General System Overview

The Blended Ice Machine is a self-contained dispensing unit that allows the operator to make ﬂ avor combinations of blended ice drinks. It contains product ﬂ avoring in a reach-in enclosure, a refrigeration system and an ice shaving machine.

The operator controls and accesses the unit using a lighted touch screen. Icons on the Drink Selection screen represent the primary ﬂ avor combinations for the blended ice drinks. A second screen provides drink size options (S, M, L) and ingredient options, such as “no yogurt.” Menu changes and additions are uploaded using a USB mass storage device.

On-screen instructions also include operator procedures for cleaning/sanitizing, checking inventory, replacing product bags, selecting drink sizes and manually preparing drinks. Managers and technicians have access to menu/software updates, diagnostics and other service screens.

GENERAL

Warning

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

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 Blended 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 qualiﬁ ed electrician.

ELECTRICAL REQUIREMENTS

Refer to Blended Ice Machine Model/Serial Plate for voltage/amperage speciﬁ cations. A dedicated electrical circuit is required.

Location

The location selected for the Blended Ice Machine must meet the following criteria.

• The air temperature must be at least 40°F (4°C), but must not exceed 90°F (32°C), climate class 4.

• The location must not be near heat-generating equipment or in direct sunlight and must be protected from weather.

• Water temperature min/max = 40°F/110°F (4°C/43°C).

• Water pressure min/max = 20 psi/40 psi (138kPa/276kPa)

• Always use the water supply line supplied when installing this appliance. Never reuse an old supply line.

• Main supply CO Machine regulator min/max = 55 psi/150 psi (379kPa/1034kPa)

Carbon Dioxide (CO2) displaces oxygen. Exposure to a high concentration of CO2 gas causes tremors, which are followed rapidly by loss of consciousness and suffocation. If a CO2 gas leak is suspected, particularly in a small area, immediately ventilate the area before repairing the leak. CO2 lines and pumps must not be installed in an enclosed space. An enclosed space can be a cooler or small room or closet. This may include convenience stores with glass door self serve coolers. If you suspect CO2 may build up in an area, venting of the B-I-B pumps and / or CO2 monitors must be utilized.

Maintenance

Door Gasket Maintenance

Door gaskets require regular cleaning to prevent mold and mildew build up and also to retain the elasticity of the gasket. Gasket cleaning can be done with the use of warm soapy water. Avoid full strength cleaning products on gaskets as this can cause them to become brittle and crack. Never use sharp tools or knives to scrape or clean the gasket. Gaskets can be easily replaced and do not require the use of tools or an authorized service person. The gaskets are “Dart” style and can be pulled out of the groove in the door and new gaskets can be “pressed” back into place.

Drain Maintenance - Base

Each unit has a drain located inside the unit that removes the condensation from the evaporator coil and routes it to an external condensate evaporator pan. Each drain can become loose or disconnected during normal use. If you notice water accumulation on the inside of the unit be sure the drain tube is connected to the evaporator drain pan. If water is collecting underneath the unit make sure the end of the drain tube is in the condensate evaporator in the machine compartment. The leveling of the unit is important as the units are designed to drain properly when level. Be sure all drain lines are free of obstructions.

Caster Maintenance

Wipe casters with a damp cloth monthly to prevent corrosion.

The power switch must be turned to OFF and the unit disconnected from the power source whenever performing service, maintenance functions or cleaning the refrigerated area.

Refrigerators

The interior and exterior can be cleaned using soap and warm water. If this isn’t sufﬁ cient, try ammonia and water or a nonabrasive liquid cleaner. When cleaning the exterior, always rub with the “grain” of the stainless steel to avoid marring the ﬁ nish. Do not use an abrasive cleaner because it will scratch the stainless steel and can damage the breaker strips and gaskets.

Stainless Steel Care and Cleaning

To prevent discoloration or rust on stainless steel several important steps need to be taken. First, we need to understand the properties of stainless steel. Stainless steel contains 70- 80% iron, which will rust. It also contains 12-30% chromium, which forms an invisible passive ﬁ lm over the steel’s surface, which acts as a shield against corrosion. As long as the protective layer is intact, the metal is still stainless. If the ﬁ lm is broken or contaminated, outside elements can begin to breakdown the steel and begin to form discoloration or rust. Proper cleaning of stainless steel requires soft cloths or plastic scouring pads.

