Multiplex Refrigeration Units are designed to operate properly on 90 psi (6.4 bar) of CO

2 pressure.

Clean Water

Carbonated drinks are made up of over 83% water. Clean water is required for good taste and to protect the equipment.

Cold Temperature

Multiplex Refrigeration Units use a cold carbonation system, water is carbonated in an ice cold water bath. It is very important to dispense drinks below 39°F (4°C).

Proper Agitation

Multiplex carbonation systems are designed to give you the exact amount of agitation to give you the proper carbonation.

Complete System Overview

Multiplex Post-mix Beverage System

Multiplex Post-mix beverage systems use filtered water from a filtered water supply system and chill it as it passes through stainless steel cooling coils located in an ice cold water bath.

The water bath is maintained at 32°F (0°C) by a mechanical refrigeration system which produces a large ice bank reserve to provide sufficient cooling for peak draw periods. This ice reserve allows a relatively small refrigeration unit to maintain drink temperatures, drawing form the ice reserve during heavy load periods and then re-establishing the ice bank during light draw periods.

The chilled water passing through the water bath is mixed with carbon dioxide (CO

2

) in the

carbonated water supply system. This is when and where it becomes carbonated water in the carbonation tank.

Syrup is also chilled as it passes through stainless steel cooling coils located in the ice cold water bath. Chilled, the syrup is connected to one of several beverage tubes contained within a

beverage conduit. This conduit is then routed to a dispensing station.

The circulating carbonated water supply system allows for the circulation of carbonated water through use of a pump to create an outlet and inlet carbonated water supply. Outlet and inlet carbonated water supplies are connected to tubes contained within the same beverage conduit as the syrup. This allows carbonated water to flow from the water bath to the dispensing station and back, maintaining a constant beverage temperature throughout the system.

Ice cold carbonated water and syrup are dispensed from valves at the dispensing station.

Dispensing valves contain flow controls which allow for flow adjustment to maintain the proper ratio of syrup to carbonated water. Syrup and carbonated water are released when the dispensing valves are opened. This allows mixing to begin as escaping products are allowed to flow through the valve nozzle. They continue to mix as they fall into the customer’s cup to complete the production of a bottler-quality soft drink.

Complete System Overview

Water Filter System

Incoming water pressure is to be maintained at 55 psig (3.9 bar) to ensure proper flow throughout the system. An in-line water regulator and gauge controls high water pressure and allows for pressure monitoring.

Water enters the pre-filter(s) that remove the coarse particles that are contained in the supply water, protecting the fine filter.

Water flows from the pre-filter(s) to the taste/odor activated carbon filter, absorbing taste and odor causing chemicals, such as chlorine and sulfur.

Finally, water runs through a fine filter, filtering out the finer particles left in the supply water, thus protecting the equipment and helping to insure quality water for carbonation.

Pressure gauges located before and after the filtration system allow the monitoring of pressure across the filter system, indicating clogged filters and the need for replacement.

Carbonation System

Carbonator Pump “off”

Carbon dioxide (CO

2

) regulated to 90 psi (6.3 bar) passes through a single check valve, which prevents water from backing up into the CO

2

supply, and fills the carbonator tank with CO

2

.

The incoming filtered water at 55 psig (3.9 bar) feeds the brass carbonator pump, then proceeds through a stainless steel cooling coil located in the 32°F (0°C) water bath. Chilled water is then delivered to the double check valve on top of the carbonator tank. CO

2

is prevented from leaving the carbonator tank through the fresh water supply by the double check valve.

When the carbonator motor is “off”, the high CO

2

pressure within the carbonator tank prevents replacement water from entering the carbonator tank.

Carbonator Pump “on”

When the carbonated water level in the carbonator tank falls below both the electrodes, the

liquid level control will send electricity to the carbonator motor. The motor turns the carbonator pump, which increases the water pressure from 55 psig (3.8 bar) to approximately 140 to 170 psig

(10 to 12 bar). This boosted water goes through the cooling coil in the water bath, through the double check valve and overcomes the 90 psig (6.3 bar) CO

2

pressure within the carbonator tank.

Water flowing through the orifice at the base of the check valve is broken into tiny droplets and sprayed into the carbonator tank, absorbing CO

2

to produce cold, quality carbonated water.

While the motor and pump is running, the carbonated water level in the tank will rise until it reaches the low and then the high electrode, at which point the liquid level control will shut “off” the electricity to the motor. Each time a sufficient amount of carbonated water is drawn from the carbonation tank, the cycle will repeat.

Liquid Level Control (Electrode Circuit)

(continued)

When the carbonator tank is full, carbonated water is touching both the low and high electrodes and the liquid level control will not supply power to the carbonator motor.

