3 Diaphragm Vacuum Pumps UN828, UN838_I Description, Operating Conditions 1.3. Ambient Conditions When the pump is operating the following ambient conditions must be maintained: Ambient temperature during operation: between + 5 C + 40 C. The pumps must not be used in areas where there is a danger of explosion. The pumps must be protected from the effects of dust and water. During operation an adequate supply of air for cooling must be provided Pump materials See section 10. 3

4 Safety Diaphragm Vacuum Pumps UN828, UN838_I EC Directives / Standards 2. Safety For pumps with ac motors: The pumps have Protection Class IP00 or IP20, and so offer no protection against contact or foreign bodies. It is therefore essential to provide protection for persons against contact with live parts (e.g. electrical connections, motor windings), and moving parts (e.g. fan). Protection against the entry of foreign bodies must also be provided. The pumps have no protection against water. In this case too, as far as is relevant, measures to protect the pump must be taken before putting it into service. Note that the pumps may only be used for their intended purpose. The pumps must not be used in areas where there is a danger of explosion. The pumps are not suitable for aggressive media. For aggressive media there are other pumps in the KNF product programme - please ask us for detail. Components connected to the pump must be designed to withstand the pneumatic performance of the pump. For vacuum pumps, the exhaust gases must be safely disposed. Take care that safety regulations are observed when connecting the pump to the electricity supply. For pumps with a thermal switch: When the operation of the pump is interrupted by the thermal switch, the pump will re-start automatically after cooling down. Take all care necessary to prevent this leading to a dangerous situation. Specific safety instructions for the media being handled must be observed. Use only original KNF spare parts. 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 machine in which the partly completed machinery is to be assembled is in conformity with the provisions of the Machinery Directive 2006/42/EC. The following essential requirements of Annex I of Directive 2006/42/EC (general principles) are applied and observed: General Principles No. 1 No / /1.3.1 / / / 1.5.1* / 1.5.2* / / / / / (* only for pumps with AC motor) As these partly completed machinery are OEM-models the power supplies and the equipment for disconnecting and switching-off the partly completed machinery respectively have to be considered 4

5 Diaphragm Vacuum Pumps UN828, UN838_I Safety when mounting as well as over-current and overload protective gear. In addition a protection against mechanical parts in motion and hot parts, if existing, has to be provided when mounting. The pumps conform to the EC Directive 201/65/EU (RoHS2). The pumps conform to the EC Directive 2004/108/EC concerning Electromagnetic Compatibility. The following harmonized standards have been used: UN828_NE UN838_NE UN KNE UN828_NDC UN838_NDC DIN EN /2 DIN EN /2 DIN EN /3 DIN EN DIN EN Tab. 1 5

6 Installation Diaphragm Vacuum Pumps UN828, UN838_I Mechanical Electrical 3. Installation Pumps in the UN828 and UN838 range are OEM models intended for installation in equipment. When installing them make certain that accident prevention regulations, and safety instructions, including those for subsequent operation are observed. The safety instructions in section 2 must be observed. The dimensions of the mountings are given in Data Sheet. Install the pump so that the fan can draw in sufficient cooling air. For pumps with fan: Install the pump so as accidental finger contact is with the fan is impossible. Fit the pump at the highest point in the system, so that condensate cannot collect in the head of the pump - that prolongs working life. When making the electrical installation the safety regulations must be observed. In particular make sure that the electricity supply is isolated before trying to connect the pump. Compare the supply data with the data on the motor-plate. The voltage must not vary by more than +10 % and 10 % from that shown on the type-plate. The earth (ground) wire must be connected to the motor (not necessary on dc motors up to 24 V). With dc motors the wires must be connected to the correct poles. In the electrical installation, arrangements (complying with EN ) must be made for disconnecting the pump motor from the electrical supply. The pump must be installed so that contact with live parts (connection, possibly windings) is impossible. For pumps with ac motor: We recommend that a fuse is installed in the motor supply circuit; the operating current is given in Data Sheet. For pumps with ac motor: We recommend that a fuse is installed in the motor supply circuit; the operating current is given in Data Sheet. EMC-compatible Installation (for N828/838 DC) The Tests: Magnetic field with energy-technical frequency Electromagnetic HF field, amplitude-modulated Electromagnetic HF field, pulse-modulated Discharging of static electricity High frequency, asymmetric Fast transients were not carried out, cause the products do not contain electronic modules, which can be affected by these tests.

