NORMAL OPERATION

 

After  the  unit  is  properly  installed  and  power  is  applied,  it  will  take  some  time  before  the 
system  is  cooled  down  to  temperature  and  cycling  normally.  You  should  wait  8  hours  on  the 
first startup before beginning to add product to the unit. This ensures that the unit is installed 
and operating properly before being put into service. On subsequent startups (after cleanings, 
for example), this  wait time  can be  reduced  to about  3  hours.     After  this  wait time,  the unit 
should  be  cycling  in  the  desired  temperature  band.  The  temperature  control  was  calibrated 
before leaving the factory, so no adjustment should be necessary.  

Loading the units will again cause temperature to rise as the warmer product is introduced into 
the compartment. If a large amount of product is to be introduced, it is a good idea to do it in 
stages,  allowing  several  hours  between  stages  to  allow  temperature  to  stabilize  again  before 
introducing  additional  warm  product.  This  will  minimize  the  temperature  transient  while 
loading. Other tips for successful loading include:  

-

 

Leave about 2-3 inches of free space along the back and sides of the unit to allow for proper 
air flow and, therefore, more even cooling of the product.  

-

 

Do not overload the unit. Maximum suggested load is about 75% of the chamber capacity. 
Additionally, the load should be distributed evenly from top to bottom and side to side for 
best results.  

-

 

Minimize the time the door is open. On top of letting the cold air out, you are also letting 
warm, moist air in which can result in more condensation and/or frost in the unit.   

Remember  that  the  units  are  calibrated  to  the  desired  temperature  band  before  leaving  the 
factory. We also do extensive testing to ensure that these temperatures will result in product 
temperatures in the desired band. There should be no need to adjust the temperature control 
on these units, but if it is necessary, they can be adjusted using the manual thermostat on the 
inside of the unit

.  

It  is  STRONGLY  RECOMMENDED  that  you  contact  the  manufacturer’s  Technical  Support 
Department  prior  to  performing  any  temperature  adjustments  to  ensure  the  adjustment  is 
necessary and, if so, it is performed correctly.
