♦ De-icers will create small localized currents the longer they run. Fewer and longer operation cycles will prove to be more effective than more frequent and shorter operating cycles.

♦ Daily observation is required for all de-icing installations. Adjust operating times based on when you can observe the operation. This will help you check the de-icer is operating properly.

♦ Mount the C-20 out of direct sun light. This will prevent excessive internal heating of the controller. Internal heating may prevent the C-20 from operating correctly.

♦ Operating with fewer, longer cycles will provide the most efficient de-icing. The following is an example of setting the timer over a 24 hour period. The 4 ON cycles below allow for more operating time during dark hours and less during daytime hours. (This is suggested due to increased freezing rate at night).
