In-N-Out Burger NGF 255 Installation Manual Publication Number: 621058476INS - 4 -© 2011, IMI Cornelius Inc. INSTALLATION To the Installer !WARNING: This equipment must be installed to comply with the International Plumbing Code of the International Code Council and the Food Code Manual 01 the Food and Drug Administration (FDA). For models installed outside the U.S.A., you must comply with the applicable Plumbing/Sanitation Code for your area. Failure to comply could result in serious in jury, death or damage to the equipment. Water pipe connections and fixtures directly connected to a potable water supply shall be sized, installed, and maintained according to Federal, State, and Local laws. 1. Locate the dispenser indoors on a level counter top. A.LEG OPTION Unpack the four (4) legs and install them into the threaded holes provided in the bottom of the unit. The installer must provide flexibility in the product and utility supply to permit shifting the position of the dis- penser sufficiently to clean the area beneath it. The dispenser MUST be placed in a horizontal position. B.COUNTER MOUNTING The ice dispenser must be sealed to the counter. The template drawing (see Figure 2) indicates where openings can be cut in the counter. Locate the desired position for the dispenser, then mark the outline dimensions on the counter using the template drawings. Cut openings in the counter. 2. Apply a continuous bead of NSF International (NSF) silastic sealant (Dow 732 or equal) approximately 1/4- inch inside of the unit outline dimensions and around all openings. Then, position the unit on the counter within the outline dimensions. All excess sealant must be wiped away immediately. 3. The beverage tubes, drain tube and power cord are routed through the large opening in the bottom of the unit. See the MOUNTING TEMPLATE (See Figure 2) for locating the required clearance opening in the counter for these utility lines. 4. DRIP TRAY DRAIN ASSEMBLY (see Figure 3): Route the drain tube to an open drain with the end of the tube above the “flood” level of the drain. Use the tubing, fittings, clamps, and insulation provided with the Dispenser to assemble the drain. The completed drain line must pitch continuously downward and contain no “traps” or improper drainage will result. NOTE: IMI Cornelius Inc. recommends that a water shutoff valve and water filter be installed in the plain water inlet supply line. A Cornelius Water Filter (P/N 313860000) and QUICK DISCONNECT SET (P/N 313867000) are recommended. CAUTION:! Check the minimum flow rate and the maximum pressure of the plain water inlet supply line. MINIMUM FLOW RATE MUST BE AT LEAST 125-GALLONS PER HOUR. If flow rate is less than 125-gallons per hour, starving off the carbonator water pump will occur. Starving will allow the carbonator water pump to overheat causing the safety thermostat on the pump outlet to stop the water pump motor. Overheating could occur if the plain water supply line flow rate drops below 125-gallons per hour. INCOMING PLAIN WATER INLET SUPPLY LINE WATER TO PUMP PRESSURE MUST REMAIN A MINIMUM OF 10 psi BELOW THE CARBONATED CO2 OPERATING PRESSURE. (Example: Carbonator CO2 operating pressure is 75 psi and the maximum water pressure can be no more than 65 psi, etc.). Water over pressure (higher CO2 operating pressure) can cause carbonator flooding, malfunction, and leakage through the carbonator relief valve. If water is exceeding maximum pressure specifications, a Water Pressure Regulator Kit must be installed in the plain water inlet supply line. If fitting connector is not available, tap into the plain water supply line with a 3/8 flare saddle valve. 5. Locate the carbonator pump assembly and connect to power cord from the Ice/Drink Unit to the pump. The cord is connected to the unit’s electrical box and has an electrical connector on the end that plugs into a receptacle in the junction box at the carbonator pump assembly. Connect inlet water to pump and pump
