SAFETY PRECAUTIONS

This unit has been specifically designed to provide protection against personal injury. To ensure continued protection observe the following:

Disconnect power to the unit before servicing following all lock out/tag out procedures established by the user. Verify all of the power is off to the unit before any work is performed.

Failure to disconnect the power could result in serious injury, death or equipment damage.

Always be sure to keep area around the unit clean and free of clutter. Failure to keep this area clean may result in injury or equipment damage.

SHIPPING AND STORAGE

Before shipping, storing, or relocating the unit, the unit must be sanitized and all sanitizing solution must be drained from the system. A freezing ambient environment will cause residual sanitizing solution or water remaining inside the unit to freeze resulting in damage to internal components.

MOUNTING IN OR ON A COUNTER

When installing the unit in or on a counter top, the counter must be able to support a weight in excess of 430 lbs. to insure adequate support for the unit. FAILURE TO COMPLY COULD RESULT IN SERIOUS INJURY, DEATH OR

EQUIPMENT DAMAGE.

NOTE: Many units incorporate the use of additional equipment such as icemakers. When any addition equipment is used you must check with the equipment manufacturer to determine the additional weight the counter will need to support to ensure a safe installation.

CO2 (CARBON DIOXIDE) WARNING

CO2 displaces oxygen. Strict attention MUST be observed in the prevention of CO2 gas leaks in the entire CO2 and soft drink system. If a CO contaminated area before attempting to repair the leak. Personnel exposed to high concentrations of CO experience tremors which are followed rapidly by loss of consciousness and DEATH.

GLOBAL ICE BANK CONTROL (GIBO) THEORY OF OPERATION

Once electrical power is supplied to the Unit, the agitator motor will start. There will be a three-minute time delay before the refrigeration compressor and the condenser fan motor will start. This three-minute time delay will take place each time electrical power to the Unit is interrupted.

evaporator coil becomes thick enough, it covers the three stainless-steel pins on the ice bank control probe. The control module senses there is enough ice and turns the refrigeration compressor and the condenser fan motor off.

The Unit will continue to operate until ice covers all three stainless-steel pins on the ice bank control probe. The ice bank control module senses this by measuring the difference in electrical resistance between the water and the ice. When the ice on the

NOTE: Make sure that the electrical power circuit breaker is switched off or the fuse removed.  Before connecting electrical power to the unit, refer to nameplate to verify the power requirements.

A. Remove the following:

• front merchandiser by removing two screws on the top and lifting up

• key switch wires

• hood by removing two screws on the top and lifting up and forward.

B. Remove second valve from the left to facilitate routing of the new cord.

C. First route the new cord up behind the valve panel and through the cutout in the pump deck. Use the

already attached wire tie/fastener on the deck to secure the cord.

D. Connect cord to the receptacle on the refrigeration deck.

E. Turn the circuit breaker on and then the units power switch. Check to see that the agitator motor has

started. After about three minutes the compressor should start. If the agitator or compressor do not start call Technical Services.

The Unit remains turned off until the ice bank control three stainless-steel pins are free of ice. Once this happens, the ice bank control module starts the refrigeration compressor and the condenser fan motor.

CONNECT CONCENTRATE AND WATER LINES

1. Route concentrate and plain water lines from the back side of the unit and under the unit to the front. Connect them to the appropriate inlet connections.

NOTE: If water supply pressure to the unit is less than 40 psi, a water pressure booster is required. If water supply pressure to the unit is more than 50 psi, a water pressure regulator must be installed in the supply line.

NOTE: A water shutoff valve and water filter in the water supply line are recommended.

2. Make the connection behind the splash panel to the marked 3/8 water tubes.

3. Connect optional drip tray drain hose (if used). Be sure the knock-out in the drip pan has been removed if drain hose is used.

4. Bleed each valve into a bucket until water comes out.

5. Be sure that all concentrate sources are connected and on. Bleed each valve into a bucket until concentrate comes out.

6. Reinstall drip tray and position water bath overflow hose in drip tray indent.

Non-Carbonated Impulse Installation & Operational Manual

7. Check the system for gas leaks by pressurizing the system and then turning off the cylinder valve. Wait a couple of minutes and check the cylinder gauge to see if the pressure has dropped.

8. Check the system for water and concentrate leaks.

ADJUST WATER-TO-CONCENTRATE RATIO

1. Remove valve front cover and install concentrate diversion assembly in place of nozzle.

Figure 3.

2. Adjust carbonated water flow to the desired rate (such as 2.50 oz./sec.).  Turn the adjuster 1/4 of a turn at a time and recheck the flow.  To increase flow turn clockwise.

3. Adjust the concentrate-to-water ratio of each valve using the concentrate adjuster on the left side of each valve. Hold cup under valve and dispense beverage for a specific time (such as 4 seconds).

ADJUSTING FLOW RATES

Flow rates of the water and concentrate are adjusted based on the desired ratio. For example: if the desired ratio is 5:1, then the flow rate of the water is 5 times that of the concentrate.

If the desired finished drink flow rate is 3.0 ounces per second, then the water flow rate is 2.5 oz./sec. and the concentrate flow rate is 0.5 oz./sec. (The water at 2.5 oz./sec. is five times the 0.5 oz./sec. concentrate flow rate.)
