MDT5N40 - Ice Maker Scotsman - Free user manual and instructions

USER MANUAL MDT5N40 Scotsman

This machine is designed to be placed on a counter or on a model DMS21 machine stand. Check sales information for other applications. INSTALLATION LIMITATIONS: This ice system is designed to be installed indoors, in a controlled environment: Min Max Air Temperature 10

Water Pressure 1 bar 5 bar Voltage -5% +10% (Compared to the nameplate) Operating the machine outside of the limitations is misuse and can void any warranty. Scotsman Ice Systems are designed and manufactured with the highest regard for safety and performance. Scotsman reserves the right to make design changes and/or improvements at any time. Specifications and design are subject to change without notice. LOCATION & ASSEMBLY: After uncrating and inspection, the unit is ready for installation. It is important that the machine be installed in a location where it has enough space around it to be accessible for service, and minimum of 150 mm be allowed at the sides for air circulation on air cooled models. A minimum of 150 mm should be allowed at the top for service access. Try to avoid hot, dirty and crowded locations. Machine Stand Installations: Tip the machine stand 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 stand. Turn the leg levelers all the way in preparation for leveling later. Return the stand to the upright position. Counter Top Installations: Locate the plumbing and electrical supply access holes prior to placing the unit on the counter top. 2Ice Maker Dispenser: 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 stand or counter top. If placing on a machine stand, align it with the back. Secure it to the stand with the hardware provided with the stand. If placing on a counter top, no additional fastening is required. Sealing the edges of the dispenser to the cabinet is recommened to make cleaning easier. PLUMBING:

PLUMBING CONNECTIONS MUST

CONFORM TO ALL APPLICABLE CODES

Water Inlet Air Cooled Models: The recommended water supply is potable 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 Models: A separate 3/8" O.D. copper line is recommended, with a separate hand valve to control it. It is connected to a 3/8" FPT condenser inlet at the back of the cabinet. Drains Air Cooled Models: There is one 3/4" FPT drain at the back of the cabinet, the drain line is of the gravity type, and a 3 cm per meter fall is an acceptable pitch for the drain tubing. There should be a vent at the highest point of the drain line, and the ideal drain receptacle would be a trapped and vented floor drain. Use only 3/4" rigid tubing. Water Cooled Models: In addition to the above mentioned drain, a separate condenser drain must be installed. Connect it to the 1/2" condenser drain connection at the back of the cabinet. ELECTRICAL:

ELECTRICAL CONNECTIONS MUST

CONFORM TO ALL APPLICABLE CODES

The electrical power to the unit is supplied through the junction box at the rear of the machine. Check the nameplate (located on the back panel) 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 its own electrical circuit so it would be individually fused. Voltage variation must remain within design limitations, even under starting conditions. The electrical disconnect switch with fuse protection must be a two pole type with a minimum of 3 mm between open contacts.

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? Has the voltage been checked, and compared to nameplate requirements?

3. Have all the plumbing connections been made and

4. Has the machine and bin been leveled?

5. Is there a minimum of 150 mm clearance at the sides of

the machine for proper service access and air circulation?

6. Is the water pressure a minimum of 1 bar?

7. Has the machine been secured to the machine stand (if a

8. Is there clearance over the top of the machine for service

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

Pre-Start Inspection

1. Remove the two front panels.

2. Inspect the interior of the machine for loose screws or

wires. Check that no refrigerant lines are rubbing each other. Check that the fan blade turns freely (air cooled).

3. Remove any and all packaging material including any that

may be inside the ice storage bin.

4. Check that the inner bin bottom is properly seated at the

bottom of the ice storage bin.

5. Check that the unit is installed correctly according to the

final check list. Start Up

31. Open the hand valve, observe that water enters the water

reservoir, fills the tube from the reservoir to the evaporator, and then shuts off.

2. Switch the master switch on.

A. There should be a short (15 second) delay before the gearmotor starts. B. After the gearmotor starts, the compressor will start.

4. On air cooled models, the condenser will begin to

discharge warm air, on water cooled models warm water will be flow into the drain.

5. The unit should soon be making ice.

6. There Are No Adjustments to Make, so replace the

7. Check ice dispensing by holding a container in front of

the Tough Free ice sensor (just below the ice delivery spout). Ice should flow from the spout when a container is present, and stop dispensing when the container is removed.

8. Give the owner/user the manual, instruct him/her in the

operation of the unit, and make sure they know who to call for service.

SANITIZING AND CLEANING

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. Ice Making System: In place cleaning

WARNING: Before proceeding with any cleaning and

maintenance operation, make sure that the electrical power has been disconnected. Monthly: Wipe clean the ice storage bin liner, using a mild detergent solution diluted in lukewarm water. Rinse it and then thoroughly disinfect its surfaces by wiping them with a liquid algaecide. Clean the outside of the cabinet with a mild detergent solution. Cleaning of water system. This is critical to the proper operation of the ice machine. Call the authorized Service Agent at least twice per year. EXTERIOR CLEANING

1. The ice chute may be pulled down to remove it from the

ice dispenser. Wash and sanitize it.

2. The sink grill may be removed for washing and sanitzing.

3. The sink should be flushed with hot water and wiped

clean with sanitizer.

4. The splash panel requires special attention to clean it.

A. Push and release the Splash Panel Cleaning Switch, located between the ice and water spouts. B. Wash the splash panel and wipe with sanitizer. C. Re-push the clean switch or wait 3 minutes for the Touch Free System to reset. MECHANICAL MAINTENANCE This is critical to the proper operation of the ice machine. Call the authorized Service Agent at least twice per year. FAILURE ANALYSIS (What to do before calling for service) If the machine does not work: Is the power on? Is the water supply on? Are the water filters plugged up? If the machine does not make enough ice. Are the air or water temperatures too high? Is the air filter in the machine dirty? If the machine makes and unusual noise. Has the machine received its twice per year maintenance? 4MANUEL D’UTILISATION POUR DISTRIBUTEUR AUTOMATIQUE DE
