Ice machines, like other refrigeration equipment, reject heat through the condenser. It is helpful to know the amount of heat rejected by the ice machine when sizing air conditioning equipment where self-contained air-cooled ice machines are installed.

This information is also necessary when evaluating the benefits of using water-cooled or remote condensers to reduce air conditioning loads. The amount of heat added to an air conditioned environment by an ice machine using a watercooled or remote condenser is negligible.

Knowing the amount of heat rejected is also important when sizing a cooling tower for a water-cooled condenser. Use the peak figure for sizing the cooling tower.

Installing on a Storage Bin

LEVELING THE ICE STORAGE BIN

1. Screw the leveling legs onto the bottom of the bin.

2. Screw the foot of each leg in as far as possible.

The legs must be screwed in tightly to prevent them from bending.

3. Move the bin into its final position.

4. Level the bin to assure that the bin door closes and seals properly. Use a level on top of the bin. Turn each foot as necessary to level the bin.

5. Inspect bin gasket prior to ice machine installation. (Manitowoc bins come with closed cell foam gasket installed along the top surface of the bin.)

6. Install ice machine on bin.

Installing on a Dispenser

Nugget ice is soft and chewable. This characteristic makes this ice more difficult to dispense. All dispenser manufacturers require a kit be installed for Nugget type ice. Contact the dispenser manufacturer for the correct adapter and nugget dispensing kit for your specific model dispenser . Th e requir ed kit can var y by dispen ser size from the same manufacturer.

Failure to install the correct kit and make the necessary modifications on the dispenser will result in:

• Congealed ice which will not dispense and will damage the ice machine and dispenser

• Insufficient ice contact with the cold plate which will result in an inferior product

• A safety issue if ice lifts the adapter or ice machine

NUGGET DISPENSING KIT INSTALLATION PROCEDURE

1. Follow the dispenser manufacturers instructions for installation of the adapter (if required) and nugget ice kit.

2. Make all necessary beverage, electrical and drain connections to the dispenser.

Leveling Leg and Foot

3. Level the dispenser front to back and side to side.

4. Install ice machine on dispenser and secure ice machine, dispenser and adapter with provided brackets.

5. Complete water, drain and electrical connections to the ice machine.

PERSONAL INJURY POTENTIAL

The ice machine and adapter must be attached to the dispenser to prevent the ice machine from falling.

Ice machines in low volume locations may experience congealing. Thermostat kit K00364 must be added in these locations to prevent damage to the ice machine and dispenser.

Electrical Service

RFC Condensing Units: Energize the head

All wiring must conform to local, state and national codes.

VOLTAGE

The maximum allowable voltage variation is ±1 0% of the rated voltage at ice machine star t-up (when the electrical load is highest).

The ice machine must be grounded in accordance with national and local electrical codes.

All electrical work, including wire routing and grounding, must conform to local, state and national electrical codes. The following precautions must be observed:

• The ice machine must be grounded.

• A separate fuse/circuit breaker must be provided for each ice machine.

• A qualified electrician must determine proper wire size dependent upon location, materials used and length of run (minimum circuit ampacity can be used to help select the wire size).

• The maximum allowable voltage variation is +/-10 of the rated voltage at ice machine start-up (when the electrical load is highest).

• Check all green ground screws in the control box and verify they are tight before starting the ice machine.

Observe correct polarity of incoming line voltage.

Incorrect polarity can lead to erratic ice machine operation and a safety issue. This is especially cr itical on 230 volt / 50 cycle ice machines.

FUSE/CIRCUIT BREAKER

A separate fuse/circuit breaker must be provided for each ice machine. Circuit breakers must be H.A.C.R. rated (does not apply in Canada).

MINIMUM CIRCUIT AMPACITY

The minimum circuit ampacity is used to help select the wire size of the electrical supply. (Minimum circuit ampacity is not the ice machine’s running amp load.)

The wire size (or gauge) is also dependent upon location, materials used, length of run, etc., so it must be determined by a qualified electrician.