When carbonated water is drawn out of the tank, it will first fall below the high electrode. This opens the circuit between the “G” and “H” terminals of the liquid level control.

The continued draw of carbonated water from the tank will cause the level of carbonated water to fall below the low electrode. This opens the circuit between the “G” and “L” terminals of the liquid level control. With both circuits open, the liquid level control directs power to the carbonator motor and the pump, turning it “on” and replenishing the supply of carbonated water in the tank.

The carbonated water level will quickly rise to the low electrode and close the circuit between the “G” and “L” terminals of the liquid level control.

Continuing to pump water into the tank, the level will next rise to the high electrode and close the circuit between the “G” and “H” terminals of the liquid level control. This turns the motor

“off” and stops water from being pumped into the tank.

The electrodes work with the liquid level control to maintain the level of carbonated water in the tank. Continuity through the carbonated water from both electrodes (low and high) to the tank

(ground) turns the carbonator motor “off”. No continuity from both electrodes to the tank turns the carbonator motor “on”.

Complete System Overview

Circulating Carbonated Water Supply System

Cold, carbonated water is pushed from the carbonator tank by 90 psig (6.3 bar) of CO

2

, up through the pick up tube and out of the carbonator tank. It is then chilled as it flows through the stainless steel cooling coil located in the 32°F (0°C) water bath. Feeding a stainless steel

circulating pump, the chilled and carbonated water is then forced up to the dispensing station.

Carbonated water from the circulating pump is connected to one of the two carbonated water lines found within the beverage supply conduit. At the opposite end of the beverage conduit, the supply line, along with the remaining return carbonated water line, is connected respectively to the inlet and outlet ends of a turn-around manifold located in the beverage dispensing unit.

Returning carbonated water mixes with newly manufactured carbonated water as it is forced out of the tank to replenish the supply in the circulating loop.

The circulating, carbonated water ensures that the syrups that are also contained within the beverage conduit are properly cooled and that all finished drinks are drawn at 39°F (3.9°C) or less.

Dispensing System

Syrup at the refrigeration unit is pressurized and pushed through cooling coils located in the

32°F (0°C) water bath and then on to the dispensing valves. The push pressure is achieved by one of two methods. One way is by applying direct gas pressure (air or CO

2

) on the surface of syrup stored in stainless steel syrup tanks (figals) which is then connected to the cooling coil. Another way is to use syrup pumps to draw syrup out of bag-in-box containers and then push the syrup through the cooling coils.

Cold syrup flows from the cooling coils and into the beverage conduit where it is then kept cool by circulating carbonated water to the final point of dispensing. Activating a dispensing valve allows syrup and carbonated water to escape through the diffuser/nozzle assembly of the valve. The actual mixing of the beverage occurs as the syrup and carbonated water enter the nozzle. As the beverage falls from the nozzle, it continues to mix until captured in the customer’s cup, where mixing is completed.

To ensure consistent mixing, the dispensing valves are equipped with adjustable flow controls that react to line pressure changes, opening and closing orifices to keep a constant ratio of carbonated water to syrup.

Water Regulator

Function of the water regulator

Regulates the incoming water pressure to 55 psi (3.8 bar) preventing “flooding” of the carbonator tank in locations with high water pressure.

Failure of the water regulator

An unregulated water supply can overcome the 90 psi (6.2 bar) CO

2

pressure in the carbonator tank and prevent the proper absorption of CO

2

into the water resulting in poor carbonation.

Notes:

Water Filter

Function of the water filter

Filters out both solid and suspended impurities found in the water supply. Preventing damage to components, insuring proper absorption of CO

2

into the water and a drink free of “off” taste.

Failure of the water filter

Solids

With use, filter will become restricted to the point of starving water pumps, effecting drink recovery rate.

Suspended

With use, filters will become saturated, effecting drink taste.

Activate Filter by (activate when system is not in use):

1. Put filter on by-pass.

2. Open activation valve (to relieve pressure).

3. Replace cartridge.

4. Slowly take filter off bypass (leaving activation valve open).

5. Activate for proper amount of time.

Notes:

Accumulator Tank Pressures

Multiplex Company, Inc.

Component Parts Workbook

Accumulator tanks have a rubber diaphragm in the middle of the steel tank, air is stored on one side of the diaphragm and water is stored on the other side, a plastic liner protects the steel from rust. Multiplex uses accumulator tanks for several purposes:

Water booster tank

A water booster pump is used to increase the incoming water pressure to 65 psi (4.5 bar) to 85 psi

(6.0 bar). We then store that higher pressure water in an accumulator tank. As a result, the pump isn’t running every time water is needed. The air in the tank gives the water a nice push out of the tank so that the water pressure slowly drops, allowing the pump to cycle on run for a short period of time and then cycle off. The air charge of this tank should be 60 psi (4.1 bar) to 65 psi (4.5 bar).

