HAZARDOUS VOLTAGE!
Disconnect all electrical power, including remote disconnects
before installing or servicing. Follow proper lockout/tagout
procedures to ensure the power can not be inadvertently
energized. Failure to disconnect power before servicing could
result in death or serious injury.
CAUTION
CORROSION HAZARD! To prevent shortening its service life,
the air handler should not be used during the finishing phases
of construction. The low return air temperatures can lead to
the formation of condensate. Condensate in the presence of
chlorides and fluorides from paint, varnish, stains, adhesives,
cleaning compounds, and cement creates a corrosive
condition which may cause rapid deterioration of the cabinet
and internal components.
CAUTION
SAFETY HAZARD! Sharp Edge Hazard. Be careful of sharp
edges on equipment or any cuts made on sheet metal while
installing or servicing. Personal injury may result.
LIVE ELECTRICAL COMPONENTS! During installation,
testing, servicing, and troubleshooting of this product, it may
be necessary to work with live electrical components. Failure
to follow all electrical safety precautions when exposed to live
electrical components could result in death or serious injury.
EXPLOSION HAZARD!
Do not store corrosive or combustible materials, gasoline, or
other flammable vapors or liquids near the unit. Failure to
follow this warning could result in property damage, serious
personal injury, or death.
ELECTRICAL HAZARD!
Grounding Required! Follow proper local and state electrical
code on requirements for grounding. Failure to follow this
warning could result in property damage, serious personal
injury, or death.
HAZARDOUS VAPORS! Do not install an air handler with a
non-ducted return in the same closet, alcove, or utility room
as a fossil fuel device. Hazardous vapors can be distributed
throughout the conditioned space and equipment damage can
result.
