SAFETY CONSIDERATIONS
Recognize safety information. This is the safety-alert symbol

). When you see this symbol on the unit and in instruc-
tions or manuals, be alert to the potential for personal
injury.
Understand the signal words — DANGER, WARNING and
CAUTION. These words are used with the safety-alert sym-
bol. Danger identifies the most serious hazards which will
result in severe personal injury or death. Warnings, on the
other hand, could result in personal injury. Caution is used
to identify unsafe practices which would result in minor per-
sonal injury or product and property damage.
WARNING: Before performing service or mainte-
nance operations on unit, turn off main power switch
