IMPORTANT SAFETY FEATURE
Power Cord With Integral Safety Protection
All PTACs rated 250
V or less that are cord connected
to the power supply are equipped with a power cord
with integral safety protection as standard. Providing
personal shock protection as well as arcing and
fire prevention, the device is designed to sense
any damage in the line cord and disconnect power
before a fire can occur. Tested in accordance with
Underwriters Laboratories, the cord set also offers a
unique “passive” operation, meaning the unit does not
require resetting if main power is interrupted.
WARNING - A DAMAGED POWER SUPPLY CORD
MUST BE REPLACED WITH A NEW CORD FROM
THE MANUFACTURER, AND NOT REPAIRED.
Each power cord should be checked before every
use. Follow the instructions in the order listed on the
device.
WARNING - DO NOT USE THE PRODUCT IF THE
UNIT FAILS THE TEST.
MODIFICATION AND TAMPERING
Note: Unit uses R22 refrigerant.
