INSULATING CONNECTIONS

1. Make sure all exposed carbonated water and syrup lines are well insulated on towers to conduit, conduit junctions, refrigeration unit to conduits, and drivethrough junction.

2. To insulate the above, use the leftover conduit sections and tape.

3. Cut the conduit sections to fit snugly over the exposed lines and fittings. A little extra time spent doing a thorough job initially will eliminate a call back in several days to make corrections.

NOTE: Do not inject foam material directly on the connections where the tubing connects to the barb fittings or directly on poly tubing.

Aerosol Foam

Chase

NOTE: You must use a wrench on the body to keep the body from turning while tightening the nut with the second wrench. If the body turns excessively, the 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 ensure the formation of a leak proof joint. Alternately, use a torque wrench to tighten the 1/2" coupling to 40 ft-lbs and 3/8" fitting to 11 ft-lbs.

5. Leak check all your connections. If you detect any leaks, repair and recheck.

Condenser and Pre-charged Lines Installation

Before proceeding with installation, verify that all requirements for roof mounted remote condenser units (if applicable) have been satisfied. If unit has a remote condenser, refer to the instructions on installing the remote condenser supplied with the condensing unit and refer to the section on installation of remote refrigeration line sets.

Caution

If you are installing a remote unit, there is a refrigeration king valve located behind the compressor. This valve must be back-seated prior to starting the compressor. Failure to do so will short cycle and may damage the compressor.

4. The can of foam is to be used to fill the openings between the conduit insulation and the inside diameter of the floor chases. The purpose is to provide an air tight seal at the floor level to prevent foreign matter from entering the chases. Please read the foam manufacturer’s instructions carefully. We recommend using the adapter with the right angle extension.

5. Insert the adapter into the openings approximately 1" to 2" (2.5 to 5.1 cm) while depressing the adapter.

6. Move the extension around throughout the area where the foam is to be placed. Do not over fill, allow room for expansion. If the chase opening is too deep, insert a section of the leftover conduit insulation in the opening prior to using the foam insulation.

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 ensure proper mating of threads.

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

REMOTE CONDENSER REQUIREMENTS

APPROVED CONDENSERS

Multiplex Condenser - TS0895-271

MAC Multi-Pass Condensers

1. Installation and maintenance are to be performed only by qualified refrigeration personnel. These technicians must have EPA certification (USA), must be familiar with local codes and regulations, and must be experienced with this type of remote refrigeration equipment.

2. As a condition of the warranty, the check, test and start-up procedure must be performed by qualified personnel. Because of possible shipping damage, check both the condensing unit and refrigeration unit(s) for refrigerant leaks.

3. If the refrigeration unit is located on a roll out platform, you must coil up to one round between the back of the stand and the wall. This allows pull out of the refrigeration unit for servicing.

4. If the refrigeration unit is located in a stationary location, you must remove excess refrigeration tubing as described below.

Part Number 020002365 08/25/2015 27

Installation Section 2

PRECHARGED REFRIGERATION LINE REQUIREMENTS

Important

If you have a MAC Multi-Pass condenser, please add three (3) pounds additional charge.

1. Both the discharge and liquid remote condensing lines must be kept to a minimum distance for maximum performance. All Multiplex systems are capacity rated to 100 ft (30.5 m) tubing distance between the compressor and condenser. If you have another brand condenser, please add additional charge for the condenser (example: up to three (3) pounds for a MAC condenser).

2. Any vertical rise 25 ft (7.6 m) or greater must have a manufactured or installed trap (bend), in the discharge refrigeration line from the compressor to the remote condenser. A trap is necessary for every additional 25 ft (7.6 m) vertical rise. When excessive vertical rise exists, this trap allows oil to reach the condenser and return to the compressor.

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

Discharge Line

Condenser Trap

1. Determine a position for installation that will allow access for maintenance and is free from obstruction. Verify hot air discharge from other condensers does not interfere with the inlet of this condenser.

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

3. The General Contractor or Owner must secure two treated lumber 4" x 4" x 36" (or longer). You may then mount the remote condenser to the treated lumber.

4. The General Contractor or Owner must install a 3" pitch pot in the roof. Then seal for weather protection.

4. The trap(s) must be of minimum height of 3" (7.6 cm) and a width of 6" (15.2 cm) to minimize oil accumulation. The traps can also be bent out of the refrigeration tubing. Carefully bend the tubing down 12" (30.5 cm), and then sweep the tubing back up.

5. It is critical that the Multiplex remote condensing line size specifications for the specific model be maintained. The specifications are 1/2" discharge and 3/8" liquid lines.

Installing the Multiplex Remote Condenser

The Multiplex remote condensing units have a 208-230 Volt, 50/60 HZ, 1 PH fan motor that includes a permanent split capacitor and internal overload protection. The electrical wires from the refrigeration unit wire to the condenser. The electrical installation must be in accordance with local codes, National Electrical Code and regulations.

