airflow to drop to the minimum design flowrate or when the battery voltage drops to a level below
which it could not safely power the turbo unit. When either of these conditions occur a frequently
repeating audible bleep is emitted and in addition the Yellow LED on the top of the turbo unit flashes
if the filter is clogged or the Red LED flashes if the battery is low.
When either alarm condition occurs during use the wearer should leave the contaminated area
immediately and replace the filter or recharge the battery accordingly.
When first turning the unit on, the alarm will beep to indicate the correct functioning of the
alarm system. If the beep stops after a few seconds the airflow is sufficient to proceed
with using the unit.

collar to lock.
Turn on the turbo unit and put the belt round the waist joining the buckles at the front.
7. HEADPIECE FITTING
Refer to the separate instructions supplied with the headpiece for fitting instructions, adjustment
and use of the welding visor. Ensure that the face seal is tucked well under the chin and that the face
seal is giving a good fit.
