receipt of the merchandise, any visible damage to the cartons should
immediately be examined while the shipper is present.
If the visible damage to the cartons also includes damage to the
merchandise, the installer is responsible for making all claims with the
shipping company.
If there is hidden damage to the merchandise, it is the installer's
responsibility to discover that damage within a reasonable amount of time
and contact the shipping company to make a claim.
To protect your company in the case of hidden damage it is recommended to
accept freight "subject to inspection". This makes it easier to make a claim
with the freight company in the event of hidden damage.

1.4 Safety
1.4.1 General
It is important that everyone associated with x-ray work is familiar with the
recommendations of the Department of Health, National Bureau of Standards, and
the National Council on Radiation Protection. The control of diagnostic medical x-
ray equipment varies in detail from state to state. However, in general, all of the
states adhere strictly to the established recommendations of the NCRP. Prior to
operation, be sure that all personnel who are authorized to operate the x-ray
system are familiar with the established regulations of the authorities named above.
Also, they should be monitored to assure that they conform to the
recommendations.
Current sources of information include:
•National Council on Radiation Protection Report No. 33 (Medical X-Ray
and Gamma-Ray Protection for Energies up to 10 MEV-Equipment Design
and Use).
•National Bureau of Standards Handbook No. 76 (Medical X-Ray Protection
up to Three Million Volts). Refer to MCRP Report No. 33.
•Current recommendations of the International Committee on Radiation
Protection.
Although x-ray radiation is hazardous, x-ray equipment does not pose any danger
when it is properly used. It is the responsibility of all service and operating
personnel to be properly informed on the hazards of radiation. Also, those
responsible for the system must understand the safety requirements for x-ray
operation. Study this manual and the manuals for each component in the system to
become aware of all the safety and operational requirements.

InnoVet Select
™ HF APR Service Manual
13
1.4.2 Manufacturer’s Responsibility
Although this equipment incorporates protection against x-ray radiation other than
the useful beam, practical design cannot provide complete protection. This
equipment does not prevent the possibility of improper use, which results in
authorized or unauthorized persons from carelessly, unwisely, or unknowingly
exposing themselves or others to direct or secondary radiation. Allow only
authorized, properly trained personnel to operate this equipment.
Be certain that all personnel authorized to use the equipment are aware of the
danger of excessive exposure to x-ray radiation.
This equipment is sold with the understanding that the manufacturer, its agents,
and representatives do not accept any responsibility for over-exposure of patients
or personnel to x-ray radiation. Furthermore, the manufacturer does not accept any
responsibility for over-exposure of patients or personnel to x-ray radiation
generated by this equipment which is a result of poor operating techniques or
procedures.
Also, no responsibility will be assumed for any machine that has not been serviced
and maintained in accordance with the system technical manual, or which has been
modified or tampered with in any way.
1.4.3 Radiation Protection
WARNING
X-Rays are dangerous to both operator and others in the vicinity unless
established safe exposure procedures are strictly observed.
The useful and scattered beams can produce serious, genetic or potentially
fatal bodily injuries to any persons in the surrounding area if used by an
unskilled operator. Adequate precautions must always be taken to avoid
exposure to the useful beam, as well as to leakage radiation from within the
source housing or to scattered radiation resulting from the passage of
radiation through matter.

