INSTALLATION PROCEDURE
Counter-top Installation
NOTE: Optional 4-inch legs (p/n 3184) will elevate the unit 4 inches above counter (order 4 legs).
1. Place the unit on a level counter capable of supporting at least 400 pounds.
2. Remove drip tray and front access panel.
3. Turn power switch off then remove screw located next to the power switch and the screw at top of
front panel. Next, remove front panel, disconnect wires to valve key lock switch, and peal back
magnetic decals from the top. Lift off top center section.
4. Pull water, concentrate, and CO
2
lines through counter or wall. To comply with NSF International
requirements the unit must be sealed to the counter top and all access holes in the unit base must
be sealed, or the unit can be installed using the optional 4-inch legs (P/N 3184). Caulk/seal the unit
to the counter using Dow Corning RTV 731 or equivalent approved sealant.
5. Pull plastic “wire tie” to remove hitch pin from condenser fan motor assembly (this pin is only
needed during shipping).
6. Fill the water bath with clean water until it comes out the overflow tube. Make sure the overflow tube
is not blocked or plugged. Use low-mineral tap water, not distilled or deionized water.
NOTE: Water bath must be filled with water before the unit will run.
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 con-
denser fan motor will start. This three-
minute time delay will take place each time
electrical power to the Unit is interrupted.
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 differ-
ence in electrical resistance between the
water and the ice. When the ice on the
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 con-
denser fan motor off.
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 com-
pressor and the condenser fan motor.
