From the Manufacturer

Chronomite was the first to patent a microprocessor technology which allows for a pre-set or controlled output temperature that delivers unlimited hot water without risk of scalding-in two seconds as opposed to the six seconds offered by other tankless water heaters. Chronomite is installed at point of use and is only operational when hot water is requested, thus dramatically reducing hot water delivery time and inefficient use of electricity.

For optimal performance, Chronomite electric tankless water heaters should always be installed within 18 inches from the point of use.

Chronomite Tankless Water Heaters are U.L. listed. The U.L. listing requires that the heater be "hardwired" to a dedicated breaker. To gain optimum performance and to keep the product under warranty, it must be installed in this manner. Please refer to our Installation and Operation sheet for the model you are installing.

Confirm that the heater has been hardwired to a dedicated, non-GFI breaker. Also check that the breaker size is appropriate for the heater being installed (Example: if it is a 30 amp heater, it will need a 30 amp breaker)
