Comply with notes on correct vacuum and electrical connections, see section Use and operation. The systems are designed for ambient temperatures during operation between +10 C and +40 C. Check the maximum temperatures if installing the system in a cabinet or a housing and make sure ventilation is adequate. Install an external automatic ventilation system if necessary.
7 NOTICE page 7 of 68 Ensure that the equipment and all components are suitable for the intended application. Use the system only for aspiration of liquids and filtration. Setting up and installing the system Equipment must be connected only to a suitable electrical supply and a suitable ground point. Failure to connect the motor to ground may result in deadly electrical shock. The supply cable may be fitted with a molded European IEC plug or a plug suitable for your local electrical supply. If the plug has been removed or has to be removed, the cable will contain wires color coded as follows: green or green and yellow: earth; blue or white: neutral; brown or black: live. The device has an internal fuse. Do not permit any uncontrolled pressurizing (e.g., make sure that an exhaust tubing cannot become blocked). Risk of bursting! Due to the high compression ratio of the pumps, pressure at the outlet port may be generated that is higher than the maximum permissible pressure compatible with the mechanical stability of the system. Always provide a free and pressureless exhaust line. Comply with maximum permissible pressures and pressure differences; see section Technical data. Do not operate the pumping unit with overpressure at the inlet or outlet. Check that line voltage and current conform with the equipment. (See rating plate.) Avoid overpressure of more than 0.2 bar in instances in which inert gas is connected.
8 NOTICE page 8 of 68 Provide a firm level platform for the equipment. Ensure a stable position of the pump without any mechanical contact except of the pump feet. Comply with all applicable safety regulations. Check fan regularly for dust/dirt, clean if necessary to avoid reduced ventilation. Avoid high heat supply. If the equipment is brought from cold environment into a room for operation, allow the equipment to warm up. (Watch for water condensation on cold surfaces.) The diameter of the an outlet tubing should be at the least as large as the diameter of the pump connections. Comply with all applicable and relevant safety requirements (regulations and guidelines), implement the required actions and adopt suitable safety measures. Ambient conditions NOTICE To the best of our knowledge the equipment is in compliance with the requirements of the applicable EC-directives and harmonized standards (see Declaration of conformity ) with regard to design, type and model, especially directive DIN EN This directive gives, in detail, conditions, under which the equipment can be operated safely (see also IP degree of protection). Adopt suitable measures in case of differences, e. g. using the equipment outdoors, installation in higher altitudes, conductive pollution or bedewing. Pay attention to the permissible maximum ambient temperatures (see Technical data ).
9 page 9 of 68 Operating conditions The devices have no approval for operation in or for pumping of potentially explosive atmospheres. The devices are not suitable to pump: - unstable substances and substances which react explosively under impact (mechanical stress) and/ or when being exposed to elevated temperatures without air, - self inflammable substances, - substances which are inflammable without air and - explosive substance The pumps have no approval for operation below ground. The pumps are not suitable for pumping dust. The devices are not suitable for pumping substances which may form deposits inside the pump. Deposits and condensate in the pump may lead to increased temperatures even to the point of exceeding the maximum permitted temperatures! Increased temperatures may cause ignition of inflammable substances that may have been deposited inside the pump during use. If there is a danger of the formation of deposits in the pump chamber (check inlet and outlet of the pump), inspect the pump chamber regularly and clean if necessary. Take into consideration interactions and chemical reactions of the pumped media. Ensure that the materials of the wetted parts are compatible with the pumped substances, see section Technical data. NOTICE If pumping different substances, it is recommended that the pump be purged with air or inert gas prior to changing the pumped media in order to pump out residues and to avoid reactions of the pumped substances with each other and with the pump materials.
10 page 10 of 68 Safety during operation Avoid interactions of the media in the collection bottle absolutely. Comply with material safety data sheets and notes on safe use of the manufacturer. Do not mix incompatible disinfectants and/or incompatible reagents / solvents as well as unknown substances. For example sodium hypochlorite (chlorine bleach) Incompatible chemicals and agents Acids or acidic compounds (e. g. hydrochloric acid, aluminium chloride) Ammonia containing compounds (e. g. ammonium hydroxide, quarternary ammonium salts) Organic chemicals (e. g. solvents, polymers, amines, oils) Metals (e. g. copper, iron) Hydrogen peroxide Reducing agents (e. g. sodium thiosulfate) Guanidine salts (e. g. guanidine hydrochloride, guanidine thiocyanate) Possible results of mixing with chlorine bleach Release of chlorine gas Formation of explosive compounds, release of chlorine gas and other hazardous gases Formation of chlorinated organics, release of chlorine gas and other hazardous gases Release of oxygen, overpressure, rupture of a closed system Production of heat, boiling Release of toxic gases, e. g. chlorine, chloramine, hydrogen cyanide Avoid the formation of dangerous reactions / gases in the BVC, especially in the collection bottle. If this is impossible dispose of dangerous gases at the outlet of the pump appropriately.
