EXPLOSION HAZARD
Failure to follow this warning could
result in death, serious personal injury,
and/or property damage.
Never use air or gases containing oxygen
for leak testing or operating refrigerant
compressors. Pressurized mixtures of air
or gases containing oxygen can lead to an
explosion.
WARNING
This appliance is not intended for use by persons (including children)
with reduced physical, sensory or mental capabilities, or lack of
experience and knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsible for
their safety. Children should be supervised to ensure that they do not
play with the appliance.
WARNING
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or
improper operation.
Do not bury more than 36 in. (914 mm) of refrigerant pipe in the
ground. If any section of pipe is buried, there must be a 6 in. (152
mm) vertical rise to the valve connections on the outdoor units. If
more than the recommended length is buried, refrigerant may
migrate to the cooler buried section during extended periods of
system shutdown. This causes refrigerant slugging and could
possibly damage the compressor at start-up.
CAUTION
FOR FLAMMABLE REFRIGERANTS
Do not use means to accelerate the defrosting process or to clean, other
than those recommended by the manufacturer.
The appliance shall be stores in a room without continually operating
ignition sources (for example: open flames, an operating gas appliance
or an operating electric heater).
Do not burn or pierce.
Be aware that refrigerants may not contain an odor.
