Service
Notify appropriate hospital personnel when
performing service or maintenance to medical gas
systems. Consult Troubleshooting Guide to
determine required repair. Outlets incorporate a
primary valve and secondary check. Secondary
check prevents system gas from escaping when
primary valve is removed for service. Refer to
Replacement Components for identification of
replacement part numbers.

Quick-connect and DISS valves may be
removed for replacement of seals and some

or DISS valve for leaks, apply leak detector
solution at primary valve opening both with and
without adapter connected. Bubbles indicate
pressure leaks. Large leaks may be audible.
