Safety
This section outlines general safety guidelines for proper operation and service of the reprocessor.
Failure to follow these guidelines may result in severe injury or death to the patient and/or opera-
tor. Read and understand all operating and service procedures before attempting to operate the
reprocessor.
Intended Use
Only properly trained individuals may operate or service the reprocessor. Never use the reproces-
sor for any purpose other than the manufacturer’s specific intended purpose.
Operator Safety
Avoid biological contamination and chemical burns—always wear appropriate personal protective
equipment when handling endoscopes or disinfectant solutions. Never open the reprocessor lid or
remove the floating basin lid during operation.
For disinfectant handling guidelines, refer to the American National Standard recommended prac-
tice titled “Safe Use and Handling of Glutaraldehyde-based Products in Health Care Facilities”
(AAMI/FDS ST58, 1996-03-26). The document is available from the Association for the
Advancement of Medical Instrumentation.

INTRODUCTION
Guidelines
Guidelines are established to ensure patient safety, operator safety, and to maintain reliable
reprocessor operation.
Installation and Maintenance
Proper maintenance will ensure effective disinfection and prolong the life of the reprocessor.
・ The reprocessor must be protectively grounded.
* The system default is factory-set for a 20 minute disinfectant immersion period. This
period may be changed in the custom program setting. Verify the program is appro-
priate for the disinfectant used.
+ All pressure regulators are factory-preset. Do not adjust the settings. Contact your
Technical Support representative for assistance.
・ Do not allow the sanitizing solution to contact metal components.
* Do not use alcohol or alcohol-based products to clean the reprocessor cabinet as this
may cause crazing.
+ The hook-ups are not autoclavable and must be reprocessed by low temperature dis-
infection only.
・ Replacement parts must be ordered from the manufacturer to maintain the warranty.
Water Quality
Potable water is the minimum standard. Incoming water must be pre-filtered to minimum of
0.45-microns.
* The high performance 0.2-micron water filter included with the reprocessor is a ster-
ilizing grade bioretentive filter. The filter removes all microorganisms and particles
greater than 0.2-microns.
+ The routine maintenance schedule recommends replacing the 0.2-micron water filter
every 6 months or sooner, depending on the pre-filtration system and the quality of
the incoming water.

REPROCESSING SYSTEMS
Detergent Solution
Medivators recommends the use of a detergent solution that has bacteriostatic properties to inhibit
bacterial growth in the detergent reservoir and detergent line.
Caution! Never use household detergent in the reprocessor.
Disinfectant Solution
Select a low-foaming, high level disinfectant specifically manufactured for high-level medical
instrument disinfection. The product must be capable of destroying M. tuberculosis.
・ Consult the product label for appropriate contact time and temperature when program-
ming the disinfection cycle.
Monitoring Disinfectant Potency
The efficacy of a disinfection procedure is directly related to the disinfectant solution used and the
amount of time the endoscope is exposed to that solution.
・ Disinfectants must be monitored for potency on a daily basis. Consult the disinfectant
manufacturer recommendations for monitoring guidelines.
* Use the manufacturer’s test strips to test the potency of the solution on a daily basis. If
the potency of the solution is below its minimum recommended concentration (MRC),
discard and replace it with fresh solution.
* Never use disinfectant beyond the manufacturer’s recommended reuse life, even if the
potency levels are acceptable.
+ Never use disinfectant with unacceptable potency levels, even if the reuse date is
unexpired.

INSTALLATION
General
Move the reprocessor to the installation location before removing the protective packaging
material. If this is not possible, use a hand truck or moving dolly and ensure the reprocessor is
not damaged.
During installation, be sure the lower reservoir cover is in place, to prevent drill shavings and
chips or other debris from entering the reservoir.
The reprocessor must be installed on a level surface, or adjusted to level. See the Leveling pro-
cedure in the Maintenance chapter.

REPROCESSING SYSTEMS
Electrical Supply
Domestic reprocessors are supplied with a hospital grade, grounding plug that can be connected to
any standard 110-130VAC outlet. International reprocessors are supplied with a standard ground-
ing European plug that connects to 220-240VAC outlets.
We recommend surge protectors be used for protection against power spikes and surges. The
reprocessor must be plugged into or connected to a fused branched circuit.
Caution! The reprocessor does not have an on/off switch. Be sure
the reprocessor is positioned so that the power cord or
main circuit breaker is accessible at all times.
Warning! The reprocessor must be protectively grounded.
ας
Air Supply
Compressed air is required (30 - 60 psi/2.1 - 4.1 bar). If you did not purchase the air compressor
option with the reprocessor, be sure to make the compressed air connection to the labeled fitting
on the side of the cabinet.
Warning! This air must be supplied from an oil free air source.
