Maintenance
Operate shutoff valves periodically and repair them, if seals tend to stick or leak. Notify all concerned
personnel before shutting off any gas supply.
WARNING: To protect the lives of patients, always notify the appropriate medical facility staff before
shutting off the supply of medical gas or vacuum through a shutoff valve. Do not close shutoff valves
except in cases of emergency or maintenance.
Clean the exterior of the valve boxes routinely with soap and water. Strong solvents may damage the Lexan
window.
Authorized hospital personnel should close shutoff valves in the event of fire, explosion or damage to the
pipeline systems or equipment.
In Alarm Valve Combo Unit boxes, the Shutoff Valve handles become accessible after the window has been
removed from the valve box.
To remove the window, grasp the ring and pull outwards. Turn valve handle towards you to shut off the
flow of gas or vacuum.
Zone Valves have a swingout design body which makes changing the internal components of the ball
valve easier.
All valve bodies can be accessed by loosening all bolts and nuts and removing only one bolt, at this point the
valve body can be swung out for servicing.
