Operation outside the limits listed here will void the warranty. Air temperature limits Ice maker Remote condenser Minimum 50oF. -20oF. Water temperature limits Maximum 100oF. 120oF. 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 dissolved solids. Check with a water treatment service for a recommendation. All models Minimum 40oF. Water pressure limits (potable) Maximum 100oF. All models Maximum 20 psi Minimum 80 psi Water pressure limit to water cooled condenser is 150 PSI RO water. This machine can be supplied with Reverse Osmosis water, but the water conductivity must be no less than 10 microSiemens/cm. Potential for Airborne Contamination Installing an ice machine near a source of yeast or similar material can result in the need for more frequent sanitation cleanings due to the tendency of these materials to contaminate the machine. Voltage limits Minimum 115 volt 104 208-230 60 Hz 198 Minimum conductivity (RO water) Maximum 126 253 Most water filters remove chlorine from the water supply to the machine which contributes to this situation. Testing has shown that using a filter that does not remove chlorine, such as the Scotsman Aqua Patrol, will greatly improve this situation.

Check for hidden freight damage, notify the carrier immediately if any is found. Retain the carton for the carrier's inspection. Panel Removal The machine is not bolted to the skid. If strapped remove the strap. Place on Bin or Dispenser If reusing an existing bin, be sure that the bin is in good shape and that the gasket tape on the top is not torn up. Water leaks, not covered by warranty, could result from a poor sealing surface. If installing a remote or a remote low side, a new bin is recommended due to the high cost to the user of replacing an old bin when a remote system is on top. Install the correct adapter, following the directions supplied with that adapter. Hoist the machine onto the adapter. Note: The machine is heavy! Use of a mechanical lift is recommended. Position the machine on the bin or adapter. Secure with straps from the hardware bag packed with the machine, or those supplied with the adapter. Remove any plastic covering the stainless steel panels. 1. Locate and loosen the two screws at the bottom of the front panel. 2. Pull the front panel out at the bottom until it clears. Remove any packaging, such as tape or foam blocks, that may be near the gear reducer or ice chute. Level the bin and ice machine front to back and left to right by using the bin leg levelers. 3. Lower the front panel down and off the machine. 4. Remove two screws at the front of the top panel. Lift up the front of the top panel, push the top panel back an inch, then lift to remove. 5. Locate and loosen the screw holding each side panel to the base. Left side panel also has a screw holding it to the control box. 6. Pull the side panel forward to release it from the back panel.

Calculation Formula: · Route a line set that rises, then falls, then rises. · Route a line set that falls, then rises, then falls. Calculation Example 1: The condenser is to be located 5 feet below the ice machine and then 20 feet away horizontally. 5 feet x 6.6 = 33. 33 + 20 = 53. This location would be acceptable · Drop = dd x 6.6 (dd = distance in feet) Calculation Example 2: · Rise = rd x 1.7 (rd = distance in feet) · Horizontal Run = hd x 1 (hd = distance in feet) · Calculation: Drop(s) + Rise(s) + Horizontal The condenser is to be located 35 feet above and then 100 feet away horizontally. 35 x 1.7 = 59.5. 59.5 +100 = 159.5. 159.5 is greater than the 150 maximum and is NOT acceptable. · Run = dd+rd+hd = Calculated Line Length Operating a machine with an unacceptable configuration is misuse and will void the warranty. 40h.d35" rd Max 35 feet Remote Condenser located above ice machine.

When this option is present there is an adjustment post and an additional indicator light to the right of the four indicator lights mentioned earlier. There are several positions the ice level can be set to, including Off or Max (knob and label indicators lined up), where it fills the bin until the standard bin control shuts the machine off. See the kit's instructions for complete details including special instructions for dispenser applications. The ultrasonic ice level control allows the user to control the point that the ice machine will stop making ice before the bin or dispenser is full. Reasons for this include: · Seasonal changes in ice used · Planning to sanitize the bin · Faster turnover for fresher ice · Certain dispenser applications where maximum ice level is not desired Rotate the adjustment post to the desired ice level. The machine will fill up to that level and when it shuts off the indicator light next to the adjustment post will be On. Note: The maximum fill position is when the arrow on the knob points to the arrow on the label.
