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.
