PARTS OF THE CONDENSING UNIT:

ANOTHER VIEW OF ANOTHER CONDENSER:

Notice that this condenser has some extra parts. It is a HEAT PUMP.
Heat pump condenser parts
Notice the following:
27,29,30...The reversing valve
28.........Defrost sensor
31.........Accumulator device to help keep refrigerant from "slugging" liquid into the compressor
32.........Muffler

Notice, also, that this design doesn't use a rain shield for the fan motor. The top cover of the unit has a solid metal center to assist in rejection of the water.

These motors can withstand quite a lot of water, but not a deluge. If the motor ends are built with air openings or if the grill cover holding it does't provide sufficient protection, then a rain shield must be installed to solve the problem.

Rain shields are plastic or metal and have a bored opening in the center for sliding it down on the shaft (if the motor shaft faces upward). Sometimes manufacturers will place a metal one above even a motor whose shaft is downward. Of course, if it is above a motor whose shaft is downward, then there is no hole bored for the shaft. The one in the picture is like that. So when you see a Rain Shield, you will know its purpose.
