Water Quality (Ice Making Circuit)

Potable

The quality of the water supplied to the ice machine will impact the time between cleanings and the product's lifespan. Water can contain impurities either in suspension or in solution. Suspended solids can be filtered out. Dissolved solids cannot be filtered; they must be diluted or treated. Water filters are recommended to remove suspended solids, and some filters can also treat dissolved solids. Check with a water treatment service for a recommendation.

RO Water

This machine can be supplied with Reverse Osmosis water, but the water conductivity must be no less than 10 microSiemens/cm.

Potential for Airborne Contamination

Installing an ice machine near a source of yeast or similar material can result in the need for more frequent sanitation cleanings. Using a filter that does not remove chlorine, such as the Scotsman Aqua Patrol, will improve this situation as most water filters remove chlorine from the water supply to the machine, which contributes to contamination.

Warranty Information

The warranty statement for this product is provided separately. In general, the warranty covers defects in material or workmanship. It does not cover maintenance, corrections to installations, or situations when the machine is operated in circumstances exceeding the printed limitations.

Location

While the machine will operate satisfactorily within the listed air and water temperature limits, it will produce more ice when those temperatures are nearer the lower limits. Avoid locations that are hot, dusty, greasy, or confined. Air-cooled models need plenty of room to breathe and must have at least six inches of space at the back for air discharge; however, more space will allow better performance.

Airflow

Air flows into the front of the cabinet and out the back. The air filters are on the outside of the front panel and are easily removed for cleaning.

Options

Side air flow kits KPFSA223 or KPFSA227 are available for air-cooled models. A filter kit for the remote condenser is KERCF. Ice is made until it fills the bin enough to block an infrared light beam inside the base of the machine. A field-installed kit (KVS) is available to adjust the maintained ice level lower.

Diagnostic Capabilities

The standard controller has excellent diagnostic capabilities and communicates to the user through the AutoAlert light panel, seen through the front panel. Field-installed kits (KSBU and KSB-NU) are available to log data and provide additional information.

Bin Compatibility

All models have the same footprint: 22 inches wide by 24 inches deep. Confirm available space when replacing a prior model.

Bin & Adapter List

B322S: No adapter needed
B330P or B530P or B530S: Use KBT27
B842S: Use KBT39

Backflow

The design of the float valve and reservoir prevents potable water backflow by means of a 1" air gap between the reservoir's maximum water level and the float valve water inlet orifice.

Drain

There is one ¾” FPT condensate drain fitting at the back of the cabinet. Water cooled models also have a ½” FPT discharge drain connection on the back panel.

Attach Tubing

Connect the potable water supply to the potable water fitting, 3/8” OD copper tubing or the equivalent is recommended.
Water filtration is recommended. If there is an existing filter, change the cartridge.
Connect the water-cooled water supply to the condenser inlet.
- Note: Do NOT filter water to the water-cooled condenser circuit.
Drains - use rigid tubing: Connect the drain tube to the condensate drain fitting. Vent the drain.
Connect the water-cooled condenser drain tube to the condenser outlet. Do not vent this drain.
Do not Tee ice machine drains into the drain tube from the ice storage bin or dispenser. Backups could contaminate and/or melt the ice in the bin or dispenser. Be sure to vent the bin drain.

Follow all local and national codes for tubing, traps, and air gaps.

Electrical Connection

The machine does not include a power cord; one must be field supplied or the machine hard wired to the electrical power supply. The junction box for the power cord is on the back panel. Refer to the dataplate on the machine for minimum circuit ampacity and determine the proper wire size for the application. The dataplate also includes the maximum fuse size.

Connect electrical power to wires inside the junction box in the back of the cabinet. Use a strain relief and connect a ground wire to the ground screw. Remote models power the condenser fan motor from marked leads in the junction box. Do not use an extension cord. Follow all local and national codes.

