This freezer is designed for automatic defrost. Every eight hours the refrigeration system is turned OFF and
the defrost/drain heaters are activated to melt the ice from the evaporator coil and drain pan. If the freezer
is not leveled properly, the water may not drain out of the freezer, it will re-freeze and ice gradually builds
up. Excessive ice buildup reduces cooling performance and may cause the failure of refrigeration system
and product loss. Ice buildup may be noticed through the evaporator fan grill on the coil fins.
To perform a manual defrost, follow these steps:
1. Press the UP arrow button and hold it for 6 seconds.
2. Wait until the electronic control stops defrost (the Def LED dot flashes)
3. If ice is still noticeable on the evaporator, press the freezer switch to the “Off” position then
disconnect the freezer from the power supply.
4. Take down the evaporator shroud and use a hair dryer to quickly melt the ice.
5. Make sure the freezer is leveled side to side, and front to back or slightly tilted front to back.
6. Replace the evaporator shroud.
