Air conditioners are designed under specific operating conditions reflecting average use. The specification charts listed (data tag) with each model reflect that model's power consumption at these design temperatures only. Design temperatures for most Coleman®-Mach® RV air conditioners are 95° F. outdoor temperature, 80° F. indoor temperature and 50% relative humidity.
We are aware that the conditions under which our air conditioners might be operating may vary considerably from these design parameters. We do not size generators. However, to access information on sizing the units or amp draws, access our Document Library. In the Document Library, type your model number in the search engine and locate the data sheet.
To calculate the max potential startup: Find the running amp draw for your system and multiply it by 2.5. With this information, your generator manufacturer should be able to assist you in sizing a generator suitable for your application.
