Sanyo MDF-U5486SC Setting Of Compressor Delay Time, Description of operation, Key operated

SETTING OF COMPRESSOR DELAY TIME

The delay time of high and low stage side compressor can be changed to reduce the load on the power line and to facilitate the start-up (reset) of the freezer after power failure.

The example in the table is based on the assumption that the delay time is changed to 4 minutes. (The delay time is set in 3 minutes at the factory.)

Note:

•The setting range for delay time is between 3 and 15 minutes. The cool down of chamber temperature may be slow when the setting of delay time is over 5 minutes, depending on the installation environment. There is no need of changing the delay time when the capacity of power source is adequate.

•The compressor starts to operate with the delay time set by the above procedure at the time of power on or after power failure. However, the start up of the low stage side compressor is affected by the chamber temperature and the cascade condenser temperature. The delay time varies depending on how they meet the start up conditions.

•The set mode returns to the temperature display mode automatically when 90 seconds has passed without any key operation. In this case, any setting before pressing set key (SET) is not memorized.
