To Manually Force A Defrost

1
To Manually Force A Defrost:
1. Open the drawer.
2. Press the LOCK button for 3 seconds to unlock the control panel.
3. Within 15 seconds, press and hold the LOCK button, then within 1 second press the WARMER
button. Hold for 3 seconds. The display module will beep a melody to indicate that defrost mode has
been entered.
Turning the power off to the CoolDrawer will abort the defrost and the appliance will return to normal
operation when the power supply is resumed.
Note: There will be a delay of 5 minutes before the element starts to heat after going into this mode. This is
known as evaporator warm up time. The defrost element then turns on and will remain on until any of the
sensors (defrost, evaporator inlet or evaporator outlet) have reached +8
defrost. The defrost sensor is located in the evaporator chassis above the evaporator.
After the defrost element has turned off, the defrost cycle enters what is known as drip time for a total of 10
minutes.
After the first 3 minutes of drip time the compressor will turn on. The evaporator fan remains off for a further
7 minutes before it restarts. (Refer to Section 10.3).
Note: A defrost will not occur if the defrost sensor is above +8
adapter plug and clip on-amp meter in the power lead will indicate whether or not the defrost element is
drawing current.
Note: A defrost cannot be manually forced while the cabinet is in the Bottle Chill mode.