Filtered water accumulator tank

Filtered water is stored in an accumulator tank to be used when the carbonator pumps demand more water than will flow through your restricted water filters, and then slowly refill the tank when the pumps shut “off”. This enables you to use your filters for a longer period of time. The air charge of this tank should be 15 psi (1.0 bar) to 20 psi (1.4 bar).

The air charge in the tank should be filled or checked with no water pressure to the tank, because once you have water pressure applied to the tank the air will compress and equalize with the water pressure and you will get a false reading.

It is very important to use air and not CO

2

to charge the tank, because CO

2

will eventually bleed through the rubber diaphragm, thus reducing the charge in the tank.

On the bigger WX103 tank, when used as a water booster tank, it is critical to have the 60 psi

(4.1 bar) to 65 psi (4.5 bar) air charge, because if the air pressure drops below 45 psi (3.1 bar), the diaphragm will break.

Primary Regulator

Function of the primary regulator

Regulates the CO

2

tank pressure to maintain a constant 90 psi (not over, not under) for the production of carbonated water.

Failure of the primary regulator

Low pressure or a “sluggish” regulator will cause poor absorption of CO

2

into the water resulting in poor carbonation.

High pressure or a “creeping” regulator will cause increased absorption of CO

2

into the water resulting in over carbonation.

Secondary Regulator (Syrup Regulator)

Function of the secondary regulator

Regulates the CO

2

or air pressure used to push the syrups to the dispensing valves.

Failure of the secondary regulator

Low pressure or a “sluggish” regulator will cause an insufficient supply of syrup during dispensing, resulting in drinks that taste over carbonated (fast dispersing foam).

High pressure or a “creeping” regulator will cause increased supply of syrup during dispensing, resulting in drinks that taste flat and under carbonated (slow lingering foam).

w Letting syrup tanks to empty or a defective leaking syrup disconnect will cause air in the lines and foaming at the dispensing valve

(especially at the slab stores with underground chases).

w To clear activate both valves at once until air clears.

w When jumping syrup tanks, always put the new thank on the front

(syrup feed side) and move the partial tank to the back (gas feed side).

2

pressure and manufacture/replenish the carbonated water supply within the carbonator tank.

Failure of the carbonator pump and motor

A weak or defective carbonator pump or motor (key) will cause poor carbonation and limit the capacity of the unit to manufacture carbonated water.

To determine the approximate cycle time:

1. Right after the carbonator kicks off, draw the carbonated water into a volume cup until the carbonator starts again.

2. Note how many ounces you have and multiply by 0.28 to determine how many seconds your cycle time should be.

Carbonator Pumps

(continued)

All Multiplex equipment requires carbonator pumps with a 250 psi (17.6 bar) relief setting.

w

This relief valve is designed to relieve in emergency situations only (when you have a serious restriction on the outlet of the pump. For example, a freeze up of the cooling coil in the water bath, etc.) w A standard carbonator pump has a 170 psi (12 bar) relief valve setting. Multiplex equipment generates quite a bit of back pressure, thus causing the standard 170 psi (12 bar) pump to relieve excessively. This causes wear to the relief valve, prematurely weakening the pump.

Determining the strength of a carbonator pump

Note: Do not be dispensing drinks during the test.

1. Dispense carbonated water until the carbonator pump cycles on, then stop.

2. Wait for the carbonator to cycle “off”, then turn “off” the electrical switch for the carbonator.

3. Dispense exactly 50 fl oz (2 L) of carbonated water only.

4. Turn “on” the electrical switch for the carbonator and time how many seconds it takes to cycle “off”. This is the actual cycle time.

5. From the chart on the following page, determine the expected cycle time.

For example:

50 ounces x .28, for a 100 GPH pump =

14 seconds

2 liters x 9.52 for a 378.5 LPH pump = 19 seconds

6. If your actual cycle time is much greater than your expected cycle time, your pump has been weakened and the capacity of your equipment has been reduced.

Procedure for properly adjusting the relief valve setting on a pump

1. Remove the large acorn nut on the top side of the pump.

2. Mount a gauge on the outlet flow of the pump

(as shown, to totally block the discharge flow).

3. Turn “on” the pump. While the pump is running, adjust the relief valve screw so that the gauge reads 275 psi (19.3 bar) (250 psi

[17.6 bar] relief setting + 25 psi [1.7 bar] safety factor).

4. Reassemble.

Low Water Pressure Safety Circuit

If water pressure is greater than 4 psi (0.3 bar), the pressure switch will be open and not allow electricity to pass, and the relay will be closed and allow electricity to flow to the motor.

