Warning

Electrical

GENERAL

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

MINIMUM CIRCUIT AMPACITY

The minimum circuit ampacity is used to help select the wire size of the electrical supply. (Minimum circuit ampacity is not the beverage/ice machine’s running amp load.) The wire size (or gauge) is also dependent upon location, materials used, length of run, etc., so it must be determined by a qualified electrician.

ELECTRICAL REQUIREMENTS

Refer to Ice Machine Model/Serial Plate for voltage/ amperage specifications.

VOLTAGE

The standard voltage for MDH Series dispensers is 120VAC-60Hz. A power cord is provided with 120VAC60Hz models only. MDH Series dispensers use a 1/7 hp gearmotor.

MINIMUM CIRCUIT AMPERAGE CHART

Due to continuous improvements, this information is for reference only. Please refer to the dispenser serial number tag to verify electrical data. Serial tag information overrides information listed on this page.

Grounding Instructions

Risk of electrical shock. Connect to a properly grounded outlet only.

This appliance must be grounded. In the event of malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This appliance is equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Improper connection of the equipment-ground ing conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment grounding conductor. If repair or replacement of the cord or plug is neces sary, do not connect the equipment-grounding conductor to a live terminal. Check with a qualified electrician or serviceman if the grounding instructions are not completely understood, or if in doubt as to whether the appliance is properly grounded. Do not modify the plug provided with the appliance — if it will not fit the outlet, have a proper outlet installed by a qualified electrician.

SYSTEM PRESSURES

1. Incoming tap water - must be at a minimum dynamic pressure of 40 psi and maximum static pressure of 70 psi.

If incoming water pressure is under 40 psi dynamic, a water booster is recommended. If incoming water pressure is over 55 psi, a water regulating valve is recommended.

NOTE: For water booster setups, connect directly to the incoming water to the unit. A regulator m ay be needed to maintain 40 - 55 psi to the carbonator or water may be routed around the booster to the carbonator. If water pressure is too high to the carbonator poor drink carbonation can result.

Water boosters are preset to turn on at 65 psi and of f at 85 psi.

2. BIB pressure gauge must be set for 75 psi or according to your line run.

Starting Your Beverage System & Dispenser

Upon completion of the beverage dispenser and / or system installation, all tubing, dispenser, and system components must be cleaned and sanitized prior to use.

NOTE: At installation, equipment, dispensers, and tubing get moved through many environments, dirt, dust, chases, insulation, drywall, etc. It is an important procedure and best practice to address cleaning to deliver the best quality drink to your customer.

Clean and sanitize the water and syrup circuits according to instructions provided in this manual. Clean and sanitize the dispenser components according to instructions provided in this manual. Seal to counter top when no legs are use d with the unit. Consult and use local health codes if a discrepancy occurs between this manual and your local health codes.

3. Carbonator Pressure gauge (Use Preset Regulator):

- Cold Carbonation set for 75 psi.

- Ambient systems must be set at 90 psi to 105 psi.

NOTE: For models with flavor shots you want to achieve .5 oz (14.787 cc) a second dispense, adjust secondary regulator or flow controls accordingly.

ICE RECOMMENDED FOR DISPENSING

Dispensers are designed to dispense hard, cube ice up to one-inch square. The ice shapes and sizes listed above are recommended for dispensing. Warm “Super Cooled” Ice Before Dispensing: “Super Cooled” ice is not recommended for dispensing. “Super cooled” ice is ice that has been stored in freezers below 32°F. must it be necessary to temporarily use “super cooled” ice, allow the ice to warm at room temperature for 25 to 30 minutes before placing the ice in the dispenser.

ICE STORAGE AND DISPENSING

As the customer presses the rocking chute, the arm at the top left rear of the chute pushes upward on the door lock. The door opens until it contacts the stops in the mounting brackets. The plastic arm on the ice ch ute also activates the lever of the ice dispensing switch. When activated, the micro switch starts the gear motor. The gear motor turns the paddle wheel and agitator arm.

The paddlewheel carries ice. Periodic agitation is standard on the 30" and larger dispensers. During periodic agitation, the paddle wheel and agitator turn for approximately three seconds every three and one halfhours. The door lock prevents ice from being dispensed during the agitation cycle.

BEVERAGE VALVES

Post-mix beverage valves are designed to precisely meter the flow of both water and syrup to obtain the proper mixing ratio. The syrup and soda wate r components of the post-mix beverage are mixed as they leave the beverage valve.

ROCKING CHUTE ICE DISPENSING

As the customer presses the rocking chute, the arm at the top left rear of the chute pushes upward on the door lock. The door opens until it contacts the stops in the mounting brackets. The plastic arm on the ice chute also activates the lever of the ice dispensing switch. When activated, the micro switch starts the gear motor. The gear motor turns the paddle wheel and agitator bar.

CARBONATION

The purpose of the carbonator is to take regular tap water at street water pressure (minimum 20 PSI, maximum 80 PSI, dynamic or flowing pressure) 1/2" water line and increase the water to beverage system pressure (usually 100 PSI). This water is then combined with the CO

gas. Because the water and gas are at the

same pressure, the CO Chilling the mixture before dispensing will assist in locking the carbon dioxide into the water. After dispensing, the CO The CO

will gradually leave the liquid due to pressure

and temperature changes.

