Important Safety Precautions
Notice Indicates special requirements the user must comply with.
The INFICON Ecotec E3000 leak detector has been designed for safe and efficient
operation when used properly and in accordance with this Technical Handbook.
It is the responsibility of the user to carefully read and strictly observe all safety
precautions described in this chapter and throughout this Technical Handbook.
The Ecotec E3000 must only be operated in the proper condition and under the
conditions described in this Technical Handbook.
It must be operated and maintained by trained personal only. Consult local, state,
and national agencies regarding specific requirements and regulations.
Adress any further safety, operation and / or maintenance questions to our nearest
office.
Notice This can e. g. be the case if:
• the unit has visible damage,
• fluid has gotten into the device,
• the device is no longer working,
• the device has been stored for an extended period of time under unfavorable
conditions or
• after significant moving or transportation stresses.
Warning
Indicates procedures that must be strictly observed to prevent hazards to persons.
Caution
Indicates procedures that must strictly be observed to prevent damage to or
destruction of the Ecotec E3000 leak detector.
Warning
Presumed Risk:
If it is to be assumed that safe operation is no longer possible, the device is to be
taken out of service and secured against unsupervised operation.

Important Safety Precautions 0-7
kina22eIVZ.fm Technical Handbook(1206)
Failure to observe the following precautions could result in serious personal
injury:
Warning
Only 3-core mains cables having a protective ground conductor must be used.
Operation of the Ecotec E3000 with the ground conductor unconnected is not
permissible.
Warning
Do not stare into the LEDs of the sniffer line intentionally for extended times or at a
close distance as this may cause permanent damage to the eye.
Warning
Danger of electric shock.
Don’t touch voltaged parts with the sniffer tip. Test samples need to be
disconnected from electricity before leak testing.
Warning
For all contacts of the I/O Port a maximum voltage of 60 V DC or 25 V AC must not
be exceeded or reached to ground or ground equipment conductors.
According to the type of in- or outputs lower voltages had to be accepted. For this,
please refer to the information given in the responding chapters.
Warning
For all maintenance on the Ecotec E3000, the Ecotec E3000 must be disconnected
from power.
Warning
Before exchanging the air filter the Ecotec E3000 must be disconnected from
power.
Warning
Before exchanging the fuses the Ecotec E3000 must be disconnected from power.

0-8 Important Safety Precautions
kina22eIVZ.fm Technical Handbook(1206)
Failure to observe the following precautions could result in damage to the
equipment:
Warning
Before exchanging the lubricant reservoir the Ecotec E3000 must be disconnected
from power.
Warning
Dangerous gases pollute the machine.
So you must not use the machine for detecting toxical, acidity, microbiological,
explosive, radioactive or other noxious matters.
Warning
Caution: Danger of explosion
Hydrogen forms a highly explosive gas mixture with air.
Great caution is necessary when using hydrogen! No smoking, no naked flames,
avoid sparks.
Warning
Danger of explosion!
To use the Ecotec E3000 in explosion hazard areas could cause ignition of
flammable mixtures.
The Ecotec E3000 must only be operated outside of explosion hazard areas.
Caution
The Ecotec E3000 must not be operated while standing in water or when exposed
to drip water. The same applies to all other kinds of liquids.
This Ecotec E3000 should only be used in rooms.
Caution
Avoid contact of the Ecotec E3000 with bases, acids and solvents as well as
exposure to extreme climatic conditions.

Important Safety Precautions 0-9
kina22eIVZ.fm Technical Handbook(1206)
Caution
Ensure sufficient air cooling (see also Section 1.2)
Caution
Before installation remove the transportation lock.
Caution
In order to ensure adequate ventilation of the Ecotec E3000, a space of at least
20 cm 8) (8 in.) must be kept unobstructed to the sides. The clearance at the rear
must be no less than 10 cm (4 in.). Moreover, the Ecotec E3000 handles for
carrying the leak detector at the sides of the main unit must not be covered at any
time as these acts as air inlet and outlet. Avoid the presence of heat sources in the
vicinity of the Ecotec E3000.
Caution
Before connecting the Ecotec E3000 to the mains you must make sure that the
mains voltage rating of the Ecotec E3000 coincides with the locally available mains
voltage.
Caution
Do not suck in any liquids.
Caution
Permissible maximum input voltage PLC 28 V.
Caution
Permissible max. voltage and current for open collector outputs are: 28 V; 50 mA.
Caution
Maximum load rating relay outputs is 60 V DC / 25 V AC and 1 A per relay.

0-10 Important Safety Precautions
kina22eIVZ.fm Technical Handbook(1206)
Caution
The air filter should be checked for contamination at least every 6 months and
should be definitely exchanged after 2 years.
Caution
The lubricant reservoir may contain toxic substances from the pumped media.
Please dispose of lubricant reservoir as required by local regulations. A Safety Data
sheet for the lubricant is available on request.
Caution
Caution: Abrupt movements.
Abrupt movements can damage the running turbo pump.
Avoid abrupt movement and vibration of the instrument (e.g. running over cables,
door sills) during operation and up to 4 minutes after switching off since the turbo
pump can be damaged.

1 General Information
The Ecotec E3000 refrigerant leak detector is supplied ready for operation. However,
we recommend that you carefully read the Technical Handbook to ensure optimum
operating conditions right from the start. This handbook contains important
information on functions, installation, start-up and operation of the Ecotec E3000.
1.1 Introduction
1.1.1 Intended Use
The Ecotec E3000 is a refrigerant leak detector for sniffer applications. It may be
used to localise and quantify leaks in test samples if there is a refrigerant under an
overpressure within the test sample and when searching the test sample with a
sniffer probe from the outside (sniffer method). The use of this sniffer probe is
mandatory for proper operation and it is available as an accessory (Cat. No. 525-001
to 525-004).
Proper use includes:
• Conformance with the technical specifications
• Use of standard and original accessories
• Observance of the instructions and guidelines contained in this document
Caution
The Ecotec E3000 must not be operated while standing in water or when exposed
to drip water. The same applies to all other kinds of liquids.
This Ecotec E3000 should only be used in rooms.
Caution
Avoid contact of the Ecotec E3000 with bases, acids and solvents as well as
exposure to extreme climatic conditions.
Caution
Ensure sufficient air cooling (see also Section 1.1.2)
