INSTALLATION AND OPERATING MANUAL
1.0 INSTALLATION
1.1 General description
The E DR vacuum pumps are able to run 24 hours a day and especially suited for harsh industrial
applications. They are supplied with self-lubricated long life graphite vanes to insure a long time
between service, combined with the easy accessible service of the pump, this results in a very short
service down time for the E DR-series.
1. Unpacking and Storage
Inspect the box and pump carefully for any signs of damage incurred in transit. Since all pumps are
ordinarily shipped EXW from our factory or regional warehouse, such damage is the normal responsibility
of the carrier and should be reported to them.
The inlet of the pump is covered with plastic caps to prevent dirt and other foreign substances
from entering the pump. Leave the cap in place until you are ready to pipe the pump to your
equipment.
The pump should be stored in a dry environment with normal air humidity (RH 0~80%, -10°C to
45°C), not for more than 12 months.
1.3 Location
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 cooling of the pump and motor.
Ambient temperatures should not exceed 45°C.
1.4 Power Requirements
A schematic diagram for the electrical motor terminal connections is located in the junction box of
the motor or on the motor nameplate. Typical wirings for Three Phase Motors are as below:

The motor must be connected according to the electrical codes through a fused switch in order to
protect the motor against electrical or mechanical overload conditions. The overload of the motor
starter must be set at a level equal to the full load motor current listed on the motor nameplate.
Check the rotation connection before starting the pump, the correct direction of rotation is marked by
an arrow on the pump casing.
Avoid more than 10 switches per hour.
After electrical connections have been made, the rotation of the motor must be checked. If
backward, reverse any two leads of the three at the power connection.
1.5 Vacuum Connections
Use a pipe size that is at least the size of the pump inlet connections. Smaller lines result in a reduced
pump capacity.
Pumps operating in parallel on a common main line should have a manual or automatic operated
shut-off valve or positive action check valve, installed in the suction line adjacent to the pump
suction flange. The built-in anti-suck back valve should not be used as a shut-off valve for the
vacuum system. Remove the plastic protective cap from the inlet port prior to connection of pump to
the system.
Should process gas contain dust or other foreign particles, a suitable in line (inlet) filter should be
connected to the inlet port. Consult Eurovacuum for recommendations.
The vacuum piping should be designed to ensure that no liquids such a condensate or liquid carried
over from the process can reach the pump. If this possibility exists, a knock-out liquid separator
should be installed. Consult Eurovacuum for recommendations.
The following thread sizes are standard on the pumps

.0 SAFETY
Please read the following safety notice carefully before operating the pump.
.1 General Notices
- Understand fully this installation and operating manual before operation.
- Any other person except authorized operator should not operate the vacuum pump
- When the pump 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.
. Warning labels and its explanation
Following warning labels are shown and attached on E DR series pumps
. .1 No oil:
No oil should be used in this pump and the intake of oil and oil mist must be prevented
. . Read operating instruction manual:
Read and understand operator’s manual before using this machine
. .3 Vane inspection
Inspect the size of the vanes after 3.000 hours of running
. .4 Location of the labels
The labels shall be shown on the top of sound shield of the pump.
.3 Risks and warnings
.3.1 Risk of burns
During operation the surface of the pump may reach temperatures of more than 70°C.
 Avoid contact with the pump during and after directly after operation.
.3. Risk of damage to hearing
If people are present near to the pump over extended periods then there is a risk hearing
damage.
 Ear protection must be used.
 Do not lubricate the compression chamber of the pump with oil or grease
.3.3 Damage to the pump
 Do not lubricate the compression chamber of the pump with oil or grease
 Avoid more than 10 on/off switches of the pump per hour

3.0 OPERATION
3.1 Start-up
Check rotation of the motor as described in paragraph 1.4 Power Requirements.
3. Stopping the pump
To stop the pump, turn off the power. An anti-suck back valve (built-in) for the pump installed in inlet
flange will prevent the air from back flowing into the vacuum chamber after the pump is shut down.
3.3 Operating Conditions
The E DR- xxx pumps are designed to run the ultimate vacuum levels stated in technical data (6.0)
for continuous operation. A vacuum regulator is installed on the pump, the desired vacuum level to
can be achieved by rotating the adjustment knob on the regulator.
The standard version is for use of dry air only, and may not be used in hazardous areas. Handling of
humid air or gases containing aggressive chemicals is possible only with specially configures units.
Consult Eurovacuum for assistance.
It is recommended for operating personnel who are working near the pump to wear ear protectors. If
noise below the designed dBA is required, an external sound enclosure can be added to the system,
provided adequate ventilation is provided
The ambient and suction air temperature must be below 45°C.
Caution: Any non compliance may lead to severe injury to persons and damage to the pump.
Caution: Ma imum number of motor starts per hour should not e ceed 10 per hour.
E cessive starting of the motor can cause overheating and premature failure of the motor.
4.0 MAINTENANCE
E DR-Series vacuum pumps require light maintenance. To ensure optimum performance, the
following maintenance steps should be followed:
4.1 Vanes check
Check the vanes width every 3.000 operating hours or annually.
The vanes width minimum sizes, if smaller width then they must be replace.
Pump type Minimum width
E DR- 010 18 mm
E DR- 016 22 mm
E DR- 025 28 mm
E DR- 040 28 mm
Caution: Only use original Eurovacuum vanes or order them at www.vanes.shop
4. Filter check
Check the filter cartridges inside the enclosure cover of the pump and clean/replace them when
necessary. You can order these from Eurovacuum or at www.vanes.shop

4.3 Maintenance Chart
Weekly: Check inline inlet filter element / Mesh. More often if high particulates in inlet stream.
Monthly: Clean the pump from dust and dirt. When inlet filter is installed: check the filter cartridge,
replace if needed.
Every 3.000 operating hours: Check the vanes size. Replace vanes if under the size.
Semi-Annually: Check cooling fan. More often if dirty environment.
