They don't even ship them properly set. They expect that a trained technician is on site at start up. I generally use 4 defrosts in 24 hours at 30 - 45 minutes each. It depends on which timer is installed.

inside on the right side of the fan/coil housing. should be a black knob marked 1 - 9 the higher you set it the colder it will run. Normally set on 7 or right between 7 and 8.

Try defrosting the unit by shutting it down until all ice is gone. If this corrects the problem and the ice returns you may either have a defrosting problem or a low freon charge.

well most t stats have a differential of 5 to 7 but almost never more than ten deg so that the compressor wont short cycle .something you can check .some t stats you can adjust the differential on check if yours has that adjustment screw on the side or back of T stat if you need more help or parts e mail me at [email protected]

Let it run. Coil temperature has to be low enough for the fan delay switch to close.
