Installation Manual
Snow Melting Control PM-653
Installation must be performed by qualified persons, in accordance with local codes, ANSI/NFPA 70 (NEC Article 426) and CEC Part 1 Section 62 where applicable. Prior to installation, please consult the local codes in order to understand what is acceptable. To the extent this information is not consistent with local codes, the local codes should be followed. However, electrical wiring is required from a circuit breaker or other electrical circuit to the control. It is recommended that an electrician perform these installation steps. Please be aware local codes may require this product and/or the control to be installed by an electrician.
