Safety Considerations
• Read these
Safety Considerations
carefully to ensure
correct installation.
• This manual classifies the precautions into
DANGER
,
WARNING
and
CAUTION
.
Be sure to follow all the precautions below: they are all
important for ensuring safety.
DANGER �����������
Indicates an imminently hazardous
situation which, if not avoided, will
result in death or serious injury.
WARNING ���������
Failure to follow any of WARNING
is likely to result in such grave
consequences as death or serious
injury.
CAUTION ����������
Failure to follow any of CAUTION
may in some cases result in grave
consequences.
• After completing installation, test the unit to check for
installation errors. Give the user adequate instructions
concerning the use and cleaning of the unit according to the
Operation Manual.
DANGER
• Refrigerant gas is heavier than air and replaces oxygen.
A massive leak could lead to oxygen depletion, especially
in basements, and an asphyxiation hazard could occur
leading to serious injury or death.
• If the refrigerant gas leaks during installation, ventilate the
area immediately.
Refrigerant gas may produce a toxic gas if it comes
in contact with fire such as from a fan heater, stove or
cooking device.
Exposure to this gas could cause severe injury or death.
• After completing the installation work, check that the
refrigerant gas does not leak.
Refrigerant gas may produce a toxic gas if it comes
in contact with fire such as from a fan heater, stove or
cooking device.
Exposure to this gas could cause severe injury or death.
• Do not ground units to water pipes, telephone wires or
lightning rods because incomplete grounding could cause
a severe shock hazard resulting in severe injury or death,
and to gas pipes because a gas leak could result in an
explosion which could lead to severe injury or death.
• Safely dispose of the packing materials.
Packing materials, such as nails and other metal or
wooden parts, may cause stabs or other injuries.
Tear apart and throw away plastic packaging bags so that
children will not play with them.
Children playing with plastic bags face the danger of death
by suffocation.
