Pre-Installation
Other Applications:
Check Scotsman sales information for recommendations regarding applications.
Do not place Air Cooled models where the noise from the fan will be objectionable.
Check the nameplate for electrical requirements. The nameplate is located on the back of the ice machine. While the model and serial number are on the nameplate, a serial number plate is located at the front of the machine, near the purge valve.
Water:
There is no such thing as pure water. All water contains some impurities. There are two ways water carries the impurities: suspended and dissolved. Suspended solids can be filtered out. Dissolved solids must be diluted or treated. Water filters are recommended to remove suspended solids. Some filters also have treatment in them for dissolved solids. Check with a water treatment service for a recommendation.
Cube Ice machines use more water than what ends up in the bin as ice. While most water is used during ice making, a portion is designed to “rinse" out the water system to keep hard water scale from clogging up the machine. That water rinse, combined with water filters, prolongs the times between needed water system cleaning.
Note: All Scotsman CM described in this manual, feature Scotsman’s AutoIQ™ control system and ReliaClean™ water system cleaning process.

Note: Slope front bins must have an internal baffle. Scotsman HTB555 and BH550 have the required baffle. Baffle must be approximately in the position shown in the diagram.

Service Technicians: All models covered here come set from the factory at a “standard” water rinse, which is compatible with typical water conditions. They may be adjusted to “Minimum" or “Maximum" water rinse after start up. If the prior ice machine worked acceptably well with the local water conditions, leave the machine at the factory setting. If severe water conditions are present, and water filters do not solve the problem acceptably, adjust the machine to use more water. If water conditions are excellent, adjust the machine to use less water. See the Adjustments section.
Note: Water use adjustments are customer convenience adjustments; they are NOT factory defects and are NOT covered by warranty.

Location & Assembly
Air cooled models take room temperature air in from the sides and discharge warm air out the back. Do not place them where the heat and noise will be objectionable.
A 6 inch MINIMUM clearance on the back, and both sides is required for the basic operation and service of the air cooled model.
Airflow is in the sides and out the back

Note: A six inch side clearance with zero top clearance will NOT provide enough air exchange space for optimum performance. 12 inches side clearance is required when there is no top clearance.
Unpacking and Assembly:
Begin with unpacking the ice storage bin. Remove the carton, and using part of the carton as a cushion, tip the bin on its back to remove the skid and attach the legs or casters.
Note: Stacked applications may not use casters.
Return the bin to an upright position. Check the bin top gasket for gaps and tears, fill any in with food grade sealant prior to placing the ice machine on the bin.
Level the top edge of the bin front to back and left to right.
If the ice machine has not been unpacked, do so now. Remove the carton from the skid. After removal of the shipping straps, lift the ice machine off the skid directly onto the bin.

Air cooled models come equipped with a baffle that can be used when the machine is installed in a corner.
The purpose of the baffle is to limit air recirculation. This can occur in a corner when the hot air from the back of the machine is re-drawn back into the machine from the nearest side of the machine.
Install the air baffle as shown. Place the baffle:
On the left rear corner when the left wall and back wall are between 6 and 18 inches from the unit.
On the right rear corner when the right wall and back are between 6 and 18 inches from the unit.
Note: The machine is heavy! Use a mechanical hoist if necessary.
Secure the ice machine to the bin with the hardware provided (two metal straps and 4 bolts).

Cabinet Panel Removal:
Note: The top panel holds the upper edges of the side panels in place.
1. Remove the front panel by removing the two screws connecting the top edge of the front panel to the machine, then pull out at the bottom.
2. Lift up at the front edge and push the top panel back until it releases from the tabs connecting it to the back panel.
3. Remove the screws at the front edge of the left side panel, and pull forward until it releases from the tabs connecting it to the back panel.

Stacking: Requires Kit
Only like models may be stacked. Begin after the bottom unit has been placed on the ice storage bin and secured. Stacking requires heavy duty leg kits. Casters are NOT recommended.
Bottom Machine:
1. Remove front, side, and top panels.
2. Hang the plastic shield from the tabs on the stainless steel bracket.
3. Locate the two notches on the sides of the top edge of the freezing compartment.
Notch
Upper Machine:
8. Knock out 1 hole in the lower left (viewed from the front) corner of the upper unit’s back panel.
Lower Unit:
9. Knock out 1 hole in the upper left (viewed from the front) corner of the lower unit’s back panel.
10. Position the strain reliefs over the wrapped portion of the stacking kit wire harness.
11. Route the Stacking Kit wire harness from the back to the top and bottom machines thru the holes made in steps 8 and 9.
The harness is marked which end goes to which machine.
Push the strain reliefs into place from the back of the machines.
Follow local codes for 24 volt wire
12.Route wire harness in lower ice machine to the controller. Connect to terminal #7. Plug the two free wires onto thermostat terminals #1 and #2
4. Place the bracket over the notches of the freezing compartment.
