If the Bradley Electric Tankless Water Heater is stored in an outdoor environment, care should be taken to protect the
heaters from:
• Rain or other falling precipitation via tarp or other waterproof media .
• Runoff and accumulation of groundwater from any source that may exceed 1 inch (25 mm) .
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, the heater must be drained of water. Freezing of the heater can
cause serious damage. Follow notes in Start Up Check List section following electrical lockout/
tagout procedure.