GROUND FAULT CIRCUIT INTERUPTER

Ground Fault Circuit Interupter (GFCI/GFI) protection is a system that shuts down the electric circuit (opens it) when it senses an unexpected loss of power, presumably to ground. Manitowoc Ice, Inc. does not recommend the use of a GFCI/GFI circuit protection with our equipment. If code requires the us e of a GF CI /G FI then you must follow the local code. The circuit must be dedicated, sized properly and there must be a panel GFCI/GFI breaker. We do not recommend GFCI/GFI outlets as they are known for more intermittent n uisance trips than panel breakers.

SF900C/SN0950C/SF1200C/SN1250C with Remote Condensing Unit the ice machine head section and

remote condensing unit are wired independent of each other. A sep arate dedicated fuse /circuit brea ker must be provided for each section. Circuit breakers must be H.A.C.R. rated (does not apply in Canada).

Water Supply and Drains

POTABLE WATER SUPPLY

Local water conditions may require treatment of the water to inhibit scale formation, filter sediment, and remove chlorine odor and taste.

If you are installing a Manitowoc water filter system, refer to the Installation Instructions supplied with the filter system for ice making water inlet connections.

POTABLE WATER INLET LINES

Follow these guidelines to install water inlet lines:

• Do not connect the ice machine to a hot water supply. Be sure all hot water restrictors installed for other equipment are working. (Check valves on sink faucets, dishwashers, etc.)

• If water pressure exceeds the maximum (80 psig

5.52 bar) recommended pressure, obtain a water pressure regulator from your Manitowoc distributor.

• Install a water sh ut-off valve and union for both the ice making and condenser water lines.

• Insulate water inlet lin es to prevent condensation.

DRAIN CONNECTIONS

Follow these guidelines when installing drain lines to prevent drain water from flowing back into the ice machine and storage bin:

• Drain lines must have a 1.5 inch drop per 5 feet of run (2.5 cm per meter), and must not create traps.

• The floor drain must be large enough to accommodate drainage from all drains.

• Run separate bin and water-cooled condenser drain lines. Insulate them to prevent condensation.

• Vent the bin and ice machine drain to the atmosphere. The ice machine drain requires an 18” vent. Do not vent the condenser drain on watercooled models.

• Drains must have a union o r other suitable means to allow in place disconnection from the ice machine when servicing is required.

Cooling Tower Applications (Water-Cooled Models)

A water cooling tower installation does not require modification of the ice machine. The water regulator valve for the condenser continues to control the refrigeration discharge pressure.

It is necessary to know the amount of heat rejectio n, and the pressure drop through the condenser and water valves (inlet and outlet) when using a cooling tower on an ice machine.

• Water entering the condenser must not exceed 90°F (32°C).

• W ater flow through the condenser must n ot exceed 5 gallons (19 liters) per minute.

• Allow for a pressure drop of 7 ps i (0.48 bar) between the condenser water inlet and the outlet of the ice machine.

• Water exiting the condenser must not exceed 110°F (43°C).

The Commonwealth of Massachusetts requires that all water-cooled models must be connected only to a closed loop, cooling tower system.

Refrigeration Line Set Installation Traditional Remote Ice Machines Only

GENERAL

Condensers must be mounted horizontally with the fan motor on top.

Remote condenser installations consist of vertical and horizontal line sets between the ice machine and the condenser. When co mbined, they must fit within approved specifications. The following guidelines, drawings and calculation methods must be followed to verify a proper remote condenser installation.

The 60 month compressor warranty (including the 24 month labor replacement warranty) will not apply if the remote ice machine is not installed according to specifications.

This warranty also will not apply if the refrigeration system is modified with a condenser, heat reclaim device, or other parts or assemblies not manufactured by Manitowoc Ice, Inc., unless specifically approved in writing by Manitowoc Ice, Inc.

GUIDELINES FOR ROUTING LINE SETS

First, cut a 2.5" (6.35 cm) circular hole in the wall or ro of for tubing routing. The line set end with the 90° bend will connect to the ice machine. The straight end will connect to the remote condenser.

Follow these guidelines when routing the refrigerant lines. This will help insure proper performance and service accessibility.

1. Optional - Make the service loop in the line sets (as shown below). This permits easy access to the ice machine for cleaning and service. Do not use hard rigid copper at this location.

2. Required - Do not form traps in the refrigeration lines (except the service loop). Refrigerant oil must be free to drain toward the ice machine or the condenser. Route excess tubing in a supported downward horizontal spiral (as shown below). Do not coil tubing vertically.

