INSTALLATION
!
WARNING:
It is the responsibility of the installer to ensure that the water supply to the dispensing equipment is provided with protection back flow by an air gap as defined in ANSI A 112.1.2-1979; or an approved vacuum breaker or other such method as proved effective by test and must comply with all federal, state and local codes.
Failure to comply could result in serious injury, death or damage to the equipment.
Water pipe connections and fixtures directly connected to a potable water supply shall be sized, installed and maintained according to Federal, State and Local laws.

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
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.
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

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.

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.)
