I have a 20+ year old Chrysler AC condensing unit, model 1204-02, probably 36,000 Btu/hr.
This has a rectangular housing, sits directly on a slab, no space beneath. The fan blade is at the top of the unit, above the coils. The fan/motor shaft is vertical, so the fan rotates in a horizontal plane.
The two coils are below the plane of the fan, each coil assembly is parallel to and against one side of the unit, with the unit's side being made of expanded metal to allow air flow.
Which way should the air flow through the condensing unit? In at the top, through the fan, and out horizontally through the coils and grills on the sides? Or vice versa?
Thanks in advance.....Michael
