Defrosting may be accomplished with the aid of a hair dryer, plastic scraper or by merely 
letting the cabinet remain open until the walls are cleared.  Care should be taken not to 
puncture the interior walls or remove paint from the walls during this procedure.   
 
Be sure to disconnect power from the cabinet prior to starting defrost operation.  After the 
cabinet is completely defrosted, wash thoroughly, remove defrost water (Hussmann 
dipping cases are provided with an outside drain located on the operator’s side of the case 
base to assist you in this operation), wipe the interior dry, and turn the power back on.   
 
Be sure to allow the cabinet to cool down to its operating temperature before reloading. 
 
CONDENSING UNIT – 
 
The condensing unit is mounted on a slide out base, accessible by removing the rear serving 
side access panel.  The condenser is of the bare tube design.  The condenser fan motor 
draws the air through the rear access panel, across the compressor and discharges back out 
the rear access panel.   
 
CLEANING THE CONDENSER –  
 
To clean condenser, a soft, nylon brush should be used to loosen dirt and lint.  Then 
vacuum up the dirt or blow condenser out with a high-pressure gas such as nitrogen.  
Never use a wire brush to clean condenser tubes. 
 
CLEANING EXTERIOR / INTERIOR – 
 
When cleaning the exterior of the cabinet use a soft cloth or sponge with water and mild 
detergent.  Rinse and wipe dry. 
 
For cleaning the interior of the product compartment, a built-in drain has been provided 
with a standard hose fitting located at the front of the cabinet in the base area.  Disconnect 
the electrical power and allow cabinet to warm to above freezing temperature.  Use a soft 
cloth or sponge with a mild detergent to wash the interior.  Wipe dry before restarting the 
cabinet.  Allow the cabinet to cool down to proper temperature before reloading product. 
 
 
SERIAL PLATE LOCATION –  
 
The serial plate is located on the interior left wall of the cabinet. This plate contains all 
pertinent information such as model, serial number, amperage rating, refrigerant type and 
charge, etc.  The specific charge is 29 oz., of R-404a.