Refrigeration

Remote Condenser Models

The correct remote condenser fan and coil must be connected to the ice making head. Liquid and discharge tubing connections are on the back of the ice machine cabinet. Tubing kits are available in several lengths to accommodate most installations.

Tubing Kit Numbers

BRTE10
BRTE25
BRTE40
BRTE75

Condenser Location Limits

The condenser location must not exceed any of the following limits:

Maximum rise from the ice machine to the condenser: 35 physical feet
Maximum drop from the ice machine to the condenser: 15 physical feet
Physical line set maximum length: 100 feet
Calculated line set length maximum: 150 feet

Calculation Formula

Drop = dd x 6.6 (dd = distance in feet)
Rise = rd x 1.7 (rd = distance in feet)
Horizontal Run = hd x 1 (hd = distance in feet)
Calculation: Drop(s) + Rise(s) + Horizontal Run = dd + rd + hd = Calculated Line Length

Calculation Examples

The condenser is to be located 5 feet below the ice machine and then 20 feet away horizontally. 5 feet x 6.6 = 33. 33 + 20 = 53. This location is acceptable.
The condenser is to be located 35 feet above and then 100 feet away horizontally. 35 x 1.7 = 59.5. 59.5 + 100 = 159.5. 159.5 exceeds the 150 maximum and is NOT acceptable.

Operating a machine with an unacceptable configuration is misuse and will void the warranty.

Installation Notes

Do not reuse condenser coils contaminated with mineral oil.
A headmaster is required for all remote condenser systems.
Use of non-Scotsman condensers requires pre-approval from Scotsman Engineering.

Setup Guide

To operate the Scotsman N1322, follow these steps:

Plug in the machine and turn it on
Set the desired ice production using the touch display
Wait for the machine to produce the desired amount of ice
Empty the ice bin as needed.

Remote Condenser Location Limits

Use the following for planning the placement of the condenser relative to the ice machine:

Location Limits

Condenser location must not exceed ANY of the following limits:

Maximum rise from the ice machine to the condenser is 35 physical feet.
Maximum drop from the ice machine to the condenser is 15 physical feet.
Physical line set maximum length is 100 feet.
Calculated line set length maximum is 150.

Calculation Formula

Drop = dd x 6.6 (dd = distance in feet)
Rise = rd x 1.7 (rd = distance in feet)
Horizontal Run = hd x 1 (hd = distance in feet)
Calculation: Drop(s) + Rise(s) + Horizontal Run = dd + rd + hd = Calculated Line Length

Configurations that do NOT meet these requirements must receive prior written authorization from Scotsman to maintain warranty.

Do NOT

Route a line set that rises, then falls, then rises.
Route a line set that falls, then rises, then falls.

Calculation Example 1: The condenser is to be located 5 feet below the ice machine and then 20 feet away horizontally. 5 feet x 6.6 = 33. 33 + 20 = 53. This location would be acceptable.

Calculation Example 2: The condenser is to be located 35 feet above and then 100 feet away horizontally. 35 x 1.7 = 59.5. 59.5 + 100 = 159.5. 159.5 is greater than the 150 maximum and is NOT acceptable.

Operating a machine with an unacceptable configuration is misuse and will void the warranty.

For The Installer Remote Condenser

Locate the condenser as near as possible to the interior location of the ice machine. Allow it plenty of space for air and cleaning: keep it a minimum of two feet away from a wall or other rooftop unit.
Note: The location of the condenser relative to the ice machine is LIMITED by the specification on the prior page.

Roof Penetration

A roofing contractor may be required to make and seal the hole in the roof for the line sets.
The suggested hole diameter is 2 inches. Ensure compliance with all applicable building codes.

Roof Attachment

Install and attach the remote condenser to the roof of the building using methods that conform to local building codes. A roofing contractor should secure the condenser to the roof.

Line Set Routing and Brazing

(applies to remote units only)

Do not connect the refrigeration tubing until all routing and forming of the tubing are complete. See the Coupling Instructions for final connections.