If the water pressure drops below 4 psi (0.3 bar), the pressure switch will close and allow electricity to flow to the relay, heating the relay, causing it to open, stopping the electricity from flowing to the motor.

If the water pressure then goes above 4 psi (0.3 bar), the pressure switch will again open, stopping the electricity from flowing to the relay, the relay will start to cool, after about 3 minutes the relay will close, again sending electricity to the motor.

Liquid Level Control

Function of the liquid level control

Switches “off” and “on” the carbonator pump and motor when the electrodes indicate a full or empty tank. Continuity across L and H to G cause the liquid level control to switch “off” the carbonator pump and motor. Open circuits across L and H to G cause the liquid level control to switch “on’ the carbonator pump and motor.

Failure of the liquid level control

Defective liquid level control will cause the carbonator pump and motor to run continuously or not at all.

Note: For proper voltage meter reading, you must test to ground or you will get a ghost reading.

Notes:

Equipment Installation Instructions for

Multiplex Remote Condenser and Pre-charged

Refrigeration Lines

Pre-installation requirements

Multiplex Remote Condenser Requirements

1. Installation and maintenance are to be performed only by qualified personnel who are familiar with local codes and regulations, and are experienced with this type of equipment.

2. Equipment of this type is intended for installation by qualified refrigeration mechanics.

As a condition of the warranty, the check test and start-up procedure must be performed by qualified personnel. Because of possible shipping damage, both the Condensing Unit and

Refrigeration Unit(s) must be checked for refrigerant leaks.

3. Check to insure that the Remote Condensing

Unit, the Refrigeration Unit, and the Charged

Refrigerant Lines are marked with the same refrigerant.

Multiplex Pre-charged Refrigeration Lines

Requirements

1. Both the Discharge and Liquid Remote Condensing lines should be kept to a minimum distance for maximum performance. All Multiplex systems are capacity rated to 100 ft

(30.5 m) distance between the Compressor and

Condenser. Systems with distances greater than this will experience some efficiency loss in proportion to the distance. This should be a minor capacity loss, less than one drink per minute up to 300 ft (90 m).

2. Any vertical rise greater than 25 ft (7.62 m) must have a manufactured or installed trap

(bend), in at least the Discharge Remote Condenser Refrigeration Line. A trap is necessary for every additional 25 ft (7.62 m) vertical rise.

When excessive vertical rise exists, this trap allows oil to reach the Condenser and return to the Compressor.

Remote Condenser

3. The easiest method to create a trap, is to bend the tubing (smoothly, no kinks) into the trap form (refer to figure 3).

4. This trap(s) should be of minimum height of

3" (7.6 cm) and a width of 6" (15.2 cm) to minimize oil accumulation.

5. It is critical that the Multiplex Remote Condensing line size specifications for the specific model, be maintained. The specifications are normally lines.

Installing the multiplex remote condenser

The Multiplex Remote Condensing Units have either a 230 Volt, 50/60 Hz, 1 PH Fan Motor or a 120 Volt, 50/60 Hz, 1 PH Fan Motor that includes a permanent split capacitor and internal inherent overload protection. Motors are factory wired to an external disconnect switch located on the end of the unit.

Refrigeration unit has an electrical nipple extending out of the back left side with the electrical wires from the refrigeration contactor extending through. The electrician must install an electrical box at this location. Connect the conduit to this box and the Remote Condenser.

The electrical installation should be in accordance with local codes, National Electrical

Code and regulations. Proper fuse protections should be provided for the Fan Motor.

1. Determine a position for installation that will allow access for maintenance and is free from obstruction.

2. Install the four (4) legs to the sides of the condenser using the mounting bolts provided.

3. Secure two (2) treated 4" x 4" to the roof or mounting surface. Mount to the Remote Condenser (refer to figure 1).

4. Install a 3" Pitch Pot in the roof (refer to figure 2). Seal for weather protection.

5. Locate the Pre-charged Refrigeration Lines shipped with the system. These lines should be a correct length for the building design.

Neatly avoiding any kinks, route these lines from the Remote Condenser to the Refrigeration Unit.

Caution: Excess refrigeration line should be coiled and placed in a horizontal (flat) position. When stored in a vertical position, the loops act as an oil trap and will effectively reduce the performance of our equipment as well as increase the risk of compressor failure.

Connecting the pre-charged refrigeration lines

Note: Before connecting the Pre-charged Refrigeration Lines, the Refrigeration Unit must be properly located, leveled, and the water bath filled 1"

(2.5 cm) below the drain pipe.

1. Attach low side Gauge Set to service port on each line set to verify positive pressure within the line set. If there is positive pressure, assume line set is fully charged.

Note: If for any reason the lines are damaged and/ or leaking or lines are no longer charged, refer to

”How To Re-charge the Line Sets”.

