Initial Start UP

NME454, 654 & FME504, 804

Pre-Start Inspection

1.Remove the front and side service panels.

2.Check that any shipping blocks have been removed.

3.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).

4.Check that the unit is installed correctly according to the final check list (page 8).

Start Up

1.Go through the prestart inspection.

2.Open the hand valve, observe that water enters the water reservoir, fills the tube from the reservoir to the evaporator, and then shuts off. Check for leaks.

3.Switch the master switch on. There will be a short delay before the gearmotor and compressor will start.

4.On air cooled models, the condenser will begin to discharge warm air, on water cooled models, the water regulating valve will open, and warm water will be discharged into the drain.

5.The unit should soon be making ice, if desired, the low side pressure can be checked: it should be

34PSIG + or - 4 PSIG.

The suction line temperature at the compressor is normally very cold, nearly to the point of frost up to the compressor body, but not on it.

The air cooled discharge pressure will depend upon air and water temperatures, but should be between 220 PSIG and 300 PSIG.

The water cooled discharge pressure should be

constant at about 245 PSIG.

The above numbers are for new, clean machines, you can expect to see some values higher, and some lower between different units.

6.THERE ARE NO ADJUSTMENTS TO MAKE, so replace the panels.

7.Clean and/or sanitize the storage bin interior, wipe off the exterior with a clean, damp cloth.

8.Give the owner/user the service manual, instruct him/her in the operation of the unit, and make sure they know who to call for service.

9.Fill out the manufacturer’s registration and mail it to Scotsman.

Water Level: The correct water level should be

checked when the machine is making ice. Check the water level in the reservoir and compare it to the horizontal line molded into the side of the reservoir.

The correct level should be between 18" above and 14" below the line. If needed, bend the float arm up or down to adjust the water level.

FME504, FME804, NME654, Flake and Nugget Ice Machine, NME454 specifications

Scotsman Ice Systems is known for its high-quality ice machines, and models such as the NME454, NME654, FME804, and FME504 are no exceptions. Designed with both performance and efficiency in mind, these machines cater to various business needs, from restaurants to convenience stores.

The NME454 and NME654 units are renowned for their compact design, making them ideal for establishments with limited space. Despite their smaller size, these machines do not compromise on ice production capacity. The NME454 can produce up to 430 pounds of ice per day, while the NME654 boasts an impressive output of up to 600 pounds. Both models utilize Scotsman's signature innovative technology to ensure consistent ice quality, primarily in the form of nugget ice, which is favored for its ability to cool beverages quickly.

In contrast, the FME804 and FME504 are larger-capacity machines that cater to high-volume requirements. The FME804 can produce around 800 pounds of ice daily, making it suitable for busy restaurants or bars. The FME504, while slightly smaller, still offers impressive production capabilities of up to 500 pounds per day. These machines incorporate advanced features such as the AquaArmor protective layer, which inhibits bacterial growth, ensuring that the ice produced is not only abundant but also hygienic.

All four models utilize an innovative air-cooled design that enhances energy efficiency and reduces operational costs. The easy-to-use control panel allows for straightforward operation, and maintenance is streamlined thanks to easily accessible components. Additionally, the quiet operation of the machines ensures that they can be used in front-of-house areas without distracting customers.

In terms of construction, Scotsman ice machines are built to last with corrosion-resistant materials, ensuring longevity in demanding environments. With simple installation processes and compatibility with various environments, including indoor and outdoor settings, these units provide adaptability for any business scenario.

Overall, Scotsman’s NME454, NME654, FME804, and FME504 ice machines combine robust performance with innovative technology, catering efficiently to diverse ice production needs while maintaining high standards of hygiene and reliability.
