The intended application is for general purpose radiographic equipment,
including tomographic and chest applications. Maximum tube rating must be 150
kV or less.
5. Installation:
Must be made with supplied hardware, including mounting flange, spacers (as

1.8 MAINTENANCE
The Collimator system must be properly maintained to assure both compliance with
BRH regulations and useful life.
Preventive maintenance is to be performed once every twelve months. This includes
inspection and lubrication of both the cassette tray(s) and collimator mechanism. The
collimator mounting ring and locking screw (70-10036 and 26-00752) should be
examined to ensure secure mounting of the collimator. ONLY PROGENY P/N
26-00752 COLLAR LOCKING SCREW SHOULD BE USED.
Checkout should also occur if any of the following conditions occur:
• Lamp replacement
• Premature electronic component failure
• When collimator is removed from tube/housing assembly
• When collimator and/or cassette tray have been subjected to external damage
Refer to Section 5.0 for collimator CHECK-OUT procedure, and refer to the cassette
tray manual for tray maintenance.
