FOR THE INSTALLER: Environmental Limitations

MCM1062R

Installation Limitations

The ice making portion of this ice system is designed to be installed indoors, in a controlled environment.

Minimum Maximum

Air Temp 50 Water Temp 40 Water Pressure 20 PSI 80 PSI Voltage 197 253 Operating the ice machine outside of the above

limitations, or outdoors, is potentially damaging to the machine; also it is misuse of the machine, which may void the warranty.

Scotsman Ice Systems are designed and manufactured with the highest regard for safety and performance. They meet 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.

F. 1000F.

Water Limitations

An ice machine is a food manufacturing plant; it takes 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. These general recommendations should help keep the ice maker clean:

1. Filter the water used to produce ice. 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 than 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

Some space on the sides, the back and the top should be allowed for service and utility connections.

Scotsman reserves the right to make design changes and/or improvements at any time.

Specifications and design are subject to change without notice.

FOR THE INSTALLER: Machine & Bin Assembly

Overview:

This ice system is comprised of 4 major assemblies:

1. The ice storage bin.

2. The ice maker itself.

3. The interconnecting refrigerant lines.

4. The remote condenser. Additionally, there will be interconnecting wires

between the ice maker and the condenser. The Scotsman remote condenser is powered from the ice maker. The condenser must be located above the ice maker, usually on the roof.

Storage Bin:

1. Measure the location of the ice machine floor drain relative to the installed location of the bin. Route all drain lines so that when the machine is installed in its normal position, the drain tubes terminate just above the floor drain.

2. Using corner posts from the bin’s carton as a cushion, lay the bin on its back.

3. Install the casters into the leg sockets.

4. Move bin back to an upright position.

5. Check that the back set of casters are in in line to allow the bin to be rolled back and forth.

Ice Maker:

1. Arrange for proper electric, water and drain. See instructions for the plumber and for the

electrician.

2. Position the ice storage bin in the selected location which should have a minimum room temperature of 50-degrees F. and maximum room temperature of 100 degrees F.

3. Inspect the bin top mounting gasket which should be flat, with no wrinkles, to provide a good water seal when the cuber is installed on top of the bin.

4. Install the modular cuber on top of the bin using care to be sure a good seal is made between the two cabinets, use of a mechanical lift is recommended. Align the holes in the bottom back of the cabinet to mate with the two mounting straps on the top rear of the bin.

5. Use bolts and straps found in the hardware package to secure the ice machine to the ice storage bin. Attach the bin bumpers to the bin with the bolt holding the mounting strap to the bin.

When alignment and leveling are completed, tighten the bolts to secure the mounting straps.

7. Hang the scoop holder and scoop from the front edge of the bin (inside the bin).

8. Install the bin bumpers at the back of the bin.

9. Remove all material that is packed inside the bin.

Water Supply

The recommended water supply line is a 3/8-inch O.D. tubing with a minimum operating pressure of 20 PSIG and a maximum of 80 PSIG.

Connect to cold water supply line with standard plumbing fittings, with shut off valve installed in an accessible place between the water supply and the cuber. ln some cases a plumber will be required.

Drain Connections:

Drain tubing and fittings are supplied with the ice bin. All drains are gravity type and must have a minimum of 1/4-inch fall per foot on horizontal runs. The drains to be installed must conform with the local plumbing code.

Install a vertical open vent on the drain line(s) high point to ensure good draining. The ideal drain receptacle is a trapped and vented floor drain.

FOR THE INSTALLER: Remote Condenser

Scotsman Condenser:

Locate the condenser as near as possible to the interior location of the ice maker.

Location of the condenser is limited by the specific length of pre-charged refrigerant tubing supplied for the application. The pre-charged tubing connects the icemaker to the remote condenser. The condenser must be above the ice maker.

Select the best available location, protecting the condenser from extremes of dirt, dust, and sun.

Meet all applicable building codes. Roof Attachment:

Install and attach the remote condenser unit to the roof of the building, using the methods and practices of construction that conform to the local building codes, including having a roofing contractor secure the condenser to the roof.

/////////////////////////////CAUTION/////////////////////////////// Do not connect pre-charged tubing until all routing

and forming of the tubing is complete. See the coupling instructions for connecting instructions.

////////////////////////////////////////////////////////////////////////////

1. Each set of precharged refrigerant lines consists of a 3/8 inch diameter liquid line, and a 1/2 inch diameter discharge line. Both ends of each line have quick connect couplings, one end has flexible tubing: that end goes to the icemaker.

Note: The openings in the building ceiling or wall, listed in the next step, are the minimum sizes recommended for passing the refrigerant lines through.

2. Have the roofing contractor cut a minimum hole for the refrigerant lines of 1.75". Check local codes, a separate hole may be required for the electrical power to the condenser.

3. Route the refrigerant lines through the roof opening.

Follow straight line routing whenever possible. Any excess tubing MUST be retained within the

building.

4. Spiral any excess length of pre charged tubing inside the building. Use a horizontal spiral (as illustrated) to avoid any traps in the lines.

5. Have the roofing contractor seal the holes in the roof per local codes.

6. The flexible line end must be installed behind the icemaker, it is to be looped down from the ice machine connection area then back up to the wall behind the ice machine. This allows the ice machine to be pulled out for service.

FOR THE INSTALLER: Coupling Instructions

MCM1062R

/////////////////////////////CAUTION///////////////////////////// The couplings on the sets of precharged lines are

self sealing when installed properly. Carefully follow the instructions:

//////////////////////////////////////////////////////////////////////////

1. Remove the protector caps and plugs. Wipe the seats and threaded surfaces with a clean cloth to be certain that no foreign matter remains on them.

2. Lubricate the inside of the couplings, especially the O-Rings with refrigerant oil.

•• The 3/8 inch liquid line (schrader valve end)

goes to the remote condenser fitting marked “liquid line”.

•• The other end of the liquid line goes to the

icemaker fitting marked “liquid line.”

•• The 1/2 inch discharge line (schrader valve

end) goes to the remote condenser fitting marked “discharge line”.

•• The other end of the discharge line goes to the

icemaker fitting marked “discharge line”.

3. Begin tightening the couplings together by hand, then using two wrenches (it is important that ONLY the nut on the precharged lines be turned, the other parts of the couplings must NOT be allowed to turn or the process will tear out the diaphragms and they will be loose in the refrigeration system) tighten the coupling until it bottoms out or a definite increase in resistance is felt.

4. Using a marker or pen, mark a line lengthwise from the coupling union nut to the bulkhead. Then tighten the coupling and additional 1/4 turn. As the nut turns, the line will show when 1/4 turn is made.

5. After all connections are made, and after the king valve has been opened, check the couplings for leaks.