5. Locate the pre-charged refrigeration lines shipped with the system. These lines must be a correct length for the building design. Avoiding any kinks, neatly route these lines from the remote condenser to the refrigeration unit. Excess refrigeration tubing must be handled in one of two ways. When coiling the excess tubing, make sure the inlet to the coil is at the top of the coil and the exit is the bottom of the coil. There can be no more than one turn to the coil. If you have more tubing, you must cut out the excess before connecting the ends. When cutting the tubing, you must first evacuate the refrigerant (line sets have a positive refrigerant holding charge of two to three ounces). After shortening and welding the tubing together again, you must evacuate the tubing to 250 microns. Then recharge the tubing with 4 ounces of appropriate refrigerant.

Caution

Excess refrigeration tubing must be properly cared for before being connected to either the remote condenser or the refrigeration unit.

28 Part Number 020002365 08/25/2015

Section 2 Installation

CONNECTING THE PRECHARGED REFRIGERATION LINES

Important

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

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 installed drain pipe.

1. Attach low side gauge set to service port on each line set to verify positive pressure within the line set.

NOTE: If for any reason the lines are damaged and/or leaking, the lines are no longer charged or if the line set is too long for the application, refer to “Installing the Multiplex Remote Condenser”.

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 with the quick connectors (discharge and liquid) up to condenser. Refer to the section titled “Aeroquip Connection” in these instructions.

4. Connect the refrigeration unit side with the quick connects (discharge and liquid). Make sure to provide a discharge trap at back of refrigeration unit, or bend discharge line down 12" and then up smoothly (no kinks) to provide a trap.

5. If a low refrigerant charge is detected, recover and recharge the system adding the unit name plate charge.

6. Repair any damages to the line sets before proceeding.

Testing

TESTING CO2 CIRCUIT FOR LEAKS

It is advisable to test the system for leaks before turning ON the water supply to the carbonator and connecting the syrup tanks. If a leak does exist, it will be easier and faster to make any correction.

1. Turn ON the CO2 supply and adjust the primary regulator to 90 psi (6.2 bar)(620528.156099999906 Pascals).

2. Position the CO2 tank changeover valve handle (if applicable) toward this regulator.

3. Move the air/CO2 changeover valve to the CO2 position (if applicable).

4. Allow the CO2 gas to enter the system.

5. Wait for 2 or 3 minutes before turning OFF the CO2 tank valve. This will allow the lines to expand under pressure.

6. Turn OFF the CO2 tank valve. Observe the pressure on the high pressure gauge (not the 90 psi [6.2 bar] [620528.156099999906 Pascals] operating gauge). The needle may drop approximately 1 psi (.09 bar) (6894.75729 Pascals), but must remain constant and not lose pressure. Wait for several minutes.

If pressure continues to fall, this indicates there is a leak in the system which must be corrected.

The greater the leak, the faster the pressure will drop. The smaller the leak, the slower the gauge will drop.

It may be necessary to use a soap solution at all connections to locate a very small leak.

CO2 gas must be present on all valves of the tower(s)

NOTE: All soap solution must be rinsed thoroughly from tubing upon completion of testing.

TESTING SYRUP CIRCUIT 5 GALLON TANKS ONLY

Before connecting the syrup tanks to the system, the syrup circuits must be tested for leaks with CO2 gas.

1. Connect an empty syrup tank to pre-mix syrup circuits.

2. Connect one of the CO2 gas quick disconnects to this tank. Allow the tank to fill with CO2 gas.

3. Observe the pressure of the primary CO2 tank regulator (not the 90 psi [6.2 bar][620528.156099999906 Pascals]).

4. Allow the CO2 tank pressure to remain ON for a few seconds. This will allow the lines to expand to operating conditions.

5. Turn OFF the CO2 tank cylinder.

6. Check all connections from the syrup tank through the connections in the water bath area to all fittings at rear of tower.

7. Check syrup circuitry on the tower by activating the valve.

8. Follow the same procedure for the diet pre-mix beverage circuit.

If no leaks are found in the syrup circuits and the carbonated water circuit, the system is ready to be insulated and placed in operation.

Operation Section 3

How the Multiplex Works

Multiplex Model 42 & 44

• 1 HP refrigeration unit

• Post-Mix carbonated beverages and chilled carbonated water: 21 gal (79 L) of syrup or carbonated water/day or 980 drinks/day (7,500 gal/yr)

• 250 ft (80 m) maximum conduit length

Super-Chil Model SC1000

• 1 HP refrigeration unit

• Chilled water: 29 gal (110 L) in 2 hrs (peak); 15 gal (57 L) in 2 hrs (sustained 24 hrs)

• 250 ft (80 m) maximum conduit length

These refrigeration units are remote refrigeration units that derive their peak capacity from the reserve ice bank. These systems are controlled to cycle ON and OFF by the operation of the ice control. The sensing probe that controls the ice bank is located on an adjustable bracket in the water bath.

