Service Manual 

Models: 

3205 Fresh Brew 

3206 Freeze Dry 

INTRODUCTION 

1.      The information contained in this service manual is applicable to the Hot Beverage Vending Machine. The Hot Beverage Vending Machine line consists of two types of coin-operated, microprocessor controlled, Hot Beverage Vending Machines that dispense a range of hot beverages in response to keypad selections.

2.      Two versions of each model are available:

4   Freeze-dried (INST) - Freeze-dried Coffee and Tea

4   Fresh Brew (SFB) -    Fresh Brew Coffee

3.      This manual uses the SFB version as the basis for examples. Where significant differences between versions exist this will be highlighted in the main body of the document. Due to customer requirements, however, some features may vary from those described, e.g. extras fitted, variations in programming etc.

4.      Cups from a cup drop mechanism are dispensed to contain the beverages.

5.      Selections are made on a 12 button keypad and an LCD display panel indicates status and beverage selection information.

6.      The status of the machine may be monitored and the configuration altered by accessing a menu of program options using both internal and external keypads. A number of sub-options are included under each option, the settings of which can be altered.

7.      A feature of the Hot Beverage Vending Machine is the mobile dispense head which moves to a parked position away from the cup port after each beverage is vended, preventing the possibility of any residue from the previous delivery cycle dripping into the next one.

8.      Hot Beverage Vending machines require a single-phase 120V electrical supply from a 12A outlet, and a cold water supply. These services connect to the machine through the rear of the cabinet.

9.      Maintenance of the coffee machine must be undertaken only by personnel who are authorized and suitably qualified. 

10.  The contents of this publication are presented for informational purposes only, and while every effort has been made to ensure their accuracy, they are not to be construed as warranties or guarantees, express or implied, regarding the products or services described herein or their use or applicability. The manufacturer reserves the right to modify the designs or specifications of such products at any time without notice.

SET-UP REQUIREMENTS 

Electrical Supply

• 110V, 60Hz, 12A fused
• 240V, 50Hz, 13A fused

The electrical outlet and supply circuit must be dedicated and isolated before connecting power to the machine. The electrical outlet must be within 6 ft (2 m) of the machine. Preferably, the switched outlet should be located behind the machine to prevent accidental damage or misuse. 

Water Supply

The main water supply must have 15-116 psi pressure. The water outlet must have a shutoff valve so that the water supply to the merchandiser may be turned off during servicing. The one-piece water supply hose with ½ inch female connector must be long enough to reach the machine. The water outlet should be located behind the machine to prevent misuse. 

Location

The Hot Beverage Vending Machine must be located close to the appropriate electrical and water outlets.  There must be a minimum of 4 inches (100mm) clearance between the rear of the cabinet and the wall to allow adequate ventilation. See Figure 4a.  If placing in a corner location, there must be at least 16 inches (406mm) of space to the right hand wall to allow the door to open properly.

Figure 4a. Distance From Wall 

Leveling

The Hot Beverage Vending Machine must be level for proper operation. Using a level as a guide turn the machine's leg levelers as needed until all levelers are touching the floor. If it is properly leveled, the vending machine should not "rock" or "teeter" on any of the levelers.  When the machine is level, the door can be opened to any position and not swing either way. Try the door at various open positions before deciding that the machine is leveled.

Connect Water

Before connecting the hose to the machine, flush the water supply system via the shutoff valve to remove any impurities which may have accumulated in the supply pipe or water hose.

The vending machine's water inlet - a standard 1/2 inch (13mm) male water hose connector - is located on the back of the machine. Remove the plastic protective cap by unscrewing it counter-clockwise. See Figure 4b.

Connect the water supply hose to machine water inlet and ensure that all fittings are tight. Turn on the water supply at the shutoff valve and check for leaks both outside and inside of the machine.

Connect Electrical

4   Plug the Hot Beverage Vending Machine power cord into a 110V, 60Hz, 12A (240V, 50Hz, 13A) switch supply socket. With the plug fitted to the socket, ensure that the cable is not stretched, distorted or hampered by any object.

Checklist

It is essential that the technician responsible for installing and commissioning the machine ensures the following:

1.      All electrical and water supplies are correctly and safely connected and that the water heater overflow pipe is not trapped or pinched (remove canisters to access and remove rear panel to check status of overflow pipe.)

2.      All covers, panels and access doors are in place and secured, and the machine is in a SAFE condition.

3.      The Operator is familiar with the SAFETY PRECAUTIONS for the machine.

4.      The Operator appreciates the importance of hygiene and regular cleaning of the vending machine.

With water and electricity sources connected to the machine, check the water heater operation as follows: 

1.      Press vending machine on/off switch (upper left side of interior back wall) to the ON position. Water will flow into the water tank. Wait approx. 1 minute and the water will shut off (safety feature). Then turn the power switch OFF, wait a few seconds and turn the power switch back ON. Water will continue to fill the tank. When water reaches the probe level, the heater will turn on as indicated by the heater indicator light (to the right of the on/off switch). There should be no water overflow into the waste basket.

2.      Ensure that the waste level probe is positioned in the waste basket.

3.     Press the vending machine on/off switch to the OFF position. 

NOTE: Water tank MUST be allowed to preheat for 15 to 20 minutes before filling coin changer or performing test vends because these will be automatically disabled if water temperature does not meet standard.
