8. Ransburg A WARNING gt Arcing fire hazard exist if ungrounded metal connections air or fluid are used in the spray area Use plastic non con ductive connections or ensure metal connections are at ground potential y Do not use PTFE tape or pipe dope on any air beyond the final air filter for BEARING AIR The tape or dope may break free and cause plugging of the turbine air bearings and result in turbine failure See page 17 for tubing connections and sizes Bearing Air Use tubing clear see through nylon natural to connect a properly filtered air source to the bear ing air fitting on the manifold It is recommended to use tubing clear see through for bearing air so that any contamination that gets past the final bearing air filter will be apparent Also refer to the previous Caution Under the Operation section which follows there is a Caution regarding bearing damage if the turbine is run while bearing air is off Since the turbine must not be operated without first turning on bearing air it is required to provide some means of assuring the presence of bearing air before turning the turbine On One method is by interlocking the turbine drive air to the bearing air i e with an air piloted valve Provisions should also be made to as sure bearing air remains on during the coast down period when turbine air is turned off See Specifications in the Introduction section