NEVER USE STEEL P ADS, WIRE BRUSHES OR SCRAPERS!

Cleaning solutions need to be alkaline based or non-chloride cleaners. Any cleaner containing chlorides will damage the protective ﬁ lm of the stainless steel. Chlorides are also commonly found in hard water, salts, and household and industrial cleaners. If cleaners containing chlorides are used be sure to rinse repeatedly and dry thoroughly. Routine cleaning of stainless steel can be done with soap and water. Extreme stains or grease should be cleaned with a non-abrasive cleaner

and plastic scrub pad. Always rub with the grain of the steel. There are stainless steel cleaners available which can restore and preserve the ﬁ nish of the steels protective layer. Early signs of stainless steel breakdown are small pits and cracks. If this has begun, clean thoroughly and start to apply stainless steel cleaners in attempt to restore the passivity of the steel.

Never use an acid based cleaning solution! Many food products have an acidic content, which can deteriorate the ﬁ nish. Be sure to clean the stainless steel surfaces of ALL food products. Common items include, tomatoes, peppers and other vegetables.

Cleaning the Condenser Coil

In order to maintain proper refrigeration performance, the condenser ﬁ ns must be cleaned of dust, dirt and grease regularly. It is recommended that this be done at least every three months. If conditions are such that the condenser is totally blocked in three months, the frequency of cleaning should be increased. Clean the condenser with a vacuum cleaner or stiff brush. If extremely dirty, a commercially available condenser cleaner may be required.

Failure to maintain a clean condenser coil can initially cause high temperatures and excessive run times. Continuous operation with a dirty or clogged condenser coil can result in compressor failure. Neglecting the condenser coil cleaning procedures will void any warranties associated with the compressor and cost to replace the compressor.

Never use a high-pressure water wash for this cleaning procedure as water can damage the electrical components located near or at the condenser coil.

Doors/Hinges

Over time and with heavy use doors the hinges may become loose. If this happens tighten the screws that mount the hinge brackets to the frame of the unit. Loose or sagging doors can cause the hinges to pull out of the frame, which may damage both the doors and the hinges. In some cases this may require qualiﬁ ed service agents or maintenance personnel to perform repairs.

Do not place hot pans on/against the blue ABS liner. Do not throw items into the storage area. Failure to follow these recommendations could result in damage to the interior of the cabinet or to the blower coil. Overloading the storage area, restricting the airﬂ ow, and continuous opening and closing of the doors and drawers will hamper the units ability to maintain operational temperature.

Preventing blower coil corrosion

To help prevent corrosion of the blower coil, store all acidic items, such as pickles and tomatoes, in sealable containers. Immediately wipe up all spills.

Continuous opening and closing of the doors will hamper the unit’s ability to maintain optimum refrigeration temperature. Top section is not intended for overnight storage. Product should be removed from pans. Pans can remain in unit while empty.

Shaver Blade Replacement

WARNING: To reduce the risk of injury, unplug the unit before beginning any repair or upgrade work.

WARNING: Shaver and Blender Blades are sharp! Handle with caution to avoid injury. NOTE: Actual components may differ slightly in appearance from those shown in this Update.

1. Unplug the unit from its power source.

2. Remove the Lid and the Ice Shelf from the Ice Bin.

3. Remove the Shaver Wheel. To do so, hold the Shaver Wheel ﬁ rmly with one hand while turning the Paddle nut counterclockwise with the other hand, as shown in Figure A. If the Paddle Nut is too tight to loosen by hand, use a pair of pliers. After removing the Paddle Nut, pull the Shaver Wheel up and off of the shaft.