Components

The components of the carbonator are: water pump, an electric motor to operate the pump, carbonator tank where the water and CO

Operation

Carbon Dioxide (CO

) leaves the storage tank and

arrives at the carbonator tank through the gas inlet. Water supply enters the carbonator pum p inlet at regular street water line pressure (minimum 20 PSI, maximum 80 PSI, dynamic or flowing pressure). The water pump increases the pressure of the water, which allows the water to flow into the carbonator tank. The CO

and the

water mix together in the carbonator to produce the carbonated water that is then sent to the soda dispenser.

The agitation of the water and CO

together in the tank

under high pressure creates the soda water. The quality of carbonation (percent of CO

mixed in the water)

increases as the water temperature decreases and exposure time increases.

The water level in the carbonator tank is controlled by a water level control in the tank. This control turns the pump motor off and on to maintain a preset level of liquid in the tank. The water level control may be electronic probes or a mechanical float.

SYRUP DELIVERY SYSTEM

Your syrup location can vary depending on the volume of beverages served and ease of accessibility. Your beverage system may set in a back storage room or under the counter of the dispenser. Configurations are almost limitless. Check the temperatures expected for the storage location. Adverse temperatures can affect the storage and quality of beverage products. It is recommended the temperature of storage location should not fall below 40°F (4°C) or rise above 90°F (32°C).

BACK ROOM PACKAGE

1. Incoming tap water - should be at a minimum dynamic pressure of 40 psi and maximum static pressure of 70 psi.

2. Carbonator Water pump motor - Powers the water pump. The water pump motor is part of the carbonator pump deck.

3. Carbonator Water pump - Pumps t ap water into the carbonator tank. The water pump is part of the carbonator. The incoming water for the carbonator must be first run through the pump before connecting to the proper cold plate inlet.

4. Internal/External Carbonator tank - Combines CO

gas and tap water to form carbonated water.

The “carbonator” is the carbonator tank, water pump and water pump motor.

5. CO

gas flows through the

primary pressure regulator.

6. BIB pressure gauge - Set for 75 psi. Indicates CO pressure going to B-I-B pumps.

7. Primary pressure regulator - Lowers the CO pressure, to 100 psi, so the CO

gas will be at the

gas

proper pressure to enter the carbonator regulator.

8. Lowered outgoing pressure - Set for 75 psi. Gauge indicates lowered outgoing pressure from the CO

cylinder after being routed through the primary

pressure regulator at 100 psi.

9. Secondary pressure regulator - Lowers the CO gas pressure before the CO pump. CO

pressure activates the syrup pump.

RACKING

Regardless if you are working on a B-I-B or Figal system, a place will be designated for placement of the product. A rack (or shelf) system affords systematic placement and complete usage of the beverage paid for . The B-I-B rack allows the boxes to lay properly for syrup dispersal. Please check with your B-I-B syrup supplier. Some boxes must be slightly tilted down, while others may be in virtually any position. The Figal tank rack keeps the newer and full ta nks organized at one end of the beverage line with the partial tanks at the other .

B-I-B

The Bag-In-Box system refers to a plastic disposable bag. The B-I-B normally contains 5 gallons of syrup, however some locations offer 2-1/2 gallon B-I-B units. This plastic bag is then held inside a cardboard or other container . B-I-B systems are for post-mix applications only .

PUMPS

The syrup in a B-I-B system is delivered to the beverage system through gas operated pumps. These pumps extract the syrup out of the bags, forcing the syrup throughout the system.

AUTO BAG SELECTORS

These are used on higher volume B-I-B systems where two or more bags of the same product are connected to one pump and one system. An auto bag selector is essentially a valve that automatically changes from one bag (or series of bags) to another bag (or series of bags) of syrup as the bags empty, allowing a constant flow of product.

FIGAL SYSTEM

Figal refers to the stainless steel tanks of pre-mix beverage or post-mix syrup. A small CO

tank pushes the beverage out of

the figal tank.

FIGAL T ANKS

The stainless steel Figal beverage tanks are easy to store and connect. When using the Figal tanks:

• Use a gas connector for the inlet fitting of the tank.

• Use a syrup connector for the outlet fitting of the tank.

• If more than one Figal tank is connected in series, when changing tanks, remove the tank closest to the original gas inlet while adding the new tank to the connector closest to the syrup outlet.

Most Figal tanks have a self-closing valve on the tank as well as the gas and syrup connectors. This allows the operator of the system to change tanks without having to shut down the entire system. With this type of connector, push down on the connector while pulling up on the snap ring around the opening of the connector. Then simply pull the connector of f the tank.

NON-ADJUSTABLE AGITATION TIMER

The timer is non-adjustable and is set to agitate the ice for 3 seconds every 3.5 hours. Activating the dispenser will reset the timer. Af ter 3.5hours of non-use, the timer will energize the dispenser motor.

The LED tells the technician in which mode the timer is operating. Rather than a jumper pin, this timer has a female spade connector that must be connected to terminal number 6.

When this jumper is in place, the LED will blink at one second intervals, this is the run mode.

When the jumper is open, the LED will flash every 0.4 second. This is the test mode and the timer will cycle every 55 seconds in test mode. If the timer is left in test mode, it will automatically reset to run mode.

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

2. Disconnect the “syrup-line side” of the bag-in-box 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.

• 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 to hot tap water for rinsing.

• Bucket 2 — mild detergent and warm to hot water.

• Bucket 3 — mix a solution of unscented bleach (5% Na CL O) or commercial sanitizer and warm to hot water. Mixture must supply 100 PPM available chlorine (1/4 oz. bleach to 1 gallon water).