InnoVet Select
™ HF APR Service Manual
14
Those authorized to operate, test, participate in or supervise the operation of
the equipment must be thoroughly familiar and comply completely with the
currently established safe exposure factors and procedures described in
publications such as Sub-Chapter J of Title 21 of the Code of Federal
Regulations, "Diagnostic x-ray Systems and their Major Components," and
the National Council on Radiation Protection (NCRP) No. 33, "Medical x-ray
and Gamma-Ray protection for energies up to 10 MeV-Equipment Design
and Use," as revised or replaced in the future.
Failure to observe these warnings may cause serious, genetic or potentially
fatal bodily injuries to the operator or those in the area.
Those working in the immediate area must protect themselves with lead shielding.
These items would include but not necessarily be limited to goggles, thyroid shield,
apron and gloves with a lead equivalency of not less than 0.5 mm.
The best safety rule for x-ray operators is:
“Avoid exposure to the primary beam at all times.”
1.4.4 Monitoring of Personnel
Monitoring of personnel to determine the amount of radiation to which they have
been exposed provides a valuable cross-check to determine whether or not safety
measures are adequate. The most effective method of determining whether or not
the existing protective measures are adequate is the use of instruments to measure
the exposure in Rads. This measurement should be taken at all locations where
the operator or any portion of his body may be during exposure.
A common method of determining whether personnel have been exposed to
excessive radiation is the use of film badges. These are x-ray sensitive film
enclosed in a badge which incorporates metal filters of varying degrees of
transparency to x-ray radiation. Even though this device only measures the
radiation, which reaches the area of the body on which it is worn, it does furnish an
indication of the amount of radiation received.

InnoVet Select
™ HF APR Service Manual
15
1.4.5 Electrical
WARNING
Failure to comply with the following may result in serious or potentially fatal
bodily injuries to the operator or those in the area.
Only properly trained and qualified personnel should be permitted access to
any internal parts of the x-ray system. Live electrical terminals may be
deadly; be sure line disconnect switches are opened and other appropriate
precautions are taken before opening access doors, removing enclosure
panels, or attaching accessories.
Do not remove the flexible high voltage cables from the x-ray tube housing or
high voltage transformer or the access covers from the generator until the
main and auxiliary power supplies have been disconnected.
When disconnecting high voltage cables, they must be grounded
immediately in order to dissipate any electrical charge that may remain on
the cables or the tube.
1.4.6 Mechanical
WARNING
Particular care should be taken when servicing the inside of the tubestand. There
is an extreme threat of mechanical pinching between the vertical slide and
counterweight due to their close proximity and opposite directions of motion.
All of the movable assemblies and parts of x-ray equipment should be operated
with care. Only properly trained and qualified personnel should be permitted
access to any internal parts of the x-ray system.

2.0 MECHANICAL ASSEMBLY
2.1 Radiographic Table
1. During shipment, the tabletop is banded to the table base. Cut loose the
banding and set the table top aside for assembly later. Loosen the hold-
down screws underneath the front rail of the table to release the grid cabinet.
Remove packing material from rear of grid cabinet.
2. Install the five leveling feet by threading them into the holes at the two front
corners of the table and at the ends and middle of the back rail. The two feet
with a 4" long body should be installed at the front corners of the table. The
three feet with a 1" long body should be installed at the back rail. (In the
accessory bag there are six blue and six red “U” shaped plastic spacers.
When leveling the table fully tighten the foot until the shoulder of the foot is
firmly against either these spacers or the bottom of the table/back rail). Use
of the spacers makes the table base/leveling feet union a solid “one piece”
structure, minimizing any wobble or table base motion.
Position the table close to its final location, using the leveling feet and
spacers to bring the table close to level at this time. Final leveling can be
done at end of assembly.
2.2 High Voltage Generator and Transformer placement
1. Verify that the oil level in the HV transformer is approximately 1/2" to 3/4"
below the underside of the cover. Refill with "Shell Diala oil AX" or remove
oil as necessary.
2. Using a piece of cardboard to protect the floor, push the transformer onto the
shelf in the table by tilting the transformer and sliding it up onto the right side
of the shelf. Once the transformer is in place, loosen the screw on the vent
plug to allow for oil expansion. Cover the vent plug and flange with one of
the loose fitting plastic covers provided with the HV transformer to prevent
contaminants from entering the oil.
3. Place the Power Module close to the front left side of the table but not inside,
leaving access on all sides. This allows the installer to establish the proper
wiring, routing and lengths for all cables.