3. Required - Keep outdoor refrigerant line runs as short as possible.

CALCULATING REMOTE CONDENSER INSTALLATION DISTANCES

Line Set Length

The maximum length is 100' (30.5 m). The ice machine compressor must have the proper oil

return. The receiver is designed to hold a char ge sufficient to operate the ice machine in ambient temperatures between -20°F (-29°C) and 120°F (49°C), with line set lengths of up to 100' (30.5 m).

Line Set Rise/Drop

The maximum rise is 35' (10.7 m). The maximum drop is 15' (4.5 m).

If a line set has a rise followed by a drop, another rise cannot be made. Likewise, if a line set has a drop followed by a rise, another drop cannot be made.

Calculated Line Set Distance

The maximum calculated distance is 150' (45.7 m). Line set rises, drops, horizontal ru ns (or combinations of

these) in excess of the stated maximums will exceed compressor start-up and design limits. This will cause poor oil return to the compressor.

Make the following calculations to make sure the line set layout is within specifications.

1. Insert the measured rise into the formula below. Multiply by 1.7 to get the calculated rise. (Example: A condenser located 10 feet above the ice machine has a calculated rise of 17 feet.)

2. Insert the measured drop into the formula below. Multiply by 6.6 to get the calculated drop. (Example. A condenser located 10 feet below the ice machine has a calculated drop of 66 feet.)

3. Insert the measured horizontal distance into the formula below. No calculation is necessary.

4. Add together the calculated rise, calculated drop, and horizont al distance to get the total calculated distance. If this total exceeds 150' (45.7 m), move the condenser to a new location and perform the calculations again.

Step 1. Measured Rise (35' [10.7 m] Maximum) ______ x 1.7 = _______ Calculated Rise Step 2. Measured Drop (15' [4.5 m] Maximum) ______ x 6.6 = _______ Calculated Drop Step 3. Measured Horizontal Distance (100' [30.5 m] Maximum) _______ Horizontal Distance Step 4. Total Calculated Distance 150' (45.7 m) _______ Total Calculated Distance

LENGTHENING OR REDUCING LINE SET LENGTHS

In most cases, by routing the line set properly, shortening will not be necessary. When shortening or lengthening is required, do so before connecting the line set to the ice machine or the remote condenser. This prevents the loss of refrigerant in the ice machine or condenser.

The quick connect fittings on the line sets are equipped with Schraeder valves. Use these valves to recover any vapor charge from the line set. When lengthening or shortening lines follow good refrigeration practices, purge with nitrogen and insulate all tubing. Do not change the tube sizes. Evacuate the lines and place about 5 oz (143g) of vapor refrigerant charge in each line.

CONNECTING A LINE SET

1. Remove the dust caps from the line set, condenser and ice machine.

2. Apply refrigeration oil to the threads on the quick disconnect couplers before connecting them to the condenser.

3. Carefully thread the female fitting to the condenser or ice machine by hand.

4. Tighten the couplings with a wrench until they bottom out.

Refrigeration Line Set Installation Remote Condensing Unit Only

GENERAL

Refrigeration line set installations consist of vertical and horizontal line set distances between the ice machine and the condensing unit. The following guidelines, drawings and calculation methods must be followed to assure proper oil return and remote condensing unit/ice machine operation.

The refrigeration line set installer must be USA Government-Environmental Protection Agency (EPA) certified in proper refrigerant handling and servicing procedures.

The ice machine head section contains refrigerant charge. The ice machine he ad sectio n contains thre e (3) refrigeration valves that must remain closed until proper installation of the line sets is completed.

Disconnect electrical power to the ice machine head section and remote condensing unit before proceeding.

A. LINE SET LENGTH 100 feet (30.5 m) Length: The maximum measured

length the line set can be. The receiver is designed to hold a charge sufficient to

operate the ice machine in ambient temperatures between -20°F (-28.9°C) and 130°F (54.4°C), with line set lengths of up to 100 feet (30.5 m).The maximum amount of lineset which can be exposed on the rooftop is 25% of the total length of the lineset.

QuietQube® ice machines will not function with line sets greater than 100 feet (30.5 m). Do not attempt to go beyond this distance and add refr igera nt ch ar ge to compensate!

