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 refueling immediately, use the emergency button to shut off
the dispenser, 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.
• 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 refueling process.
The PPE consists of:
Cryogenic Smock
Full Face Shield
Solid Shoes Capable of
Cryogenic Thermal
withstanding Cryogenic Media
Gloves
• Do not operate nozzle 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
• Do not point the nozzle directly at yourself or other persons at any time
INSTALLATION
Ensure the system is clean of debris,
vented
and
isolated
before any installation or servicing work
is carried out.
The N-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.
The nozzle is designed for the connection
1 5/16"-12 SAE J514 37° JIC male and must not
be used with any NPT or other thread sealing
adapters. The designated connections do not
require thread sealants.
Therefore,
do not use PTFE
sealing tape or
liquid seal for any sealing as electrical conducti-
vity may be insufficient and particles of the tape
commonly become loose and could clog the
nozzle valve or damage vehicle motor parts.
N-LNG complies with DIN EN ISO 12617:2017
and must meet its installation requirements.
Remove caps from nozzle.
Check sealing surfaces of connections at the
nozzle as well as the hose assemblies.
Needed Tools:
1 x Wrench EW M 30 ( for Elaflex nozzle )
1 x Wrench EW M 36/41 ( for Elaflex LNG hose assembly )
1 x Foaming agents or spray bottle with snoop or soapy water
Check if connections correspond in type an
size: 1 5/16"-12 SAE J514 37° JIC male /
female
Connect the hose to the nozzle. Torque to the
hose fitting suppliers recommended tightening
torque of 150 Nm.
Do not use pliers.
