Had one just like it here. Condo complex. Someone set their new Jani#$!@ on the old HS-6 just like here. Later we changed them to an add on HP. Tried setting it on top of the Jani but it was hard to reach for service so we took them both out and used a pad & pump ups
That's called recycling. When you have to replace your system, you just use the old condensor for a pad. Especially in areas where there is high snow levels, and you are installing a Heat Pump. That way it keeps the condensor above snow level.
