SAFETY CONSIDERATIONS
IMPORTANT: Air-handling equipment will provide safe
and reliable service when operated within design specifica-
tions. The equipment should be operated and serviced only
by authorized personnel who have a thorough knowledge of
system operation, safety devices, and emergency proce-
dures. Good judgment should be used in applying any man-
ufacturer's instructions to avoid injury to personnel or
damage to equipment and property.
Disconnect all power to the unit before performing mainte-
nance or service. Unit may automatically start if power is not
disconnected. Electrical shock and personal injury could result.
If it is necessary to remove and dispose of mercury contactors
in electric heat section, follow all local, state, and federal
laws regarding disposal of equipment containing hazardous
materials.
See Fig. 1 for the Proposition 65 warning label.
