Function instruction
In all cases, the motors are designed for operating voltages above or below 10% of the normal rating.
FUNCTION INSTRUCTIONS
Verify that the voltage and frequency at the output match the specifications on the pump motor label.
All installation operations must be carried out before starting and with the pump strictly stopped. Check the ON-OFF switch to make sure it
is in the OFF position before plugging the pump into an outlet. While no special precautions are necessary for normal commissioning, a
series of operations must be carried out prior to initial commissioning.
1. Oil loading/unloading
Remove the drain plug from the end of the pump handle. The vacuum pump was originally tested and shipped without oil in the tank. OIL
MUST BE ADDED BEFORE USING THE MACHINE. Failure to introduce oil seriously damages the machine and voids the warranty.
All installation operations must be carried out before starting and with the pump strictly switched off.
•
Make sure the oil drain valve located under the reservoir is closed before adding oil.
•
Remove the oil cap located on the top of the tank and insert the oil bottle.
•
Slowly add oil until the oil is just visible at the bottom of the sight glass. The approximate oil capacity of the pump is 180-600ml (refer
to technical data). Avoid overfilling the reservoir which would cause the pump to overheat
•
Replace the oil plug and remove the plug from one of the inlet ports. Turn the engine switch to ON. When the pump runs smoothly,
replace the plug on the inlet port. This can take from two to 30 seconds depending on the ambient temperature. After the pump has
run for about one minute, check the oil level in the sight glass. The level should be at the same level as the oil level line on the sight
glass. Add oil if necessary.
Note: When the pump is running, the oil level should be at the same level as the line on the sight glass. Insufficient filling will result in poor
vacuum performance. Overfilling can cause oil to leak out of the drain.
2. Suction tube
Connect the suction pipe to the pump and to the manometric group. Reduce, if possible, curves, throttling and pressure drops in general, in
order to improve the final vacuum degree and evacuation speed
3. Electrical connection
Check that the characteristics of the electrical power supply network are compatible, that the electrical network complies with Community
legislation, is equipped with a differential thermal breaker and earth connection. When using extension cables, make sure that they have an
adequate section for the electrical load to be supported.
4. Ventilation
The
MGF
MGF
vacuum pump has been designed to work in optimal temperature conditions (40-50 °), thanks to the forced ventilation and the
efficiency of the exchange surfaces. Although it is equipped with a thermal protection device, it is good to make sure that there are no
obstacles to the air flow generated by the fan.
5. First start-up
Each pump undergoes a rigorous running-in cycle, however, before starting work, it is advisable to leave the pump running for 10 minutes
with the suction port closed.
6. Shutdown
To help extend the life of the pump and promote easy start-up. Follow these procedures for shutdown.
•
Close the manifold valve between the pump and the system.
•
Remove the tubing from the pump inlet.
•
Plug the inlet port to prevent contamination or loose particles from entering the pump.
