3. HEATED LANDING ZONE 

 

The 

Heated Landing Zone

 or 

HLZ 

is designed to hold assembled sandwiches.  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. 

 

4. 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 air flow. 

 

INSTALL OPTIONAL BURGER BUMPER (Units built before 10/98) 

 

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.

Cowl 

* 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 probable.  
To ensure proper operation, the power 
source should match the voltage on the 
rating plate on the bottom of the HLZ. 

The filter screen snaps into place on rear of the 
air-intake tower.
