WARNINGS Dangerous voltages exist within the injection system that can shock,
burn, or cause death. To avoid injury, the system should be opened and
serviced by qualified service personnel only. Disconnect the system from
line power before cleaning or attempting to perform any maintenance or
repairs.
Mains Voltage Hazard. To avoid dangerous voltages, do not remove con-
nector J130 while power is applied to the system. Always disconnect the
system from line power before removing connector J130
Live Voltage Hazard. Avoid contact with J40 pins. Ensure that the connec-
tor cover is in place or cable is connected.
Possible explosion hazard in the presence of flammable anesthetic
gases. The injection system is not designed for use in association with
anesthetic gases and equipment.
Electronic assemblies contain potentially hazardous materials. Dis-
pose of system components or accessories properly. Follow all local regu-
lations for the recycling or disposal of electronic assemblies, or contact
MEDRAD Service for assistance.
Worn power cords or control cables may shock, injure, or cause
death. Examine power cords and cables for cuts, frays, or any other visible
damage. Do not use the system if any of the cords or cables show signs of
damage. Any damaged or worn connection cables or power cords should
be replaced.
Check for proper voltage and frequency before connecting the injec-
tor to an electrical outlet. Failure to do so may result in personal injury or
equipment damage/malfunction. Check the voltage and frequency marked
on the back of the unit. Ensure that the outlet providing power to the injector
supplies a voltage, frequency, and volt-ampere rating within the range
specified.
Do not use an extension cord or power cord adaptor. Connect the
injector directly into a properly grounded AC outlet. Since the power cord
supplies a safety ground to the unit, using an extension cord will compro-
mise ground quality and the injector could become unsafe.
Do not immerse any injector components in water or any type of
cleaning solution. Fluid entry may result in a shock hazard.
Ensure that FluiDot labels are clearly visible on all pressure jackets.
FluiDot labels are intended to help in the avoidance of air embolization,
which could result in patient injury or death.
Injury may result from springing action when injector head is
removed from the arm. Move the arm to the maximum upright position
before removing the injector head. When re-mounting the injector head,
ensure that the retention knob is secured to prevent the injector head from
falling from the arm.

Injury may result if excessive weight is applied to the device. Do not
place heavy objects or lean on the arm, injector head, or handles.
Injury may result during the transport of the injection system. Care
should be taken when transporting the injector. Ensure that the articulat-
ing arm is secured by inserting the locking pin.
Pinch Hazard. Do not grasp any pivot points. Position the injector head
by grasping the arm or extension.
CAUTIONS Electrostatic Discharge (ESD). Failure to follow ESD protection prac-
tices may result in equipment damage. To avoid damage, ESD protection
practices must be followed when servicing any component of this system.
If electronic components are to be shipped, place the components in con-
ductive carriers (as supplied at MEDRAD).
Disconnect the power cord before removing or replacing PC
boards. Sensitive circuits on the boards can be damaged by abrupt inter-
ruption or application of supplies.
Remove power when disconnecting or reconnecting head cables.
Disconnecting the head cable from the injector pedestal, or head exten-
sion cable from the rack or table mounts, when power is applied, may
result in equipment damage.
Allow system temperature to stabilize before use. When the system
is exposed to an extreme temperature change (heat or cold), allow it to
stabilize to room temperature before servicing.
Use only accessories and options designed specifically for the
Mark V ProVis injection system. To ensure compatibility and proper
operation, do not use an accessory or option designed for another sys-
tem.
Perform regular preventive maintenance. To ensure that your injection
system remains properly calibrated, and that all primary and backup cir-
cuits are functioning properly, regular preventive maintenance is recom-
mended. An annual preventive maintenance package (offered in the
U.S.A., Canada, and Europe) is available at an additional cost. Contact
your local MEDRAD Factory Service Representative for details.
Do not soak or immerse any part of the injection system in water.
Improper or careless cleaning methods may result in equipment damage.
While cleaning any outside portion of the system, avoid allowing any
water to seep inside system components.
Do not short the PPI Card Batteries. Do not place the card or the bat-
teries on any conductive surface. When checking or replacing the PPI
card batteries, discharge can occur with even a momentary short.

