Function instruction Function instruction
In all cases, the motors are designed for operating voltages above or below 10% of the normal rating.
FUNCTION IN TRUCTION
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
MU T BE ADDED BEFORE U ING 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.
•lowly 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. uction 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. hutdown
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.

Tips for Use
Tips for Use
tart-up: excluding the first start-up, they are not particular demands attention, if not control the oil level. The pump must be used on a
stable and horizontal surface.
Vacuum pump oil: The condition and type of oil used in any high vacuum pump are extremely important in determining the maximum
achievable vacuum. The use of high vacuum pump oil is recommended. This oil has been specially blended to maintain maximum viscosity
at normal operating temperatures and to improve starts at low temperatures. Uses 0,5L MGF MGF Mineral Oil for vacuum pumps Art. 790100 .
Maintenance
Maintenance
Periodically check the condition of the pump and the electrical components (cable and electrical box). Replace the damaged parts with
original MGF MGF spare parts.
Lubrication: the first oil charge must be replaced after approximately 150/200 hours of operation. ubsequent changes must be made
every 400/500 hours or every 3/4 months.
The oil must be replaced even in the presence of humidity or dirt, which can damage the pump and affect its performance. It is essential to
use MGF MGF pump oil, which is optimal for ensuring correct pump operation ( Art. 790100 ).
Oil change procedure
1. Be sure the pump is warmed up.
2. Remove the oil drain cap. Drain contaminated oil into a suitable container and dispose of properly. Oil can be forced from the
pump by opening the inlet and partially blocking the exhaust with a cloth while the pump is running. Do not operate the pump for
more than 20 seconds using this method.
3. When the flow of oil has stopped, tilt the pump forward to drain the residual oil.
4. Replace the OIL DRAIN cap. Remove the exhaust fitting and fill the reservoir with new vacuum pump oil until the oil just shows at
the bottom of the sight glass. The approximate oil capacity of the pump is 180-800ml (reference the technical data).
5. Be sure the inlet ports are capped, then turn on the pump. Allow it to run for one minute, then check the oil level space. If the oil
is below the sight glass OIL LEVEL line add oil slowly (with the pump running) until the oil reaches the OIL LEVEL line. Replace the
exhaust fitting, making sure the inlet is capped and the drain cap is tight.
6. If the oil is badly contaminated with sludge that forms when water is allowed to collect in the oil, you may need to remove the oil
reservoir cover and wipe it out.
◦Another method of dealing with heavily contaminated oil is to force oil from the pump reservoir. To do this, allow the
pump to run until it it is warmed up. While the pump is still running, remove the oil drain plug. lightly restrict the
exhaust. This will back-pressure the oil reservoir and force the oil from it, carrying more contamination.
When the oil ceases to flow, turn off the pump.
Repeat this procedure as required until the contamination is removed. Replace the OIL DRAIN cap and refill the reservoir
to the proper level with fresh vacuum pump oil.

Common problems Common problems
Your pump has been for dependable use and long life. If something should go wrong, the following guide will help you get the pump back
into service as quickly as possible.
If disassembly of the pump is required, please check your warranty. The warranty may be voided by misuse or customer tampering wich
results in the pump being inoperable.
•Failure to start: Check the line voltage. The pump ned to start at ± 10% line voltage (loaded) at 32°F. At extremes, switching
between the startand run windings may occur.
•Oil leakage:
1. Be sure the oil is not a residual accumulation from spillage, etc.
2. If leakage exists the module cover gasket or the shaft seal may need replacing.
If leakage exists in the area of the oil drain plug, you may need to reseal the plug using a commercial pipe thread sealer.
•Failure to pull a good vacuum:
1. Be sure the vacuum gauge and all connections are in good condition and leak free. You can confirm leakage by
monitoring the vacuum with a thermistor gauge while applying vacuum pump oil at connections or suspected leak points.
The vacuum will improve briefly while the oil is sealing the leak.
2. Be sure the pump oil is clean. A badly contaminated pump may require several oil flushes.
3. Be sure the oil is at the proper level. For maximum pump operation, the oil must be even with OIL LEVEL line on the
sight glass when the pump is running. Do not overfill---- operating temperatures will cause oil to expand, so it will appear
at a higher level than when the pump is not running. To check the oil level, start the pump with the inlet capped. Check
the oil level in the sight glass. Add oil if necessary.
