phase motor: Connect the mains cables to the connections L1 and N of the pump motor. 4. Connection of pumps with 3 phase motor according to figs. 7 or 8. 5. Connect the earth (ground) wire to the motor. 6. Close the terminal cover box. 12 Translation of original Operating and Installation Instructions, english, KNF 120859-121488 08/13
Installation and connection Mains Fig. 7: Y-Connection (high voltage) Mains Fig. 8: -Connection (low voltage) Connected components Pressure relief device Pump exhaust 6.3. Pneumatic connection Only connect components to the pump which are designed for the pneumatic data of the pump (see Chapter 4, Technical data). Protect the pump with a pressure relief device between the pressure connection of the pump and the first shut-off valve. If the pump is used as a vacuum pump, safely discharge the pump exhaust at the pump s pneumatic outlet. Connecting pump A marking on the pump head shows the direction of flow. 1. Remove the protective plugs from the hose connection threads. 2. Connect the suction line and pressure line (see chapter 4, table 11 for the mounting dimensions). 3. Lay the suction and pressure line at a downward angle to prevent condensate from running into the pump. Operating and Installation Instructions, english, KNF 120859-121488 08/13 13
Operation 7. Operation Only operate the pumps under the operating parameters and conditions described in Chapter 4, Technical data. Make sure the pumps are used properly (see chapter 2.1). Make sure the pumps are not used improperly (see chapter 2.2). Observe the safety precautions (see Chapter 3). The pumps are intended for installation. Before putting them into service it must be established that machinery or equipment in which they are installed meets the relevant regulations. Hazard of the pump head bursting due to excessive pressure increase WARNING Do not exceed max. permissible operating pressure (see Chapter 4, Technical data). Monitor pressure during operation. If the pressure exceeds the maximum permissible operating pressure, immediately switch off pump and eliminate fault (see Chapter 9. Troubleshooting). Only throttle or regulate the air or gas quantity in the suction line to prevent the maximum permissible operating pressure from being exceeded. If the air or gas quantity in the pressure line is throttled or regulated, make sure that the maximum permissible operating pressure is not exceeded. Ensure that the pump outlet is not closed or constricted. Excessive pressure (with all of the related hazards) can be prevented by placing a bypass line with a pressure-relief valve between the pressure and suctions sides of the pump. For further information, contact our technical adviser (see front page for telephone number). Automatic starting can cause personal injury and pump damage WARNING When the operation of the pump is interrupted by the thermal switch, the pump will restart automatically after cooling down. Take all necessary care to prevent this leading to a dangerous situation. 14 Translation of original Operating and Installation Instructions, english, KNF 120859-121488 08/13
Operation Pump standstill Vapors as media With the pump at a standstill, open pressure and suction lines to normal atmospheric pressure. The pump may not start up against pressure or vacuum during switch-on. This also applies in operation following a brief power failure. If a pump starts against pressure or vacuum, it may block. This activates the thermal switch, and the pump switches off. Make sure that normal atmospheric pressure is present in the lines during switch-on. The life of the diaphragm is prolonged if the formation of condensate is avoided. Therefore the following precautions should be taken: Run the pump for a few minutes to warm it up before handling saturated or nearly saturated vapors. KNF recommends: When transferring aggressive media, flush the pump prior to switch-off (see Chapter 8.2.1) to increase the service life of the diaphragm.
