Drain the engine oil out of the sub oil pan and inside the engine
- Stop the engine by controlled shutdown before the maintenance. (refer to ‘Operation restriction
of the outdoor unit prior to maintenance’ in the ‘Self-diagnosis’)
- Remove the cap from the top of the oil tank and drain out the oil with an oil filter pump as
shown in the picture. Perform the same for the level sensing tank.
- Dispose of the waste oil into a waste oil container.
- Dispose of the waste oil from inside the engine into the waste oil container after removing a
hose on the bottom.
- Be sure to take a time to drain out the waste oil completely.
- If you operate the engine for about 15 minutes before the drainage in winter, it will make the
work easier. (be careful of the heated area)