2. Always make the connections at the Condenser first, using the end of the Pre-charged Lines with the valve ports.

3. Connect the Condenser side one time quick connects (discharge and liquid) up to Condenser.

Refer to the section titled “Aeroquip

Connection” in these instructions.

4. Check that the sight glass clears during pull down to verify the Line Set charge.

5. If the sight glass does not clear, attach the gauges. Adjust the charge if necessary.

How to re-charge the line sets

Note: This procedure to be used only with damaged or evacuated Line Sets or with unknown refrigerant type.

1. Repair any damages to the Line Sets before proceeding.

2. With the Remote Condenser lines properly hooked and sealed to the Condenser, evacuate to 30 in mercury (76.2 cm mercury) for 1 hour, using one or both Schrader ports on the service

Line Set.

3. Charge the Condenser and Line Set accordingly.

Add 0.72 oz/ft (0.067 kg/m) of Remote Line Set

(one way run distance) plus 6 oz (170 g) of refrigerant for any size Condenser.

Example:

50 ft of Line Set

50 x 0.72 = 36 oz

36 oz + 6.0 oz = 42.0 oz (Total)

4. Connect Line Sets to the proper discharge and liquid mating connectors on the Refrigeration

Unit using one (1) time quick connects. Refer to the section titled “Aeroquip Connection” in these instructions.

5. Be sure to observe proper refrigeration technique when running the Line Set.

Proper Refrigeration Technique for Running the Line Set a. The discharge line should loop down at the Compressor end to trap liquid from returning (refer to figure 3).

b. The Discharge Line should loop above discharge connector at the Condenser to resist liquid returning to the Compressor.

Any excess line should be coiled horizontally with line from the Compressor at top and line to the Condenser at bottom to keep from trapping oil and returning liquid.

c. Discharge line should be trapped (P Trap) every 20-25 ft (6.1-7.6 m) of vertical rise, to allow oil to “stair-step” up to the Condenser and eventually return to the Compressor.

Note: When the connections are made, the seal in the couplings are broken and if removed for any reason, the refrigerant charge will be depleted.

Caution: Relays and terminal block are energized from each remote unit. Turn “off” switches on each unit before, opening quick disconnect switch on condensing unit. On the completion of the wiring of the Remote Condenser make sure the electrician placed the switch lever in the “on” position. This switch must be “on” before turning

“on” the refrigeration toggle switch on the unit.

Also, the water bath must be filled with water.

Aeroquip Connection

1. Lubricate male half diaphragm and synthetic rubber seal with refrigerant oil.

2. Thread male coupling to its proper female half by hand to insure proper mating of threads.

3. Use proper wrenches (on coupling body hex and its union nut) and tighten union nut until coupling bodies “bottom”.

Note: You must use body wrench to keep body from turning while tightening nut with the second wrench. If body turns excessively, piercing seal will be damaged.

4. Use proper wrenches to tighten an additional

1 /4 turn (90°). This final 1 /

4

turn is necessary to insure the formation of a leak proof joint.

Alternately use a torque wrench to tighten 1

Head Pressure Control

(used on Remote Condensing units only)

Function of the head pressure control

As the evaporator discharge pressure drops when the outside temperature drops, gas will by-pass the roof condenser and be metered into the receiver maintaining an adequate head pressure.

Failure of the head pressure control

A valve incapable of by-pass will effect the refrigeration unit when the outside temperature drops below 60°F with little or no ice production.

A valve stuck in by-pass will cause high head pressure and effect the ice production capabilities of the unit.

Multiplex Programmable

Portion Control Timers

What’s New at

Multiplex

We have received some requests to publish descriptions explaining the differences between the various models of Multiplex programmable portion control timers. The following is not intended to be a step by step procedure, but is only a general overview of the unique features of each timer.

The Model 66 was the first programmable portion control timer.

It requires a 9 volt battery to retain its memory during power outages. Its 3-Size timer utilizes a separate rocker switch for calibration. To set the drink sizes: w Turn the calibration rocker switch to the “on” position.

w Push the respective size pad for each keypad position at each valve.

w Repeat this process for each valve.

w Once complete, turn off the rocker switch to store the programmed sizes into memory.

The Model 64 is similar to the Model 66, except that the 9 volt battery is no longer required, since memory is stored on a memory chip. Its 4-Size timer still requires the rocker switch for calibration.

There are major improvements with the Model 64A Revision B.

