Guidelines for typical installation
The air fuse should be installed directly between fixed or rigid pipework
and the flexible tube to protect the whole length of the flexible tube. Only
tubing after the air fuse is protected. The air fuse must be installed in the
correct orientation. Failure to do this will render it ineffective. When a shut
off valve is located before the air fuse, the valve must be opened slowly in
order to control initial air flow and avoid decompression effects which may
trip the air fuse.
It should be noted that the OSHA standard (29 CFR ChXVII Para
1926.302-b7) relating to pneumatic power tools states "All hoses
exceeding 1/2" inside diameter shall have a safety device at the source
of supply or branch line to reduce pressure in the case of hose failure."
