6. Operation
6.1. Initial start-up preparation
Note:
The pump is supplied filled with oil.
▪ Check the process lines for the correct size to prevent high pressure drop and
for cleanliness to protect the vacuum pump.
▪ Make sure the pump outlet is not obstructed.
▪ Check that the electrical connections correspond to the applicable codes and
that all wires are clamped tight to their terminals. The installation must be
earthed and protected against short circuits by fuses of the inert type in all
phases. An isolating switch must be installed near the vacuum pump.
▪ Switch on the voltage and switch it off immediately. Check the direction of
drive motor rotation while the motor is about to stop. The correct direction of
rotation of the drive motor is indicated by an arrow shown on the motor fan
cowl. If the direction of the drive motor is incorrect, open the isolating switch
and reverse two incoming electric lines. Incorrect rotation of the drive motor
may cause damage to the vacuum pump.
▪ Start and run the vacuum pump for a few minutes. Check that the vacuum
pump operates normally.
Note:
If you intend to apply the vacuum pump on humid applications, it is
recommended that the unit can achieve optimal running temperature before it
is effectively put in operation. This can be done by running the unit against a
closed suction line for 30 minutes with open gas ballast.
Gas ballast location and use is indicated on the pump data plate.
If the air intake filter (optional) is delivered loose, mount it in a leak-tight manner.
Install the air intake filter (optional) in a horizontal position to prevent filtered dust
falling into the pump inlet when replacing the air intake filter element and
resulting damage to the pump.
6.2. Start the pump
CAUTION: EXCESSIVE ENERGY CONSUMPTION
Risk of damage to equipment. To avoid excessive energy consumption and
damage to the vacuum pump the maximum allowed starting frequency is 6
starts per hour.
For more frequent operation, let the pump operate continuously and control the
vacuum demand by a pitot valve on the pump inlet.
To start the pump:
1. Check oil level and oil condition.