The 4-Size timer uses a calibration button, integrated into the keypad, rather than a rocker switch. A 4 second pour feature permits easy flow rate adjustments and volume settings for all valves simultaneously from valve number 1, in an emergency. To adjust the flow rate: w Push the CAL pad three (3) times in less than three (3) seconds to enter calibrate mode. Calibration light will go on.

w Push the STOP/FILL pad once on any valve to achieve a 4 second pour for that valve.

w Once the valve water flow adjustments are complete, push the

CAL pad once to exit calibrate mode. Calibration light will go out.

w To adjust the Brix (water to syrup ration) for each valve, push the CAL pad three (3) times again.

w Push the respective size for each valve until you achieve the desired drink level in your cup.

w Exiting calibrate mode (pushing CAL pad once) will lock the programmed sizes to memory.

The Model 64A Revision C is similar to the Model 64A Revision B except that the volume settings can be completely accomplished from any valve. To adjust all valves to the same times: w Push CAL pad three (3) times and push the STOP/FILL pad on any valve (except valve number 1) two (2) times.

w Program each size for that valve.

w Exit calibration mode by pushing CAL pad once. This will lock the programmed sizes for all valves into memory.

Note: It is extremely important that all valves be adjusted to exactly the same water flow rate. If any valve is adjusted to a different flow rate (no matter how slight), it will have to be readjusted separately.

You may now order new push-button replacement labels for the 4-Size timers that are used on the Model CPss150-

MD200 and Model 116 tower.

To replace, peal back worn push-button label carefully with a knife edge as shown above.

Peel the covering from the back of label. Attach new label and apply light pressure to adhere the new label to the timer.

Please see below for correct label to order for your timers.

Instructions for Proper Dispensing Valve

Calibration (Flow, Ratio, and Volume) using the 4-Size Portion Control

Flow

(to set the water flow rate only)

Check that the Primary CO

2

tank high pressure regulator or bulk CO

2

regulator is adjusted properly. The Medium pressure regulator for sugar-based syrup must be adjusted to 60 psi (4 bar). The Low pressure regulator for sugar-free syrup must be adjusted to 14-16 psi

(0.9-1.1 bar).

1. Turn “off” the syrup at the dispensing valve by turning the syrup shut-off (located on the valve mounting block). If there is no syrup shut-off, use a syrup separator.

2. Check the water shut-off (if applicable). It should be in the full open position.

Note: The syrup and water shut-off (if equipped) are not to be used as an alternate for flow controls. They are to be used only for shutting on or off the syrup and/or the water supply.

3. Place a volume cup with 10 oz. (295.7 mL) measurement line, under valve to be adjusted.

If using syrup separator, place volume cup under water side of separator only.

4. Use 4-Size portion control timer to obtain an accurate 4 second pour as follows: a. Press CAL pad three (3) times in less than

3 seconds to enter calibrate mode. Calibrate lamp will light. (Omit this step if already in calibrate mode).

b. Press STOP-FILL pad of valve to adjusted once to cause 4 second pour into volume cup.

Note: Fast-fill valves will dispense 10 oz in 4 seconds and standard-fill valves will dispense 5 oz in

4 seconds. Diet and other products with high foaming tendencies would be adjusted to 7.6 oz and

3.8 oz respectively.

5. To adjust the water flow rate (if necessary), turn the adjusting screw clockwise to increase and counterclockwise to decrease the flow of water.

6. Repeat 4 second dispense (STOP-FILL pad) and water flow adjustment, until volume is correct.

7. Open syrup shut-off or remove syrup separator (if applicable).

8. Repeat this procedure (steps 1 through 7 above) for each valve.

9. Press CAL button once to exit calibrate mode.

Calibrate lamp will go “off”.

Ratio

(water to syrup mixture)

1. Remove valve nozzle by turning the nozzle and pulling down.

2. Place syrup separator on valve to be adjusted.

Actuate the valve manually (pad, lever) until both syrup and water flow out of the syrup/ water separator.

3. Position the proper ratio cup under the syrup separator. Manually actuate the valve pad or

3 lever valve (pad, lever). Dispense until at least

/

4

of the ratio cup is filled. Both products should fill to the same level.

4. To adjust the syrup flow (if levels are not equal), turn the syrup flow control adjusting screw clockwise to increase and counter-

clockwise to decrease the flow of syrup.

Note: Do not adjust the water flow during this procedure.

5. After syrup is adjusted, remove the syrup separator and replace the valve nozzle.

6. Repeat this procedure (steps 1 through 5 above) for the remaining valves.

Volume

(setting drink portion sizes)

1. To enter portion control calibrate mode, press

CAL pad three (3) times in less than 3 seconds. Calibrate lamp will light.

2. Use volume cup with finished drink marking lines, or use correct size sample cup with desired volume of ice.

3. Press and hold respective SIZE pad until product gets close to proper finished drink mark, or until close to top of sample cup.

4. Release SIZE pad before reaching final mark or before foam exceeds final mark. Press SIZE pad again momentarily, as many times as is necessary (letting foam settle), to get to the correct finished drink mark.