4. The Ice Shaver Blade should now be exposed. Remove the two screws that secure the blade, as shown in Figure B. Note that the screw holes in the Shaver blade are recessed to allow the mounting screws to ﬁ t ﬂ ush with the top surface of the blade. When installing the new Shaver Blade, be sure to mount it with the recessed side facing upward. Also note the number and type of shims underneath the blade (See Figure C.). The two different types of shims are easily distinguishable by their thickness. There may be a number of different shim combinations based on the vintage of your unit, including but not limited to one thin shim alone, one thick shim alone and one thick shim in combination with up to ﬁ ve thin shims. Be sure to note this accurately when you remove the blade.

5. The Ice Shaver Blade Replacement Kit, shown in Figure D, includes:

• (1) Shaver Blade (STM519) NOTE: The replacement Shaver Blade may differ in

appearance from the blade currently installed.

• (1) Thick Shim (STM517)

• (4) Thin Shims (STM514)

• (2) Mounting Screws (FST527) NOTE: Mounting Screws may be a different length than

the screws that you currently use.

Replace the old blade with the blade from the kit, along with the same combination of shims that existed when you removed the old blade. You can reuse the old shims or use the shims provided in the kit as long as the combination is the same as the original. Be sure to mount the blade so that the side with recessed screw holes is facing up.

6. Secure the new blade with the new screws provided. The new screws should be compatible with any shim conﬁ guration even if they are longer than the original screws.

7. Replace the shaver wheel and secure the paddle nut as tightly as possible BY HAND. No tools should be required to tighten the paddle nut.

8. MAKE SURE THAT THE PADDLE NUT IS TIGHT AND ROTATE THE SHAVER WHEEL COUNTERCLOCKWISE BY HAND. THERE SHOULD BE NO INTERFERENCE BETWEEN THE SHAVER WHEEL AND THE ICE SHAVER BLADE. IF THERE IS ANY EVIDENCE OF INTERFERENCE SUCH AS A SCRAPING NOISE OR DIFFICULTY TURNING THE SHAVER WHEEL, REMOVE THE SHAVER WHEEL AND THE ICE SHAVER BLADE. YOU CAN LOWER THE BLADE HEIGHT BY REMOVING SHIMS. START BY REMOVING THE THIN SHIMS FIRST, ONE AT A TIME. CHECK FOR INTERFERENCE AFTER REMOVING EACH SHIM. PROCEED TO THE NEXT STEP ONLY WHEN NO INTERFERENCE EXISTS. FAILURE TO ENSURE CLEARANCE CAN RESULT IN DAMAGE TO THE ICE SHAVER BLADE AND/OR THE SHAVER WHEEL.

9. Replace the ice shelf.

10. Fill the ice bin about one-third to one-half full of ice and replace the lid.

11. Plug the unit in.

12. Press the Dispense Ice Button for 10 seconds. The unit should dispense between 12 and 25 ounces of ice during the 10 second period. If the unit dispenses less than this, thin shims can be added one at a time to increase the shave rate. ALWAYS BE AWARE OF CLEARANCE BETWEEN THE SHAVER WHEEL AND THE ICE SHAVER BLADE. FAILURE TO DO SO CAN DAMAGE THE MACHINE.

Refrigeration Operation

Default temperature setpoint = 36°F (2.2°C) with a 4°F (2.2°C) Differential

Normal Operation

The microprocessor control board controls the cabinet temperature based on the input received from the cabinet temperature thermistor. The thermistor value is compared to the control board setpoint. When the reach-in temperature is equal or greater than the setpoint (plus half the differential) the compressor relay closes provided the following conditions are satisﬁ ed:

1. Power has been uninterrupted to the control board for a 3 minute period.

1. The 3 minute compressor time delay has expired. The delay period starts after the compressor has run and then cycles off.

2. The blender motor is off - If the blender motor is operating the compressor relay closes when the blender motor stops (provided # 1 above is true).

The compressor relay opens when the reach-in temperature is less than the setpoint (minus half the differential).

Evaporator and Condenser Fan Motor Operation

The condenser fan motor and compressor share the same relay. The evaporator fan motor relay is energized continuously and the evaporator fan cycles off only during cleaning cycle.

