Manual abstract: user guide SCOTSMAN MDT4F12
Detailed instructions for use are in the User's Guide. MDT3F and MDT4F Manual
Purpose of this manual: To provide detailed installation and operation instructions; to give insights into how the machine works; to list possible causes for problems; and to suggest procedures for specific types of service.
MDT3F & MDT4F
The MDT3F and MDT4F are combination ice makers and dispensers. The refrigeration system is air cooled, using R-134a as a refrigerant. The control system uses electric eyes as a bin control and a water level sensor as the water safety control. As ice is made, it fills a plastic storage bin. When ice is needed, a motor rotates a stainless steel vane inside the storage bin and sweeps the ice into the spout.

To The Installer:
A professional installation of any product is critical to the long term satisfaction of the user. The ice maker-dispenser is designed to be installed either on a counter, or, using a wall hanging kit, hung from a wall. Determine the location from the anticipated use and any options planned for. This machine is air cooled and blows air out the lower left side of the cabinet. Do not install the machine where the side to side air flow might be blocked.

MDT3F & MDT4F
Water Quality: The quality of the water supplied to the machine will directly affect the purity of the ice and the reliability of the machine. While the condition of the water supplied to a building is normally out of the control of the user, water can be treated at the point of use. There are two major types of water impurities: suspended solids (those that are carried along with the water and may be filtered out) and dissolved solids (those that are part of the water and have to be treated). A water filter is always a good idea, but does require regular maintenance to change the cartridge. In some water conditions, water treatment may be required. Generally this means a polyphosphate feeder of some kind. Water softeners are not recommended. General Installation: Place the machine in its final location. Remove the top, right and left side panels: 1. Remove two screws at the back of the top panel. 2. Pull up on the back of the top panel and remove it. 3. Remove screws from the sides (top and bottom) of the side panels and from the splash panel. 4. Pull the side panels back and off the machine. Plumbing connections may be made thru holes in the back of the cabinet or thru the base. ·Route the sink drain to the back of the cabinet. Route the bin drain to the back panel.

Install the back panel of the stainless steel panel kit now (if used). After all plumbing and internal wiring has been done, replace the side and back panels. Level the unit front to back and left to right. The machine does not require sealing to the counter due to the gasket on the base.

For The Electrician
Electrical connections: Check the nameplate for voltage and current requirements. An electrical cord is not supplied. Connect the MDT3F or MDT4F to a separate electrical circuit. Wiring to the machine must conform to all codes. A licensed electrician may be required in some situations. Remove the back panel to make the electrical connection. The electrical connection is made on the terminal strip in the junction box inside the machine. Replace the back panel when the electrical connections are complete.

For The Plumber
Drains: The dispenser requires a gravity drain. The pitch on the drain tubes must be at least ¼ inch fall per foot of horizontal run. On long horizontal runs, a vent at the back of the cabinet will improve draining, and is recommended. There are two drains to connect: A sink drain, a 7 8" plastic tube; and the bin drain, a 5 8" plastic tube. Install rigid tubing between the machine and the building drain. Route the drains separately to the building drain. Water supply: Connect cold, potable water to the machine. A hand valve near the location is recommended. A water filter is also a good idea. Follow all local codes.

Wall Mount Kit (KWB4):
Top Wall Bracket: 1. Hold the bracket on the wall where it will be mounted. 2. Mark on the wall the positions of the holes in the bracket. 3. If needed, drill pilot holes for the fasteners. 4. Secure the bracket to the wall with fasteners of sufficient strength to hold up the MDT4F. Bottom Wall Bracket: 1. Lift up and hang the dispenser from the top wall bracket. 2. Position the bottom wall bracket so that the molding on the dispenser base bottoms in the channel of the wall bracket. 3. Secure the bracket to the wall. Bottom Fitting Cover: 1. Connect electrical power, water inlet, bin drain and sink drain of the dispenser thru the bottom of the case.
Top Panel Enlarge Holes
1. Top Case Hanger Bracket: Attaches to the frame of the dispenser. 2. Top Wall Bracket: Mounts to the wall and engages the top case hanger bracket to support the dispenser. 3. Bottom Wall Bracket: Mounts to the wall and spaces the base of the dispenser away from the wall. 4. Bottom Fittings Cover: Fastened to the bottom wall bracket to hide the utility connections.
Top Case Bracket
Installation: Check building wall for the strength required to support a machine of this weight and size. Note that if at least 6" of space is not left above the machine, cleaning and most service of the machine will require removal of the machine from the wall mounts. All utilities are to be routed thru the base. The back panel is not used when the machine is hung from the wall. Top Case Hanger Bracket 1. Remove top panel. 2. Remove back cover and save the 4 screws for mounting the bracket. 3. Drill out the holes (as marked in the illustration) in the back of the frame with a 3/16" drill bit. 4. Place top hanger bracket on the inside of the frame and fasten to the frame with the four screws removed in step 2.
Bottom Cover Wall Brackets
Secure With Screws
2. Secure bottom fitting cover to the bottom wall bracket with the four sheet metal screws provided in this kit.
