CU1526, CU2026, CU3030 User Manual Water The quality of the water supplied to the ice machine will have an impact on the time between cleanings and ultimately on the life of the product. Water can contain impurities either in suspension or in solution. Suspended solids can be filtered out. In solution or dissolved solids cannot be filtered, they must be diluted or treated. Water filters are recommended to remove suspended solids. Some filters have treatment in them for suspended solids.

CU1526, CU2026, CU3030 User Manual Ice Storage Bin Removal The ice storage bin is removable to allow access to 9. Remove two bolts from the bottom of the bin, one on the left and one on the right. the refrigeration system for service. 1. Remove front louvers. Remove left then right. 2. If the machine is in an ice making mode, push and release the Manual Harvest button to release any ice that might be on the evaporator. 3. Push and hold the controller's Off button to shut the machine off. 4.
CU1526, CU2026, CU3030 User Manual Plumbing Requirements Connect to cold, potable water. A hand actuated valve within site of the machine is required. Air cooled models have a single 3/8” male flare inlet water connection. Water cooled models have an additional 3/8” FPT condenser inlet water connection, and a 1/2" FPT condenser drain. 2. Connect drain tubing to drain fittings. Water Supply and Filters If connecting to water filtration, filter only the water to the reservoir, not to the condenser.
CU1526, CU2026, CU3030 User Manual Electrical The machine is supplied with a power cord. 208-230 volt, 60 Hz cords have NEMA 6-20P plugs. This is a cord-connected unit, and must be on a separate power supply. Check the dataplate for the voltage, ampacity and maximum fuse size and per the dataplate use fuses or HACR circuit breakers. Follow All Local Codes - This Unit Must Be Grounded. Do not use extension cords and do not disable or by-pass ground prong on electrical plug.
CU1526, CU2026, CU3030 User Manual Initial Start Up 1. Remove left front louver. Check machine for any packing or wires rubbing moving parts. Note location of control board at the left. 2. Switch the on off switch to On. 3. Switch on the electrical power to the machine. Observe that some of the control’s indicator lights glow and its display shows O. 4. Open the water supply valve.
CU1526, CU2026, CU3030 User Manual Adjustments Bridge Thickness - For the Service Tech Only 1/8-3/16" bridge 1. Remove left louver, locate controller on and off switches. 2. Push and hold Off till the machine stops. 3. Remove curtain. 4. Use a hex wrench and rotate the bridge thickness adjustment screw in 1/8 turn increments CW to increase bridge thickness. Rotate CCW to decrease bridge thickness. Caution: Do not make the bridge too thin or the machine will not harvest properly.
CU1526, CU2026, CU3030 User Manual Use and Operation Once started, the ice machine will automatically make ice until the curtain is held open by the ice at the top of the pile. The typical ice level when the machine is off will be several inches below the door sill. When ice level drops from use or meltage, the ice machine will resume making ice. If a small cluster of ice is holding the curtain open, open the curtain slightly to release it. The machine should resume making ice in a few minutes.
CU1526, CU2026, CU3030 User Manual Control Switches There is a front on and off switch, located in the top center of the louvers. Switching this switch Off will immediately stop the machine. Switching it back on will cause the machine to restart in a timed harvest cycle. When that cycle is complete, normal ice making will resume. Ice The cuber drops ice in large sections. That ice will break up into random parts as it falls into the bin, but some large sections may remain on top of the ice in the bin.
CU1526, CU2026, CU3030 User Manual Cleaning, Sanitation and Maintenance This ice system requires three types of maintenance: • Remove the build up of mineral scale from the ice machine’s water system and sensors. • Sanitize the ice machine’s water system and the ice storage bin. • Clean or replace the air filter and clean the air cooled condenser (air cooled models only). It is the User’s responsibility to keep the ice machine and ice storage bin in a sanitary condition.
CU1526, CU2026, CU3030 User Manual 23. Push and release the On button to resume ice making. 24. Return the top panel and front louvered panel to their normal position and secure with the original fasteners. Air cooled condenser filter Inspect Orifice Holes 1. Remove left front grill . Inspect Water Distributor 2. Wash the dust and grease off the filter. 14. Locate ice thickness sensor. Squeeze mounting legs together to release sensor.
CU1526, CU2026, CU3030 User Manual What to do before calling for service Reasons the machine might shut itself off: • • • • • To Manually Reset the machine. • Push and release the Off button. • Push and release the On button.
