Location

:

Selecting a proper location for your Cambro Air Curtain Ultra Refrigerator is very important.

Always

:

Install to assure that unit is level.
Install to assure that unit is away from extreme heat.
Install to assure that unit is away from a steamer.
Install to assure that unit is NOT place near or under a ventilation duct or hood, (this will disturb the airflow of the Air Curtain and will 
hamper the performance of the unit).
Install to assure that unit is 6” minimum distance from back of unit to wall or obstruction (Ie: a wall).
Install to assure that the door(s) may open a minimum of 90 degrees.

Never

:

Never install equipment in an area of standing water.
Never install near or under a ventilation hood of duct return.
Never install equipment in an area not conductive to safe and proper operator use.

Clearance

:

It is important for proper operation and longevity of your Cambro Air Curtain Ultra that it have adequate provisions for air supply to the 
compressor. Allow approximately 6”-12” between the back grill of the unit and the wall for proper air flow. 

Installation Steps

:

1.  The outside carton has already been removed and inspected for damage. Remove all packing and strapping material from the exterior 

and interior of the unit. (Note: Packing material should be saved should there be any damage to the unit.)

2.  Remove the Cambro Air Curtain Ultra from the shipping skid. This is done by lifting the unit and rolling it off the skid. 

Do not lay the 

cabinet down.

3.  Tray slides have tabs formed into the side of the support. Simply put the tab into the square hole in the side of the cabinet and push 

down to seat. The supports can be installed in a horizontal plane of can be mounted in a slightly sloped orientation to cause the product 
to slide forward on the sheet pans. 

4.  The LED digital temperature display is powered up wen the unit is plugged in, it registers temperature in Fahrenheit degrees. The unit 

can be set up to show temperature in Celsius degrees. (See section 

VII

, ON /  OFF Switch for Instructions.)

The Air Curtain Ultra Refrigerator is specifically designed to hold 41°F (5°C) temperature or below for a minimum of 45 minutes and a maximum of 
90 minutes, dependent upon application and operating conditions. Examples that may alter performance include room temp, humidity, surrounding 
air exchanges, voltage, internal temperature of food product placed into the cabinet, profile of food product, and food product density.

When the door of the unit is closed, it operates as a force air refrigerator with a highly efficient refrigeration system that provides faster “pull down” 
and “recovery” times than standard refrigerators. When the door is opened, a series of blower fans create a “wall” of air and areas of pressure, 
localizing a unique pattern of air to keep the cold air in and the warm air out of the food zone and is specifically designed to help maintain and 
prolong the interior cabinet temperature and, thus, help maintain internal food product temperatures for extended periods of time with the door open, 
contributing to safer product storage during service hours. The Air Curtain seals itself around objects and is ideal for hospital and nursing home tray 
line / assembly line kitchen operations, flight kitchens, cafeterias, fast food and QSR applications. For best results, the air curtain was designed for 
“low profile” food products typical of these applications.
