WARNING
HAZARDOUS VAPORS!
Failure to follow this caution could result in property
damage or personal injury. Equipment corrosion damage.
To prevent shortening its service life, the unit should not
be used during the finishing phases of construction or
remodeling. 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.
!
WARNING
RISK OF FIRE!
Failure to following this warning could result in serious
injury, death, or property damage.
The following requirements apply to the room where the
cased coil is installed:
All combustion appliances located in the same room
that have continuous pilot lights are equipped with an
effective flame arrest.
Auxiliary devices which may be a potential ignition
source, such as hot surfaces or electric switching
devices, shall not be installed in the connecting ductwork
unless they have been approved by the manufacturer or
declared suitable with the refrigerant used.
All indoor field-made joints of the field piping have
been checked for refrigerant leaks after charging
using an electronic leak detector calibrated for R-454B
having a sensitivity of 5 grams per year or better.
The room is constructed to ensure that should any
refrigerant leak it will not stagnate and create a fire
hazard.
!
WARNING
PRESSURIZED REFRIGERANT!
Failure to follow this Warning could result in personal
injury.
System contains oil and refrigerant under high pressure.
Recover refrigerant to relieve pressure before opening
the system. Do not use non-approved refrigerants or
refrigerant substitutes or refrigerant additives.
