Tips and Troubleshooting
Before calling for service, check the following:
1. Check electrical power supply to the equipment for
connection.
2. Check fixture loading. Overstocking case will affect
its proper operation.
3. If frost is collecting on fixture and/or product, check
that Humidity Control is working properly, and that
no outside doors or windows are open - allowing
moisture to enter store.