Multiplex Model 50

• 2.2 HP refrigeration unit

• Post-Mix carbonated beverages and chilled carbonated water: 42 gal (159 L) of syrup or carbonated water/day or 2,000 drinks/day (15,000 gal/yr)

• 350 ft (107 m) maximum conduit length

Super-Chil Model SC2000

• 2.2 HP refrigeration unit

• Chilled water: 55 gal (208 L) in 2 hrs (peak); 30 gal (114 L) in 2 hrs (sustained 24 hrs)

• 350 ft (107 m) maximum conduit length

These refrigeration units are remote refrigeration units that derive their peak capacity from the reserve ice bank produced by the operation of the compressor. These systems are controlled to cycle ON and OFF by the operation of the ice bank control. The sensing probe that controls the ice bank is located on an adjustable bracket in the water bath.

Start-Up

PLACING EQUIPMENT IN OPERATION

Before placing equipment in operation, verify that all requirements for roof mounted Remote Condenser units (if applicable) have been satisfied. Refer to the instructions on installing the Remote Condenser. Verify proper supply power to unit.

1. Fill the refrigeration unit water bath tank with water to within 1/2" (13 mm) of the top of the overflow tube.

2. Open the manual water shut-off valve to the water cooled condenser (if applicable). Refer to page 3-3 for control programming sequence.

3. Press “Comp/Agit” to begin building an ice bank.

4. Ice will begin to form on the evaporator coils in approximately 2 hours.

5. The refrigeration unit will build an ice bank in approximately 4 to 6 hours.

6. If optional CO2/Water Control Panel has been installed on the refrigeration unit, refer to the installation instructions for operation and testing the circuits for leaks.

7. The carbonation circuits “A” and “B,” as well as the syrup circuits must be checked for leaks and possible cross circuits before turning ON the water supply to carbonator pumps.

8. Turn on main water supply. Set incoming regulator to 55 psi on the CO2/Water control panel. Once water is supplied to the unit, air needs to be purged from the carbonator tank. Do so by lifting press relief valve tab until water comes out of relief valve.

9. Set bag-in-box syrup tank push pressure CO2 regulator to 60 psi.

PLACING THE SYRUP SYSTEM IN OPERATION

1. Open the CO2 gas supply valve at CO2 tanks or bulk tank. Adjust the CO2 pressure to 90 psi (6.2 bar).

2. Open relief valve on top of the carbonator tank for 4 seconds to bleed off air in tank.

3. Verify the water supply to unit is on.

4. Press the switch labeled “Carb A” (and “Carb B” if applicable). Allow carbonator to run and cycle OFF.

5. Press the switch labeled “CIRC A” (and “CIRC B” if applicable).

6. Activate all vales until a smooth, continuous flow or carbonated water and non-carbonated water appear at the valves.

7. Allow at least 1 hour before proceeding to calibration instructions. You may complete the sanitizing instructions during this period.

Section 3 Operation

Sequence of Operation

ELECTRONIC CONTROL

Prerequisites

• Potable water must be connected to the carbonator pump circuit.

• The ice bank water bath water must cover the evaporator. The compressor will not start unless the ice bank control probes are immersed in water.

• CO2 must be supplied.

Initial Power-up

The control has a 30-second delay when power is connected, or disconnected and reconnected. The display will show Pd30 - power delay and 30 seconds left in the countdown cycle.

Normal Operation

NOTE: This sequence of operation includes systems with up to two recirculation/carbonation circuits. Your model may not employ a second circuit or second carbonation pump.

Pressing the COMP/AGIT button will start the water bath agitator immediately and initiate the 180 second compressor delay. The display will show Cd99 (compressor delay & 99 seconds) and will start to count down from 99 seconds after the first 81 seconds have elapsed. After 180 seconds the compressor and condenser fan motor energize and the COMP/AGIT LED flashes. Pressing the CARB A and CARB B buttons will power the carbonator tank liquid level control. The corresponding LED flashes to indicate the pump is running. Pressing the CIRC A & CIRC B buttons will immediately energize the circulating pumps and energize the LED constantly. The display will show the circulating temperature and show the A circuit. When two circuits are used, the readout will alternate between A and B circuits every 5 seconds.

The compressor and condenser fan will continue to run until ice contacts the ice bank control probe closest to the evaporator. When ice contacts the probe, the COMP/AGIT LED lights constantly and the compressor and condenser fan motor de-energize.

As the ice bank melts, the ice bank control probe will lose contact with the ice; the LED will flash and the compressor and condenser fan motor will restart. This cycle will repeat as required depending on load.

