WARNING CAUTION
This symbol indicates the possibility of
property damage or serious consequences.
Installation must be performed according to the installation instructions. Improper installation
can cause water leakage, electrical shock, or fire.
Use only the included accessories and parts, and specified tools for the installation. Using non-
standard parts can cause water leakage, electrical shock, fire, and injury or property damage.
Make sure that the outlet you are using is grounded and has the appropriate voltage.
The power cord is equipped with a three-prong grounding plug to protect against shock.
Voltage information can be found on the nameplate of the unit.
Your unit must be used in a properly grounded wall receptacle. If the wall receptacle you
intend to use is not adequately grounded or protected by a time delay fuse or circuit breaker
(the fuse or circuit breaker needed is determined by the maximum current of the unit. The
maximum current is indicated on the nameplate located on unit), have a qualified electrician
install the proper receptacle.
