If the damage is left uncorrected, the unit will fall and
cause serious injury.
Consult your dealer for the proper disposal
of the unit.
The refrigerant oil and the refrigerant in the unit will

The unit shall be properly stored to prevent
mechanical damage.
Check that markings of the unit are not illeg-
ible.
Illegible warning or caution markings may cause dam-
age to the unit, resulting in injury.
If the ambient temperature can drop below
freezing while the heat-source unit is not in
use, blow the water out of the pipes or fill
them with anti-freeze solution.
Failure to do so may cause the water in the pipes to
freeze and damage the unit.
Water from burst pipes may result in water-damage to
the furnishings.
Make sure the supply-water flow rate falls
within the specified range.
Failure to maintain the adequate flow rate can result in
corrosion of the heat-source unit.
Water from corroded pipes can result in water-damage
to the furnishings.