11 page 11 of 68 Adopt suitable measures to prevent the release of dangerous, toxic, explosive, corrosive, noxious or polluting fluids, vapors and gases. In such cases, install an appropriate collecting and disposal system and take protective action for pump and environment. If the equipment is used in combination with hazardous materials (e. g., in medical-microbiological laboratories) check all relevant safety and health requirements and determine the applicability of regulatory limitations prior to use if necessary. Use appropriate safety work materials and methods if necessary, e. g., steam sterilization, sterilization indicators or germicides. For notes concerning the sterilization of wetted parts, see the Technical Data section and Cleaning and decontaminating. It is the user s responsibility to ensure effective sterilization. Never operate a defective or damaged device. The user must take suitable precautions to prevent any formation of explosive mixtures in the expansion chamber or in the housing. In case of a diaphragm crack, for example, mechanically generated sparks, hot surfaces or static electricity may ignite these mixtures. Use inert gas for venting if necessary. Potentially explosive mixtures at the outlet of the pump have to be drained appropriately evacuated, or diluted with inert gas to non-explosive mixtures. Check the collection bottle regularly for cracks. Do never use a collection bottle with cracks nor expose it to vacuum. Use the system only in combination with the integrated hydrophobic filter (sterilizable) to protect pump and environment (people).
12 page 12 of 68 Comply with applicable regulations when disposing of chemicals. Take into consideration that chemicals may be polluted. Take adequate precautions to protect people from the effects of dangerous substances (chemicals, thermal decomposition products of fluoroelastomers), wear appropriate safety-clothing and safety glasses. Use only OEM spare parts and accessories; otherwise safety and performance of the equipment as well as the electromagnetic compatibility of the equipment might be reduced. The CE mark or the ctuvus mark (see rating plate) may become void if original equipment manufacturer parts are not used. In case of leaks in the manifold, aspirated substances might be released into the environment. Comply especially with notes on operation and use and maintenance. Due to the residual leak rate of the equipment, there may be an exchange of gas, albeit extremely slight, between the environment and the vacuum system.adopt suitable measures to prevent contamination of the pumped substances or the environment. NOTICE Maximum liquid level in collection bottle: approx. 80 %, depending on the application. (When working with lowboiling liquids, or liquids that tend to foam, the maximum liquid level might be reduced). Ensure that, in case of failure, the system will always return to a safe status. Provide appropriate protective measures (i.e., precautions which allow for the requirements of the respective application) even for the case of failure and malfunction. When operating the pump, the loss of pumping or venting must not lead to a critically dangerous situation under any circumstances.
13 NOTICE page 13 of 68 Electronic equipment is never 100% fail-safe. This may lead to an indefinite status of the equipment. Failure of the pumping unit (e. g., by power failure) or connected components, or change of parameters must not lead to a critically dangerous situation under any circumstances. In case of diaphragm cracks or leaks in the manifold, pumped substances might be released into the environment or into the pump housing. Comply especially with notes on operation and use and maintenance. Pay attention to the safety symbol hot surfaces on the equipment. Hot parts may cause burns if touched. Adopt suitable measures to prevent any danger arising from hot surfaces or electric sparks. Ensure that hot surfaces of the pump do not cause burns. Provide a suitable contact guard if necessary. In case of overload, the motor is shut down by a self-hold thermal cutout in the winding. Attention: Reset possible only manually. Switch off the pump or isolate the equipment from power supply. Identify and eliminate the cause of failure. Wait approx. five minutes before restarting the pump. Attention: In case of supply voltage below 100V ( V version), the lock of the cutout might be restricted and the pump might restart on its own after sufficient cooling down. Take suitable precautions if an automatic restart of the pump may lead to a critical dangerous situation. Maintenance and repair NOTICE Wear parts have to be replaced regularly. Under typical operating conditions, the projected lifetime of the diaphragms and valves is > operating hours. Bearings have a typical durability of h. Motor capacitors have a typical durability in the range of to h depending strongly on the operating conditions like ambient temperature, humidity or load.
14 page 14 of 68 Never operate the pump if covers or other parts of the pump are disassembled. Ensure that the pump cannot be operated accidentally. Isolate equipment from power supply before removing the cover! Before starting maintenance, unplug the equipment and wait 5 seconds to allow the capacitors to discharge. Attention: The pump might be contaminated with noxious or otherwise dangerous process chemicals that have been pumped during operation. Ensure that the pump is decontaminated before maintenance. Take adequate precautions to protect people from the effects of dangerous substances if contamination has occurred. Wear appropriate safety-clothing when you come in contact with contaminated components. Wear parts have to be replaced regularly. Never operate a defective or damaged pump. Check every motor capacitor regularly by measuring its capacity and estimating its operation time. Exchange old capacitors early enough to prevent a failure. When motor capacitors fail, they can get hot enough to melt or cause a flame which could be dangerous for persons and equipment in the vicinity. Motor capacitors have to be replaced by an electrician. Before starting maintenance, vent the system and allow sufficient cooling of the pump. Drain condensate, if applicable. Avoid the release of pollutants. NOTICE Ensure that maintenance is done only by suitably trained and supervised technicians. Ensure that the maintenance technician is familiar with the safety procedures which relate to the products processed by the pumping system. In order to comply with law (occupational, health and safety regulations, safety at work law and regulations for environmental protection) vacuum pumps, components and measuring instruments returned to the manufacturer can be repaired only when certain procedures (see section Notes on return to the factory ) are followed.