Refrigeration Tubing

Each set of tubing lines contains a 3/8” diameter liquid line and a 1/2” diameter discharge line. Both ends of each line are designed for field brazed connections.
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.
Have the roofing contractor cut a minimum hole of 2” for the refrigerant lines. Check local codes, as a separate hole may be required for the electrical power supply to the condenser.
Caution: Do NOT kink the refrigerant tubing while routing it.
Route the refrigerant tubes through the roof opening using straight-line routing whenever possible. Excess tubing must be cut to proper length before connecting to the ice maker and condenser.
The tubing must be evacuated after connection to the ice maker or condenser before opening the ball valve.
Have the roofing contractor seal the holes in the roof per local codes.

Line Set Routing and Brazing

Do not connect the refrigerant tubing until all routing and forming of the tubing is complete. Final connections require brazing; steps must be performed by an EPA certified type II or higher technician. The lineset of tubing contains a 3/8” diameter liquid line and a 1/2” diameter discharge line.

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.

Have the roofing contractor cut a minimum hole for the refrigerant lines of 1 3/4”. Check local codes, a separate hole may be required for the electrical power supply to the condenser.

Caution: Do NOT kink the refrigerant tubing while routing it.

At Condenser

Remove protective plugs from both connections and vent the nitrogen from the condenser.
Remove the tubing access bracket to allow more room for brazing.
Route the lineset tubes to their connection points.
Clean tubing ends and position into stubs.

Ensure the tube and stubs are round, dressing with a swage tool if needed.

At Head

Remove the tubing access bracket to allow more room for brazing.
Confirm connection ball valves are fully closed.
Remove protective plugs from both connections.
Remove caps from access valve connections.
Remove cores from access valves.
Connect refrigeration hoses to access valves.
Connect dry nitrogen source to the liquid line connection.
Shorten tubing to the correct length, clean ends, and insert them into valve stubs.
Note: Be sure tube and stubs are round, dress with swage tool if needed.
Add heat sink material to the ball valve body.
Open nitrogen and flow 1 psi nitrogen into the liquid line tube and braze the liquid line and suction line tubes to the valve stubs.
With nitrogen flowing, braze the liquid and suction line connections.

At Condenser

Braze the liquid and suction line connections.

At Head

Remove the nitrogen source.
Return valve cores to access valves.
Connect a vacuum pump to both access valves and evacuate the tubing and head to at least a 300-micron level.
Remove the vacuum pump and add R-404A to all three tubes to provide positive pressure.
Leak check all braze connections and repair any leaks.
Open both valves to full open.

Note: The full refrigerant charge is contained in the receiver of the ice machine.

Water Remote Models

The water supply for ice making must be cold, potable water. There is a single 3/8” male flare potable water connection on the back panel.

Backflow

The design of the float valve and reservoir prevents potable water backflow by means of a 1" air gap between the reservoir's maximum water level and the float valve water inlet orifice.

Drain

There is one ¾” FPT condensate drain fitting at the back of the cabinet.

Attach Tubing

Connect the potable water supply to the potable water fitting, 3/8” OD copper tubing or the equivalent is recommended.
Change the cartridge on the existing water filter (if any present).
Connect the drain tube to the condensate drain fitting. Use rigid tubing.
Vent the drain tubing between the ice machine and the building drain.

Do not Tee ice machine drains into the drain tube from the ice storage bin or dispenser. Backups could contaminate and/or melt the ice in the bin or dispenser. Be sure to vent the bin drain. Follow all local and national codes for tubing, traps, and air gaps.

Final Check List

After Connections

Wash out the bin. Optionally, sanitize the interior of the bin.
Locate the ice scoop (if supplied) and have it available for use when needed.

