INTRODUCTION

CAUTION: KEEP THIS INFORMATION WITH THE TUBE UNTIL INSTALLED ON EQUIPMENT.
Consult the equipment manufacturer's instructions to install, test, calibrate or service this tube assembly.
A. This device is intended for use in a controlled environment and can be energized immediately after installation. The limits
of the controlled environment are defined in the accompanying documents.
B. Nominal and Maximum voltages are considered the same value for X-Ray Tube Housing Assemblies.
C. Upon receipt of the unit, inspect for damage or breakage. If any damage is noted, report to the carrier by filing a written
report. Retain shipping container for use when returning the unit for insert replacement or other reasons.
D. The following information is applicable to conventional four-valve, single phase, 6 or 12 pulse, three phase or DC
power supply.
1.1.

MOUNTING

A. All Varian X-ray products have provisions for mounting the unit on OEM equipment. These include trunnion mounting,
port plate mounting or by threaded holes in bosses designed for the application. Mount the X-ray product only according
to the OEM's procedure. Some applications position the X-ray tube assemblies and accessories over a patient. Varian
recommends that all mounting threaded connectors be traceable as directed by NIST, under authority delegated by the
Secretary of Commerce, and pursuant to Section 15 of the Fastener Quality Act, (Pub. L. 101- 592 as amended by
Pub. L. 104- 113).
B. Tubes that are mounted by means of the port boss may have an intermediate plate between the port boss and beam limiting
device. This plate can be used as one of the spacers necessary to mount the beam limiting device. Steel spacers are
supplied with beam limiting devices. If the mounting plate is not made of steel but of a lighter metal such as aluminum,
the hole in the aluminum plate must be lined with a minimum of 1 mm of lead.
C. Mounting instructions are supplied with each beam limiting device that has been certified as compatible with a specific
tube housing assembly. These instructions must be followed carefully in order to meet the inherent filtration requirements
of the diagnostic source assembly.
D. The tube housing assembly is connected to the grounding circuit with a green/yellow wire supplied for grounding
purposes.
E. Apply this product to only systems that have earth grounding.
1.2 INSTALLING THE HIGH VOLTAGE (HV) CABLES
CAUTION: Refer to HV cable installation procedure provided with the tube or HV cable for proper installation. Refer to
product data sheet for operational data and wiring diagrams.
A. Clean cable terminal and receptacle. Be sure rubber compression gasket is in place, if required.
B. Apply thin coat of vapor-proofing compound to the entire surface of the cable terminal insulator using a clean dry
applicator. Fully cover the end of the insulator and taper the vapor-proofing compound from pin tips to the end of the
insulator, removing all air around pins.
C. Engage contact pins in socket insulator; tighten cable nut. Retighten after calibration.
D. In the event of high voltage cable failure, Varian recommends replacement of high voltage cables and not re-termination.
