REFRIGERATOR 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 about 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 units are 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.
-
When loading the top shelf, avoid blocking the evaporator fan(s). There should be at least 4
inches of clearance below the fan(s) to allow proper air flow.
-
Do not overload the unit. Maximum recommended load is about 75% of the chamber
volume. 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.
This unit comes with a pre-drilled hole in the back wall for an additional temperature probe.
Look on the interior or exterior back wall for a small white plug with a sticker that says
“REMOVE PLUG FOR INDEPENDENT MONITOR PROBE INSTALLATION”.
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 per the “TempTech-2000 Electronic
Temperature Control” section of this manual
.
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.