Operation in the Clean/Sanitize cycle

During the weekly cleaning/sanitize cycle the evaporator fan motor relay and the condenser fan motor/ compressor relay are de-energized. The relays cannot energize until the clean/sanitize cycle is complete. Upon completion of the clean/sanitize cycle the relays will energize provided the conditions listed in normal operation are satisﬁ ed.

Maximum Compressor Run Time

After 180 minutes of cumulative compressor run time, the compressor will be de-energized for ﬁ fteen (15) minutes.

High Temp Alarm

High temp alarm will display when product thermistor is above 42ºF (5.6°C) for 30 minutes and following conditions are satisﬁ ed

3 hours since power is applied 1 hour since cleaning cycle Error display will reset when temperature reaches 41ºF

(5°C) or below.

Thermistor Failure

If the microprocessor control board receives an open or shorted cabinet thermistor signal the following will happen:

1. A fault is displayed on the LCD screen sensor

• Cabinet sensor open OR

• Cabinet sensor shorted

1. The microprocessor will initiate a default sequence

for the refrigeration system - 12 minutes on, 3 minutes off.

2. The default cycle continues until the fault is

corrected or power is disconnected. Refer to Cabinet Temperature Thermistor for diagnostic procedures.

Compressor Electrical Diagnostics

THE COMPRESSOR DOES NOT START OR WILL TRIP REPEATEDLY ON OVERLOAD.

Check Resistance (Ohm) Values Compressor windings can have very low ohm values.

Use a properly calibrated meter. Perform the resistance test after the compressor cools.

The compressor dome should be cool enough to touch (below 120°F/49°C) to assure that the overload is closed and the resistance readings will be accurate.

Single Phase Compressors Disconnect power then remove the wires from the

compressor terminals. The resistance values between C and S and between

C and R, when added together, should equal the resistance value between S and R.

If the overload is open, there will be a resistance reading between S and R, and open readings between C and S and between C and R. Allow the compressor to cool, then check the readings again.

Check Motor Windings to Ground Check continuity between all three terminals and the

compressor shell or copper refrigeration line. Scrape metal surface to get good contact. If continuity is present, the compressor windings are grounded and the compressor should be replaced.

COMPRESSOR DRAWING LOCKED ROTOR

To determine if the compressor is seized, check the amp draw while the compressor is trying to start.

The two likely causes of this are a defective starting component and a mechanically seized compressor.

To determine which you have: Install high and low side gauges. Try to start the compressor. Watch the pressures closely. If the pressures do not move, the compressor is seized.

Replace the compressor.

DIAGNOSING CAPACITORS

If the compressor attempts to start, or hums and trips the overload protector, check the starting components before replacing the compressor.

Visual evidence of capacitor failure can include a bulged terminal end or a ruptured membrane. Do not assume a capacitor is good if no visual evidence is present.

A good test is to install a known good substitute capacitor.

Use a capacitor tester when checking a suspect capacitor. Clip the bleed resistor off the capacitor terminals before testing.

DIAGNOSING START COMPONENTS

If the compressor attempts to start, or hums and trips the overload protector, check the start components before replacing the compressor.

Capacitor Visual evidence of capacitor failure can include a bulged

terminal end or a ruptured membrane. Do not assume a capacitor is good if no visual evidence is present. A good test is to install a known good substitute capacitor. Use a capacitor tester when checking a suspect capacitor. Clip the bleed resistor off the capacitor terminals before testing.

Relay The relay has a set of contacts that connect and

disconnect the start capacitor from the compressor start winding. The contacts on the relay are normally open. The relay senses the voltage generated by the start winding and closes and then opens the contacts as the compressor motor starts. The contact remain open until the compressor is de-energized.

If the pressures move, the compressor is turning slowly and is not seized. Check the capacitors and relay.

Compressor Drawing High Amps The continuous amperage draw on start-up should not

be near the maximum fuse size indicated on the serial tag.

Important

Multiplex assumes no responsibility for the use of contaminated refrigerant. Damage resulting from the use of contaminated refrigerant is the sole responsibility of the servicing company.

Important

Replace the liquid line drier before evacuating and recharging. Use only a Multiplex (O.E.M.) liquid line ﬁ lter drier to prevent voiding the warranty

Connections

• Blended Ice Machines are critically charged. There are no refrigerant access ports.