B. LINE SET RISE OR DROP

Step 1 Verify Ice Machine and Remote Condensing

Unit Locations Are Within Guidelines.

Prior to installation of the ice machine head section and remote condensing unit be sure that the distance between then is within the line set routing guidelines outlined in this manual.

Roof/Wall Penetration

If required, cut a 3-inch (76.2 mm) circular hole in the wall or roof for routing of refrigeration tubing. A qualified person must perform all roof penetrations.

Step 2 Route Refrigeration Tubing

Properly route refrigeration tubing between the ice machine head section and the remote condensing unit.

35 feet (10.7 m) Rise: The maximum distance the remote condensing unit can be above the ice machine.

15 feet (4.5 m) Drop: The maximum distance the remote condensing unit can be below the ice machine.

0 to 20 feet (0 to 6.1 m) Rise: The ice machine head section has one oil trap built in which allows for a maximum condenser rise of 20 feet (6.1 m) without additional traps in the suction line.

21 to 35 feet (6.4 to 10.7 m) Rise: The suction line requires an additional Oil Trap (“S” type) to be installed. Install the trap as close as possible to midpoint between the ice machine head section and remote condensing unit. S-Trap Kits are available from Manitowoc (refer to chart).

Service Loop

A service loop in the line set permits easy access to the ice machine for cleaning and service.

• A service loop is not considered an oil trap.

• The service loop is not included when calculating length, rise or drop of the tubing run.

• Do not use hard rigid copper for the service loop.

If a line set has a rise followed by a drop, another rise cannot be made. Likewise, if a line set has a drop followed by a rise, another drop cannot be made.

Step 3 Lengthening or Reducing Line Set Lengths

Do not form unwanted traps in refrigeration lines. Never coil excess refrigeration tubing.

When the line set required shortening or lengthening, do so before connecting the line set to the ice machine head section or the remote condensing unit.

Step 4 Connecting the line set.

To prevent oxidation of the copper, purge line set and condensing unit with dry nitrogen while brazing.

Connect The Line Set To The Ice Machine Head Section

The line set shut off valves at the back of the ice machine must remain closed and be protected from heat during the brazing process. Wrap the valves in a wet rag or other type of heat sink prior to brazing. Cool braze joint with water immediately after brazing to prevent heat migration to the valve.

Connect the Line Set to the Remote Condensing Unit

The condensing unit ships from the factory pressurized with a 50/50 mixture of nitrogen/helium. Bleed off pressure from both suction and liquid line access ports prior to cutting into refrigeration lines.

The compressor oil rapidly absorbs moisture. Be prepared to complete line set installation and start your evacuation process in order to minimize the time the compressor is exposed to the atmosphere. (Maximum amount of time the system can be exposed to the atmosphere is 15 minutes). The line set can be routed for entry through the front or left side of the condensing unit.

Remove knockout for (side entry only).

• Insert supplied plastic bushings in knockout holes to prevent tubing from contacting sheet metal.

• All entry locations use the supplied 90° elbows to route tubing.

• Cut the tubing ends of the suction and liquid lines and braze the line sets to the condensing unit.

Step 5 Pressure Test and Evacuate The Line Set

and Remote Condensing Unit

Schrader valve core removal tools that allow for removal and installation of the valve cores without removing manifold gauge set hoses are recommended to decrease the evacuation time.

Leave the line set shut off valves closed (front seated). Pressure test the line sets and remote condensing unit with 150 psig of dry nitrogen. Add nitrogen at the line set shut off valves located at the back of the ice machine. Complete the pressure test, verify no leaks are present and remove the nitrogen from the system before connecting the vacuum pump. Connect a vacuum pump to both of the line set shut off valves located at the back of the ice machine head section. Evacuate to 250 microns (or less). To completely evacuate the remote condensing unit, continue the evacuation for 30 minutes after reaching the 500 micron point.

If required, the line set and condensing unit can be evacuated from the schrader valves located in the remote condensing unit. Schrader valve core removal tools (that allow for putting the cores back in without removing vacuum pump hoses) must be used if evacuating from the condensing unit side.

Isolate the vacuum pump from the line set shut off valves and/or condensing unit access ports prior to proceeding. Open refrigeration system shut off valves.

The suction line, liquid line and receiver service valves are closed during shipment and installation.

