User manual SCOTSMAN RS160

[. . . ] RS160 and RS220 INTRODUCTION This service manual is intended as a reference for the installer, user, and service agent of this Scotsman Refreshment Stand. It includes the necessary information to install, start up, operate, clean and maintain this unit. TABLE OF CONTENTS SPECIFICATIONS . 22 This manual contains important information, read it before installation or operation. It marks important safety information on a hazard that might cause serious injury. June 1995 Page 1 RS160 and RS220 SPECIFICATIONS The term "Refreshment Stand" means a machine that stores ice in an insulated, sanitary container; upon demand it dispenses that ice into a cup or glass; it cools beverages using ice falling from the hopper onto a cold plate at the base of the hopper; and it dispenses beverages via post-mix or pre mix valves. [. . . ] General Information Dispensing Soda: To minimize foaming, a cup, 1/3 full of ice, should be filled at an angle so that the product runs down the inside wall of the cup, until the cup is nearly full. When the ice dispense lever or button is pushed, a motor begins to turn the rotor in the hopper, and a solenoid opens the ice chute door. NOTE: Periodically during the day, clean up the ice spilled in the drip tray. There is a timer in the control box that will activate the rotor in the ice bin every two hours. The amount of time that the rotor turns is factory set at 2 seconds, and is adjustable between one tenth of a second and 4 seconds. The reason for the timer is to stir the ice so that it doesn't fuse together after long periods in the bin. Cover Front Panel Soda Valves Ice Chute Splash Panel Drip Tray Ice Dispense Lever June 1995 Page 13 RS160 and RS220 FOR THE OPERATOR Daily Check 1. Make sure that the CO2 cylinder primary regulator assembly 1800 psi gauge is not in the shaded ("change CO2 cylinder") portion of the dial. The dispenser must always contain ice to have ice available for use, and to keep the syrup product cool. If there is no ice in the hopper, it will take about 1/2 hour after ice is added for the cold plate to cool off properly. NOTE: After ice is loaded into a WARM hopper, dispense several containers of ice: this helps disperse the ice across the cold plate. Keep the cover in place, and check the ice supply regularly during operating hours. At the end of the day: Remove soda valve nozzles and diffusers, clean them and soak in hot water. Remove the grill from the drip tray, clean the drip tray, grill and splash panel, make sure the drain is open by pouring hot water into the drip tray. Return the grill to the drip tray. Ice hopper contains parts that can move at any time and will cause injury if hands are in the way. Do not remove cover until the unit has been unplugged from electrical power. The ice must be broken up in the bags first before adding to the hopper. Large chunks of ice can NOT be dispensed. Pour Hot Water Down Drip Tray Every Day To avoid a delay in cooling soda at the beginning of the business day, make sure that the hopper is kept at least 1/4 full of ice to keep the cold plate (and the soda product) cold overnight. June 1995 Page 14 RS160 and RS220 FOR THE OPERATOR Replenishing CO2 Supply Note: When indicator on CO2 cylinder regulator 1800 psi gauge is in the shaded area, the cylinder is almost empty and should be changed. Slowly loosen CO2 regulator assembly coupling nut allowing CO2 pressure to escape, then remove regulator assembly from CO2 cylinder. If the CO2 tanks falls over, valve can become damaged or broken off, this can cause serious injury. To avoid personal injury and/or property damage, always secure CO2 cylinder with a safety chain to prevent it from falling over. Make sure gasket is in place inside CO2 regulator coupling nut, then install regulator on CO2 cylinder. Open (counterclockwise) CO2 cylinder valve slightly to allow lines to slowly fill with gas, then open valve fully to back seat valve. [. . . ] Water, oil, or dirt in CO2 supply No product (only water) dispensing from all valves Dispensed product comes out of the dispensing valve clear, but foams in the cup or glass 1. Use clean cups or glasses June 1995 Page 20 RS160 and RS220 ELECTRICAL SEQUENCE Refer to the wiring diagram. Ice Vending: Ice is dispensed as long as the ice vend lever or push button is pushed, or until the hopper is empty of ice. · When the ice vend lever or push button is pushed, the vend switch closes, and makes a circuit to the coil of relay A.
