After turning the ON/OFF switch to ON the unit’s compressor 

will begin operating. Delfield display cases are designed to 

maintain an operational temperature of 36°F to 40°F (2°C 

to 4°C) in both the display (F5 and F15 Series) and storage 

areas (F15 Series only).
Continuous opening and closing of the doors will hamper the 

unit’s ability to maintain operational temperatures.

If an excessively dirty condenser is the cause of the        

refrigeration system high pressure shut down, see “Cleaning 

the condenser” on page 7. Make sure the condenser is   

thoroughly clean before resetting the lock-out device.

Low pressure cut in at 20 psi.
Low pressure cut out at 5 psi.
Differential setting of 15 psi.
High pressure cutout at 450 psi.

Stainless Steel Care and Cleaning
To prevent discoloration of rust on stainless steel several important 
steps need to be taken.  First, we need to understand the properties 
of stainless steel.  Stainless steel contains 70-80% iron which will 
rust.  It also contains 12-30% chromium which forms an invisible 
passive film over the steels surface which acts as a shield against 
corrosion.  As long as the protective layer is intact, the metal is still 
stainless.  If the film is broken or contaminated, outside elements can 
begin to breakdown the steel and begin to form rust of discoloration.

Proper cleaning of stainless steel requires soft cloths or plastic 
scouring pads.

Cleaning solutions need to be alkaline based or non-chloride 
cleaners.  Any cleaner containing chlorides will damage the 
protective film of the stainless steel.  Chlorides are also commonly 
found in hard water, salts, and household and industrial cleaners.  If 

cleaners containing chlorides are used be sure to rinse repeatedly 
and dry thoroughly upon completion.

Routine cleaning of stainless steel can be done with soap and water.  
Extreme stains or grease should be cleaned with a non-abrasive 
cleaner and plastic scrub pad.  It is always good to rub with the grain 
of the steel.  There are also stainless steel cleaners available which 
can restore and preserve the finish of the steels protective layer.

Early signs of stainless steel breakdown can consist of small pits 
and cracks.  If this has begun, clean thoroughly and start to apply 
stainless steel cleaners in attempt to restore the passivity of the steel.
