Scotsman assumes no liability or responsibility of any kind for products manufactured by Scotsman hat have been altered in any way, including the use of any part and/or other components not specifically approved by Scotsman.
Scotsman reserves the right to make design changes and/or improvements at any time. Specifications and design are subject to change without notice.
UNPACKING AND INSPECTION
1.Call your authorized SCOTSMAN Distributor or Dealer for proper installation.
2.Remove the front panel of the unit and inspect for any concealed damage. Notify carrier of your claim for the concealed damage.
3.Check that refrigerant lines do not rub against or touch other lines or surfaces, and that the fan blade moves freely.
4.Check that the compressor fits snugly onto all its mounting pads.
5.Remove all internal support packing and masking tape.

General Information And Installation
This model is supplied from the factory completely pre-wired and require only electrical power connections to the wire cord provided at rear of the unit.
Make sure that the ice machine is connected to its own circuit and individually fused (see data plate for maximum fuse size). This is a cord-connected unit designed for 115 volt AC power, with a maximum fuse size of 15 amps.
Low voltage can cause improper operation and may be responsible for serious damage to the overload switch and motor windings that is not covered by warranty.
NOTE. All external wiring should conform to national, state and local standards and regulations.
Check voltage on the line and the ice maker’s data plate before connecting the unit. Extension cords must not be used.
Location: If the unit is built into a cabinet with no side ventilation, the ice production will be reduced by 20% of rated capacity, restricted space of an inch or so on each side will cause a 10% reduction. Six inches of space to the left and right will allow the unit to operate satisfactorily.
The daily ice-making capacity is directly related to the condenser air inlet temperature, water temperature, conditions of the condenser air filter and age of the machine.
To keep your SCOTSMAN CUBER at peak performance levels, periodic maintenance checks must be carried out as indicated on Maintenance and Cleaning section of this manual.
Warranty
The warranty statement for this product is provided separately from this manual. Refer to it for applicable coverage. In general warranty covers defects in material or workmanship. It does not cover maintenance, corrections to installations, or situations when the machine is operated in circumstances that exceed the limitations printed in this manual.

Water Supply And Drain Connections
General
When choosing the water supply for the ice cuber consideration should be given to:
a)Length of run
b)Water clarity and purity
c)Adequate water supply pressure
Low water pressure, below 20 psi may cause a malfunction.
Water containing excessive minerals will tend to produce cloudy colored ice cubes, plus scale build-up on parts of the water system.
Water Supply
The recommended water supply line is a 3/8" o.d. copper tube, the water pressure must have a minimum incoming pressure of 20 psig.
Connect the tubing to the 3/4" GAS / BSPP thread water inlet fitting at the back of the ice maker. An adapter is available, the part numbers are: F733219-03 and F640134-00.
Water Drain
The recommended drain tube is a plastic or flexible tube with 18 mm (3/4") I.D. which runs to an open trapped and vented drain.
Note: Although soft, easily kinked vinyl tubing is not recommended for a drain, a short length of ¾” ID vinyl tubing is required to connect a rigid drain tube to the 20 mm (25/32”) fitting on the back of the machine.
NOTE. The water supply and the water drain must be installed to conform to the local code. In some case a licensed plumber and/or a plumbing permit is required.

Final Check List
1.Is the unit in a room where ambient temperatures are above a minimum of 10oC (50oF) even in winter months?
2.Is there at least a 15 cm (6") clearance around the unit for proper air circulation?
3.Is the unit level? (IMPORTANT)
4.Have all the electrical and plumbing connections been made, and is the water supply shut-off valve open?
5.Has the voltage been tested and checked against the data plate rating?
6.Has the water supply pressure been checked to ensure a water pressure of at least 20 psi.
7.Check all refrigerant lines and conduit lines to guard against vibrations and possible failure.
8.Have the bolts holding the compressor down been checked to ensure that the compressor is snugly fitted onto the mounting pads?
9.Have the bin liner and cabinet been wiped clean?
10.Has the owner/user been given the User Manual and been instructed on the importance of periodic maintenance checks?
11.Has the Manufacturer’s registration card been filled in properly? Check for correct model and serial number against the serial plate and mail the registration card to the factory.
12.Has the owner been given the name and the phone number of the authorized SCOTSMAN Service Agency serving him?
Connect Power, Water and Drain. Level the cabinet.

Operating Instructions
Start Up
After having correctly installed the ice maker and completed the plumbing and electrical connections, perform the following “Start-up” procedure.
A.Remove the condenser air filter then remove the front panel, Locate the cleaning switch on the control box.
B.Switch the cleaning switch to the cleaning position. This will close the electrical circuit to the water inlet valve and to the hot gas valve
C.Switch the power ON and push the green button switch. Unit will start up in charging cycle mode. During this cycle the components energized are:
Water Inlet Solenoid Valve
Hot Gas Solenoid Valve
Water Pump
Fan Motor
D.Operate the unit in the water charging cycle for about three/four minutes till water flows out from the drain hose, then move the cleaning switch to the operation position.
NOTE. During the charging cycle, the water inlet solenoid valve is energized. The water flows through the valve to the back side of the evaporator platen and then down to fill up the ice machine sump for the next freezing cycle.
