1. Before connecting conduit, evaluate store situation and lay out how the conduit will be routed. Be sure to route conduit away from traffic areas, moving parts, and heat sources.
2. Physically route conduit per evalu a te d plan. Examine conduit routing and check for neatness, kinks, and interferences.

CONNECTING INSULATED CONDUIT AT THE UNIT

NOTE: List what color line was connected to which product so it can be connected correctly at the towers.
1. Route the conduit to the fron t op en in g an d int o the unit. Cut the insulation back from the lines inside the water bath.
2. Connect the circulating water by connecting one line to the circulating pump outlet line (3/8" barb) and clamp in place. Connect the other line to the bulkhead return fitting located by the agitator motor (3/8" barb) and clamp in place.
CONNECTING INSULATED SUPPLY LINES Connecting the insulated beverage conduit at the
refrigeration unit
1. Route the Multipar beverage conduit from the refrigeration unit to the dispensing station(s) according to the instructions enclosed with the conduit kit. Always route the conduit in a neat and orderly manner.
NOTE: Multipar conduit is color coded for easy identification of lines. When making connections always attach lines requiring the longest connection from the insulation first. The remaining lines can be trimmed as required to make the routing neat and secure.
3. Locate the two blue carbonated water lines of the Multipar conduit. Attach one of the blue lines to the tee fitting located on top of the carbonator tank. Attach the other blue line to John Guest elbow fitting on the stainless coil labeled “8”.
4. Locate the black plain water line of the Multipar conduit. Attach this line to the elbow fitting on the stainless coil labeled “W”.
5. The remaining lines of the Multipar conduit are syrup supply lines and must be attached to the appropriate elbow fittings on stainless steel syrup coils. Note the numbered lines attached to the opposite e nd of each syrup coil when making connections.
2. Insert the Multipar conduit into the outlet opening on the left hand side of unit. Conduit insulation must extend inside of opening in unit for proper operation of equipment.

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. T o 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.
NOTE: Y ou 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 1 1ft-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.
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

PRE-CHARGED REFRIGERATION LINE REQUIREMENTS

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.
1. Determine a position for installation that will allow access for maintenance and is free from obstruction. V erify 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.
Part Number 020002365 3/12 2-21
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.
Excess refrigeration tubing must be properly cared for before being connected to either the remote condenser or the refrigeration unit.
Installation Section 2
Important

CONNECTING THE PRE-CHARGED REFRIGERATION LINES

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 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 lin es 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.

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. Main power to unit must be on. Power delay of 30 seconds occurs when power applied. “Pd30”
3. Press COMP/AGIT switch on keypad display.
4. Agitator will come on immediately and compressor delay will start. “Cd99” will count from 180 to 0.
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).
7. Turn on the circulator and carbonator. 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.
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.

Installation Checklist

Check all fittings and conduit attachments for leaks. Check all insulated connections to make sure that they are sealed.
Observe the pump operations for leaks.
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 “Out-of-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.
Check the water bath for full ice bank.
The stabilized water bath operating temperature must be maintained at 33°F (.6°C) to 35°F (1.7°C).
Close water bath feeder valve completely.

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.
•CO
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 (44M, SC1000) or second carbonation pump (42M).
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.
