Warnings

Warnings are posted throughout the manual. These warnings are designated
by an exclamation mark inside an equilateral triangle and text highlighted in
bold. Read and follow these important instructions. Failure to observe these
instructions can result in permanent damage to the unit, significant property
damage, or personal injury or death.
The lightning flash with arrow symbol, within an equilateral triangle, is intended
to alert the user to the presence of non-insulated "dangerous voltage" within
the unit's enclosure. The voltage may be of significant magnitude to constitute
a risk of electrical shock.
This label, engraved into the front of the tank lip, indicates the presence of hot
surfaces.
Make sure you read and understand all instructions and safety precautions
listed in this manual before installing or operating your unit. If you have any
questions concerning the operation of your unit or the information in this
manual, contact our Sales Department.
