This video shows the installation and operation of the Ultra Clean Systems Models XL-48 and XL-72. It also demonstrates how to change the filter for these systems.

XL-72 – Transcript

The following tools will be needed during the installation of your Ultra Clean Systems XL-72. You will need small channel locks, small crescent wrench, Phillips head screwdriver, nut driver bit, large channel locks and some snips.

During this video, we will demonstrate the installation of the following parts: Hot water hose, cold water hose, enzyme stick and hose, air hose, drain hose, and an optional deionized rinse water hose.


When installing hoses, use plumbers tape on all threaded connections.

The airline hose should be installed first. For new machines shipped from the manufacturer, this hose should be located in the top tray towards the front of the machine.

After applying plumbers tape to the threaded end, inset into this fitting. Rotate the hose clockwise until snug. Using a crescent wrench, tighten until snug, but do not over-tighten.  After the connection is made, turn on the air supply and the basket carriages should rise to the up position.

Next, install the hot water hose by inserting the threaded end into this connection. Rotate the hose until it starts to snug. Then using the crescent wrench, tighten until snug but do no over-tighten.

Next, after applying plumbers tape, install the cold water hose similarly to the hot water hose. Rotate the hose until it starts to snug. Then using the crescent wrench, tighten until snug but do no over-tighten.

The drain line is installed by pushing the hose onto this connection. Then slide the hose clamp up the hose and over the fitting. Using the nut driver, tighten the clamp until it is secure.

Next, we will install the enzyme hose and stick.  This is the enzyme port… this is the filter… and this in the extension tube. After removing all zip ties, insert either end of the enzyme hose into the stick until you hear it click into position.  Then insert the other end of the hose into the enzyme port until you see the release tab spring up indicating a good connection.  This configuration is for use with 5 gallons of enzyme.  When using 15 gallons of enzyme, you will need to install the extension stick.  Simply unscrew the port from the end of the stick, screw the extension into the stick, and thread the port into the newly added extension.  Then insert the enzyme hose into the port and you are ready for 15 gallons of enzyme.

Your XL-72 comes from the factory with the DI/RO rinse port (de-ionized or reverse osmosis) connected to the cold water connection.  If you prefer to connect to your DI/RO water source, remove the jumper hose that is currently connected and install the supplied hose. Insert the quick connector into the port on your machine, and connect the other end of the hose to your DI/RO source. Once all of your hose connections are installed, you are ready to attach the power cord. Simply inset the female end of the cord into the power connector on the machine, and plug the other end into you power outlet


To log in to your system, press the “Enter Code” box on the screen. A number pad will be displayed where you should then enter your identification/login code and press “Enter.”  The default login code is 9-7-1-3.  After the login code has been entered, the status bar should change to “Authorized.” Then press the “Log on” button.

Once you are logged in, the operations control panel is displayed.  Notice how the graphics represent the basins and the baskets of your machine.  The XL-72 has a basin with 3 baskets on the left, and a basin with three baskets on the right. Each basin is fully independent of the other, so they can be used together or separately.

Before you start a cycle, you have three options for each basket. You can choose “Lumen Basket”, “Hospital Basket”, or leave it in “Ready” if that particular basket is not being used during that cycle.

Note:  To save time, water and enzyme, always fill the lower baskets first, then work your way up.  If you load the top basket only and then run the cycle, the machine will fill completely with water and use more enzyme unnecessarily. The time to fill and drain the machine will also take longer.

Different instruments require different minimum cycle times as recommended by their manufacturer. When combining multiple instruments with varying recommended cycle times, use the longest recommended time for that load. For instance, if you have three instruments to clean, and two of the instruments require 8 minutes, and one instrument requires 13 minutes, set the time to 13 minutes. To change the cycle time, simply press the timer box to bring up the number pad, enter the new time value and press “Enter.”

Once you are ready to begin a cycle, press “Start” at the bottom of the screen.

Note:   To avoid injury and damage to your machine, always remember to keep hands and other items clear of the baskets as they are lowered into the basin.

When you press “Start”, notice the graphics on the display as the carriage is lowered into the basin.  You are notified that the carriage is moving, water is filling the basin, and the cycle is running.  When the cycle is complete, the carriage will raise the baskets and the display will show “Clean.”

To check the level of your detergent, or to add more detergent, select the detergent button at the top of your screen.  The left side of the display shows the level of detergent, and the right side allows you to transfer detergent, when needed. Select “Back to Operations” to get back to the main screen.

Main Menu
To enter the main menu from the operations screen, select “Menu” at the top of the screen.  From this menu, you have access to many settings.

All of the cycle times for the XL-72 are controlled from the “Timers” menu.  Here you have access to rinse times, drain times, maximum fill times, air purge times and more.  Most values in this menu are in seconds, except “Detergent Volume Calibration” uses sliding scale values from 1 to 10, and “Minimum Sonic Power” is a percentage.
–   Cycle Drain Times should be 120 seconds.
–    Minimum Sonic Power should be left at 70%.
