roots blower starting

 ASSEMBLY AND PREPARATION FOR STARTING

• Before locating the unit or blower, the surface must be completely clean and dry, and free of any oil.

• The surface of the base must be scrubbed and clean, as well as the holes for the anchor bolts. Blow them with clean air if possible.

• The surface of the base must be completely smooth.

• After locating and supporting the machine, the surface must be drilled, and without moving the unit, the anchor bolts must be fixed in place. If the unit is installed onto the base of the cabin, the same procedure is carried out from the base.

• The connection with the thrust or suction tube (in which case it operates at low pressure) will be as stable as possible, through the rubber hose or axial compensator.

• If the unit is located in a room, check that the air intake is balanced and correct.

• Install an earth for the motor, muffler bed and soundproof cabin, to prevent charging and discharging of static electricity.

• In order to connect the electric motor, it is VERY IMPORTANT to know the type of start up and check the connections in the junction box. The technical and service data, shown on the specifications plate and the connection diagram must be checked. The motor comes with its own instruction manual. THIS WORK MUST BE CARRIED OUT BY SUITABLY QUALIFIED PERSONNEL.

 STARTING

• Ensure that it has been filled with oil.

• Re-tighten and check the filling and emptying caps.

• Check the TURNING DIRECTION of the blower, indicated by the arrow shown, by starting and stopping the motor after 1 second. Always look straight at the blower axis.

• Ensure that the installation tube is free of any obstacles and all the flow valves are open.

• Check that the suction side is free of any blockage and the filter cartridge is clean, if the unit has been stored or located in a dusty atmosphere.

• The unit is ready for start up.

 START-UP

If starting without load:

• Run it for 30 seconds and then stop it again, checking that the blower slows down gradually, without making any strange noises.

• Re-start the blower unit and check all the safety devices.

• The blower unit is ready for SERVICE.
