The factory instructions have a diagram that show where you wiring goes to.
The diagram will have Line/Feed & Load wiring
Line or feed = 120v INCOMMING power
Load = Outgoing power or aka Powerstrip there will also be a set of manual swithces or pin swithces on the left side facing the unit you will have to filp or at best dbl check mine was set in cooling mode they heat and cool stat wise.
If you have a problem ill dig my unit out from behind the cages and remove the cover and take a picture of it.
are you buying this from a place like Grainger or HVAC supply ?
if so i know around here thr Johnsons run about $44 or so each if you are you might ask a counter person they should be able to show you well maybe and JC also has a tech line you can call they are veryyy helpful in helping you set them up and talking you through the functions over the phone. Whenever i have anyone ask it sounds bad but calling them is the BEST way to get solid understandable answers they make them who can answer anything better the the maker right ? lol
but if you want a pic email me i think you have it and ill take off the cover
goodluck
