These Operating Instructions are a translation of the original German
Operating Instructions 300758785_001_C1.
Obligation to Provide Information
Before installing and commissioning the pump, carefully read these
Operating Instructions and follow the information so as to ensure optimum
and safe working right from the start.
The Leybold ECODRY plus has been designed for safe and efficient opera-
tion when used properly and in accordance with these Operating Instructions.
It is the responsibility of the user to carefully read and strictly observe all safe-
ty precautions described in this section and throughout the Operating
Instructions. Moreover, observe the information in all additionally supplied
Operating Instructions for switches or valves, for example.The pump must
only be operated in the proper condition and under the conditions described
in the Operating Instructions. It must be operated and maintained by trained
personnel only. Consult local, state, and national agencies regarding specific
requirements and regulations. Address any further safety, operation and/or
maintenance questions to our nearest office.
DANGER indicates an imminently hazardous situation which, if not avoid-
ed, will result in death or serious injury.
WARNING indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.
CAUTION indicates a potentially hazardous situation which, if not avoided,
could result in minor or moderate injury.
NOTICE is used to notify users of installation, operation, programming or
maintenance information that is important, but not hazard related.
We reserve the right to alter the design or any data given in these Operating
Instructions. The illustrations are not binding.
Retain the Operating Instructions for further use.

0 Important Safety Information
0.1 Mechanical Hazards
1 Avoid exposing any part of the human body to the vacuum.
2 Select a secure place for the appliance (level surface).
3 The discharge port of the pump must not be blocked or constricted.
Never operate the pump with a seal-off stopper in place blanking off
the exhaust port. Operate the pump only with a connected vacuum
system to the intake flange.
4 With a closed exhaust pipe, the pump can generate up to 5 bar pres-
sure (absolute) on the exhaust. The exhaust pipes should be laid out
according.
5 Condensates from the pump can collect inside or at the exhaust,
escape and spill onto the floor, when operating the pump without an
exhaust line or during transport with an exhaust being not blanked off.
In this case there exists the risk of slipping.
6 Due to its weight the pump must only be lifted by duly trained and
qualified persons.
0.2 Electrical hazards
1 Housing parts must not be opened.
2 Connect the appliance only to a properly and professionally installed
mains outlet socket with protective earth connection.
3 Note the information on the IP type of protection.
0.3 Thermal Hazards
1 At the crane eye, the intake flange and the exhaust flange, the pump
may attain temperatures over 80 °C. There is the risk of suffering
burns. Note the danger symbols on the pump itself.
0.4 Hazards Caused by Materials and Substances
1 Fluoropolymers are used as sealants (FKM) and as lubricants (PFPE) in
the pumps. In case the pump suffers a severe mechanical failure, it
cannot be ruled out that toxic and/or corrosive substances may be
released due to thermal decomposition. Do not open the pump mod-
ule, and close off the inlet and exhaust flanges using blank flanges.
2 Before commissioning the pump, make sure that the media which are
to be pumped are compatible with each other so as to avoid hazard-
ous situations. Observe the instructions for proper and improper use of
the pump in Section 3.2.
3 When pumping hazardous gases we recommend a leak search on a
regular basis. Leaks in the pump cannot be ruled out under all circum-
stances. When pumping hazardous gases, the operator must ensure
that that leaks at the pump will not be a hazard. When pumping toxic
gases replace the gas ballast switch with a plug screw or connect a
gas supply to the gas ballast.

4 If required additional monitoring of the gas ballast quantities is neces-
sary from the side of the operator when a well-defined and ensured
dilution is necessary from the side of the process. The type of protec-
tion depends on the specific process and needs to be assessed by of
the customer.
5 When the pump has been used to pump hazardous gases, introduce
appropriate safety precautions before opening the intake or the dis-
charge connections. Before opening the pump, purge it for a longer
period of time with an inert gas. If necessary, wear suitable personal
protection equipment like gloves, breathing protection and protection
clothing, for example (see Material Safety Data Sheets for the sub-
stances in use, the chemical reactions and the by-products). Close off
the pump’s inlet and exhaust flanges using blank flanges.
6 When disposing of the pump, observe the applicable environment reg-
ulations.
0.5 Noise Hazard
1 The noise level of the pump during ultimate pressure operation corre-
sponds to the values stated in the technical data. In other operating
modes and depending on the connected vacuum system, higher val-
ues can be expected. Make sure that suitable protection measures are
taken to protect your hearing.

1 Description
The ECODRY plus is an eight-stage Roots pump. It is of the dry compressing
type and capable of evacuating chambers down to the medium vacuum
range.
The pump is connected to a single-phase supply using a mains power cable
and is powered via a built-in electronic drive unit. It is air-cooled. Bearings
and gears are lubricated using PFPE. The pump is therefore maintenance-
free from the customer’s perspective.
1.1 Supplied Equipment
The pump is delivered ready for use, except from a power cable. Inlet and
exhaust flanges are closed. The scope of delivery includes:
■2 centering rings, 2 clamping rings, 2 blank flanges for the inlet and
exhaust flanges
■D-sub 9-pin jumper for manual operation of the pump.

2 Transport and Storage
For transportation lift the pump at the crane eye or safely secured on a suita-
ble pallet.
The pump must not be tilted more than 30 degrees during transport.
For transports over short distances slightly lift the pump at the front side and
move it to the desired location.
Storage
Store the pumps only horizontally standing on their feet and castors.
The pump has been blanked off with blank flanges. Open the pump only
immediately before installing it.
Until putting the pump into service, store the pump in a dry place preferably
at room temperature blanked off with the supplied blank flanges.
The pump must be stored at the most for one year only. Longer storing with-
out turning the rotors will damage the bearings. Therefore, if you are storing
the pump for longer periods, it should be run once a year for at least 45 min-
utes and then returned to storage, as described in the following sections.
(The intake flange can stay sealed during this brief operation, the exhaust
flange must be opened.)