• Locate the high and low side process tubes.

• Install a piercing valve (saddle valve) on both the high and low side process tubes.

• Remove piercing valves after charging. Unit is critically charged.

• Purge system with nitrogen while brazing to prevent build up of copper oxide in the refrigeration system.

• Manifold gauges must be removed properly to ensure that no refrigerant contamination or loss occurs. A quick disconnect is required for the high side connection unless high side valve has shut off.

Recovery/Evacuation

1. Place the rocker switch in the OFF position.

2. Install manifold gauges, charging scale, and recovery unit or two-stage vacuum pump.

3. Open the high and low side valves on manifold gauges.

4. Perform recovery or evacuation:

5. Recovery: Operate the recovery unit as directed by the manufacturer’s instructions.

6. Evacuation prior to recharging: Pull the system down to 500 microns. Then, allow the pump to run for an additional half hour. Turn off the pump and perform a standing vacuum leak check.

7. Check for leaks using an electronic leak detector after charging the Blended Ice Machine.

Refrigerant Recovery/Evacuation & Charging Procedures

Charging Procedures

The charge is critical on all Multiplex Blended Ice Machine. Use a scale to ensure the proper charge is installed. A quick disconnect is required for the high side connection.

1. Be sure the rocker switch is in the OFF position.

2. Close the vacuum pump valve and the low side manifold gauge valve.

3. Open the high side manifold gauge valve.

4. Open the refrigerant cylinder and add the proper refrigerant charge (shown on nameplate) through the discharge service valve.

5. Close the high side on the manifold gauge set. Add any remaining vapor charge through the suction access ﬁ tting (if necessary).

6. Let the system “settle” for 2 to 3 minutes.

7. Place the rocker switch in the ICE position.

NOTE: Manifold gauges must be removed properly to ensure that no refrigerant contamination or loss occurs.

1. Make sure that all of the vapor in the charging hoses is drawn into the Blended Ice Machine before disconnecting the charging hoses.

• Run the Blended Ice Machine in the freeze cycle.

• Verify the refrigerant cylinder valve is closed.

• Open the high and low side valves on the manifold

gauge set. Any refrigerant in the lines will be pulled into the low side of the system.

• Allow the pressures to equalize while the Blended

Ice Machine is in the freeze cycle.

• Close the high and low side manifold gauge set.

• Remove the hoses from the Blended Ice Machine

and install the caps.

System Contamination Cleanup

General This section describes the basic requirements for

restoring contaminated systems to reliable service.

Important

Multiplex assumes no responsibility for the use of contaminated refrigerant. Damage resulting from the use of contaminated refrigerant is the sole responsibility of the servicing company.

DETERMINING SEVERITY OF CONTAMINATION

System contamination is generally caused by either moisture or residue from compressor burnout entering the refrigeration system.

Inspection of the refrigerant usually provides the ﬁ rst indication of system contamination. Obvious moisture or an acrid odor in the refrigerant indicates contamination.

If either condition is found, or if contamination is suspected, use a Total Test Kit from Totaline or a similar diagnostic tool. These devices sample refrigerant, eliminating the need to take an oil sample. Follow the manufacturer’s directions.

If a refrigerant test kit indicates harmful levels of contamination, or if a test kit is not available, inspect the compressor oil.

1. Remove the refrigerant charge from the Blended Ice Machine.

2. Remove the compressor from the system.

3. Check the odor and appearance of the oil.

4. Inspect open suction and discharge lines at the compressor for burnout deposits.

5. If no signs of contamination are present, perform an acid oil test to determine the type of cleanup required.

CONTAMINATION/CLEANUP CHART

Symptoms/Findings

Required Cleanup Procedure

• No symptoms or suspicion of contamination

Normal evacuation/recharging procedure

• Moisture/Air Contamination symptoms Refrigeration test kit and/or acid oil test shows contamination Refrigeration system open to atmosphere for longer than 15 minutes No burnout deposits in open compressor lines

