I am framing in a couple of holes in the ceiling of my MC-9 for rooftop a/c units. I have a couple of questions. First, should I make the holes exactly 14x14, or should I open them up a little? Second, where should my 120 volt wiring enter the opening - on the side of the hole facing the front of the coach? The side facing the rear? Driver's side? Passenger side? Does it matter?
Thanks for the help... MR |

14" x 14" is fine, leave some extra wire (20" or so), once the unit is installed you can cut off what you do not need, I entered the hole from the driver side but it does not madder....wire is cheap leave enough.... |

I found that 14.25" x 14.25" worked well for AC and skylights. That gives 1/8" fudge room on each edge. I can't address the cord thing as my wiring is still extension cords zip tied to the ribs . . .

Don't think the direction the wiring comes from matters. I brought mine in from the right side. If in doubt, you can ask someone at Camping World or the like for the unit you are interested in. |

I just put on a MACH 3 PS last weekend.
Facing the front of the unit where the controls are, the wiring was on the left. |

14X14 is the rite measurement and as far as the wiring goes from the side if you are ducting it ive installed many roof units they go on easyly |

If you have bought the heating element, you might want to add a thermostat to control the temp. Earlier threads indicate that they are not good to be a full time heat supplier but when they are on, they are on all the time, so if you used it to keep toasty warm over night, you might get too warm. The addition of an electronic relay to switch the 110v feed to the heater element and 12vdc thermostat would do quite nicely for comfort levels. If you really like to play with wires, you can get an heat/cool thermostat and use another electronic relay to control a small 110v vent fan in the ceiling or side, when it gets too cool inside at night, it would switch off the fan keeping the coach comfortable.
This is just something I found worked quite well for my needs. You would find that most of the time you would use the heater element, unless of course, you like weather climates like the frozen wastelands of the North in sub zero temps, then use your furnace. - just my thought - q |
