How do you service an evaporative air conditioner? It is straight forward, as long as you are happy getting on to your roof.

• Remove filters & wash with a hose,
• If you have an old system, pull out the sump dump to release the water from the tank,
• If you have a new system there will be no water because the dump valve clears the tank automatically,
• Wipe out the inside of the unit where the water tank is,
• Using a soft wire brush, lightly brush the motor & spray with CRC/WD40,
• If you have an old unit;
  • Replace three of the filters
  • Fire up the unit to check the motor & water pump are running as normal
  • Then release the water
  • Replace the fourth filter
• If you have a new unit, fire up the unit to check the motor & water pump are running as normal.
