blocked (if used)
4 . Unit defective
Odour Detected 1. Aircare – Air ltration unit
requires maintenance (if
used)
2. External air supply
contaminated
3. Headtop poorly tted or
damaged
Too much air Input pressure too high
Insuf cient heating Input pressure too low
or cooling effect

Speci cation)
2. Disconnect, then reconnect the
compressed air supply tube at
>4 bar pressure
3. Check Aircare unit
4. Replace unit
1. Check Aircare unit
2. Check quality of external supply
3. Re t or replace headtop
Adjust Air ltration unit or wall
regulator to reduce input pressure
(ensuring that whistle does not
sound)