Push and release the On button. The machine will start in about two minutes.
Soon after starting, air-cooled models will begin to blow warm air out the back of the cabinet, and water-cooled models will drain warm water from the condenser drain tube. Remote models will discharge warm air from the remote condenser. After about 5 minutes, ice will begin to drop into the bin or dispenser.
Check the machine for unusual rattles. Tighten any loose screws, and ensure no wires are rubbing against moving parts. Check for tubes that rub. For remote models, check brazed connections for leaks and retighten as needed.
Fill out the warranty registration form and either file it online or mail it.
Notify the user of the maintenance requirements and whom to call for service.

Maintenance

The ice machine requires five types of maintenance

Air Filters/Cooled Condenser Coils Cleaning
- Air-cooled and remote models need their air filters or condenser coils cleaned regularly.
Scale Removal
- At least twice a year, but in some water conditions, it might be every 3 months. The yellow De-Scale & Sanitize light will switch on after a set period as a reminder. The default time period is 6 months of power-up time.
Sanitization
- Every time the scale is removed or as often as needed to maintain a sanitary unit.
Sensor Cleaning
- Every time the scale is removed.
Top Bearing Check
- At least twice a year or every time the scale is removed.

Frequency

Air Filters: At least twice a year, but in dusty or greasy air, monthly.
Scale Removal: At least twice a year. In some water conditions, it might be every 3 months.
Sanitizing: Every time the scale is removed or as often as needed to maintain a sanitary unit.
Sensor Cleaning: Every time the scale is removed.
Top Bearing Check: At least twice a year or every time the scale is removed.

Air Filters

Pull air filter(s) from the panel.
Wash the dust and grease off the filter(s).
Return it(them) to their original position(s).

Do not operate the machine without the filter in place except during cleaning.

Air-Cooled Condenser

If the machine has been operated without a filter, the air-cooled condenser fins will need to be cleaned. They are located under the fan blades. The services of a refrigeration technician will be required to clean the condenser.

Remote Air-Cooled Condenser

The condenser fins will occasionally need to be cleaned of leaves, grease, or other dirt. Check the coil every time the ice machine is cleaned.

Exterior Panels

The front and side panels are durable stainless steel. Fingerprints, dust, and grease will require cleaning with a good quality stainless steel cleaner.
Note: If using a sanitizer or a cleaner that contains chlorine on the panels, after use be sure to wash the panels with clean water to remove chlorine residue.

Water Filters

If the machine has been connected to water filters, check the cartridges for the date they were replaced or for the pressure on the gauge. Change cartridges if they’ve been installed for more than 6 months or if the pressure drops too much during ice making.

Scale Removal and Sanitation

Note: Following this procedure will reset the de-scale and sanitize light.

Remove the front panel.
Push and release the Off button.
Remove ice from the bin or dispenser.
Turn the water supply to the float valve OFF.
Drain the water and evaporator by disconnecting the leg of the hose connected to the water sensor and draining it into the bin. Return the hose to its original position.
Remove the water reservoir cover.
Mix a solution of 8 ounces of Scotsman Clear One Scale Remover and 3 quarts of 95-115 degree F. potable water.
Caution: Ice machine scale remover contains acids. Acids can cause burns. If concentrated cleaner comes in contact with the skin, flush with water. If swallowed, do NOT induce vomiting. Give large amounts of water or milk. Call a physician immediately. Keep out of the reach of children.
Pour the scale remover solution into the reservoir. Use a small cup for pouring.
Push and release the Clean button: the auger drive motor and light are on, C is displayed and the De-scale light blinks. After 20 minutes, the compressor will start.
Operate the machine and pour the scale remover into the reservoir until it is all gone. Keep the reservoir full. When all the scale remover solution has been used, turn the water supply back on. After 20 minutes of ice making, the compressor and auger motor will shut off.
Turn the water supply to the ice machine OFF.
Drain the water reservoir and evaporator by disconnecting the leg of the hose connected to the water sensor and draining it into the bin or a bucket. Return the hose to its original position. Discard or melt all ice made during the previous step.
To sanitize the water system, mix a locally approved sanitizing solution. An example of a sanitizing solution is mixing one ounce of liquid household bleach and two gallons of 95 – 115 degree F. water.
Pour the sanitizing solution into the reservoir.
Push and release the On button.
Switch the water supply to the ice machine on.
Operate the machine for 20 minutes.

