FIND WHATS WRONG

Johnson controls heat pumps have a muffler and a filter dryer in the condensing unit most of the time.

Ok. On the new split systems I can see how a hack would mistake the muffler as a filter.

I've done that myself "once" after a compressor change out. Anyways, i was back there fixing a restriction a few months later. Because with the dryer in backwards it doesn't filter squat. Just bypasses around the core.

this is a 5 year old system

The arrow Is supposed to point the correct way To the compressor - which it through the evaporator and the suction line. The one pictured here points the wrong way to the compressor. <g>

But I thought the arrow was to point the way to the compressor.

the arrow indicate the refrigerant flow, in this case from the condenser to the air handler.

I had a guy working for me who generally put driers in the discharge line. When eventually asked he told me it was only because the discharge lines were easier to get to.

I don't recall. Also don't know if they put it on the LL because they didn't know the difference between the liquid line and discharge line or if they replaced a discharge muffler with the drier because they didn't know what a muffler is.

You guys are all wrong - the arrow is supposed to point north.

Although maybe soon they will all have to be installed pointing to Mecca. <g>

There’s always the possibility the installer switched the sticker around to prank their coworker and didn’t switch it back. I did that once on the first solo ac I was sent on, little 1-1/2 ton unit, my boss told me he was going to look at it afterwards so I thought I’d pull a little prank on him, he never did end up looking at it...

My big question is..... which way do you point the arrows on a bi flow filter dryer?

That's easy, they point with the pipe if they are open and across the pipe if it is closed.








Oh wait, that a valve handle.

From now on the correct terminology is transgender drier

A few of old York heat pump had regular LL driers on the discharge lines just before reversing valve. I also seen some old carrier units with muffler on discharge lines that was just empty drier shell. I once removed a rusty muffler off an old round carrier unit and didn't notice change in compressor noise.
