Scotsman FDE474 Service Manual

Introduction

FDE474

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.

The FDE474 is an ice maker and dispenser combined into one cabinet. 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:

FDE474

A professional installation of any product is critical to the long term satisfaction of the user. The FDE474 is designed to be installed either on a counter, or, using a wall hanging kit, hung from a wall. Another option is a kit to increase the cabinet height which will allow taller containers to be placed under the spout. 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.

Cooling Air Flow

Warm Air

Exhaust

The machine will require electrical power, water and a drain. Follow all local codes. Rough in the utilities before placing the machine into position (see For The Electrician and For The Plumber).

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 for the FDE474.

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.

Route the electrical power cord from the junction box inside the cabinet. thru the back panel .

Route the inlet water line thru the back panel or base to the flare fitting inside the cabinet.

Install the stainless steel panel kit (if used) now. 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 FDE474 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 1/4 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 plastic tube; and the bin drain, a

” 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.

Top Panel

Installation: Check building wall for the strength

required to support a machine of the FDE474’s 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.

Final Check List & Initial Start Up

1. Is the machine located indoors where the temperature limitations are not exceeded?

2. Is there at least 6" clearance on both sides of the cabinet for adequate air flow?

3. Is the water supply adequate, and has a shut off valve been installed?

4. Is the cabinet level?

5. Have all of the electrical and drain connections been made?

Initial Start Up

1. Remove 2 screws at the back of the top panel and remove the top panel.

2. Remove screws and the side panels.

3. Open the water supply shut off valve.

4. Watch the water fill the reservoir. Check that it flows in and fills the reservoir near to the mark molded into the side of the reservoir. Check that the float shuts off the water flow when the tank is full. Check for leaks. Tighten hose clamps as needed.

5. Plug the unit in or switch on the electrical power. After a few seconds the machine will start.

6. Let the machine operate, listen for any unusual noises. If needed, reposition tubing & panels to eliminate vibration.

After the unit has been operating for about 10 minutes, there should be enough ice in the bin to test the dispense system.

7. Using a container, push the glass filler lever in and see that ice is dispensed (the bin drive motor continues to run as long as the glass filler lever is pushed in).

8. Move the water switch (rocker switch on the front panel) to ON. Then use a container to push in the glass filler lever. Both water and ice should be dispensed.

9. Pour water into the sink and check that the drain does not leak but drains the water rapidly.

10. Explain to the user the maintenance requirements and operation of the machine.

11. Fill out the Warranty Registration and Customer Evaluation form. Mail it to Scotsman.

12. Leave the service manual with the owner/user and explain who should be called if service is needed.

User Operation

The FDE474 is an automatic ice vending machine. All it requires is cool air, clean water and an adequate supply of electrical power.

To Vend Ice:

Push the glass filler lever in and hold it in until the container is full of ice. Do NOT overfill the container or a build up of ice in the sink or a back up of ice in the spout will occur.

To Vend Ice and Water.

Switch the Water Switch to ON. Push in the glass filler lever; water and ice will be dispensed into the container below the spout. Note: The water is NOT cooled, it is the same temperature as the building supply water.

Daily Maintenance: Pour hot water into the sink to flush out any debris or build up. Wipe the cabinet off, wash the sink and grill to keep minerals from accumulating.
