INSTALLATION AND OPERATING MANUAL
This manual is written to cover EVPP-Series Model vacuum pumps and compressors. The model
number is stamped into the nameplate. The number will appear as follows :
EVPP-Sxx (for Single stage) , EVPP-Dxx (for Double stage) or EVPP-xxx-Txxx (for systems).
Please identify the model number and serial number when ordering parts.
1.0 INSTALLATION
1.1 Unpacking
Inspect the box and contents carefully for any signs of damage incurred in transit. Since all of our
products are ordinarily shipped from our regional warehouse, such damage is the normal
responsibility of the carrier and should be reported to them.
The inlet and exhaust of the pump/compressor are plugged with plastic caps to prevent dirt and
other foreign substances from entering the pump/compressor. Remove these plugs when installing
the pump/compressor and before starting it.
The is a silencer/filter supplied with the pump/compressor, please mount this on the exhaust of the
vacuum pump or on the inlet in case of the compressor version.
1.2 Location
To reduce vibrations you should screw the four rubber feet inside the nuts located on the bottom of
the pump/compressor. Install the pump in a horizontal position on a level surface so that the pump
can be evenly supported on its rubber feet. Leave 10 ~ 15 cm of access around the pump to allow
proper cooling. Also adequate ventilation must be provided for the fans, radiator and motor.
1.3 Electrical connection
A schematic diagram for the electrical motor terminal connections is located on the housing of the
pump/compressor.
Check the voltage and frequency on the identification plate before starting the electrical supply to
the pump/compressor.
In the case of one of our DC-power versions there will be a control unit supplied with the pump.
Connect the 3 numbered wires of the control unit to the corresponding numbers on the
pump/compressor wires.
The 2 remaining wires, colour Red and Black will need to be connected to the supply voltage in the
following order: Red is connected to the Positive pole and Black is connected to the Negative pole or
common point in case of a vehicle.
2.0 SAFETY
Only normal air is permitted as working media. Do not evacuate corrosive liquid or vapour with the
pump.
Dirt will damage the pump so always use a suitable inlet filter. After the pump has been stopped, air
will gradually flow back into the evacuated spaces in the vacuum version or will escape from the
compressor version. If this is undesirable, it will be necessary to fit a check valve in front of the inlet
port on the vacuum pump or on the exhaust of the compressor, look on the Eurovacuum catalog for
the details of these check valves.

The standard pump/compressor cannot start against vacuum/pressure. Contact Eurovacuum for an
alternate vacuum pump/compressor designed to meet your demand.
Improper disassembly or repair will damage the pump/compressor. Only qualified personnel should
make repairs.
The pump/compressor is maintenance-free. Do not lubricate any of the parts with oil, grease, or
petroleum products nor clean with acids, caustics, or chlorinated solvents at any time as this will
affect the lifetime of the unit.
2.1 General Notices
- Understand fully this installation and operating manual before operation.
- The other person except authorized operator should not operate the pump/compressor.
- When the pump/compressor is not properly working, it should be stopped immediately.
- Eurovacuum shall have no liability for any accident and failure arising from no compliance with
instructions in this manual.
3.0 Warranty
EVPP-Series vacuum pumps/compressors have a warranty of 12 months from the moment of the
date of shipment. They are only valet when the pump/compressor has been properly installed and
operated under normal conditions of use like mentioned inside this manual.
4.0 PROBLEM SOLVING
4.1 Problem
Pump/compressor does not start.
4.1.1 Possible Cause
No main power supply.
Remedy : check the main power supply and cables.
4.1.2 Possible Cause
Wrong voltage or frequency.
Remedy : check the required voltage and frequency on the pump/compressor and order the
correct pump/compressor for your supply power.
4.1.3 Possible Cause
Capacitor defective.
Remedy : Check capacitor and replace if necessary.
4.1.4 Possible Cause
There is full vacuum (vacuum version) or full pressure (compressor version) in the pipe system or
tank.
Remedy : vent the system to atmospheric pressure and the pump/compressor will start again, if
this happens more often than fit an check valve before the pump/compressor and the pipe system
and/or tank.

4.1.5 Possible Cause
Motor defective.
Remedy : return to the factory for repair.
4.2 Problem
Pump/compressor does not reach the ultimate vacuum/pressure.
4.2.1 Possible cause
The system is leaking.
Remedy : repair the leaking parts on the system.
4.2.2 Possible Cause
Inlet filter or exhaust filter is dirty
Remedy : replace filter cartridges.
4.2.3 Possible Cause
Cylinder or cup seal defective
Remedy : replace cylinder or cup seal.
4.2.4 Possible Cause
Plate valve defective
Remedy : replace the plate valve.
4.2.5 Possible Cause
Vacuum/pressure gauge defective or inaccurate.
Remedy : use another gauge to measure the vacuum/pressure.
4.2.6 Possible Cause
Pump/Compressor is too small for the system.
Remedy : ask Eurovacuum to supply you a bigger pump/compressor suitable for your system.
4.3 Problem
Pump is very noisy.
4.3.1 Possible Cause
Vibrations being transferred to the base and/or enclosure.
Remedy : use a suitable anti-vibration protection.
4.3.2 Possible Cause
Defective bearing(s)
Remedy : return the pump/compressor to Eurovacuum or a by Eurovacuum certified local service
centre for repair.

4.3.3 Possible Cause
Cylinder or cup seal defective
Remedy : replace cylinder or cup seal.
4.3.4 Possible Cause
Plate valve defective
Remedy : replace the plate valve.
4.4 Problem
Pump becomes too hot.
4.4.1 Possible Cause
Cooling air supply is insufficient.
Remedy : provide for adequate ventilation with cool air.
4.4.2 Possible Cause
Ambient temperature is too high.
Remedy : relocate the pump/compressor to area where the ambient temperature is below 40˚C.
4.4.3 Possible Cause
Process air is too hot (only on vacuum version).
Remedy : add an cooling system to cool down the process gas below 30˚C before entering the
vacuum pump, this cooling can also be achieved by using a longer inlet piping.