Section 3 Operation

Sequence of Operation

PRIOR TO STARTUP

When the toggle switch is placed in the ICE position the following must occur in the listed order before ice making will start.

• The 5 minute delay period must be expired. The delay period starts upon application of power.

• The ice chute damper must be in th e closed or do wn position.

• The water sensing switch must be closed (water reservoir full of water and water sensing float in the up position).

1. Initial Startup - The ice machine is plugged in

and the toggle switch is moved to ice.

A 5 minute delay period must expire. The delay period starts to time out upon application of power and can not be overridden. When the five minute delay period expires, the gear motor energizes. The water in the reservoir closes the water sensing (float) switch and the compressor and condenser fan motor energize.

2. Freeze Cycle

The float valve automatically maintains the water level in the reservoir. The ice damper will open and close to verify ice production. The ice machine will continue to make ice until the ice damper is held open (up) as ice fills the bin.

3. Automatic Shutoff

RESTART AFTER AUTOMATIC SHUTOFF

The 5 minute delay period must be expired. The delay period starts when the ice machine enters Automatic Shutoff and can not be overridden.

1. The ice machine was off for less than 30 minutes.

When the five minute delay period expires the gear motor, compressor and condenser fan motor energize.

2. The ice machine was off for more than 30 minutes.

The gear motor and dump valve energize to drain the water from the evaporator and reservoir. After 30 seconds the dump valve de-energizes. When the reservoir fills with water, the water sensing switch closes and the compressor and condenser fan motor energize.

CHANGING TOGGLE SWITCH POSITION IN THE FREEZE CYCLE

Moving the toggle switch from ICE to OFF will start a 5 minute delay period.

• Moving the toggle switch immediately to the ICE

position - The ice machine waits 5 minutes, then initiates a Restart After Automatic Shutoff cycle.

• Moving the toggle switch to the ICE position after 5

minutes have elapsed - The ice machine immediatel y initiates a Restart After Automatic Shutoff cycle.

When the ice damper is held open by ice, the gearmotor, compressor and condenser fan de-energize. The five minute delay period starts to time out. The ice machine will remain off until the 5 minute delay period expires and the ice damper closes.

Control Board Features

FLUSH CYCLE

After the ice machine has completed 50 hours of run time a flush sequence will start. This cycle will drain and refill the evaporator to remove minerals that have settled to the bottom of the evaporator. The flush sequence lasts approximately 21 minutes, after which the ice machine will reset the 50 hour counter and automatically start ice making again.

POWER INTERRUPTION DELAY

If power is disconnected the ice machine stops. When power is reapplied a 5 minute delay is initiated.

SafeGuards

The ice machine control board has safety features to protect the ice machine from severe failures. The ice machine will stop when conditions arise that would cause major component failure. Refer to sectio n 5 fo r details.

Maintenance Section 4

Manitowoc’s Cleaning Technology

Manitowoc Flake/Nugget Ice Machines include technology that allows the initiation and completion of a cleaning cycle at the flip of a switch. This cycle will permit cleaning of all surfaces that come in contact with the water distribution system. Periodic maintenance must be performed that includes sanitizing the bin and adjacent surface areas, which are not contacted by the water distribution system.

Depending on local water conditions Manitowoc recommends initiating preventative maintenance cleaning procedures between the 6 month cleanings. This preventive maintenance removes mi n era l build -u p from the evaporator, which results in peak efficiency and lower operating costs.

This technology allows initiation and completion of a clean cycle, after which the ice machine automatically starts ice making again.

This Manitowoc Ice Machine has three separate cleaning procedures.

Preventative Maintenance Cleaning Procedure

Perform this procedure as required for your water conditions. Recommended monthly.

• Allows cleaning the ice machine without removing all of the ice from the bin

• Removes mineral deposits from areas or surfaces that are in direct contact with water during the freeze cycle (reservoir, evaporator, auger, drain lines).

Cleaning/Sanitizing Procedure

This procedure must be performed a minimum of once every six months.

• All ice must be removed from the bin

• The ice machine and bin must be disassembled cleaned and sanitized

• The ice machine produce s ice with the cleaner and sanitizer solutions

• All ice produced during the cleaning and sanitizing procedures must be discarded

Heavily Scaled Cleaning Procedure

Perform this procedure if you have some or all of these symptoms.