Do not apply voltage to ISI connector J40 pins 5,6,7,8 or 9. Equip-
ment damage or malfunction may result.
Do not move the injector or pedestal by pulling on the syringe
heater cable. Equipment damage or malfunction may result.Do not
connect injector head extension cables in parallel. Connecting the
extension cables in parallel, or extending the total extension length
beyond 100 feet (30.5 m), can adversely effect injector performance and
specifications.
NOTE: All relevant institutional, local, or national safety regula-
tions related to cable routing and installation should be
followed.
Do not apply voltage to external start lines if the injector is being
started by an external start connection. Provide only a switch closure.
If the external circuit contains excessive line frequency noise or voltage
transients, injector damage or malfunction may result.
The Remote Start Signal from the film changer programmer (at pins
7 and 9 of J40), must never contain voltage or AC noise. Any voltage
applied to these pins can damage the injector and void the warranty.
Excess noise on these lines may cause intermittent problems of prema-
ture, or no injections.
The Remote Start Signal from the film changer programmer must
remain closed throughout the duration of the injection. If the start
signal is removed before the injection volume limits when armed in the
SINGLE mode, the injection will stop, the unit will disarm, and display
“PREMATURE TERMINATION” on the Control Panel. If the start signal
is removed before the injection volume limits when armed in the MULTI-
ple mode, the injection will stop, the Mechanical Stop will reposition at
the selected volume, and the unit will remain armed. If a start signal is
received at this time, an additional injection will result at the selected
Flow Rate and Volume.
When starting the injection process from a remote location by the
use of a relay closure in the film changer programmer, always
install a “panic button” in series with the start signal. This function
must be provided in the event that the operator must immediately termi-
nate the injection. This button should be installed in a convenient loca-
tion, properly labeled, and instructions for use provided to all users of the
injection system.

Preventive
Maintenance
This section contains recommended procedures for preventive main-
tenance of injection systems. Routine maintenance and inspection
will:
• Ensure the continued performance of your injector.
• Reduce the possibility of equipment malfunction.
Recommended
Procedures
Preventive maintenance of the injection system should consist of four
procedures: Inspection, cleaning, leakage, and performance checks.
This section contains guidelines, recommended methods, and
expected results for each of these procedures:
1. Inspection: This first step should encompass inspection of the
entire system, looking for obvious signs of damage, such as;
cracks in the housing, frayed or worn cables, missing or damaged
labels, and contrast spills that may have leaked into the injector.
2. Cleaning: This cleaning procedure involves thorough cleaning of
the console and head to remove any deposits of contrast medium.
If any substances have leaked into any part of the unit, the subas-
sembly should be disassembled and thoroughly cleaned.
3. Electrical Leakage / Ground Continuity Checks: To ensure the
safety of the patient and hospital personnel in injector operations.
4. Operational Checkout: A complete functional performance check-
out of the injection system.

Recommended
Schedule
The injection system must be properly maintained to ensure that it is
in peak operating condition. Your individual maintenance schedule
depends upon how your injector is used; the type of procedures per-
formed, and frequency of use. The following guidelines represent a
suggested maintenance schedule:
Daily:
Before use each day, the system should be inspected, and the injector
head piston rod thoroughly cleaned.
Monthly:
Once a month, the entire system should be thoroughly inspected and
cleaned, and an operational checkout should be performed.
Annually:
Once per year, Electrical Leakage and Ground Continuity checks
should be performed.
NOTE: Local regulations or hospital protocol may require elec-
trical leakage checks at more frequent intervals. If this
applies, local regulations for leakage must be followed.
MEDRAD also recommends that a complete system calibration and
performance checkout, by a qualified MEDRAD Service Representa-
tive, be performed once a year. Contact MEDRAD Factory Service, or
your local MEDRAD office for details.
In the United States, Canada, Europe, and other select areas of the
world, the MEDRAD Service Department offers Preventive Mainte-
nance Programs. These annual programs greatly assist in maintaining
accuracy and reliability, and can extend the life of the injection system.
Contact MEDRAD for details. In Europe, contact MEDRAD Europe
B.V., or your local authorized dealer, for further information. Refer to
Section 2 of this manual for address and telephone numbers.
NOTE: Failures which occur due to lack of proper mainte-
nance, or abuse, will not be covered under warranty.