Mild contamination cleanup procedure

• Mild Compressor Burnout symptoms Oil appears clean but smells acrid Refrigeration test kit or acid oil test shows harmful acid content No burnout deposits in open compressor lines

Mild contamination cleanup procedure

• Severe Compressor Burnout symptoms Oil is discolored, acidic, and smells acrid Burnout deposits found in the compressor, lines, and other components

Severe contamination cleanup procedure

Mild System Contamination Cleanup Procedure

1. Replace any failed components.

2. If the compressor is good, change the oil.

3. Replace the liquid line drier.

NOTE: If the contamination is from moisture, use heat lamps during evacuation. Position them at the compressor, condenser and evaporator prior to evacuation. Do not position heat lamps too close to plastic components, or they may melt or warp.

Dry nitrogen is recommended for this procedure. This will prevent CFC release.

1. Follow the normal evacuation procedure, except replace the evacuation step with the following:

• Pull vacuum to 1000 microns. Break the vacuum

with dry nitrogen and sweep the system. Pressurize to a minimum of 5 psig (34kPa).

• Pull vacuum to 500 microns. Break the vacuum with

dry nitrogen and sweep the system. Pressurize to a minimum of 5 psig (34kPa).

• Change the vacuum pump oil.

• Pull vacuum to 500 microns. Run the vacuum pump

for 1/2 hour .

NOTE: You may perform a pressure test as a preliminary leak check. You should use an electronic

leak detector after system charging to be sure there are no leaks.

1. Charge the system with the proper refrigerant to the nameplate charge.

2. Operate the Blended Ice Machine.

Severe System Contamination Cleanup Procedure

1. Remove the refrigerant charge.

2. Remove the compressor.

3. Wipe away any burnout deposits from suction and discharge lines at compressor.

4. Sweep through the open system with dry nitrogen.

NOTE: Refrigerant sweeps are not recommended, as they release CFCs into the atmosphere.

5. Install a new compressor and new start components.

6. Install suction line ﬁ lter-drier in front of compressor.

7. Install a new liquid line drier.

8. Follow the normal evacuation procedure, except replace the evacuation step with the following:

• Pull vacuum to 1000 microns. Break the vacuum

with dry nitrogen and sweep the system. Pressurize to a minimum of 5 psig (34 kPa).

• Change the vacuum pump oil.

• Pull vacuum to 500 microns. Break the vacuum with

dry nitrogen and sweep the system. Pressurize to a minimum of 5 psig (34 kPa).

• Change the vacuum pump oil.

• Pull vacuum to 500 microns. Run the vacuum pump

for 1 additional hour.

9. Charge the system with the proper refrigerant to the nameplate charge.

10. Operate the refrigeration system for one hour. Then, check the pressure drop across the suction line ﬁ lter-drier.

• If the pressure drop is less than 2 psig (14 kPa), the

ﬁ lter-drier should be adequate for complete cleanup.

• If the pressure drop exceeds 2 psig (14 kPa),

change the suction line ﬁ lter-drier and the liquid line drier. Repeat until the pressure drop is acceptable.

• Operate the refrigeration system for 48 – 72 hours.

Replace the suction line and liquid line drier if necessary.

R-290 Service Procedure

1. All service work must be performed by personnel qualiﬁ ed to handle ﬂ ammable refrigerants.

2. NO SMOKING

3. Disconnect all power to the unit being serviced.

4. Move the unit to be serviced to a well ventilated area.

5. Check for leaks using a calibrated Hydro Carbon leak detector.

6. Keep all electrical equipment and other sources of ignition back 10’ (two meters).

7. Follow the Recovery/Evacuation procedure above to repair the refrigeration system.

Filter-Driers

A Multiplex ﬁ lter-drier has high moisture and acid removal capability.

The size of the ﬁ lter-drier is important. The refrigerant charge is critical. Using an improperly sized ﬁ lter-drier will cause the Blended Ice Machine to be improperly charged with refrigerant.

Drier DML-032S, 1/4” (.64cm) end connection is the recommended OEM ﬁ eld replacement drier.

Driers are covered as a warranty part. The drier must be replaced any time the system is opened for repairs.

Total System Refrigerant Charge
