SPECIAL PRECAUTIONS
When Wiring
WARNING
ELECTRICAL SHOCK CAN
CAUSE SEVERE PERSONAL
INJURY OR DEATH. ONLY A
QUALIFIED, EXPERIENCED
ELECTRICIAN SHOULD
ATTEMPT TO WIRE THIS
SYSTEM.
• This equipment is strongly recommended
to be installed with Earth Leakage
Circuit Breaker (ELCB) or Residual
Current Device (RCD). Otherwise, it may
cause electrical shock and fire in case
of equipment breakdown or insulation
breakdown.
When Installing...
Check the following to use the FRESH
AIR INTAKE MODE.
WARNING
• Install the outdoor air intake port in
an area where the combustion gas
cannot be inhaled.
If safety issues exist, the room
becomes oxygen-deprived and this
will cause the fatal accident.
• Do not make air around the
discharge air outlet lead to the
outdoor air intake port. The indoor air
is contaminated and this causes the
health problem.
CAUTION
W
• In the area where the temperature
inside the unit becomes below 0°C
due to cold air in cold climates,
install the electrical damper onto
the outdoor air duct for antifreeze
measurement.
• Select the installation location where
the temperature and humidity are
within the usability range.
If the relative humidity inside the
ceiling exceeds 80%, measure
against the condensation (additional
insulation, etc.)
• Be sure to insulate the piping to
protect the condensation.
In the case of insufficiency, water
may enter the building and this may
cause damage to the furniture or
interiors, etc.
•
Install the piping to be slightly
slanting to the outdoor side.
In the case of insufficiency, rain
drops may enter the building and
damage the furniture or cause
electric shock and fire.
•
Avoid the area where sulfurous acid
gas, corrosive gas or salt erosion
potentially occur. This may cause
corrosion to the copper tube and
brazing part.
As a result, refrigerant gas may leak.