Remark 3: (quotation) Not to be used with input connections which are foreseen for a connection with a battery or a rechargeable battery which has to be removed or disconnected from the device for the recharge. Devices with a D.C. power input which are foreseen to be operated with an A.C. / D.C. converter have to be tested at an A.C. power input of an A.C. / D.C. converter fixed by the manufacturer. In case the converter was not fixed they have to be tested at an A.C. power input of a typical (usual) A.C. / D.C. converter. The test is applicable for D C power inputs which are foreseen for a permanent connection to cables which are longer than 10 m. Pneumatic Remove the protection plugs from the port threads. The accessories silencer, and hose connectors (if existing) are screwed into the port threads. Connect the suction and pressure lines. For flow direction see marking on the pump head or data sheet. Arrange the suction and pressure lines so that condensate cannot run into the pump (sloping lines). For vacuum pumps, the exhaust gases must be safely disposed. 7

8 Operation Diaphragm Vacuum Pumps UN828, UN838_I 4. Operation The pumps must not be used in areas where there is a danger of explosion. Specific safety instructions for the media being handled must be observed. If combustible media are used: Hazard of fires and explosions due to excessively high media temperature. 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. 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 (section 10). 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. Before pumping a medium, the compatibility of materials of pump head, diaphragm and valves with the medium must be checked (for pump materials: see section 10). The pump must not start against pressure or vacuum. When it is switched on the pressure in the suction and pressure lines must be atmospheric. This must be so even when the pump restarts after the power has been cut off for a short period. The maximum permissible operating pressure (see section 10) must not be exceeded. To prevent the maximum permissible operating pressure being exceeded, restriction or control of the air or gas flow should only be carried out in the suction line. If restriction or control of the air or gas flow is made on the pressure side ensure that the maximum permissible operating pressure is not exceeded. When the pump is at a standstill the inlet and exhaust must be at normal atmospheric pressure. For vacuum pumps, the exhaust gases must be safely disposed 8

9 Diaphragm Vacuum Pumps UN828, UN838_I Operation For pumps that may be employed as vacuum pump and compressor must not be used to produce vacuum and pressure at the same time. For pumps with a thermal switch: when the operation of the pump is interrupted by the thermal switch, it will re-start automatically after cooling down. Take all care necessary to prevent this leading to a dangerous situation. Diaphragm and valve plates/sealings are the only parts subject to wear. Wear is usually indicated by a drastic reduction in the pneumatic performance. When replacing parts proceed as described in section 5. Ambient conditions: see section

If a compressed air line is available, blow the parts out with it. 17

18 Trouble Shooting Diaphragm Vacuum Pumps UN828, UN838_I 7. Trouble Shooting Before working on the pump isolate the power supply securely, then check that the lines are not live. The following tips for fault-finding are best employed in the sequence shown. Pump produces no flow Thermal switch has opened due to over-heating. Disconnect pump from mains and allow to cool. Trace cause of over-heating and eliminate it. Connections or lines are blocked An external valve is closed, or a filter blocked. Liquid (condensate) has collected in the pump head. Let the pump run for a few minutes pumping air (if necessary for safety reasons: pumping an inert gas.) Install the pump at the highest point in the system. Diaphragms or valve plates/sealings are worn. Section 5 Servicing. Flow, pressure, or vacuum too low Compare the actual performance with the figures in section 10 or the data sheet. There is pressure on the pressure side, and at the same time vacuum, or a pressure above atmospheric, on the suction side. The pump is not designed for this condition. Liquid (condensate) has collected in the pump head. Let the pump run for a few minutes pumping air (if necessary for safety reasons: pumping an inert gas.) Install the pump at the highest point in the system. The cross-section of pneumatic lines, or connected components is too small, or they are restricted. To measure the performance, disconnect the pump from the system (small diameter tubing or a valve can significantly affect performance). There is a leak at a connector, in a line, or in the pump head. Diaphragm or valve plate/sealings are worn, or dirt is in the head: Section 5 Servicing. 18

19 Diaphragm Vacuum Pumps UN828, UN838_I Trouble Shooting If the pump does not operate properly and you cannot find any of the above faults, send it to the KNF Service Department. In order for KNF to repair the pump, the customer must provide a statement on the media which were pumped and on pump cleaning. Please fill out the corresponding KNF form, and submit it together with the pump. A sample statement for copying can be found in section 11 of these Operating and Installation Instructions. 19
