L1, L2 and ground should connect where circled.
Be sure to use the proper sized copper wiring.

Thank you for the reply but my Air Handler don't have the PLF or the PLM like on the diagram where it show the L1 and L2.Can I just plug into the Transformer where it show 1 and 3.Thank you

There should be a very specific place to connect the line wiring.
Do you have one large line to feed the air handler and heat strip or two separate circuits ?
Post a pic or two of the air handler wiring area.

the only thing that i have is a braker for the heat strip.I connect the power there and the air handler when you turn the thermostat to cool the air handler don't start,the outside unit will go on but not the airhandler,another thing is you turn the heat on you can smell the heat coming from the airhandler but the blower is not coming on.This whole unit is brand new.The transformer has some female plug that are cover by plastic with no wire going into then,that is why that I ask that maybe that is where the power will go.If you follow on the diagram from L1 and L2 that is where is showing that they go.

Sorry..... I'm going to need pictures. Every air handler I've installed has lugs for the incoming power line.

Since the electric heat kit is field installed, it sounds like you haven't connected the air handler to the heat kit via the plugs shown below. You may have to remove a plug/cap from the air handler side. PLM and PLF are just the nomenclature for male plug and female plug respectively. They do not look like what's shown in the wiring diagram. You should be ok if you have 230 volts at the circuit breaker on the heat kit. Hope it is as simple as that.

Can someone please help.It has been more than a week and still don't know where the power go. You can see on the picture of the airhandler where I have the power connected to the heat strip braker.I also post some of the pictures of thermostat on how I have it wire.Can somebody take a look and tell me is the wires are on the right place.Thank you

The aux heat wire is in the wrong spot. Should be jumped to E.
What’s the yellow wire nut with the red wires?
Who’s going to do system start up and charging? Maybe they can assist you with the wiring.

the yellow wire nut with the red wire.I'm the one that did that it is the only way that I can get the blower in the airhandler to work that is the way that I'm supplying power to the transformer it is going to leg 1 and 3 leg wish it is on the diagram showing for 240 volts.it runs like that.I was just testing but I know that is not the way that it should stay.Thanks for your reply and help

Where is the factory plug that gets removed when you install electric heat? You remove that and it gets connected to the electric heat pack.

You attached your incoming supply wires to the top of the breaker. That looks correct.
What is the amperage on that breaker ?
It looks like that air handler requires two circuits. One for the strips and one for the blower.
Can you post a tight picture of just the breaker and contactor.

I was looking at the installation manual. I think this is the right diagram. It looks like your two black wires from the heat strip go to the breaker as well as the red and black ones that feed the air handler.

Right now if I feed the transformer with the black on leg 1 and the red on leg 3 it works fine(leg transformer is 208 volt not used)I just not sure if that is the way that can state.I think that the heating strip braker is 50 Amp.I can run an extra breker for the transformer not sure that that is the way but it does work that way.Thank you for all the help.The Diagram wires look good

No, that’s incorrect. It’s a split system, the refrigeration work is done in the field.
Take a picture showing the entire air handler.
I hope you didn’t connect the lines and open the valves.......you’ll destroy the unit.

Sorry for the late reply.I had a friend that finish charging the system,if i'm not mistaking i think he also used a vacuum pump before he open the line.Thank you for the advise.

I certainly hope he knew what he was doing.
And with no blower running, he couldn’t have finalize the charge.
