All - For those who have oasis hydronic heating system, I found a great video on how to do a service it's here -
- Now with that said.
Current coach has HHot Unit, was not installed to AQ/HH recommended specs, not that it is unsafe, just not easy to service.
The above video, although on a test bench arrangment, does not look to difficult to service, much simpler than a comparable HH system it appears.
Happy Tails to You.
