Part number 20072, Rev 06NORMAL OPERATIONAfter the unit is properly installed and power is applied, it will take some time before thesystem is cooled down to temperature and cycling normally. You should wait 8 hours on thefirst startup before beginning to add product to the unit. This ensures that the unit is installedand 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 unitshould be cycling in the desired temperature band. The temperature control was calibratedbefore leaving the factory, so no adjustment should be necessary.Loading the units will again cause temperature to rise as the warmer product is introduced intothe compartment. If a large amount of product is to be introduced, it is a good idea to do it instages, allowing several hours between stages to allow temperature to stabilize again beforeintroducing additional warm product. This will minimize the temperature transient whileloading. 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 properair flow and, therefore, more even cooling of the product.- When loading the top shelf, avoid blocking the evaporator fan(s) (if installed). There shouldbe at least 4 inches of clearance below the fan(s) to allow proper air flow.- 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 forbest results.- Minimize the time the door is open. On top of letting the cold air out, you are also lettingwarm, 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 thefactory. We also do extensive testing to ensure that these temperatures will result in producttemperatures in the desired band. There should be no need to adjust the temperature controlon these units, but if it is necessary, they can be adjusted using the manual thermostat on theinside of the unit.It is STRONGLY RECOMMENDED that you contact the manufacturer’s Technical SupportDepartment prior to performing any temperature adjustments to ensure the adjustment isnecessary and, if so, it is performed correctly.
