INSTALLATION INSTRUCTIONS

Water Inlet Connection:

This equipment is to be installed to comply with the applicable Federal, State, or local plumbing codes having jurisdiction. In addition:

1. A quick disconnect water connection or enough extra coiled tubing (at least 2x the depth of the unit) so that the machine can be moved for
cleaning underneath.

2. An approved back flow prevention device, such as a double check valve to be installed between the machine and the water supply.

The GB beverage dispenser is equipped with a ¼" Flare Water Inlet Fitting which is located on the left side in the back of the base (when looking at
the machine from the front).

HIGHLY RECOMMENDED:

A WATER SHUT-OFF VALVE and A WATER FILTER, preferably a combination Charcoal/Phosphate Filter, to remove odors and inhibit lime and scale
build up in the machine.
Note: In areas with extremely hard water, a water softener must be installed in order to prevent a malfunctioning of the equipment and in order not
to void the warranty.
After the machine has been unpacked and placed on a counter, pull out the stainless steel drip tray. It should contain the following:
A Set of 4 Adjustable Leveling Legs & Water Inlet Fitting.

START-UP PROCEDURE
Caution: Make sure that the Heater Switch, located behind right hopper with door opened, is in the OFF position.

1. Connect the ¼" dia. copper waterline to the ¼" flare water inlet fitting of the valve.

2. Plug the power cord into a proper receptacle.

3. Activate the Power Switch (Toggle Up). The door display panel, the red power indicator light and the green dispense buttons will light up and
the tank will start filling. Allow approximately 4-5 minutes for the tank to fill.

4. Activate the Heater Switch. Allow approximately 10-30 minutes for the water to reach a temperature of 195°F. The heat up time will
depend on the water inlet temperature, the input voltage and the wattage of the elements in the machine.

5. Place a 6 oz. or larger cup under the left dispense nozzle, press and hold the left dispense switch for 6 seconds. The machine will dispense
water at the rate of 1 oz. per second. Repeat it several times to check for consistent output. Repeat same for the other dispense switches.
This procedure checks that the dispense valves are not airlocked.

6. While the tank is heating up, remove the hoppers, load them with products and reposition them back in the machine. When the green ready
light comes on, the tank has reached its brew temperature and the machine is ready to dispense the first cup of Cappuccino.

To Dispense a Cup of Cappuccino or Coffee or Soup: Place a 8 oz. or larger cup under selected drink dispense nozzle.
For Manual units: Push and hold brew button until cup is 2/3 full
For Automatic units: Press and Release button
See Drink Strength Adjustments if different levels of drink strength are desired or Programming Dispense Volume if different cup sizes are
used.

DESCRIPTION AND LOCATION OF COMPONENTS

Note: Refer to Illustration A for description and location of COMPONENTS and CONTROLS.

1. HOPPERS. Depress the door latch on the left side of the door and pull door open to access the hoppers.

The hoppers hold up to 14 lbs. of Cappuccino product and up to 1.5 lbs. of freeze dried coffee product , depending on model number (see

spec. sheet).

To remove the hoppers simply swing the top compartment door open and lift out the hoppers.
To reposition the hoppers in the compartment, slide the hopper base back between the rails until the ¼" pin at the bottom of the hopper base

falls into the ¼" positioning hole of the compartment base cover.

2. RINSE SWITCH. With the door open, the rinse switch is located on the left side the first Whipper chamber.

In the RINSE position it disengages the hopper motors and allows only water to be dispensed.
It is used for flushing out the Whipper chambers and to adjust the water dispense valves for proper flow rates.

3. HEATER SWITCH. This switch is located inside the cabinet behind the right hopper, open door and remove right hopper to access
it. Its primary function is to shut off the heating element during the initial priming, start up operation of the machine, or whenever the tank is

being drained for service.

Note: On 120V, 1.8 KW and 120/240V, 3 KW machines, the Power Switch and Heater Switch must be ON in
order for the elements to operate.

4. POWER SWITCH. This switch is located on the left side of the splash panel below the door. On 120V, 1.8 KW and 120/240 or 240V, 3 KW

single element machines the power switch controls all power to the machine including the heater elements.

