The controller will determine the temperature to be maintained during the hold phase based on the chilling cycle that has been completed. If a soft or hard chill has taken place the controller will maintain an air temperature of 2°c. The hold mode is principally intended as a temporary storage facility offering the operator flexibility until the product can be unloaded into a longer term storage units at the correct storage temperature. On occasion this hold period may become extended to ope

Blast Chill & Shock Freeze Operating Instructions. Standard Operation When mains electrical power is first applied to the controller it will carry out a self-test function, for approximately 3 seconds. During this period the display will show. On completion of the self test, the controller will revert to the last chill program that was run (Pre-chill, Soft Chill, Hard Chill, Hard Chill Max, Shock Freeze, Professional 1, Professional 2, or Professional 3).

Pre Chill This program is used to Pre Chill the cabinet prior to the first cycle. This is done with the Blast Chiller empty and is a short time based program of about 20 minutes. It is generally recognised as the correct method of preparing for a blast chill cycle. The program is selected by rotating the dial until the display shows, press and release the dial to start the program. Defrost. Defrosting is not normally required but if there is an ice build up on the coil inside

High Temperature: This alarm will only occur in the hold mode only. Probe the product to determine it is at the correct temperature. If it is at the correct temperature place in a storage refrigerator or freezer and call your Foster Authorised Service Company. If the product temperature is above the guidelines check the chill time selected or the weight of product being chilled does not exceed the specification for the Cabinet.

Foot Print Test operation The foot print test is a method of checking the operation of the process in a reduced time period The foot print test takes ten minutes. The first ten seconds are used for the display test, after that the relays are energised in a simple operating pattern to ensure each are energised. During the final ten seconds the alarm is sounded to indicate the end of the test. The graph below shows how the relays are energised relating to time. The air, coil and food temper
