2.4 Maintenance safety
Please observe the following guidelines prior to maintaining any
Kraus CNG dispenser:
Only properly trained or qualified
personnel should be permitted to
maintain and repair CNG equipment.
When in doubt, please refer to the
equipment supplier or service agent.
Always adhere to the manufacturer
guidelines for proper installation and
maintenance of all dispensers and
dispenser-components.
All maintenance and repair work of
pressure vessels and other safety
equipment must be conducted under the
appropriate codes, then tested and
accepted by the inspection authority.
The dispenser must be powered-off and
completely vented, unless otherwise
specified.
Never perform welding processes near
gas systems.
Always cover disassembled parts and
openings with a clean rag, paper, or
adhesive to keep them clean and avoid
contamination.
Do not clean any parts with flammable
solvent. Clean and rinse all parts carefully
with compressed air.
Be sure to wear necessary safety
equipment during maintenance and
repair. Eye protection is absolutely
necessary when cleaning with
compressed air.
Wear hearing, hand, and eye protection
when bleeding filters and lines. Be sure to
keep body parts away from the discharge
orifice.
Do not touch bare wires and live current-
carrying parts while the electrical system
is energized.
Never tighten or loosen any fitting when
it is under pressure.
