Hoshizaki KM-900MRF3, KM-900MWF, KM-900MAF instruction

After the 1 minute ± 5 second water supply cycle and the 2 minute ± 10 second defrost cycle, the unit should start the freeze cycle.

(ii)After the above step (i), disconnect the Float Switch leads from the Controller Board within the first 5 minutes of the freeze cycle.

The unit should go into the defrost cycle after the first 5 minutes ± 20 seconds of the freeze cycle.

(iii)Reconnect the Float Switch Connector to the Controller Board. After the first 5 minutes of the freeze cycle, disconnect the Float Switch leads from the Controller Board.

At this point, the unit should start the defrost cycle.

(iv)After Step (iii), de-energize the unit and confirm that the Defrost Timer is in the minimum position. Disconnect the resistor from the Controller Board, and ener- gize the unit.

After the 1 minute water supply cycle, the defrost cycle starts.

Re-connect a 1.5 kΩ - 3.5 kΩ resistor to the Connector K3 (pins #1 and #2) after the first 2 minutes of the defrost cycle.

The unit should start the freeze cycle after 1 minute ± 5 seconds from the resistor connection.

3) Check the Controller Board by using test program of the Controller Board.

The Output Test Switch “S3” provides a relay sequence test. With power OFF, place S3 on and switch power to ICE. The correct lighting sequence should be none, 2, 3, 4, 1, and 4, normal sequence every 5 seconds. S3 should remain in the “OFF” position for normal operation.
