Airline connecTion hoSe rePlAcemenT
To replace an airline connection hose with a different type of
Scott airline connection hose, remove the hose from the pressure
reducer by loosening the fitting on the end of the hose with a
3
/
4
inch open end wrench until it separates from the pressure reducer.
See FIGURE 4.
Inspect the airline connection hose to be installed to be certain that
the hose is dry, free from obstructions, that the threads on the end
fitting are not damaged and that the O-ring seal on the hose fitting
is present and in good condition. If the threads are damaged or if
the O-ring seal is missing or damaged, DO NOT USE THE AIRLINE
CONNECTION HOSE; remove the airline connection hose from service
and tag for repair by authorized personnel.
Inspect the O-ring in the reducer and replace if damaged. Before
installing hose, be sure the check valve is properly installed in the
reducer and the O-ring is placed on the check valve.
To install an airline connection hose, slide the end with the fitting
through the sleeve on the waist belt from the right side as worn and
thread the fitting into the pressure reducer using moderate force.