• Grinding, popping or squealing noises from the evaporator

• Grinding noise from gearbox

• Ice machine stops on Safety Shutdown

• Your water has a high concentration of minerals

• The ice machine has not been on a regular maintenance schedule.

Run a cleaning procedure as described above after this procedure is complete.

Cleaning the Condenser

Disconnect electric power to the ice machine and the remote condenser at the electric service switch before cleaning the condenser.

Air-Cooled Condenser

(SELF-CONT AINED AND REMOTE MODELS) A dirty condenser restricts airflow, resulting in

excessively high operating temperatures. This reduces ice production and shortens component life. Clean the condenser at least every six months. Follow the steps below.

The condenser fins are sharp. Use care when cleaning them.

1. The washable filter on self-contained ice machines is designed to catch dust, dirt, lint and grease. This helps keep the condenser clean. Clean the filter with a mild soap and water solution.

2. Clean the outside of the condenser with a so f t brush or a vacuum with a brush attachment. Clean from top to bottom, not side to side. Be careful not to bend the condenser fins.

Water-Cooled Condenser

and Water Regulatin g Valve

Symptoms of restrictions in the condenser water circu it include:

• Low ice production

• High water consumption

• High operating temperatures

• High operating pressures If the ice machine is experiencing any of these symptoms,

the water-cooled condenser and water regulating valve may require cleaning due to scale build-up.

Because the cleaning procedures require special pump s and cleaning solutions, qualified maintenance or service personnel must perform them.

3. Shine a flashlight through the condense r to check for dirt between the fins. If dirt remains:

A. Blow compressed air through the condenser fins

from the inside. Be careful not to bend the fan blades.

B. Use a commercial condenser coil cleaner.

Follow the directions and cautions supplied with the cleaner.

4. Carefully wipe off the fan blades and motor with a soft cloth. Do not bend the fan blades. If the fan blades are excessively dirty, wash with warm, soapy water and rinse thoroughly.

If you are cleaning the condenser fan blades with water, cover the fan motor to prevent water damage.

Safeguard Feature

In addition to standard safety controls, your Manitowoc ice machine features built-in SafeGuards. The ice machine will stop when conditions arise that would cause major component failure.

GENERAL

The ice machine control board has safety features to protect the ice machine from severe failures. The ice machine will stop when conditions arise that would cause major component failure.

A control board light will flash to indicate which Safeguard has stopped the ice machine.

Safeguards can be viewed by placing the ICE/OFF/ CLEAN toggle switch in the OFF position.

After 48 hours a Safeguard is automatically erased.

DETERMINING WHICH SAFEGUARD STOPPED THE ICE MACHINE

Move the ICE/OFF/CLEAN toggle switch to OFF. If a safeguard has stopped the ice machine, the light

which corresponds to the failure will flash.

SAFEGUARD INDICATOR LIGHTS

During a SafeGuard Mode the corresponding light will flash continuously.

Example; the “water ok” light on the control board flashes when the toggle switch is placed in the Off position. This indicates a loss of water in the reservoir or a failure of the water sensing switch.

The SafeGuard will remain in memory for 48 hours after the control is reset with the toggle switch. After 48 hours the SafeGuard will automatically be erased. If power is interrupted during the 48 hours, the timing will resume when power is applied to the ice machine.

SafeGuards

1. No Water - The water sensor switch opens for more than 20 seconds during the freeze cycle.

2. No Ice Production - The damper door (HES1) fails to open and close at least once during the first 8 minutes of compressor run time.

The damper door fails to open and close at least once every 90 seconds during the freeze cycle.

RESET PROCEDURE

1. Move the ICE/OFF/CLEAN toggle switch to OFF and then back to ICE.

A. If a safeguard feature has stopped the ice

machine, it will restart after a short delay. Proceed to step 2.

B. If the ice machine does not restart, refer to “Ice

Machine Does Not Operate” in section 5.

2. Allow the ice machine to run to determine if the problem still exists.

A. If the ice machine continues to run, the condition

has corrected itself. Allow the ice machine to continue running.

B. If the ice machine stops again, the problem still

exists.

Placing the toggle switch in the OFF position:

The corresponding light will flash continuously.

Placing the toggle switch in the ICE position:
