Handling and Setting up (pictures ᕡ to ᕣ)
Pumps that have reached operating temperature may have a surface temperature at position (Q) of more than 70° C. WARNING! Do
Not Touch.
Vacuum regulating valve (C), vacuum gauge (Y), greasing points (L) and filter housing (S) should be easily accessible. The cool air entry (E) and
the cool air exit (F) must have a minimum distance of 20 cm from any obstruction. The discharged cool air must not be recirculated. For maintenance
purposes we recommend a space of 0.4 m in front of the filter housing (S) and greasing points (L).
The SMV blowers can only be operated reliably if they are installed horizontally.
SMV models can be installed on a solid floor without bolting down. When fitting onto a framework we would recommend using anti-vibration mounts.
For installations that are higher than 1000 m above sea level there will be a loss in capacity. For further advice please contact your
supplier.
Installation (pictures ᕡ to ᕣ)
For operating and installation follow any relevant national standards that are in operation.
1. Vacuum connection at (A). The air handled can be exhausted into the atmosphere through the exhaust port (B).
Long and/or small bore pipework should be avoided as this tends to reduce the capacity of the pump.
2. The electrical data can be found on the data plate (N) or the motor data plate. The motors correspond to DIN/VDE 0530 and have IP 54
protection and insulation class B or F. The connection diagram can be found in the motor terminal box (unless a special plug connection is fitted).
Check the electrical data of the motor for compatibility with your available supply (voltage, frequency, permissible current etc.).
3. Connect the motor via a motor starter. It is advisable to use thermal overload motor starters to protect the motor and wiring. All cabling used
on starters should be secured with good quality cable clamps.
We recommend that motor starters should be used that are fitted with a time delayed trip resulting from running beyond the
amperage setting. When the unit is started cold, over amperage may occur for a short time.
The electrical installation may only be made by a qualified electrician under the observance of EN 60204. The main switch must be
provided by the operator.
Initial Operation (pictures ᕡ to ᕣ)
1. Initially, switch the pump on and off for a few seconds to check the direction of rotation against the direction arrow (O).
2. Connect the suction pipe at (A).
3. The vacuum can be adjusted by turning the regulating valve (C) according to the symbols on the top of the regulating valve.
Potential risks for operating personnel
Noise Emission: The worst noise levels considering direction and intensity (sound power), measured according to DIN 45635 part 3 (as per
3. GSGV), are shown in the table at the back. When working permanently in the vicinity of an operating unit we recommend wearing ear protection
to avoid any damage to hearing.
