Chapter1 INTRODUCTION
Nuclear materials notice
This equipment contains radioactive source material that emits gamma
radiation. Gamma radiation is a form of high-energy electromagnetic
radiation. In many cases, only persons with a specific license from the U.S.
NRC or other nuclear regulatory body may perform the following to the
source holder:
• Dismantle
•Install
• Maintain
• Relocate
• Repair
•Test
VEGA Field Service engineers have the specific license to install and
commission nuclear gauges, and can instruct you to safely operate your
level gauge. See page 26 for contact information.
Note: See the Radiation Safety for U.S. General and Specific
Licensees, Canadian and International Users Manual and the
Radiation Safety Manual Addendum of Reference Information
CD that came with the source holder and the appropriate
current regulations for details.

Introduction
14 LFXG-H Installation and Operation Guide
Unpacking the equipment
Unpack the unit in a clean, dry area.
Inspect the shipment for completeness. Check against the packing slip.
Inspect the shipment for damage during shipment or storage.
If the detector is included as a separate package in the shipment,
inspect the assembly for damage that may have occurred during
shipment or storage.
If there was damage to the unit during shipment, file a claim against the
carrier, reporting the damage in detail. Any claim on the VEGA for
shortages, errors in shipment, etc., must be made within 30 days of
receipt of the shipment.
If you must return the equipment, see the section “Returning equipment
for repair to VEGA” in the “Diagnostics and repair” chapter.
After unpacking the equipment, inspect each source holder in the
shipment to ensure that the operating handle is in the OFF position. If
you find the handle in the ON position, place it in the OFF position
immediately and secure it. Note: This applies to only some source
holders.
Caution: You must be familiar with radiation safety practices in
accordance with your U.S. Agreement State, U.S. NRC, or other
nuclear regulatory body before unpacking the equipment.
Note: Most source holder models accept a lock. Call VEGA Field
Service (see Customer Service page 26 for contact information)
immediately for further instructions if:
lThe source holder does accept a lock and there is no lock on it.
lThe lock is not secured.
lYou cannot secure the lock.
lThe operating handle does not properly move into the OFF
position.
See the Radiation Safety for U.S. General and Specific Licensees,
Canadian and International Users Manual and the Radiation Safety
Manual Addendum of Reference Information that came with the source
holder and the appropriate current regulations for details.

Storing the equipment
Source holder
If you must store it, do so in a clean, dry area. Be sure its shutter is in the
OFF or CLOSED position (if applicable). Check the current local regulations
(U.S. NRC, Agreement State, or other) to determine whether this area must
have any restrictions.
Gauge
Avoid storage at temperatures below freezing. Store the gauge indoors in
an area that has temperature control between +10 °C... +35 °C (+50 °F...
+95 °F) and < 50% relative humidity. Store equipment in dry conditions until
installation.
Certifications
This gauge is designed for certification compliance from the following
agencies”
• ATEX Standard
• CCOE (India)
• CEPEL/INMETRO (Brazil)
•CSA
• FM Standard
•IECex
• JIS (Japan)
• NEPSI (China)
