Sanyo MDF-C8V service manual Change of Compressor Delay Time

Page 54

CHANGE OF COMPRESSOR DELAY TIME

The delay time of the 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 2 minutes at the factory.

Note:

ŶThe setting range for delay time is between 2 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.