Power Interruption

During a power interruption the control will resume from the point of interruption when power is reapplied and the time delay expires. Any switches/components that were energized when power was interrupted will be energized when power is reapplied.

Error Codes

E1 = Low Water Supply Pressure

E2 = Low CO2 Pressure

E3 = Low Water Level - Water Bath

E4 = High Water Bath Temperature

BEVERAGE SYSTEM CLEANING

Warning

Flush sanitizing solution from syrup system.

Residual sanitizing solution left in system could create a health hazard.

Warning

When using cleaning fluids or chemicals, rubber gloves and eye protection must be worn.

Sanitize the beverage system at initial start-up as well as regularly scheduled cleaning. The drain pan must be in place under soda valves, to carry away detergent and sanitizing agents that will be flushed through valves.

BAGINBOX SYSTEM SANITATION

The procedure below is for the sanitation of one syrup circuit at a time. Repeat to sanitize additional circuits.

You will need the following items to clean and sanitize the Bag-in-Box (BIB) beverage system:

• Three (3) clean buckets

• Plastic brush or soft cloth

• Mild detergent

• Unscented bleach (5% Na CL O) or Commercial sanitizer

• Bag-In-Box bag connector

1. Prepare the following in the buckets:

• Bucket 1 — warm, not too hot, tap water for rinsing.

• Bucket 2 — mild detergent and warm, not too hot, water.

• Bucket 3 — mix a solution of unscented bleach (5% Na CL O) or commercial sanitizer and warm, not too hot, water. Mixture should supply 100 PPM available chlorine (1/4 oz. bleach to 1 gallon water).

2. Disconnect the “syrup-line side” of the BIB connector.

Bag side

connector

3. Rinse connector with warm tap water.

4. Connect syrup connector to BIB connector and immerse both into Bucket 1. A “bag-side” connector can be created by cutting the connector from an empty disposable syrup bag.

5. Draw rinse water through system until clean water is dispensed. Most beverage valves allow the syrup side to be manually activated by depressing the syrup pallet.

6. Connect Bucket 2 to system.

7. Draw detergent solution through system until solution is dispensed.

8. Repeat steps 2-7 until all syrup circuits contain detergent solution.

9. Allow detergent solution to remain in the system for 5 minutes.

10. Connect Bucket 3 to system.

11. Draw sanitizing solution through system until solution is dispensed.

12. Repeat step 11 until all syrup circuits contain sanitizer solution.

13. Allow sanitizer solution to remain in system for 15 minutes.

14. Remove nozzles and diffusers from beverage valves.

15. Scrub nozzles, diffusers and all removable valve parts (except electrical parts) with a plastic brush or a soft cloth and the detergent solution.

16. Soak nozzles, diffusers and removable valve parts (except electrical parts) in sanitizer for 15 minutes.

17. Replace nozzles, diffusers and valve parts.

18. Connect Bucket 1 to system.

19. Draw rinse water through system until no presence of sanitizer is detected.

20. Attach syrup connectors to BIBs.

21. Draw syrup through the lines to rinse the system. Discard drinks until at least two cups of satisfactory tasting beverage are dispensed through the valve.

FIGAL BEVERAGE SYSTEM

1. Prepare the following in three clean Figal tanks:

• Rinse tank - fill with warm tap water.

• Detergent tank - mix approved beverage system

cleaner with warm water as directed.

• Sanitizing tank - mix a solution of unscented

bleach (5% Na CL O) or commercial sanitizer and warm to hot water. Mixture should supply 100 PPM available chlorine (1/4 oz. bleach to 1 gallon water).

2. Disconnect all product and water lines from product tanks and remove carbonator.

3. Locate the Figal syrup tank for the circuit to be sanitized. Remove both quick disconnects from the Figal syrup tank. Rinse quick disconnects in tap water.

4. Connect rinse tank to the syrup line. Draw clean rinse water through the valve until syrup is flushed from the system.

5. Connect detergent tank to the syrup line and draw detergent through the valve for two minutes. Then, allow remaining detergent to stay in the system for five minutes.

6. Connect rinse tank to the syrup line. Draw clean rinse water through the valve until detergent is flushed from the system.

7. Remove valve nozzle and diffuser as shown in Daily Cleaning instructions. Using a plastic brush or a soft cloth and warm water, scrub the nozzle, diffuser, bottom of the dispensing valve and cup lever, if applicable.

8. Place removable valve parts (EXCEPT solenoids) in sanitizing solution for 15 minutes.

9. Replace valve diffuser and nozzle on the beverage valve.

10. Connect sanitizer tank to the syrup line and draw sanitizer through the valve for two minutes. Allow sanitizer to remain in the system for a minimum of 15 minutes.

11. Reconnect syrup and carbonated water lines.

12. Draw syrup through the lines to rinse the system. Discard drinks until at least two cups of satisfactory tasting beverage are dispensed through the valve.
