It runs lateral in-roof ducting with side air discharge, wires to a standard wall thermostat, and ships with the control box and mounting hardware you need to drop it in.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you're servicing or replacing a ducted Coleman Mach rooftop air conditioner, the 8430A633 is the interior piece that makes the whole system work. It's the ducted ceiling assembly, the part that mounts to your RV's ceiling under the rooftop unit and hands off cooled air to the ducts running through your roof. The rooftop unit does the cooling. This assembly is what actually distributes it through the coach.\u003c\/p\u003e\n\u003cp\u003eThis one is the cool-only version in white. No heat strip, no heat-pump wiring. If your rig cools from the roof and heats from a furnace, that's exactly what it's built for. Adding electric heat later means a different ceiling assembly, so match the part to how your system is set up before you order.\u003c\/p\u003e\n\u003cp\u003eThe ducting here is lateral in-roof, with side air discharge. That means conditioned air leaves the assembly out the sides and into the ductwork buried in your roof, then feeds the registers down the length of the coach. It's the layout you'll find on most ducted travel trailers and fifth wheels, where you want air spread evenly from front to back instead of dumped straight down out of one grille. Side discharge keeps the airflow moving into the duct runs rather than fighting the ceiling. On a longer coach, keeping those duct runs clear and sealed is what gives you cold air at the far registers, not just the ones nearest the unit.\u003c\/p\u003e\n\u003cp\u003eControl-wise, this assembly is set up for a wall thermostat. The control box uses a 12-volt control circuit to switch the 120-volt power that runs the rooftop compressor and fan. In plain terms, your wall thermostat sends a low-voltage signal, the relays in the control box close, and the rooftop unit kicks on. It's a clean, reliable way to run a ducted system, and it's why you get even cooling you set from a thermostat on the wall instead of a dial buried in the ceiling.\u003c\/p\u003e\n\u003cp\u003eEverything you need to get it mounted comes in the box. You get the control box and the mounting hardware, so you're not chasing down brackets or fasteners partway through the job. The assembly seats against the ceiling opening, ties into your existing ducting, and wires to the rooftop unit and thermostat. If you've pulled a rooftop A\/C before, this is a familiar job. If you haven't, it's still a manageable afternoon with the Coleman Mach install instructions in hand.\u003c\/p\u003e\n\u003cp\u003eWho's this for? RV owners running a ducted Coleman Mach system that need to replace a cracked, aged, or failed ceiling assembly, and installers building out a ducted setup on a new or refit coach. If your air conditioner blows through a single ceiling grille with the thermostat built into it, you've got a non-ducted setup and this isn't the right part. This assembly is specifically for ducted rigs running a wall thermostat.\u003c\/p\u003e\n\u003cp\u003eA few things worth checking before you buy. Confirm your system is cool-only and not a heat pump, since this assembly is wired for cooling only. Confirm you're running a wall thermostat, not a ceiling-mounted control. And confirm your Mach unit is a ducted model feeding lateral in-roof ducting. Get those three right and the 8430A633 drops in as a direct fit. Get one wrong and you'll be looking at a different assembly in the Coleman Mach lineup.\u003c\/p\u003e\n\u003cp\u003eIt's white, so it blends into most RV ceilings without standing out. And because it's genuine Coleman Mach hardware, it matches the fit and finish of the rest of your system. When you're putting the ceiling back together after a repair, that consistency matters. You don't want a mismatched grille staring back at you every time you look up.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eCool-only ducted ceiling assembly for Coleman Mach rooftop air conditioners, distributes cooled air through your rig's in-roof ductwork\u003c\/li\u003e\n  \u003cli\u003eLateral in-roof ducting with side air discharge feeds registers evenly from front to back instead of dumping air out one grille\u003c\/li\u003e\n  \u003cli\u003e12-volt control circuit switches the 120-volt rooftop unit through the included control box for reliable thermostat control\u003c\/li\u003e\n  \u003cli\u003eWired for a standard wall thermostat, so you set and read cabin temperature from the wall, not the ceiling\u003c\/li\u003e\n  \u003cli\u003eControl box and mounting hardware included, everything needed to seat the assembly and tie into existing ducting\u003c\/li\u003e\n  \u003cli\u003eWhite finish blends into standard RV ceilings for a clean look after a repair or refit\u003c\/li\u003e\n  \u003cli\u003eGenuine Coleman Mach part number 8430A633 for a direct fit and matched finish with the rest of your system\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Coleman reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eDoes the 8430A633 include the rooftop air conditioner?\u003c\/summary\u003e\n    \u003cp\u003eNo. This is the interior ceiling assembly only, the part that distributes cooled air into your ducting.
