As a precaution against a supply failure or
pressure loss an audible low pressure warning
device should be fitted as described under
accessories.
NOTE: It is recommended that a new air
supply hose item (18) fig1 is used and specially
identified for breathing air. In the interest of
hygiene each user should have their own face
mask and hood.
HOSE LENGTH: Note 10m is the maximum
hose length that can be used due to the
minimum pressure requirements.
If longer hose length is required a portable
coalescing air filter device must be located at
the supply end of the10m hose and be capable
of supply pressure of 3.8 Bar (55 lbf/in²) at this
.
