5.1 Prerequisites for optimising measurement
To optimise pumping and measurement speed:
● Use pipe wit a diameter equal to t e diameter of t e detector's inlet. T e pipes s ould
be as s ort as possible and completely sealed.
● Do not use plastic oses suc as compressed air pipes.
● C eck t at t e connected part/installation is impermeable to tracer gas.
● Test only clean, dry parts/installations wit no trace of water, vapour, paint, detergent
or rinsing products.
● Test t at t e entire line is completely sealed w en t e detector is attac ed to t e
pumping circuit, to ensure t at t e connections are correct (pump, pipe, valves, etc.).
5.2 Operating conditions
Environmental conditions (see 11.2).
5.3 Set-up
T e leak detector must be installed on a orizontal flat surface resting on its w eels.
DANGER
Explosion hazard.
For detecting leaks wit ' ydrogen' tracer gas, t e operator must use ydrogenated ni-
trogen (mix of 95 % N
2
and 5 % H
2
).
NOTICE
Risk of pollution from solid substances
W en applications generate particles, we recommend protecting t e detector's inlet.
Install a inlet filter (see Accessories chapter).
NOTICE
Detector ventilation
If t ere is insufficient ventilation, over eating could cause damage to t e components:
Comply wit t e ambient operating temperature.
Do not obstruct t e air vents.
Let a free space of 10 cm (4 inc es) minimum all around t e leak detector.
Store not ing under t e detector.
WARN NG
mmobilisation of the detector
T e detector must be immobilised w en it is being used or maintained.
 Immobilise t e leak detector by setting t e brakes on t e rear w eels.
NOTICE
Tracer gas concentration
You are advised to perform leak detection in a ventilated room.

Installation

5.4 Purge and inlet vent connection
T e detector is equipped wit an automatic purge optimizing t e detector functioning.
● Inlet vent and purge are connected to t e ambient air if no system is connected. Purge
maintains air flow inside t e leak detector.
● T e inlet vent status (open or closed) depends on parameters set by t e operator (see
7.4.6).
T e connector of t e purge and inlet vent is delivered equipped wit a protection filter
(see 4.2).
In addition to t e purge, it is advised (not compulsor) to use t e "Pollution" function (see
7.3.2).
5.4.1 Connection
Instead of t e protection filter, it is possible to connect t e detector to a nitrogen line (at
t e customer's expense). To use nitrogen allows to decrease t e background noise of
t e leak detector
Flow To guarantee best performance, t e nitrogen supply must be clean and filtered, wit t e
following c aracteristics:
– relative excess pressure: 200 Pa
– flow rate: 5000 sccm (if pressure= 1 bar (absolute) at t e inlet)
Usage pressure ● 0 to 0.3 bar relative (≈ 0 to 4.5 psig)
● 1.1 to 1.3 bar absolute (≈ 14.5 to 19 psig)
f the purge gas pressure is too high, the inlet valve could always be stay closed.
Procedure Remove t e filtrer from t e connector (see 4.2).
Attac t e nitrogen pipe to t e connector (see 4.2).
5.5 Connection to the mains power supply
CAUT ON
Risk of pollution
T e leak detector must not be used in an environment wit strong concentration in trac-
er gas. T e user as to make sure of t e good ventilation on t e place of use of t e de-
tector.T e manufacturer s all not be eld liable for any pollution of t e product wit trac-
er gas.
WARN NG
Pressurised circuit
To work safely on t e product, t e operator must:
Install a manual valve on t e nitrogen circuit at a distance of 3 m from t e product, so
