INVERTER INFORMATION
Important Information About Your New Whistler
Inverter.
This manual will provide you with directions for the safe
and efficient operation of your Whistle Power Inverter.
Important Note: Each of the following operating
procedures and safety features must be carefully reviewed
and thoroughly understood prior to using the inverter.
Failure to do so may result in damage to the inverter or
equipment or serious personal injury.
Notes:
Your Whistler inverter is designed to operate from a 12 volt
power source only. Never attempt to connect your
Whistler inverter to any other power source, including any
AC power source.
•110 volts can be lethal. Improper use of your
Whistler inverter may result in property
damage, personal injury or loss of life.
•Check with the appliance manufacturer for com-
patibility with modified sine wave inverters. Some
appliances may not work well, not at all or be dam-
aged.
This is especially true for medical equipment.

Getting Started
Powerequipmentandappliances which operatewithmotors
or tubes requirean initial surge of power to get themup and
running. This power surge is referred to as the "starting
load" or "peak load." (By comparison, electrical devices
such as standard light bulbs do not require a large starting
load). Once the equipment or appliance hasbeen powered
up,it settles downtoaslowerpaceandrequiresfar lesselec-
trical power to operate. This lower power requirement is
referred to as the "continuous load."
In order to ensure that the capacity of your Whistler inverter
is sufficient to meet the required start up load, you must first
determine the power consumption of the equipment or
appliance you plan to operate.
Power consumption isratedeither in wattage or in amperes,
and information regarding the required "watts" or "amps"
generally is stamped or printed on most appliances and
equipment. If this information isnot indicated on the appli-
ance or equipment, check the owner’s manual. Contact the
appliance or equipment manufacturer to determine if
the device you are using (TV’s, battery re-charger, com-
puter, etc.) is compatible with a modified sine wave.
If the power consumption is rated in amps, multiply the
number ofamps by110 (AC voltage) to determine the com-
parable wattage rating. As a general rule, you can deter-
mine the required start up load by multiplying the wattage
rating by 10.

ciples of Whistler inverters and related technical data, see