5. Repeat steps 2 through 4 above for all sizes and all stations (products) needing calibration.

Be sure to use the correct volume cup finished drink marking line, or correct sample cup size and ice amount, for each size pad.

Note: If you fill above the final mark or need to

"start over" for any reason, you must exit the calibrate mode and then re-enter the calibrate mode to resume.

6. Exit calibrate mode by pressing CAL pad once.

Calibrate light will go out. All changes will be permanently saved.

MOV’s field testing

Metal Oxide Varistors installed on the water and carbonated water buttons, on McDonald’s style dispensing towers, are designed to completely absorb electrical spikes keeping them out of the microprocessor circuit eliminating complaints of: w Not holding calibration w Valves flowing by themselves w Two valves coming on at the same time, etc.

Multiplex has designed a field test procedure that will expose a faulty MOV. This procedure will also work on the older style capacitors.

The field test procedure:

Depress separately both the water and soda water button rapidly 5-6 times. While doing this, watch all other valves. If you notice any dripping or any other valve trying to energize, the MOV’s need to be replaced.

Note: Factory installed MOV’s have heat shrink tubes on each terminal leg. Always check to make sure that heat shrink has not slipped down and is insulating the MOV leg inside the terminal connector.

Complete System Overview

New Model MPC84A Portion Control Board

A new portion control board, the Model MPC84A, has been developed to improve the performance and maintain the functions and feature of the previous Model MPC64A. In addition, this

Porction Control board has passed the very demanding EMC (radio frequency emissions and interference) testing for European CE approval, at the UL labs. The Model MPC64A has been phased out as of June 1996. Only the Model MPC84A will be used on new production and for service.

The new bard is the same size, has the same mounting locations, and uses the same connectors as the previous board. This article is to explain the features (which can be used to your advantage) and minor differences.

The major difference is the same size board. The Model MPC84A can control up to eight stations

(dispensing valves) with up to four sizes per station. The Model MPC64A could control up to six stations.

The illustration in Figure 1 depicts the connectors on the Model MPC64A. The illustration in

Figure 2 depicts the connectors on the Model MPC84A.

The power connectors J15 and J20 (24 VAC) are the same. The keyboard connectors, J16 for touchpad and J17 for calibration touchpad, are the same.

The Model MPC84A adds one more two pin keyboard connector, the J1. For an eight station tower, this connector, along with a separate two wire cable to the proper keyboard, provides the two extra stations.

The five pin valve connectors, the J7 to J12 on the Model MPC64A, are changed to a two pin connectors, the J7 to the J14 on the MPC84A. These valve connectors are not polarized (does not matter how you connect the two pins) except when the valve has a “water” or a “soda” harness.

The calibrating functions of the new portion control board are the same as the old board.

Note: Use a Calibration cup (or an appropriate size cup with the right amount of ice).

1. Press the respective size button for that cup

(small, medium, large, etc.) at that station.

2. Fill the cup with product to the correct level.

Note: This same size button may be started and stopped as many times as desired to acquire the correct level while letting the drink settle. All times for same station and size are additive in the program session.

3. Repeat volume sizing procedure for all sizes and stations.

Flow Rate Calibration

Press any STOP-FILL button one (1) time. That respective valve will flow for exactly 4 seconds allowing for checking or adjusting the valve flow rate.

One Station Sets All

After entering the Calibrate Mode, press any

STOP-FILL button two (2) times in less than 1 second. The CAL light will flash constantly. Now all volumes on that station programmed in this session will copy to all other stations.

Exiting the Program Mode

To exit the Program Mode, press the CAL button one (1) time turning “off” the CAL light. All volume changes made during this session will permanently be stored.

Top-off program mode

Entering the Top-off Program Mode

To enter the Top-off Program Mode, press the

CAL button five (5) times in less than 3 seconds.

The CAL light will flash each time it is pressed and flash five (5) times after 3 seconds. The light will remain “on”.

Enabling and/or Disabling the individual station Top-off

Enabling the individual station Top-off allows every size dispensed on this station to pour all the volume programmed in two (2) pours with a 3 second delay between pours. Disabling the individual station Top-off allows every size dispensed on this station to pour all the volume programmed.

1. Press the STOP-FILL button on the station desired to change the top-off mode.

2. The CAL light will immediately flash five (5) times to indicate the top-off mode has been toggled. If the respective station was disabled for top-off, then it will toggle to enable for top-off. If the respective station was enabled for top-off, then it will toggle to disable for top-off.

Exiting the Top-off Program Mode

To exit the Top-off Program Mode, press the

CAL button one (1) time turning “off” the CAL light. All station top-off mode changes made during this session will permanently be stored.

