Installation Limitations:

This ice system is designed to be installed indoors, in a controlled environment:

Min Max

Air Temperature 50 Water Temperature 40 Water Pressure 20 psi 80 psi Voltage -10% +10% (Compared to the Nameplate) Operating the machine outside of the limitations is

misuse and can void the warranty. Scotsman Ice Systems are designed and

manufactured with the highest regard for safety and performance. They meed or exceed the standards of UL, NSF, and CSA.

Scotsman assumes no liability or responsibility of any kind for products manufactured by Scotsman that 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 changes are subject to change without notice.

Water Limitations:

An ice machine is a food manufacturing plant; it takes in a raw material, water, and turns it into a food product, ice. The purity of the water is very important in obtaining pure ice and in maximizing product life. This section is not intended as a complete resource for water questions, but it does offer these general recommendations:

1. Filter the water used to make ice. That is the water going to the “potable” water connection. Water filters vary greatly in ability and function. Install one that filters out suspended solids to a dimension of 5 microns or smaller. The finer the filter the better, but finer filters will clog sooner that course ones. It may be necessary to add a course filter ahead of the fine filter to prolong filter life.

2. Check with a water treatment specialist for a water test, and recommendations regarding filters and treatment.

Service Limitations:

There must be space above, to at least one side, to the back, and of course the front for service access.

ICE CHUTE INSTALLATION

MFE400

FOR THE INSTALLER

Location

After uncrating and inspection, the unit is ready to be installed.

It is important that the machine be installed in a location where it has enough space around it for service, and a minimum of 6" be allowed all sides for air circulation. The machine, when air cooled, draws air in the front, and exhausts it out the sides and back.

Try to avoid hot, dirty and crowded locations. Be sure that the location for the machine is within the limitations described on page 3.

Storage Bin

Tip the uncrated storage bin on its back, using parts of the carton to protect the exterior finish. Install the legs into the threaded holes in the bottom of the bin. Turn the leg levelers all the way in preparation for leveling later.

Return the bin to the upright position, remove paper covering the bin gasket.

Install bin top if required.

5. Remove the rubber cap from the top of the ice chute. Leave one hose clamp on the chute.

6. Push the ice chute against the stainless spout (the end of the spout will go into the chute).

7. Slide the rubber cap over the top of the stainless spout. Push down until it fits tightly around the spout.

8. Secure the rubber cap to the spout with the two hose clamps, in the molded grooves; one above and one below. Keep hose clamp screws away from evaporator.

9. Attach the insulation halves around the top of the evaporator. Secure with the ty-wrap provided. Finish installation per service manual.

Note: Do not push bin into position: but lift it there. Pushing a bin, especially one with ice in it, can cause damage to the legs and the leg mounts.

Ice Maker

The machine is heavy, so the use of a mechanical lift is recommended for lifting the machine high enough to install on top of the bin. After the machine is placed on the bin, line it up so that the ice discharge opening in the base of the machine is over the open hole in the bin top.

Ice Chute Installation

After the MFE400 has been installed on the ice storage bin, the ice chute needs to be installed:

1. With the top panel off, remove all packing material (bubble pack) from above the ice chute and chute cap. Cut the ty-wrap holding the chute assembly in place.

2. Remove the insulation halves and ty-wrap packed inside the cabinet, retain for later use.

3. Remove the cardboard support from under the ice chute.

4. Insert the ice chute/bin thermostat assembly into the large hole in the bottom of the ice machine. Check that bin thermostat cap tube is free from contact with most components.

FOR THE PLUMBER

CONFORM TO ALL APPLICABLE CODES

Water Inlet

Air Cooled: The recommended water supply is cold water. Use 3/8" O.D. copper tubing, connect to the 3/8" male flare at the back of the cabinet. Install a hand valve near the machine to control the water supply.

Water Cooled: A separate should be connected to the condenser inlet, with a separate hand valve to control it.

Drains

Air cooled: There is one hose to connect to for a drain. This drain is a gravity drain, and a minimum of

⁄4" per foot fall is needed

for horizontal portions of the drain line.

The ideal drain receptacle is a trapped and vented floor drain.

Use only rigid tubing. Water Cooled Models: In addition to

the above mentioned drain, separate condenser drain must be installed. Connect to the

⁄8" condenser drain

tube. Storage Bin: A separate gravity type

drain needs to be run. This drain line should be insulated.

FOR THE ELECTRICIAN

CONFORM TO ALL APPLICABLE CODES

The electrical power to the unit is to be wired through the cabinet to the control box. In the control box, connect to the terminal strip provided.

1. Remove the front, top and right side panels.

2. Remove the control box cover.

3. Route the power cord thru the cabinet to the control box.

4. Connect wires to the terminal strip.

5. Replace all panels. Check the nameplate (located on the back of the

cabinet) for the voltage requirements, and for the minimum circuit ampacity. The machine requires

a solid chassis to earth ground wire.

The ice maker should be connected to it’s own electrical circuit so that it is individually fused. Voltage variation must remain within design limitations, even under starting conditions.

All external wiring must conform to national, state, and local electrical codes. The use of e licensed electrician is required to perform the electrical installation.

FOR THE INSTALLER: Final Check List

1. Is the ice system installed indoors in a location where the air and water temperatures are controlled, and where they do not exceed the design limitations?

2. Is there an electrical service disconnect within sight of the installed machine?

3. Have all the plumbing connections been made and checked for leaks?

4. Has the machine and bin been leveled?

5. Is there a minimum of 6" clearance around the machine for proper service and air circulation?

6. Is the water pressure a minimum of 20 psig?

7. Has the ice discharge tube been installed?

8. Is there a water shut off installed near the machine?

9. Have all shipping materials been removed?
