Air Conditioning Operation
Bring the generator to a normal operating temperature before applying the air conditioning load. Always allow a two-minute wait period when manually cycling an air conditioner off and on.
A longer wait period may be required under unusually hot weather conditions. All other loads should be turned off until the air conditioner has started and is performing normally.
Before applying an air conditioning load, ensure that your generator is rated to handle to the load. Use the table below and the formula included in the AC Operation chapter for reference.
AC Output | Running (Rated) Watts | Additional Starting (Surge) Watts |
---|---|---|
Window AC - 10,000 BTU | 1200 | 3600 |
Window AC - 12,000 BTU | 3250 | 9750 |
Central AC - 10,000 BTU | 1500 | 4500 |
Central AC - 24,000 BTU | 3800 | 11400 |
Central AC - 40,000 BTU | 6000 | 18000 |
Follow the air conditioner manufacturer's instructions for starting and restarting for proper operation. Some air conditioner manufacturers offer a start capacitor as an extra cost option.
The lack of a start capacitor can cause the air conditioner to draw too high a starting current and overload the generator. Contact your air conditioner dealer if you consistently have problems starting your air conditioner with the generator.