Test mode

1. With the power “off”, press the CAL button and turn power “on” simultaneously.

2. Release the CAL button. The Portion Control board will sequence each station for 4 seconds starting with the leftmost.

3. Check that each LED on the Portion Control board comes “on” sequentially and all valve solenoids fire.

Note: If the LED light does not come “on” for any station(s), the Portion Control board is bad. If the

LED light comes “on” but the valve does not fire, check wiring and valve solenoids.

Sanitation mode

1. With the power “off”, press the CAL button and turn the power “on” simultaneously.

2. Release the CAL button. Each station will come

“on” for 4 seconds sequentially. This allows automatic pouring of the sanitation fluid from each station constantly until each line drains.

Note: If the drain can support more than one (1) valve pouring at a time, press the STOP-FILL button on the station number for the number of valves flowing simultaneously.

Example: At station number 3, press the STOP-

FILL button. Three (3) valves will flow simultaneously.

Complete System Overview

McDonald’s Portion Control Timer

A common problem associated with the McDonald’s style portion control timer is when one size becomes non-adjustable. This may not be more than the trimming potentiometers being adjusted out of the usable range. To bring them back into range, all that must be done is to turn the screw counterclockwise 20 complete turns, and then clockwise:

Adjusting portion control for size of drinks dispensed

1. Simultaneously press and hold “S” (SMALL) and “X” (EXTRA LARGE) push button switches on Coded Autoset Portion Control Module until LED light in center of module starts blinking, then release switches. Blinking LED indicates set mode is active.

2. Put desired amount of ice in cup, place cup under valve and push selected size button

(small, medium, large, or extra large). Hold button in until cup fills to desired portion then release button. Wait for foam to settle then actuate button again to top off. Repeat the above procedure for remaining sizes.

3. After programming all drink sizes, press and release “CANCEL/POUR” switch to return the

Coded Autoset Portion Control to the operational mode. Blinking LED light will go out.

Note: If top-off is not desired or required, the following steps must be followed: a. Follow step 1 above.

b. Put desired amount of ice in cup, place cup under valve and push selected size button (small, medium, large, or extra large). Hold button in until cup fills to desired portion then release button.

Note: After actuating the last selected size button, momentarily actuate one of the other size buttons. This will signal the microprocessor that all selected sizes are completed. Failure to do this will signal an incomplete response back to

the microprocessor and the last selected size will revert back to its previous program.

If, at a future date, it is decided to change portion size of the drinks or omit or add the top off feature, the individual sizes can be adjusted by the above procedure. It is not necessary to reprogram every size.

Small

Fountain Troubleshooting Guide

Foreword

This Troubleshooting Guide has been developed to assist you in determining what the Probable Cause for any particular Problem you may experience with your Multiplex Beverage System could be. It then advises of the proper Corrective Action to be taken to remedy that Problem.

Because of the ever present danger from electrical shock, and the existence of high pressure water and gas on the system, it is strongly recommended that only qualified service personnel perform actual repairs.

To use this guide you should first recognize the Problem. Once this has been accomplished, you should refer to the Problem Cross Reference Guide, which will direct you to the troubleshooting section or sections which may be responsible for that particular Problem.

Under each of the sections, Section 1: CO

2

Gas System, Section 2: Carbonated Water System,

Section 3: Circulating System, Section 4: Compressed Air System, Section 5: Dispensing valve and tower, Section 6: Electrical System, Section 7: Refrigeration System, Section 8: Syrup System,

Section 9: Water Booster System, and Section 10: Water Filter System, you’ll first find the Problem listed in bold type starting on the left margin. It will be followed by three headings also in bold type and each with its own column. The first is a Qualifier which is designed to quickly qualify or eliminate the Probable Causes listed to the right and below the qualifying statement. Example: Under Section 7:

Refrigeration System, you’ll find three Qualifiers for the same problem, “Warm drinks”. Carbonated

Water Temperature over 40°F (5°C)”. Each asking you to determine the status of the Refrigeration

Compressor and Ice Bank before proceeding to the second column Probable Causes. Not all problems have Qualifiers, but for those that do, first examine each one listed below the Problem before continuing through Probable Causes. The third heading, Corrective Action found on the right margin, will direct you in determining if the Probable Cause is actually responsible for the problem and what should be done to remedy the problem.

On occasion, you’ll find “Note” and “Caution” statements which have been included to make special references to items which frequently are misunderstood or ignored.

This guide is intended to assist you in locating the cause of a problem. It is not, however, to be considered a service and repair manual in that Multiplex models vary in design.

It has been written to encompass all model Refrigeration Units. Some differences from model to model will become obvious and it will be required of the reader to apply this guide to each unit. Of main concern, is on Dual Carbonating and Circulating Systems you must consider there are two separate Carbonating and Circulating Systems.
