11. Care and Maintenance

To ensure maximum performance of your water heater and to reduce the risk of a water leak, we recommend the
following maintenance:
• The water heater has minimally required maintenance procedures. Periodic inspections and tests are always
recommended for signs of damage or failure. Any damage, cracks, leakage or weakness should be addressed
and fixed immediately. Do not over tighten any of the connections. Over tightening the connection points could
cause severe internal damage to the unit.
• Remember that water heated at higher temperatures produces scale buildup much faster than at lower
temperatures. Having manual shut-off/maintenance valves installed on the inlet and outlet of the water heater
will allow access to flush the unit with a descaling solution. We recommend routine maintenance once a year or
once every six months if the water supply has an unusually high level of mineralization (hard water)
• Clean the pre-filter on the inlet water side once every six months. Wash lightly to remove any debris.
When any form of maintenance is carried out on the water heater or the home's plumbing system that may introduce
air into the plumbing pipes, it is crucial to power off the water heater and purge the air out of the lines before allowing
the unit to power up.
FAILURE TO DO SO COULD RESULT IN PERMANENT DAMAGE TO THE HEATING ELEMENT AND VOID YOUR
WARRANTY.
When air is introduced into the plumbing system, follow the steps below to ensure the unit can safely resume operation.
1. Shut off all power connections to the unit at the circuit breaker on the main electrical panel.
2. Perform the maintenance or servicing tasks.
3. Open one or more hot water faucets and allow water to run through the unit for several minutes to purge any air
from the heater and water lines.
This step must be performed before turning on power to the heater. Failure to complete this step may
cause permanent damage to the heating elements.
4. Reconnect power to the unit at the circuit breaker on the main electrical panel. Press and switch the ON position.
5. With the water running through the unit, check and reset the temperature if necessary. The recommended
temperature setting is 118°F (48°C).
