TABLE OF CONTENTS 

Please have the model and serial numbers if you need service and parts information. The numbers are on the identification plate located on the back side of the cabinet of the vending machine.  

INTRODUCTION  

This manual contains instructions, service and installation guidelines for the SZF/DZF Vendor. Please read this manual thoroughly and follow instructions. The initial set-up of a vending machine is a very important step of insuring that the equipment operates in a trouble-free manner.  

The SZF/DZF Vendor can be factory configured to have two temperature compartments (top and bottom) in a single vending machine separated by moveable air deflector and insulating barrier. The vending machine has an air duct that runs up and down on the back inner wall of the cabinet. Each compartment can have 2 to 4 moveable trays and a total of 6 trays for the  

entire vending machine. The vending machine will maintain up to 13°C (23°F) of separation between the compartments at an ambient range of 4.4 °C-37.8°C (40°F-100°F). The temperature setting for both compartments are set at the controller (program).  

The top compartment can have an optional heater system to provide further temperature separation across varying ambient temperatures. This option consists of a heater, temperature sensor, air circulating blower and a relay (RELAY3).  

The bottom compartment has a temperature sensor and an insulated refrigeration system. Cool air is drawn from the refrigeration system's evaporator coils through the air duct and is deflected into the bottom zone by a moveable air deflector. There are openings in the bottom trays to allow air to circulate around the products.  

All programming of the pricing, vend functions and features are also done at the controller. Changes can be made without any additional accessories or remote parts. Selections can be priced individually from $.05 to $999.95 in five cent increments (US currency). When adapted to accept international or foreign currency, the maximum vend price will be 255 times the smallest denomination of coin being accepted. Cash accountability records, total cash transactions, total vend cycles performed by the vendor, information for individual selections, complete rows or total machine can be compiled and used for inventory and ordering records. Electrical malfunctions are recorded and displayed when the vending machine is placed in the Service Mode. Non-functional motors or selections are indicated. Each selection has an individual motor. Functional selections will continue to operate if other motors become nonfunctional.  

The vending sequence is "first-in, first-out" for each selection, permitting stock rotation to maintain fresh products in the vending area.  

Each SZF/DZF Vendor has the capability of supporting a "satellite" vending machine, such as a CB300-SAT, Can Vendor or Food Merchandiser (Menu Mart II). The satellite vendor utilizes the SZF/DZF Vendor vendor's existing controller, coin mechanism, bill validator and keypad to perform the vend functions they require. For details on the satellite vendor, refer to the Service Manual pertaining to the specific vendor for installation instructions.

Leave at least four (4") inches of space between the back of the vending machine and any wall or obstruction for proper air circulation. Use the Flip Down Stand-Off Bracket (See Figure 11 c on page 30).  

LEVEL THE VENDOR  

All levelers must touch the floor. The vendor must be level for proper operation, cabinet to door alignment and for acceptance of coins through the coin mechanism.  

GROUNDING (EARTHING) & ELECTRICAL  

Before connecting the vendor, the integrity of the main electrical supply must be checked for correct polarity, presence of ground (earth) and correct voltage. Please refer to the Safety Manual and Installation Guidelines Manual (P/N 4206816) that shipped in the service package with your vending machine. These checks should be repeated at six (6) month intervals with the routine safety electrical testing of the vendor itself.  

If the receptacle is not properly grounded or polarized, you should contact a licensed electrician to correctly polarize andlor ground the receptacle to ensure safe operation.  

A noise suppressor has been installed in this vending machine to compensate for any mains signal noise that could interfere with the normal operation of the controller.  

For proper operation of any equipment utilizing electronically controlled components, the equipment should be placed on an isolated or dedicated noise ­free circuit, properly polarized and grounded.

DOOR GLASS HEATER SWITCH  

This switch is normally turned off to conserve energy. Turn the switch on only if the vendor is in a humid location and water condensates on the glass. See Figure 4h.  

ADVANCED POWER MANAGEMENT  

This feature is available on software version 67256 only: It uses INTERVAL  1 of the SHUTDOWN mode to activate the ADVANCED POWER MANAGEMENT (APM) feature while still keeping intervals 2 thru 4 available for use as vending shutdown timers. The APM feature reduces the energy consumption of the refrigeration system between the hours of 12:00 am to 6:00 am by increasing the SET POINT for SENSOR1 TO 10˚C (50˚F). Upon entering the SHUTDOWN menu, the display scrolls  

   [ENERGY TIMER 1 OR SHUTDOWN TIMER 2-4]. Once the enter key is pressed, the SHUTDOWN sub-menus will work as currently programmed. The SHUTDOWN mode must be turned on and the correct date and time must also be set for the APM and SHUTDOWN timer intervals to work correctly. When the APM is active, vending is allowed and the point of sale message is displayed as  

 **Thank You **Energy Saver mode active** 

LOADING PRODUCTS  

All trays of a single zone and all trays in the bottom compartment of dual zone machines and are for can, bottle or food products requiring cool temperatures when vended. The trays in the top compartment of dual zone machines are designed for snacks, chips and chocolate products requiring less cool temperatures.  

Load product from front to back making sure all items fit freely between the auger spaces. Do not attempt to force oversize items or packages into the spaces. Do not skip a space. Place the product on the bottom of the compartment on the product augers with the label facing the front of the vending machine for easy identification by the customer. See Figure 5a.  

SNACK/CANDY/FOOD TRAY OPTION  

To load products, lift the tray slightly and pull forward until the tray stops. The trays tilt for easier loading.  

The size of the item being vended must be larger than the diameter of the auger being used to vend properly.  

Undersize items could cause vend problems. If the product does not fit the auger properly, use a different pitched auger. See Table 1 for augers available from your distributor or service entity.
