In order to meet the needs of high-volume operations, Viper has a powerful refrigeration system that provides its high capacity, which can generate a lot of heat. Often an HVAC system can work hard to remove that heat. The condenser and fan traditionally found on top of the viper equipment is placed remotely on the roof or outside of the store, so the heat is ejected from the building without adding any load to the HVAC system.
Installation requires the same considerations surrounding any application of remote condensing in other areas of your operations. A very tangible benefit of the remote condenser is immediately apparent with the reduction in heat load inside your retail space.
That makes a big difference to your customers and staff when it comes to noise levels and their physical comfort. The more Vipers you have utilizing remote condensers the higher the heat load reduction.
Page Syrup System The control system is set up by the service provider to perform the tasks necessary to keep the Viper unit operating correctly. There are up to five buttons and four directional arrows that may be used on a screen to activate and control vari- ous the functions of the system.
System Menus The system menu structure allows the user to control the unit through the control panel. Operational settings, optional parameters, troubleshooting and error information are controlled through this menu system.
To access the Unit Data menu, press the GO but- ton. Refer to Table 3, the Select menu, for button functions. Table 3. The possible messages from the control system and a description of the errors are shown in Table 6. The button functions are described in Table 7. Barrel viscosity is too high. Motor cannot rotate. Error Log Screen Table 8. Clock Setup Screen Table Setting Daylight Savings Time Once the date and time are set properly, daylight savings time settings can be done.
The Daylight Savings Time menu is shown in Figure Sleep periods and defrost lockouts may be programmed for any day of the week or for all days of the week, depending on business requirements. Use the left and right arrows to select the minute Some products are served best at a higher viscosity, while others require a lower viscosity for best quality.
The Viscosity menu, shown in Figure 17, allows the user to adjust the viscosity in each barrel to the optimum setting for each type of syrup. Use the Up and Down arrows to highlight the Select barrel desired barrel. To display U. Use the Up and Down arrows to highlight the desired Manual Diagnostic Screen The items shown in Table 25 are for the first barrel in the unit only.
The list includes additional components with their related barrel number, i. Totals Screen Table Display Value Description Shows how long the machine has been pow Page Motor Setup Menu Viper Low overrun Service Manual Motor Setup Menu Motor setup is initially done at the factory and does not need to be changed unless a barrel motor or barrel compo- nents are replaced, adjusted or removed and reinstalled.
This menu allows you to select different motor types for each barrel in the unit and run the calibration procedure on that motor. Calibration establishes a new baseline for the motor assembly. This allows the system to determine proper viscosity settings for the new motor. System Screen Table Page Dispensed Product Throughput Programmed Defrost Scheduling The control system in the Viper system includes a function to automatically defrost product in the barrel at programmed intervals based on the viscosity of the product.
Programmed defrosts are scheduled frequently to ensure that product quality within the barrel is maintained. Page Viscosity Setting Cornelius recommends that the viscosity settings be set at the lowest possible setting to achieve the desired drink qual- ity. In most typical installations using a sugar-based syrup, acceptable drink quality can be achieved by programmed vis- cosity settings in the range of for Viper. Normal equipment maintenance intervals are listed in Table It is recom- mended that a preventative maintenance procedure be performed every six 6 months.
Step Action Open the merchandiser Remove the filter, shown in Figure 32, by grasping the two tabs and sliding it straight out the front of the unit. Wash the filter with clean water. Shake out the excess water. Step Action Re-install the faceplate and replace the four 4 mounting nuts. Be careful not to over tighten the nuts or cracking of the faceplate may result.
Step Action Defrost freeze cylinders, shut unit down, disconnect electrical power from Unit. Perform the procedure in Table 41 to empty the barrels. Remove the hex nuts and flat washers securing the faceplate to the freeze barrel, then remove the faceplate from the barrel. Table When the barrel is defrosted, go to the Maintenance menu. If the security fea- ture is active, access the Maintenance menu by pressing and holding the far left and right buttons simultaneously for approximately five seconds.
Step Action Perform inspection and replacement of scraper blades. Perform a leak test on the barrel. Manually open the manual water flow valve to start filling the barrel with wash water. At the same time, open the faceplate relief valve until water comes out. The seal location is shown in Figure Step Action Remove the old seal and the spacer see Table Remove the new seal from its packaging. Clean the spacer. Slide the spacer with slots toward the motor housing over the motor shaft.
Perform the procedure in Table 47 to verify that the seal is installed properly and not leaking. When the seal passes the leak test, perform the motor calibration routine on page Step Action Perform the procedure in Steps 1 through 8 of Table Disconnect the motor from the circuit by unplugging the connector.
Step Action Remove the mounting screw from the base of the capacitor. Replace the capacitor. Reverse the procedure to install the new capacitor. Reconnect power to the unit. Refill the barrel with product. Step Action Disconnect power from the unit.
