Scotsman Ac 86 Service Manual

[Eunice Beady]

Theseare the PDF operator manuals, service manuals, and miscellaneous items for some of the equipment that we service and install. The list is updated as we are able to find manuals for the equipment. Some of this equipment is obsolete and the manuals are hard to find. Please feel free to use this site as a free resource for your service and installation needs.

Cubelet ice and water dispenser, available in manual push button or touch-free options. Produces 70kg of ice every 24 hours with a 5Kg storage bin.

Ideal for hospitals and care homes, fast food restaurants and self-service applications.

The touch-free functionality makes them ideal for self-service applications as the operator simply places the glass beneath the spout to activate the machine. The enclosed storage bin keeps the ice away from contamination, making them a great choice for hospitals and care homes limiting points of contact which maintains maximum hygiene.

The ice thickness probe can be monitored on the controller LED for continuity. It is common for it to get false readings if the spray bar in not clean or you have a water filtration problem and high minerals. Also if any cleaning solution is left on it. The cleaner is a acid (phosphoric) and is very conductive. When cleaning the machine I always remove the sensor, scrub with a tooth brush, then rinse with a small amount of baking soda before drying and reinstall. Many guys will just change it out, but routing the wire is a bit difficult and more time consuming. Let alone the cost. But if it has a hairline crack, replacement will be necessary.

Pay especial attention to the spray bar and flow over the plate. It has to be even and slow. Often if someone has replaced the pump with a non OEM the capacity will be incorrect and make to aggressive a flow that will bother the sensor. Plugged holes or mineral buildup on the flow plate can also cause a problem.

Cleaning on them is a critical thing that small details mater. The service manual will give you a time period for the sensor to not be constant and to have a normal cycle for the freeze lockout. Make sure to read pg 42 on the sensor and spillway. Also make sure that the wire to the sensor is clean and dry. It can also conduct and fool the controller.

You will notice that when the machine goes into freeze cycle, and it has done the flush and continuity test it will pause the pump for 30 seconds. after that watch the harvest ready light. As water hits it it should flash a little and as the ice forms on the bridge the flashes will get longer. Once the LED stays on for 5 seconds solid it tells the machine to harvest. If it is happening too quickly you get the alarm. This means that the sensor is tricking a harvest under 6 min 3 times.

I should also mention that if the compressor discharge temp is to low, the controller will shut the fan off on air cooled models before entering harvest cycle. This is to ensure there is adequate heat for the hot gas harvest. The thermistor can be tested with a ohm meter for this.