Return the front panel to its original position and secure it with the original screws.

Check Top Bearing

This task should only be done by a qualified service technician. The bearing in the breaker should be checked at least two times per year.

Remove the bail clamp and ice chute cover.
Unscrew the ice sweep.
Remove the water shed and unscrew the breaker cover (left-hand threads).

Inspect the top of the bearing. When new, the grease is white. Over time, some gray will appear over the rollers, which is normal. Add grease to replace the gray grease or if gaps between rollers are visible. If grease is watery, all gray, or rust is visible, have the bearing replaced.

Bearing Service

This task should only be done by a qualified service technician If the grease is uniformly white, no further action is needed. If very gray, rusty, wet or has any embedded metal, have the bearing replaced

If the bearing only needs grease, or to confirm the quality of the grease low in the bearing, inject grease into the lower part of the bearing using Scotsman grease needle pn 02-3559-01 and Scotsman bearing grease cartridge, pn A36808-001. Be sure to inject grease evenly and thoroughly.

Push Off to confirm the selection.

Sensors

The control that senses bin full and empty is a photoelectric eye and must be kept clean. At least twice a year, remove the ice level sensors from the base of the ice chute and wipe the inside clean.

Remove the front panel.
Pull photo eye holders forward to release them.
Wipe clean as needed. Do not scratch the photo-eye portion.
Return the eye holders to their normal positions and return the front panel to its original position.

Note: Eye holders must be mounted properly. They snap into a centered position and are properly located when the wires are routed to the back and the left eye is the one with 2 wires at the connector.

The ice machine senses water by a probe located near the water reservoir. At least twice a year, the probe should be wiped clean of mineral build-up.

Shut off the water supply.
Remove the front panel.
Remove the hose from the water sensor using hose clamp pliers.
Loosen the mounting screw and release the water sensor from the frame of the unit.
Wipe the probes clean.

Optional adjustable ice level control (KVS). When this option is present there is an adjustment post and an additional indicator light to the right of the four indicator lights mentioned earlier.

Use of Adjustable Ice Level Control

There are several positions the ice level can be set to, including Off or Max (knob and label indicators lined up), where it fills the bin until the standard bin control shuts the machine off. See the kit’s instructions for complete details.
Rotate the adjustment post to the desired ice level. The machine will fill up to that level, and when it shuts off, the indicator light next to the adjustment post will be On.
For dispenser applications (Nugget ice only), set the adjustment knob arrow to the Norm area between the green arrows. Select either the first or second positions as a starting point and adjust as needed.

What to Do Before Calling for Service

Normal Operation

The machine will make either flaked or nugget ice, depending on the model. The ice will be produced continuously until the bin is full. It is normal for a few drops of water to occasionally fall with the ice.
For remote models, most heat is exhausted at the remote condenser, so the ice machine should not generate significant heat. Water-cooled models also put most of the heat from ice making into the discharge water. Air-cooled models will generate heat, and it will be discharged into the room.
The ice machine will make noise when it is in ice-making mode. The compressor and gear reducer will produce sound. Air-cooled models will add fan noise. Some ice-making noise could also occur. These noises are all normal for this machine.

Reasons the Machine Might Shut Itself Off

Lack of water.
Does not make ice.
Auger motor overload.
High discharge pressure.
Low refrigeration system pressure.

Check the Following

Has the water supply to the ice machine or building been shut off? If yes, the ice machine will automatically restart within minutes after water begins to flow to it.
Has power been shut off to the ice machine? If yes, the ice machine will automatically restart when power is restored.
Has someone shut the power off to the remote condenser while the ice machine still had power? If yes, the ice machine may need to be manually reset.

To Manually Reset the Machine

Open the switch door.
Push and release the Off button.
Push and release the On button.

To Shut the Machine Off
