Atosa Under-counter Ice Machine Installation

Comprehensive Guide to Installing the Atosa YR140-161 and YR280-AP-161 Under-Counter Ice Machines

Installing an under-counter ice machine can be a straightforward process if you follow the necessary steps and guidelines. In this guide, we will walk you through the installation process for the Atosa YR140-161 and YR280-161 ice machines, ensuring that you can set up your unit efficiently and correctly. Let's dive in!

Pre-Installation Requirements

Before you begin the installation, it's crucial to prepare the setup area and ensure you have all necessary components and tools. Here are the prerequisites: It is essential to avoid installing the drain line uphill as this can lead to standing water in the bottom of the ice bin.

Connecting the Drain Hose

Start the installation process by connecting the provided drain hose to the drain port on the back of the ice maker:

• Push the rubber end of the hose over the hose barb.
• Secure it with the included zip ties.

Connecting the Water Line

The next step involves connecting the water line to the ice machine. The water inlet on the ice machine features a push-to-connect fitting:

• Push the water line into the push-to-connect fitting.
• Secure it with the blue retaining clip to ensure a tight connection.

Powering the Ice Machine

Once the water and drain lines are connected, plug the ice machine into the power outlet to begin the initial setup and adjustments.

Initial Startup and Adjustments

With the connections in place, it's time to start the ice machine and make necessary adjustments for optimal performance.

Removing the Top Cover

To access the internal components for adjustments, follow these steps:

• Remove the top two screws on the back of the ice maker.
• Slide the top cover to the rear and lift it off.

Adjusting Ice Thickness

After the top cover is removed, power on the ice maker and wait for it to drop a batch of ice. Check the ice for bridge thickness, which is the ice thickness between the cubes. Ideally, this should be around 1/8 of an inch:

• If the bridge thickness is greater (e.g., 1/4 inch), adjust the Harvest probe to thin out the ice bridge.
• The Harvest probe is located on the right side of the ice plate and is characterized by a red wire.
• Loosen the top plastic nut on the probe.
• Turn the lower plastic nut clockwise to raise the probe (thinning the bridge) or counterclockwise to lower it (thickening the bridge).
• Retighten the top nut to secure the probe in place.

Allow the ice maker to produce another batch of ice and verify the bridge thickness. Repeat adjustments as needed until the desired thickness is achieved.

Adjusting Drain Time

Proper drain time is crucial for preventing cloudy ice and maintaining machine cleanliness. Follow these steps to adjust the drain time:

• Remove the two screws holding the bottom blue vent cover in place and remove the cover.
• Locate the metal box behind the vent cover, which houses the control board.
• Remove the two screws holding the cover of the metal box and take off the cover.
• Inside, find the small blue box (potentiometer) with a screw in the center on the control board.
• Use a small screwdriver to adjust the screw: turning it 1/8 of a turn clockwise adds approximately 10 seconds to the drain time, while counterclockwise removes 10 seconds.

Allow the ice maker to produce another batch, observing the drain process to ensure all water is expelled before the Harvest cycle. Adjust as necessary.

Finalizing Installation

Once the adjustments are complete and the ice machine is functioning correctly, replace all panels and covers securely. This marks the end of the installation process, and your ice machine should now be ready for use.

Thank you for following this detailed installation guide for the YR140-161 and YR280-161 under-counter ice machines. With proper setup and adjustments, your ice machine will provide efficient and reliable service.
