CAUTION
Certain
detectors
are fitted with oil pumps: the oil load
needed
for pump operation is in
separate cans.
We also
recommend
that the user drains the pump before re-shipping
the equipment.
CAUTION
When relevant, remove the protection which blocks the
outlet of the pump, on the rear of the leak
detector.
We
recommended connecting
this outlet to a gas evacuation
circuit for the oil seal pump.
This
circuit should have as little
excess pressure
as
possible (less
than 0.3 bar).
CAUTION
Storage
of the equipment: our equipment can be stored
without
special precautions
for up to 3
months
(room
temperature
between 5°C and 40°C). For longer periods,
factors
such
as humidity
content, temperature,
salty
atmosphere,
etc., can
cause
damage to certain
«sensitive»
parts
(elastomer seals,
lubricant, etc.).
CAUTION
Check
the pumping
conditions
of the
detector:
the leak
detectors
are not equipped for pre-pumping of corrosive
gases, condensable
vapours of liquids, even in small
quantities.
CAUTION
The
manufacturer can not take any responsability or apply
any warranty on a leak
detector
which is
used
with a
presence
of
corrosive
or dangerous
gases:
all our leak
detectors
are not
designed
to pump dangerous
substances.
W
ARNING
A helium leak
detection
operation must be made in a safe
environment
for the user and the equipment: all precautions
must be taken by the user of the leak
detector
in that respect
(especially
to eliminate the
presence
of
chemicaly,
aggressive,
toxic or hazardous
substance
prior to the
test
operation).
The
manufacturer
has
no control over the
types
of
gases
pa
ss
i
n
g
through the p
um
p
s
.
CAUTION
Ensure
that parts or
enclosures connected
to the inlet of the
detectors
can handle a
pressure
drop of 1 bar relative to
atmospheric
pressure.
CAUTION
If the
detector
rotates in an axis perpendicular to the axis of
rotation of the
secondary
pump, there is a risk of
seizure
of
the
secondary
pump.
