By circulating heated air evenly across the open staging area, the Heated Landing Zone keeps sandwiches hot without drying or cooking. The Heated Landing Zone meets all McDonald’s standards for safety, efficiency, food safety, and cleanliness. 3.1 HLZ Installation/Setup Upon arrival, inspect the HLZ for concealed damage. Immediately report any damage to the delivering freight company. Claims must be filed within 15 days after receipt of the unit. Make sure that the unit is placed on an even surface and that the area surrounding the HLZ is free of clutter that would interfere with airflow. Install Optional Burger Bumper (Units Built Before 10/98) Optional Burger Bumper The burger bumper may be placed on either side of the HLZ to prevent pass through of product. Burger bumpers are provided by the KES. See Figure 1. Install Filter Screen (Units Built After 10/98) The filter screen is design to prevent debris from entering the computer Cowl Assembly and clogging the blower assembly. Simply fit the part on to the vent opening of the computer cowl assembly. The filter screen will snap into position. If equipped with an optional holding screw, tighten screw to pull the filter screen snug into position. Power Requirements Figure 1 Installed (before 10/98) Computer Cowl • Voltage – Two models are available: 208 VAC and 240 VAC* The filter screen snaps into place on rear of the air-intake tower. • Frequency - 60 Hz • Single Phase • 20 amp Service 3.2 HLZ Operation 1. Plug the unit into the power source. 2. See Chapter 5, Computer Operation and Programming, for proper computer setup and operation. 3. Place product in the HLZ in accordance with the restaurant’s established procedures. 4. When closing the store, remove all product from the HLZ and perform daily preventive maintenance in accordance with the MRC. Turn the computer OFF. DANGER If the 240 VAC model is operated on 208 VAC, the unit will heat slowly and may not reach maximum temperature. If the 208 VAC model is operated on 240 VAC, component damage is likely. To ensure proper operation, the power source should match the voltage on the rating plate on the bottom of the HLZ. ALL UNITS (CORD CONNECTED OR PERMANENTLY CONNECTED) SHOULD BE CONNECTED TO A GROUNDED POWER SUPPLY SYSTEM. THIS APPLIANCE IS EQUIPPED WITH A GROUNDING PLUG FOR YOUR PROTECTION AGAINST SHOCK HAZARD AND MUST BE PLUGGED INTO A PROPERLY GROUNDED RECEPTACLE. DO NOT CUT OR REMOVE THE GROUNDING PRONG FROM THIS PLUG. 3 HEATED LANDING ZONE CHAPTER 4: HLZ MODEL/COMPONENT IDENTIFICATION Heated air flows from the air heater/blower and heat rises from the heater plate.
