t e security instructions in t is operating manual and comply wit t em.
It is t e operating customer’s responsibility to protect all operators against t e dan-
gers associated wit t e product, wit t e media pumped and wit t e entire instal-
lation.
Obligation to keep the operating instructions available
Any person responsible for installing, using or maintaining t e product must be able to
consult t e product operating instructions and maintenance instructions.
It is t e operator's responsibility to make t ese manuals available for consultation at

Transport and storage
3 Transport and storage
Upon delivery, c eck t at t e product as not been damaged during transport. If t e
product is damaged, take t e necessary measures wit t e carrier and notify t e manu-
facturer. In all situations we recommend:
Keeping t e product in its original packaging so it stays as clean as it was w en dis-
patc ed by us. Only unpack t e product once it as arrived at t e location w ere it will
be used.
Keeping t e packaging (recyclable materials) in case t e product needs to be trans-
ported or stored.
Keeping t e blanking flanges on t e various inlet ports w en t e product is not in use.
3.1 Transport
3.2 Storage
● Store t e electronic module, t e detection module and t e industrial control panel in
t eir original packaging (wit t e detection module's turbomolecular pump in a vertical
position).
● Do not store t e product wit a desiccant in its packaging.
Storage valve T e detection module is delivered wit a blanking flange fitted wit a manual storage
valve on one of t e two Gross Leak inlet ports. T is valve is used to place t e product
under vacuum, protect it from any pollution and t us ensure its performance is optimal.
● Valve fitted wit a female 1/8 connector.
● T e lever on t e control valve as been removed to transport t e detector. T e lever
is delivered in t e detector packaging (kit wit parts 2, 3 and 4). It is not necessary to
refit t e lever to remove t e blanking flange.
NOTICE
Work/Handling the detector
T e operator must not work on t e product to move it or carry out maintenance until it
as come to a complete s utdown! W en t e circuit breaker is set at O, you must:
Disconnect t e mains cable at bot ends.
Wait 5 minutes starting to work on t e product.
NOTICE
Obligation to inform
We took care to provide you wit a clean product. So t at it stays clean, we recommend
storing it in its original packaging.

● T e blanking flange/valve assembly (1) must be removed before using t e detector,
w atever t e installation configuration of t e detector in t e customer's equipment
may be. Keep it in order to re-use it subsequently when transporting the detec-
tor or storing it for an extended period.
Procedure for storing a
new product
Procedure to be used for storage lasting more t an t ree mont s:
● Leave it in its packaging.
● Leave t e blanking flange in place on eac inlet port.
● Store it in a clean, dry environment for a maximum of 3 mont s, in accordance wit
t e temperature conditions specified in t e Technical Characteristics (see 11.2).
Beyond 3 mont s, factors suc as temperature, umidity, salt in t e air, etc. could dam-
age some components (elastomers, lubricants, etc.). If t is appens, contact your ser-
vice centre.
Procedures for extended
periods of storage after
use
Procedures to be used before any periods of extended s utdown and/or before disman-
tling t e detector: t e detection module t us remains under vacuum, avoiding a long de-
gassing time t e next time t e equipment is started up.
Keeping the detector in the customer's installation:
Perform a test.
Stop t e detector and wait for t e turbomolecular pump to completely stop.
Dismantling the detector from the customer's installation:
Stop t e detector and wait for t e turbomolecular pump to completely stop.
Disconnect t e detection module from t e installation.
Place a blanking flange on eac Hig Sensitivity and Normal inlet port.
Place a standard blanking flange on one of t e two Gross Leak ports.
C eck t at t e control lever is fitted on t e blanking flange/storage valve assembly (fit
it if it as been removed) and t at t e valve is open.
Place t e blanking flange/valve assembly on t e 2
nd
Gross Leak port.
Connect a pumping system (or a primary pump) to t e storage valve and create a vac-
uum inside t e detection module.
Close t e storage valve and remove t e control lever to prevent any air accidentally
entering (keep t e lever for subsequent use).
Disconnect t e pumping system from t e storage valve.
Store t e detection module in its original packaging.
f the lever is lost, a screwdriver can be used to open and close the valve.

4.4 Test methods
T e test met od is c osen depending on t e part to be tested. For more information
about leak detection test met ods, see Leak detector compendium on t e website
www.pfeiffer-vacuum.com.
4.4.1 Hard vacuum test
● Part t at can be connected to pipe and placed under a vacuum.
● Part t at can be placed in a vacuum c amber.
Spray method T is met od involves removing t e air from t e part to be tested, connecting it to t e de-
tector's analyzer cell, t en spraying tracer gas on t e points of t e part t at are likely to
leak.
T e detector measures t e flow of tracer gas t at penetrates due to part leakage.
W en spraying starts, t e leak rate is not displayed instantaneously: t ere is a response
time w ic depends on t e volume V being tested and t e tracer gas pumping speed S
of t e system at t e opening of t e part, according to t e following relation:
T = V/S (w ere T = seconds, V = litres, S = l/s).
T is t e time required for t e leak rate to reac 63 % of t e final value.
Bombing method T e part is placed a ead of time in a pressurised gas tracer c amber.
T e tracer gas penetrates t e part t roug t e potential leaks.
T en t e part is removed from t e c amber and placed in anot er vacuum c amber and
connected to t e detector.
T e detector measures t e flow of tracer gas t at leaks out of t e part.
4.4.2 Sniffing test mode
● Part t at can be connected to pipe and cannot be placed under a vacuum.
T e part to be tested is pressurised wit tracer gas.
T e detector measures t e flow of tracer gas t at leaks out of t e part t roug a sniffer
probe t at moves across all t e points prone to leaking.
T e detector measures t e flow of tracer gas t at leaks out of t e part.
T e measured leak rate is not an exact measurement of t e leak. T e sniffer probe only
detects part of t e tracer gas escaping from t e part, depending on t e distance sepa-
rating t e crack from t e tip of t e probe, and t e direction of t e leak in relation to t e
probe.

position.
● For maintenance needs, it is sometimes necessary to swing aside t e top part of t e
detection module in order to ave access to t e components (see the Maintenance
instructions for the detector). Never leave t e module in t is position after any main-
tenance work. The top part of the module must always be folded down when us-
ing the detector.
● Ensure t ere is sufficient room around t e detection module to allow t e module to be
dismantled for maintenance.
