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 CO may build up in an area, venting of the BIB pumps and/or CO2 monitors must be utilized.

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.
Important
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), are familiar with local codes and regulations, and are experienced with this type of remote refrigeration equipment.
2. As a condition of the warranty, the check, test and start­up 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.
2-16
Part Number 020001552 5/11
Section 2 Installation

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 (7.62 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 (7.62 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", 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 vacuum the tubing to 250 microns. Then recharge the tubing with the appropriate refrigerant at 4 ounces per length of tubing.
Caution
!
Excess refrigeration tubing must be properly cared for before being connected to either the remote condenser or the refrigeration unit.
Part Number 020001552 5/11 2-17
Installation Section 2

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 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 or the lines no longer charged, refer to “How To Re-charge the Line Sets”. If the line set is too long for the application, refer to “How to Shorten the Line Sets” in Section 3.
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 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).
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]
operating gauge). The needle may drop approximately 1 psi (.09 bar), 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]).
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.
2-18
Part Number 020001552 5/11
Section 2 Installation

Start-Up

1. Turn on main water supply, set incoming regulator to 25 PSI (must be lower than CO2 supply pressure). 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.
Set Incoming Water to
Regulator to 25 psi
NOTE: Always set the water pressure to 25 psi first and only when no CO2 pressure is present. The CO2 pressure will bleed back and raise the water pressure gauge.
2. Turn on main CO
2 supply, set regulator initially to 26 psi,
can raise incrementally to 30 psi if their is no excessive foaming.
3. Set bag-in-box or syrup tank push pressure CO2 regulator to 35-40 psi.
Main CO2 Supply Set to 26-30 PSI

Preparing Ice Bank

BUILDING AN ICE BANK

1. At this time, fill the unit water bath tank to the top, or within 1/2” (1.3 cm) of the top minimum, of the overflow tube. Use a garden hose or another water supply to do this.
NOTE: A manual fill valve is incorporated into the water circuit to the carbonator tank. This valve can be used to manually add water lost for any reason. Do not leave this valve ON constantly, only use it for filling and topping off. The water bath must be drained, flushed, and refilled every six months.
2. Turn ON the switch labeled “Refrigeration”. Allow unit to run for about 15 minutes before proceeding to step 3.
3. Turn ON the switch labeled “Agitator”.
Note: Turn this switch OFF to perform any operations in the water bath area.
With water bath water temperature of 65°F (18°C), ice must begin to form on the evaporator coils in approximately 2 hours. The unit will build a full ice bank in approximately 4 to 6 hours (depending on ambient water temperature).

4. Before turning on the carbonator or circulator switch, verify that the pump box assembly has been mounted and connected to the unit and the appropriate syrup and water has been supplied.
5. Turn on the main water supply to the booster assembly. Verify the booster is plugged in and that the accumulator tank valve is open. (If the system has an optional “Out­of-Syrup” device, verify that it is unplugged.)
6. Verify the pump is running. Place the valve on the right side of the pump box in the purge position until all air bubbles have passed through the line. Turn the valve back to “dispense”. Plug the Out-of-Syrup device power cord into an appropriate wall outlet at this time (if supplied).
NOTE: Verify that the pump box holding tank is full before proceeding.
7. Turn on the circulator and carbonator switches. The carbonator must run for approximately 1 to 3 minutes and shut off. The circulator must run continuously. Verify that water is returning to the water bath through the return bulk head fitting.
Important
Wait until a thin layer of ice has begun to form on the evaporator before proceeding any further.
8. Go to the tower(s) and brix the valves. Using a syrup separator and volume cup, adjust the flow rate of the carbonated water to two fluid ounces per second. Then, using the separator and a brix cup, adjust the syrup flow rate for a ratio of carbonated water to syrup to 5 to 1.

• Has a round hole in the front and back panels with no edge trim to protect lines.
• End panel has two ovals in the rear of the panel with edge trim to help protect conduit lines.

Sequence of Operation

PRE-MIX REFRIGERATION UNIT Ice Bank Is Required
1. Check water bath for full ice bank.
2. The stabilized water bath operating temperature must be maintained at 33°F (0.6°C) to 35°F (1.7°C).
The following is a sequence of operations for the Multiplex Pre-mix Beverage equipment.
1. Once a drink is dispensed, the following will occur:
A. For a Syrup Tank System, the Pre-mix syrup is
manually mixed at the store. Pre-mix beverage is then transferred to a holding tank for supply to the Multiplex system.
B. For a Bag-In-Box System, pre-mix syrup is
drawn from a Bag-In-Box by means of a gas driven syrup pump.
2. The brix pump mixes a 5:1 ratio pre-mixer syrup and water into a 3 gallon holding tank located in the pump box (the 3 gallon tank is vented to atmosphere).
3. The carbonator pump (stainless) pulls the 5:1 pre-mix out of the 3 gallon holding tank and injects it into the pre-mix carbonator tank where the CO pressure is 35 psi (2.4 bar) on the tank.
4. The circulator pump runs continuously and circulates water bath water through the conduit to provide cooling for all drinks.

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.
1. Fill the refrigeration unit water bath tank with water to within 1/2” (1.27 cm) of the top of the overflow tube.
2. Open the manual water shut-off valve to the water cooled condenser (if applicable).
3. Turn ON the rocker switch labeled “Refrigeration” to begin building an ice bank.
4. Turn ON the rocker switch labeled “Agitator”.
5. Ice will begin to form on the evaporator coils in approximately 2 hours.
6. The refrigeration unit will build an ice bank in approximately 4 to 6 hours.
7. If optional CO installed on the refrigeration unit, refer to the installation instructions for operation and testing the circuits for leaks.
8. 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.
9. Turn on main water supply. Set incoming regulator to 55 psi on the CO2 panel; 25 psi for the Model 11M root beer system’s internal regulator (must be lower than CO2 supply pressure). 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.
10. Turn on main CO2 supply. Set regulator initially to 90 – 100 psi. For the Model 11 Root Beer system, set regulator initially to 26 psi; it can be raised incrementally to 30 psi if there is excessive foaming.
11. Set bag-in-box syrup tank push pressure CO2 regulator to 65 – 70 psi. For the Model 11 Root Beer system, set push pressure CO2 regulator to 35 – 40 psi.

PLACING THE CARBONATION 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. Turn ON the water supply to unit.
/Water Control Panel has been

4. Turn ON the switch labeled “Carbonator Pump”. Allow carbonator to run and cycle OFF.
5. Activate all valves until a smooth, continuous flow or carbonated water and non-carbonated water appear at the valves.
6. Turn ON switch labeled “Circulator”.
7. Allow at least 1 hour before proceeding to calibration instructions. You may complete the sanitizing instructions during this period.

Equipment Setup and Close Procedure

EQUIPMENT SETUP PROCEDURE

1. Ensure that all valve nozzles are attached to the valves.
