Chapter 1

6
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 operator. Read and
understand all operating and service procedures before attempting to operate the reprocessor.
Intended Use
The DSD-201 Endoscope Reprocessor is intended to be used to wash, high-level disinfect and rinse
endoscopes and related accessories between uses. It is intended to be used with a legally marketed high-
level disinfectant solution. It can also be used to leak test endoscopes if equipped with the leak test
capability.
Only properly trained individuals may operate or service the reprocessor. Never use the reprocessor for
any purpose other than the manufacturer’s specic 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 oating basin lid during operation.
For disinfectant handling guidelines, refer to the American National Standard recommended practice
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.

7
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 appropriate 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 disinfection 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-ltered to minimum of 0.45-microns.
• The high performance 0.2-micron water lter included with the reprocessor is a sterilizing grade
bioretentive lter. The lter removes all microorganisms and particles greater than 0.2-microns.
• The routine maintenance schedule recommends replacing the 0.2-micron water lter every 6 months
or sooner, depending on the pre-ltration system and the quality of the incoming water.
• Incoming water supply (upstream of the external pre-ltration system) should be shut-off at the end
of every work day.

8
Detergent Solution
If the user decides to inorporate a pre-wash in the reprocessing cycle MEDIVATORS recommends the use
of a detergent solution that has bacteriostatic properties to inhibit bacterial growth in the detergent reservoir
and detergent line. The detergent should be low foaming and free-rinsing neutral in pH recirculation.
Caution! Never use household detergent in the reprocessor.
Disinfectant Solution
Select a low-foaming, high level disinfectant specically 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 programming the
disinfection cycle.
Monitoring Disinfectant Potency
High Level Disinfectant (HLD) testing must be performed before each reprocessing cycle. The minimum
required concentration (MRC) testing of the high level disinfectant (HLD), ensures the HLD is at an
effective level of potency, so that it can be used to disinfect an endoscope or medical device. Testing the
potency prior to starting a reprocessing cycle, conrms the disinfectant’s MRC potency, and that it can be
used to achieve high level disinfection of an endoscope or medical device.
Use only the disinfectant manufacturer’s recommended test strips to test the potency of the HLD. If the
high level disinfectant is below the minimum required concentration, then discard the used disinfectant
and replace it with new disinfectant, prior to initiating a reprocessing cycle. Refer to the test strip
manufacturer’s instructions, for further details and step-by-step use instructions.

9
Endoscope Precleaning and Testing
All endoscopes must be precleaned prior to disinfection. Follow the endoscope manufacturer instructions
and established professional guidelines to properly preclean the endoscope.
• Endoscopes with elevator wire channels require additional manual cleaning and
disinfection steps.
• Leak test endoscopes prior to disinfection procedures.
Cleaning and Disinfection
Always follow established professional guidelines while cleaning and disinfecting endoscopes.

INSTALLATION
General
Move the reporcessor 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 procedure in
the Maintenance chapter.

System Supply
Water Supply
For optimum cycle performance, the water supplied to the reprocessor must provide a ow rate of 3.2 gal/min (12 liters/
min), at 35-40 psi (2.4-2.75 bar). The incoming water line must be a minimum 1/2-inch (13 mm). Use a cold water
supply with a maximum temperature of 110° F (43° C).
1. Install an incoming water shut-off valve before the pre-lter system.
2. Install the incoming water prelter, supplied with the reprocessor.
• Mount the incoming water lter on the wall where it can be periodically checked for
particle saturation.
Note: The lter is provided with the outlet on the right side. If the lter installation
requires the outlet to be on the left side, remove the ltration brackets and reinstall
on the opposite side, then loosen and rotate the gauges 180°.
3. Install the supplied water regulator between the pre-lter and the reprocessor water connection.
• Incoming water pressure to the regulator must be less than 100 psi (6.8 bar).
• Set the outgoing water pressure between 35-40 psi (2.4-2.75 bar).
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.
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 tting on the side of the cabinet.
Warning! This air must be supplied from an oil free air source.

13
System Drain
The drain tube provided with the reprocessor consists of 36 inches of 1-inch diameter clear tub- ing. The drain tube
must have 3 inches of drop (7.5 cm) or greater over the 36-inch length. Con- sult your maintenance department for
multiple reprocessor installation.
Caution! The reprocessor drain relies on gravity ow. There must
be no low spots in the drain line. Fluid trapped in the drain line will
interfere with free drainage and reprocessor function.
Installation Verication
To be sure that the system is ready to operate, perform a trial run with water as outlined below. Use scope hook-up to
simulate an endoscope.
Caution! Operating the 120VAC reprocessor without a hook-up
tting might blow the 8-amp slow blow fuse. Operating the 230VAC
reprocessor without a hook-up tting might blow the 4-amp slow
blow fuse.
1. Load the lower reservoir with water. Use the procedure described in the Operator Con- trols Chapter for
loading disinfectant.
2. Fill the alcohol and detergent reservoirs, then prime the tubing.
• Enter the Custom Programs menu.
• Set the alcohol and detergent inject time to 15 seconds.
3. Close the lid, then press the START button.
4. Check the ow through the tubing during the disinfect, air, and rinse cycles.
5. Check the water regulator in the incoming water line.
• Pressure must be 35 - 40 psi (2.4 – 2.75 bar).
6. Verify the cycle completes with no errors.
7. Verify there are no leaks in the reprocessor.
8. Press DISINFECT DUMP and START on the control panel to run a dump cycle. Refer to the “Disinfection
Dump” procedure in the Operation Chapter of this manual
9. After the disinfectant dump cycle is complete, program the disinfectant soak, etc., times as needed.
10. Load fresh disinfectant and begin to operate the reprocessor.
Service: If the reprocessor cannot be veried, contact MEDIVATORS
