15,000 btu ac wattage

I am having a hard time finding my model # to seek exact literature on my AC. No manual came with camper either. Anyone know how many watts the Coleman Mach 15,000 btu AC uses? Only thing I could find online was for the heat pump version.

Thanks!

You will need to take the cover off the top and look for a sticker with the Model and Serial number. The sticker will have all the info your looking for. If you need the owners manual you can get it from; https://www.airxcel.com/rv/coleman-m...r-conditioners. I'm not sure if you need the serial number, too.


It will look like the picture below for my Coleman Mach 3 13.5k btu air conditioner.

Just to add a few pieces of info I've picked up recently by following several info sources. Based on Scarpper's pic, there are several important numbers:
  1. RLA - Rated Load Amps. This is the amperage usage once the AC unit is running. It will draw this load until it shuts down. For RV AC units it is probably 13-15 amps.
  2. FLA - Full Load Amps. This is the draw when a motor is running at max speed (fan on high).
  3. LRA - Lock Rotor Amps. This is the amperage draw that gets the rotor in a motor spinning from a full stop. Most of the time you can ignore LRA because this load only persists for 2-3 Milli-seconds. If you are on shore power it's not important. However if you are trying to run your AC on a generator, it becomes critical. It isn't unusual for an AC unit to have a LRA of >45 amps. A 2k or 2200 watt inverter generator is almost guaranteed to drop out if it sees this level of demand.
Mike Sokol just posted a blog talking about Easy Start units being installed on RV AC units to allow use of the smaller generators, it's worth reading.
