Installation Securing: DANGER There are two options: Install the system without securing. OR Screw the feet of the system to the surface with suitable fasteners. – Models 2BL2 041 - 141: Screws 4 x M10 Washers as per ISO 7093-1 Tightening torque: 10 Nm [7.38 ft lbs] – Models 2BL2 251 - 341: Screws 4 x M12 Washers as per ISO 7093-1 Tightening torque: 20 Nm [14.
Installation Fig. 5: Remove cover plate: Unscrew screws Insert the connecting cable: Thread the connecting cable into the cord grips on the side panel of the separator and push it through the cable inlet into the interior of the separator. Route the connecting cable into the terminal box of the installed unit via the cable entry opening.
Installation This also applies to: the protective conductor, the outer ground conductor. Both conductors can be recognised from their colour (green/yellow). WARNING Electrical danger! Clearance between bare live parts and between bare live parts and ground: at least 5.5 mm [0.
Installation 5.
Installation 5.4 Connection of pipes/hoses WARNING Danger from vacuum! Do not operate the unit unless the pipe / hose has been fitted to the inlet connection! If there is a danger that the system could suck in: Do not go near the inlet connection with long, open hair or loose fitting clothing, Do not look into the inlet connection or move your eyes in front of the inlet connection opening. Fig.
Installation Connect the inlet pipe: 5.4.2 Connect the system-side line for the pumped gases/vapours (intake line) to the connecting piece of the inlet connection (Item 037). The pumped gases/vapours are expelled into the surrounding area via the exhaust-air connection (Item B). They are not directed through a pipe or a hose. As a result, no assembly is required here.
Commissioning 6 Commissioning 6.1 Preparation and start-up Proceed as follows: WARNING Improper use of the system can result in serious or even fatal injuries!! Make sure that the following conditions are met: – The separator must be correctly filled with operating liquid. (watch fill level indicator). Have you read the safety precautions in Chapter 1, "Safety", Pg. 4 f.
Operation 7 Operation Start-up and shut-down in normal operation is identical to the procedure for commissioning. WARNING Improper use of the system can result in serious or even fatal injuries!! Have you read the safety precautions in Chapter 1, "Safety", Pg. 4 f.? Otherwise you may not carry out any work with or on the system! Position STANDARD Also be sure to read the safety precautions in Chapter 6, "Commissioning", Pg. 20! Fig. 12: 3-way valve (only 2BL2 041 - 141) NOTE 7.2.
Operation NOTICE Max. operating liquid level: Lower edge of the filling opening = level-indicator pointer at 1. Do not fill the separator above this level! Feed regulator: In case of operating liquid loss, a feed regulator (see Chapter 5.5, "Accessories", Pg. 19) can be connected with which the liquid level is automatically compensated. 7.2.
Shutting Down and Longer Standstill 8 Shutting Down and Longer Standstill WARNING Improper use of the system can result in serious or even fatal injuries!! Remove the cover plate (Item 064) and protective grille (Item 058) from the separator. Have a suitable catch container ready. Open the following drain openings (see Fig. 1, Pg. 3): – Drain opening on separator (Item 005) Have you read the safety precautions in Chapter 1, "Safety", Pg. 4 f.
Shutting Down and Longer Standstill To prevent standstill damage during storage, the environment must provide the following conditions: dry, dust-free, low-vibration (effective value of vibration speed veff ≤ 0.2 mm/s [0.008"/sec]). Take the following measures for commissioning following a longer standstill: Measure the insulation resistance of the motor. In case of values ≤ 1kΩ per volt of nominal voltage, dry winding.
Servicing 9 Servicing WARNING Improper use of the system can result in serious or even fatal injuries!! Have you read the safety precautions in Chapter 1, "Safety", Pg. 4 f.
Servicing WARNING Danger of burns and scalding from hot surfaces of the installed unit and from hot fluids! Only operate the system with the protective screen and cover plate installed! Allow to cool after shut-down! WARNING Improper use of the system can result in serious or even fatal injuries!! Do not reach into the installed unit through the opened intake or discharge connection! Do not insert objects into the installed unit through the openings! WARNING Improper use of the system can resul
Servicing Contamination/Problem Remedy Water consumption increases considerably after an extended period of operation. Clean cooling fins of water cooler. To do so, proceed as follows: Carry out protective measures for the use of compressed air: – wear personal protective equipment (protective gloves and safety goggles), – secure surrounding area. blow compressed air through cooling fins of water cooler (Item 027). Replace water filter (Item 095) and air filter (Item 096).
Servicing Contamination/Problem Remedy Impeller of installed unit is jammed. Free shaft by turning. Extremely hard water used as operating liquid Lime content > 15°dH). To do so, proceed as follows: Shut down system and secure against being switched on again. Remove cover plate (Item 064). Turn shaft of installed unit (Item D) by hand at fan impeller. If shaft cannot be freed by turning, installed unit must be decalcified. Soften operating liquid. OR Decalcify installed unit.
Servicing Contamination/Problem Remedy Allow decalcifying liquid to soak for at least 30 minutes. During this time occasionally turn shaft by hand at fan impeller. Have a catch container ready under the system. Drain installed unit: Open drain hole G¼ (Item E) of installed unit. The antiliming liquid will be discharged downward via the opening in the bottom of the separator. This will not cause chemical corrosion of the separator. Close the drain hole again.
Servicing Fault Cause Remedy Carried out by Motor does not start, no running noise. At least two power supply leads interrupted. Eliminate interruption by fuses, terminals or supply cables. Electrician Motor does not start, humming noises. One power supply lead interrupted. Eliminate interruption by fuses, terminals or supply cables. Electrician Impeller of installed unit is jammed. Free shaft by turning. See Chapter 9.1, "Maintenance", Section "Free shaft by turning", Pg. 28.
Servicing Fault Cause Remedy Carried out by System generates insufficient vacuum. System too small. Use larger system. Operator Inlet pipe too long or of too small diameter. Use shorter pipe or pipe of larger diameter for the inlet pipe. Operator Hose connections on inlet side or inlet pipe leaky. Check hose connections on the inlet side and inlet Operator pipe and seal leak if necessary. Operating-liquid flow too low.
Servicing Fault Cause Remedy Carried out by Major increase in water consumption compared to condition when new. Throttle valves are choked. Clean restrictor sleeves (Item 079 and 080). See "Drops of water squirting out of discharge connection". Operator/Service Air filter or water filter clogged. Replace air filter (Item 096) or water filter (Item 095). Operator/Service Clean separator (Item 001) if necessary. See Chapter 9.1, "Maintenance", Section "Clean separator", Pg. 27.
Disposal 9.3 Service/After-sales service Our Service is available for work (in particular the installation of spare parts, as well as maintenance and repair work), not described in these operating instructions (see front page of these operating instructions). Observe the following when returning systems: Before shipping: – Drain system completely as described in Chapter 8.1, "Draining", Pg. 23.
