Your Evo 270 will operate most efficiently if regularly inspected as part of your home maintenance schedule.

MINOR ANNUAL MAINTENANCE

It is recommended that the minor maintenance be performed every 12 months by the dwelling occupant.

The minor maintenance includes:

  • Operate the easing lever on the temperature pressure relief valve. It is very important you raise and lower the lever gently. Exercise care to avoid any splashing of water, as water discharged from the drain line will be hot. Stand clear of the drain lines point of discharge when operating the valve’s lever.
  • Operate the easing level on the expansion control valve (if fitted). It is very important you raise and lower the lever gently.
  • Conduct a visual inspection of all plumbing and electrical connections.
  • Check the condensate drain line to ensure it is not blocked.
  • Check that air vents are not blocked or obstructed, and if necessary clean with a damp cloth or air blower.
  • Conduct a general external clean of the unit with a damp cloth.

MAJOR 5-YEAR SERVICE

It is recommended a major five (5) year service be conducted on the Evo 270.

Warning: Servicing of a water heater must only be carried out by qualified EvoHeat personnel. Phone EvoHeat Service on 1300 859 933 for our closest Accredited Service Agent.

Note: The five-year service and routine replacement of any components such as the anode and relief valve(s) are not included in the EvoHeat warranty. Only genuine replacement parts should be used on this water heater.

The major service includes the following actions:

  • Replace the temperature limiting valve.
  • Replace the temperature pressure relief valve.
  • Inspect the anode and if required, replace the anode. If the anode is not replaced, it should be replaced within three years of this service.
  • Check the heating cycle of the unit.
  • Visually check the unit for any potential problems.
  • Inspect the plumbing and electrical all connections.
  • Check the condensate on drain line to ensure it is not blocked.

Note: The water heater may need to be drained during this service. After the completion of the service, the water heater will take some time to reheat the water. Depending upon the power supply connect on, hot water may not be available until the next day.
