Recommended storage criteria:
Store Keltech Electric Tankless Water Heaters where temperatures exceed 35ºF (2º C) at all times .

NOTICE! For heaters with ENHT freeze protection option: If the heater is stored where the temperature
could fall below 45°F(7°C), the heater must be powered immediately after hydro testing to insure
internal freeze protection components are activated. Once the heater is installed and the on-site
plumbing has been hydro tested, the power supply must remain constant until the risk of freeze is
eliminated. If this is not possible, do not allow the heater to remain full of water. The heater must
be drained. Freezing of the heater can cause serious damage. Follow notes in Start Up Check List
