Cryogenic gases or the handling equipment can cause serious harm to both infrastructure and
personnel if safety precautions are not followed.
A small gas release upon uncoupling is normal – but uncontrolled gas release to the atmosphere must
be avoided. If you suspect a leakage: stop refuelling immediately, evacuate the area and inform station
personnel.
• LNG is extremely flammable:
Open fires, smoking, sources of static electricity and the use of mobile phones or other
electric devices is prohibited in the area of gas transfer. Turn off vehicle engine before
refuelling / venting.
• Failure or improper use of this product can cause death, personal injury and property
damage.
LNG is extremely cold, also when released to the atmosphere.
SAFETY
Caution:
Please follow the safety instructions. Disregard can lead to serious injuries or death.
Personal protective equipment ( 'PPE' ) is required during the refuelling process.
The PPE consists of:
Cryogenic Smock
Full Face Shield
Solid Shoes Capable of
Cryogenic Thermal
withstanding Cryogenic Media
Gloves
• Do not operate safety breaks if there is any visible damage
• Stop refuelling process immediately if a permanent, uncontrolled release of LNG occurs (see also
chapter 'Troubleshooting' )
• Read the manual of the LNG vehicle and follow regulations from local authorities
• Keep area clear to avoid accidents
INSTALLATION
Ensure the system is clean of debris,
pressure-less
and
isolated
before any installation or
servicing work is carried out.
The SB-LNG is delivered ready for use. This installation must only be done by an authorised service
engineer who is trained to ensure compliance with all relevant national regulatory conditions.
It is intended for connections as described under 'Approval / Operating Conditions' and is designed
to withstand reasonable axial loads associated with proper handling practices. However, is not
designed to accept continuous excessive load values associated with maladjustment or poor installation.
Continuous excessive strain will equate to increased component wear and possibly premature failure if
not corrected.
Observe hose length to ensure proper handling. A sufficient hose length ensures a proper operation
within the stipulated minimum bending radius of the hose up to the maximum operation range.
Installation must comply with the requirements of the relevant authorities and applicable
country-specific regulations.
Needed Tools:
1 x Wrench EW M 36 / 41 ( for Elaflex LNG hose assembly )
1 x Wrench ( 50 mm – for Elaflex Safety Break )
1 x Wrench ( 8 mm – for breaking bolt nut )
1 x Wrench ( 4 mm – for breaking bolts )
1 x Screwdriver
1 x O-Ring removal tool ( EW 'ELAPICK' )
Ensure correct installation direction.
NOTE
:
Ensure that the dispenser allows the
max. pull force in all approach directions
without damage.
Hose Connection
ASSEMBLING AT DISPENSER
Dispenser Connection
Flange Connections
Before mounting the flanges, a seal that is
approved for LNG and corresponding flange
shape and size must be used, e.g. flat seals
made of graphite or grooved seals with a
suitable PTFE sealing surface.
Use suitable low-temperature screws e.g.
M12 x 55, A2-70. Observe the tightening torques
from the screw manufacturer. Do not tighten the
screws going round, but in diagonal order ( 1- 4 ).
