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.

For proper start up, verify that the thermostat is in the OFF position 

prior to connecting the unit to its power source.  This will eliminate 

any possible electrical issues.  Failure to start the unit with the 

thermostat in the OFF position could lead to motor failures as well as 

other electrical component failure.  

The thermostat also has an OFF position that disconnects power to the 

condensing unit, keep in mind the evaporator fans and lights will still 

have power while the thermostat is in the OFF position.   On freezer 

units the lights and defrost timer will still have power as well as the 

condensate  heating elements.  During normal operation the freezer 

temp is preset at approximately 0°F and the refrigerator is preset at 

approximately 37°F.  

After plugging the unit in and turning the power switch to ON the 

unit will then begin to operate.  For standard units verify that the 

thermostat is in the off position prior to plugging the unit in.  Once 

power is connected the thermostat can be set to the 3 or 4 position 

for normal operation.  

1.  Turn the main power switch, located on the top of the control box 

to the ON position.  Turn the night position switch, on the front of 

the control box, to the ON position. 

2.  Adjust the temperature control to the desired temperature.

The green area on the scale represents the optimum food holding 

temperature zone of 150°F to 170°F (66°C to 77°C).  When the cabinet 

is warmed up and the temperature stabilized, the cabinet temperature 

will normally stay within a few degrees of the temperature control 

set point.  The display shows a precise measurement of the actual air 

temperature within the cabinet, not an average reading.  Therefore, 

it is not unusual to see the temperature vary when the doors are 

opened.  The quick response of the heating system combined with the 

precision temperature readings provide very accurate control of the 

cabinet temperature.

3.  The light switch (on the glass door models only) controls the 

display lights inside the cabinet.

The unit is now operating and the display will continually show the 

current interior cabinet temperature.  The night power switch on the 

front of the control box should be used to turn the unit off at night.  

This removes latent heat from the heated module preventing high limit 

lock out.  If desired, the main power switch can be turned to the off 

position once the fan has turned off. Approximately 3 minutes.

1.  Disconnect power.

2.  Disconnect power harness.

3.  Remove module from unit.

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 or discoloration.

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

Cleaning solutions need to be alkaline based or non-chloride cleaners.  
Any cleaner containing chlorides will damage the protective film of
