This equipment has been tested and found to comply
with the limits for a Class B digital device, pursuant to part
15 of the FCC rules. These limits are designed to provide
reasonable protection against harmful interference in a
residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause
harmful interference to radio communications. However,
there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause
harmful interference to radio or television reception,
which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
· Reorient or relocate the receiving antenna.
· Increase the separation between the
equipment and receiver.
· Connect the equipment into an outlet on a circuit
different from that to which the receiver is connected.
· Consult the dealer or an experienced
radio/TV technician for help.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference and
(2) this device must accept any interference received,
including interference that may cause undesired operation.
You are cautioned that changes or modifications not
expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.
The CE label shows that the product complies with the
basic requirements of the applicable directives. For the
declaration of conformity contact the manufacturer at

By hand, carefully thread the
regulator assembly into the cylinder.
Tighten the regulator until it is mated
flush to the neck of the cylinder.
· Take the cylinder and regulator and inspect for physical damage or debris,
reject if visible to the eye.
· Inspect the mating threads for damage or debris, reject if visible to the eye.

Filling of cylinder
Only qualified technicians trained in high pressure and flammable gases can carry
out fitting of regulators and filling of cylinders, and do so in accordance with local
laws and Health and Safety (H&S) regulations.
A leak check must be conducted after filling the cylinder.
Consult local H&S / facilities management for guidance on storage of cylinders and
advisable safety equipment.
Hydrogen fuel
When installing and operating hydrogen systems, hydrogen general safety guidance
should be considered, for more detailed information see:
ISO/TR 15916 – Basic considerations for the safety of hydrogen systems
Hydrogen purity is an important consideration for fuel cell performance, it should
comply with the specification in the table below for best performance:
For more details about hydrogen quality see the user manual for your FCPM
or contact Intelligent Energy Product Support, see Section 6
Fuel Characteristics Fuel Requirements
Hydrogen concentration > 99.90 %
Nitrogen, Helium, Argon < 0.10%
Oxygen < 50 ppm
Carbon Dioxide < 2 ppm
Carbon Monoxide < 0.2 ppm
Ammonia < 0.1 ppm
Sulphur containing compounds < 4 ppb
Max particle concentration < 1 mg/kg
Max particle diameter < 75 µm

8Assembly and connection3
3.4 Hydrogen connection
The Lightweight Hydrogen Regulator is designed to be connected to an
Intelligent Energy FCPM, please refer to the FCPM user manual for details of how
to make the hydrogen connection to that unit.
Ensure the hydrogen cylinder and FCPM are securely mounted
before proceeding.
Verify that the connector O-rings are in place and free from damage or debris.
Align the hose connector path with the regulator pins.
Push the hose connector and twist anti-clockwise. It will click when located.

1. Check cylinder pressure, refill if needed
2. Inspect the solenoid valve cable
Replace if damaged
If the steps above do not resolve the issue,
contact Intelligent Energy Product Support,
see Section 6
Loss of cylinder pressure Leak between cylinder
and regulator
Leak from the regulator
1. Place cylinder and regulator in a well-
ventilated space, preferably outdoors
2. Purge the gas from the cylinder by lifting
the cap of the PRV, see diagram in section 2.2
3. When the cylinder is empty. A person trained
in the use of pressurised gas should remove
the regulator from the cylinder and inspect
the sealing o-ring. Replace if damaged
4. Reassemble and refill the cylinder
5. Check for leaks
If the steps above do not resolve the issue,
contact Intelligent Energy Product Support,
see Section 6
Troubleshooting5
There are multiple ways to fill cylinders and Intelligent Energy has application notes
available for some fill options. Contact Intelligent Energy Product Support for details,
