P3 International Kill A Watt P4400 Operation Manual

Tips for Using the Kill-a-Watt Device
READ THE INSTRUCTIONS
The Kill-a-Watt cannot be used to measure Direct Current appliances, such as hot tubs, ceiling fans, and
whole-house air conditioners. Only use it on Alternate Current appliances such as refrigerators,
televisions and computers (see enclosed tracking sheet for many more examples).
When measuring portable heaters, only measure using the low and medium settings. Using the Kill-a-
Watt on the high setting might break the device.
For large appliances, consider using a small extension cord to make the appliance-device-socket
connection. This is not required, but will make it easier to read the Kill-a-Watt screen.
If you suspect an appliance might be impacted by location (i.e., a refrigerator in line with a window),
then measure it on sunny and cloudy days for comparison.
To determine if your refrigerator or freezer has sufficient airflow, measure the power consumption
before and after clearing items off of the top of the appliance or pulling it out from the wall slightly. If
the power consumption drops after the clearing/pulling out, this indicates that it performs better with
less blockage.
Record your data on the included sheet, then enter it into the Excel spreadsheet provided on the
enclosed CD (you will need to save the Excel file to your own computer first). The equations to
determine annual usage are already programmed into the spreadsheet, though you will also need to
enter the rate per kilowatt hour as shown on your most recent electric bill. Entering the data is
completely optional, but doing so will help you determine how much each appliance costs you to
operate on a monthly basis.
When you return the Kill-a-Watt to the Library, please include this laminated sheet, the CD and the
instruction packet. The hard copy of the spreadsheet is yours to keep.
The City of Wheaton is able to make these devices available to residents free of charge thanks to the
Energy Efficiency and Conservation Block Grant issued by the U.S. Department of Energy, funded by the
American Recovery and Reinvestment Act.
