3.2 Storage
Storing a new product If a new detector must be stored for more than three months:
Îleave it in its packaging,
Îleave the blanked-off flange in place on each port,
Îstore it in a clean, dry environment for a maximum of 3 months, in accordance with
the temperature conditions specified in the Technical Characteristics (see 11.2).
Beyond 3 months, factors such as temperature, humidity, salt in the air, etc., could dam-
age some components (elastomers, lubricants, etc.). If this happens, contact your ser-
vice centre.

4.4 Test methods
The test method is chosen depending on the part to be tested. For more information
about leak detection test methods, see Leak detector compendium on the website
www.pfeiffer-vacuum.com.
4.4.1 Hard vacuum test
ƔPart that can be connected to pipe and placed under a vacuum.
ƔPart that can be placed in a vacuum chamber.
Spray method This method involves removing the air from the part to be tested, connecting it to the de-
tector's analyzer cell, then spraying tracer gas on the points of the part that are likely to
leak.
The detector measures the flow of tracer gas that penetrates due to part leakage.
When spraying starts, the leak rate is not displayed instantaneously: there is a response
time which depends on the volume V being tested and the tracer gas pumping speed S
of the system at the opening of the part, according to the following relation:
T = V/S (where T = seconds, V = litres & S = l/s).
T is the time required for the leak rate to reach 63 % of the final value.
Bombing method The part is placed ahead of time in a pressurised gas tracer chamber.
The tracer gas penetrates the part through the potential leaks.
Then the part is removed from the chamber and placed in another vacuum chamber and
connected to the detector.
The detector measures the flow of tracer gas that leaks out of the part.
4.4.2 Sniffing test mode
ƔPart that can be connected to pipe and cannot be placed under a vacuum.
The part to be tested is pressurised with tracer gas.
The detector measures the flow of tracer gas
that leaks out of the part through a sniffer probe that moves across all the points prone
to leaking.
The detector measures the flow of tracer gas that leaks out of the part.
The measured leak rate is not an exact measurement of the leak. The sniffer probe only
detects part of the tracer gas escaping from the part, depending on the distance sepa-
rating the crack from the tip of the probe, and the direction of the leak in relation to the
probe.

5 Installation
5.1 Prerequisites for optimising measurement
To optimise pumping and measurement speed:
ƔUse pipe with a diameter equal to the diameter of the detector's inlet. The pipes should
be as short as possible and completely sealed.
ƔDo not use plastic hoses such as compressed air pipes.
ƔCheck that the connected part/installation is impermeable to tracer gas.
ƔTest only clean, dry parts/installations with no trace of water, vapour, paint, detergent
or rinsing products.
ƔTest that the entire line is completely sealed when the detector is attached to the
pumping circuit, to ensure that the connections are correct (pump, pipe, valves, etc.).
5.2 Operating conditions
Environmental conditions (see 11.2).
5.3 Securing the modules
Dimensions of the 3 modules (see 11.4).
5.3.1 Detection module
The detection module can operate in any position. The module is attached by the bracket
(4 x 4 slots). The mounting must be sufficiently rigid.
The module drawings are available on the operating manual CD-ROM.
Ventilation If ambient temperature can be over 40°C, it is necessary to provide external detection
module ventilation. Minimum ventilation flow is 45 m3/h = 0.75 CMM = 26.5 CFM.
DANGER
Explosion hazard.
For detecting leaks with 'hydrogen' tracer gas, the operator must use hydrogenated ni-
trogen (mix of 95 % N2 and 5 % H2).
NOTICE
Risk of pollution from solid substances
When applications generate particles, we recommend protecting the detector's inlet.
ÎInstall a inlet filter.
NOTICE
Detector ventilation
If there is insufficient ventilation, overheating could cause damage to the components:
ÎComply with the ambient operating temperature.
ÎDo not obstruct the air vents.
ÎLeave a gap of 100 mm around the air vents.