Note: On 120/240V, 6 KW

in order for the machine to be completely shut down.

5. WATER LEVEL CONTROLS:

Under normal conditions and operation, the water level in the tank should not drop more than ½" from the probe. If it does, the tank is not

refilling fast enough. Check the water line and water filter, they may need cleaning or replacing.

2. Push the dispense button and check the amount of product dispensed, amount of water dispensed, and time [use stop watch] to dispense that water.

3. The amount of of water dispensed in the measuring cup divided by the amount of time to dispense that water is the Water Flow Rate from Dispense Valve.
FOR CAPPUCCINO: The machine is factory adjusted to dispense 4-4.5 gr./sec. per OZ. Cup. [32 grams Product per 8 oz. cup]

Z:\DRAWINGS\NA000\NA33A-C-pages\NA33A-C-GB-MAN.dwg, 04/05/2002 01:06:07 PM, 1:1

The recommended throw is 28-32 grams per 8 oz. cup for Cappuccino, with 80 % fill.
FOR COFFEE: The machine is factory adjusted to dispense 0.3 gr./sec per OZ. Cup. [1.5 grams of coffee product per 5 oz. of liquid (in a 6 oz. cup).
The recommended throw is 1.5 to 1.8 grams per 6 oz. cup of Coffee, with 80 % fill.
FOR SOUP: The machine is factory preset to specified customer requirements, because the gram throw for each soup flavor and type varies
considerably with the consistency of each product. Adjustments can be made by the customer, as shown above.

For customer specified/special settings see inserts I, II, III, etc.

A) Water Inlet Valve Test

Turn power off. If the water level rises inside the tank, the Water Inlet Valve is
leaking. Disconnect wires from the Water Inlet Valve coil and connect a 2 wire line
cord to the terminals. Plug it into a 115V outlet. If water flows in and stops when
you pull it out, the Valve is working fine. Repeat this test a few times. The
problem may be in the Probe or Water Level Control Board. If the water does not
flow in when the cord is plugged into an electrical outlet, the Solenoid coil may be
damaged, opened or the valve may have an obstruction preventing the water from
flowing in. Clean or replace it.

A Check Valve is installed to prevent backflow.
To check proper function of Check Valve, disconnect water line from the Check
Valve, check for dripping from the disconnected end of the Check Valve. If it leaks
replace it.

B) Hi-Level Float Switch Test

The Float Switch acts as a guardian for the Solid State Level Control Board
and its Probe. If they malfunction and cause the water inside the tank to rise, the
Float Switch will prevent flooding by terminating the power to the Solid State
Control Board and the Water Inlet Valve. The correct mounting position of the
Float Switch in the tank is as shown in picture, with the magnets in the Float
Switch in the upper part of the switch.

After tank is full, unplug the wire to the Level Control Probe,
the water should run into the tank for a few more seconds until it reaches the Float
Switch and it should stop.
If not, and water starts coming out of the Breather tube, the Float Switch is
malfunctioning.

C) Probe Test
If lack of water persists, check the probe as follows:

Turn on the power and water supply. Check inside the tank to make sure the
water is not touching the Probe. Pull wire and terminal out of the Probe rod. If
water still does not flow after the wire is disconnected from the Probe, the
problem may be in the Solid State Water Level Control Board.
If water starts flowing into the tank, the Probe may be grounded, due to excessive
liming. Check with Ohm meter. Clean or replace probe.

D) Solid State Water Level Control Board Test
Check the Board as follows:

1. Make sure there is power input to the Board at the terminals 2 & 3

Your voltmeter should read 115 Volts. It should read the same at terminals 1 & 3.
This is the output power to electrify the coil of the Solenoid Valve to open it.
The lack of voltage at terminals 2 & 4 will indicate that the Board is not working
properly.

2. Make sure all wire connections to the Board are tight.

3. The grounding plate at the top, in the back of the board should be securely

grounded. The Board will not work or will work erratically, if it is not grounded
properly. If after this, the Board is still failing to open the Water Inlet Valve,
replace it.
