It’s really important you read these warnings and this entire
installation guide before you get started. And please follow
each step exactly as its shown:
General Installation Warnings & Cautions Electrical Warnings & Cautions
● Follow all warnings and safety instructions.
● To avoid risk of personal injury, property damage, and product damage,
pay close attention to the following during installation:
○ The AC could fall if it is not properly installed, which could result
in death or serious injury. Pay close attention to steps 2 and 3 to
ensure you properly position and secure the AC in the window.
○ The Windmill AC is heavy. Two or more people are needed to move
and install the unit. We don’t want you hurting yourself, so please use
proper carrying and lifting techniques (as they say, lift with your legs,
not your back!).
○ Do not touch the metal ns or the front and rear coils - they’re sharp.
Wear protective gloves whenever lifting or carrying the unit and
handle the AC with care.
○ Carefully inspect the window where you are installing your AC unit.
Make sure it is in good condition and can support the weight of the
unit over a long period of time.
○ To make sure the AC doesn’t fall out of the window during
installation, use a helper to securely hold the back of the unit up
while positioning it properly in the window.
● Use only the screws that are specied in this guide.
● To avoid injury, wear closed toe shoes and do not wear loose clothing that
could get tangled in the unit during installation.
● Save these instructions for future reference or visit windmillair.com/
support.
● The AC must be properly grounded to avoid a re or electrocution
hazard. You must use a grounded three-prong outlet. Do not remove,
cut, or bypass the grounding prong on the plug. DO NOT use an
extension cord, surge protector, or multi-outlet adapter with this
window AC.
● Observe all local, state, and national electrical codes and only use
qualied, licensed, and authorized personnel for electrical assistance.
Seek professional help if there is any doubt with your outlet or plug. If you
do not have a three-prong outlet, call a licensed electrician to make any
required changes to your outlets.
● Power cord may include a current interrupter device. TEST & RESET
buttons are included on the plug case. You should test the device
periodically by rst pressing the TEST button and then pressing the RESET
button. If the TEST button doesn’t trip or if the RESET button doesn’t stay
engaged, stop use of the AC and contact Windmill at windmillair.com/
support.
● Do not turn off the AC by pulling the electric cord or using the current
interrupter device as an on/off switch.
● DO NOT push the TEST button while the unit is running (this can
damage the plug).
● The conductors inside the cord are surrounded by shields, which monitor
leakage current. They’re not grounded. Periodically examine the cord for
damage, and don’t use the AC if the shields are exposed.
● Electrical parts can cause shock or re. Do not open the tamper-resistant,
sealed portion of any electrical components. Do not attempt to replace
the power cord or repair any electrical components. If the power cord is
damaged contact Windmill at windmillair.com/support.
● Improper installation or servicing and intentional damage will void the
Limited Warranty.
