Bennett HF H35 Instruction Manual 16
•
Filters installed upstream from the dispenser and be in accordance with ANSI/CSA HGV 4.1, Standard for Hydrogen Dispensing Systems.
•
Read these instructions carefully and read all tags attached to the dispenser before starting installation. A dispenser that is not properly
installed will not perform properly and will void the limited warranty.
•
Installation of the Bennett product and all accessories (i.e. Nozzles, Hoses, and Breakaways) must be performed by a technician who
is trained and licensed in accordance with all codes, standards, and regulations.
CONTAINER STORAGE REQUIREMENTS
DANGER: STORAGE AREA TEMPERATURES SHOULD NOT EXCEED 125°F (52°C).
All installation specifications may vary by location. Gaseous hydrogen may be supplied in containers (cylinders or tubes) that are designed
and manufactured in accordance with all National Electrical Codes,
NFPA 2 – Hydrogen Technologies Code, State Codes, Local Codes , and
DOT (49 CFR Chapter I) specifications for the pressures and temperatures involved.
All installations must be performed by a technician who is trained and licensed in accordance with all codes, standards, and regulations.
PIPELINES AND CONTAINMENT SUMPS
NOTE: U.L. requires that electrical connections to the dispenser be made with threaded rigid conduit, and properly sealed
conductors. All dispensers and electrical connection boxes must be grounded per NFPA 70.
It is extremely important to ensure that all wiring and conduits are in accordance with all local, state, and federal regulations, including,
but not limited to,
NFPA 70 , NFPA 30 , and NFPA 30A .
The use of a UL approved containment sump designed for the Bennett Dispenser Model used is highly recommended. Follow the
containment sump manufacture’s installation instructions for proper installation .
FOUNDATION REQUIREMENTS
The dispenser must be mounted on a concrete foundation or a material having an electrical resistance not exceeding 1 MΩ as determined
by an approved method, no less than 10 ft. (3 m) from any building opening, and must be in accordance with all local, state, and federal
building codes regarding the requirements of seismic and wind conditions.
Note: Foundations used for supporting dispensers must be
designed and constructed to prevent frost heaving.
UPSTREAM HYDROGEN SUPPLY LINE FILTER
WARNING: TO PREVENT ELECTRICAL SHOCK, DISCONNECT FROM POWER SOURCE BEFORE INSTALLATION OR SERVICE.
CAUTION: Perform all preventative and schedule maintenance checks as recommended by the original manufacturer for all
NON-Bennett components.
CAUTION: Filters must be isolated, vented and be accessible for inspection, cleaning, and replacement, without taking apart
gas handling lines or disturbing any part of the dispensing device assembly in accordance with ANSI/CSA HGV 4.1, Standard
for Hydrogen Dispensing Systems.
For dispenser configurations that do not include an internal filter, a 5-micron filter must be installed on each supply line upstream of the
dispenser. Separate filters must be installed on each supply line. Refer to the dispenser footprint diagram for supply line locations. Filters
are to be installed and serviced per OEM installation instructions, preventative and scheduled maintenance.
Note: Upstream filter is not required on dispenser configurations which already have an internal filter installed.
