May, 1991 Page 1 MF400 FOR THE INSTALLER The MF400 is designed to fit the following Scotsman storage bins. BH550 with bin top KBT20 HTB500 with bin top KBT20 The normal finish for the machine is enamel sandalwood. [. . . ] This high pressure liquid then goes through the liquid line to the capillary tube. The capillary tube meters liquid refrigerant into the evaporator, the volume of liquid refrigerant depending upon the temperature of the evaporator; warmer evaporators get more refrigerant and colder evaporators get less. At the evaporator, the refrigerant enters an area of relatively low pressure, where it can easily "boil off" or evaporate. As it evaporates, it absorbs heat from the evaporator and whatever is in contact with it (such as the water inside it). After the evaporator, the refrigerant, now a low pressure vapor, goes through the suction line back to compressor, where the cycle is repeated.

In order to receive the best return for that investment, it MUST receive periodic maintenance. It is the USER'S RESPONSIBILITY to see that the unit is properly maintained. It is always preferable, and less costly in the long run, to avoid possible down time by keeping it clean; adjusting it as needed; and by replacing worn parts before they can cause failure. The following is a list of recommended maintenance that will help keep the machine running with a minimum of problems. Maintenance and Cleaning should be scheduled at a minimum of twice per year. /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// 10.

Prepare the cleaning solution: Mix eight ounces of Scotsman Ice Machine Cleaner with three quarts of hot water. Slowly pour the cleaning solution into the water reservoir until it is full. As the ice maker begins to use water from the reservoir, continue to add more cleaning solution to maintain a full reservoir. reservoir. Continue ice making for at least 15 minutes, to flush out any cleaning solution. //////////////////////////////WARNING////////////////////////// DO NOT USE any ice produced from the cleaning solution. [. . . ] Remove the cover from the top of the centrifugal switch assembly and remove the electric wires from the microswitch. To replace just the centrifugal switch, remove two machine screws retaining the switch, and remove the switch. If the motor is to be removed, the next step is to remove the four screws holding down the plastic switch assembly housing and lift the housing off of the motor top. Remove the centrifugal switch mechanism from the rotor by unscrewing the machine screw at the top of the rotor. [. . . ]
