Panasonic S-140MH1H5 Installation Instructions Manual page 3

CAUTION • Keep the fire alarm and
WARNING
the air outlet at least 1.5 m
away from the unit.
• 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.
...In Moist or Uneven Locations
Use a raised concrete pad or concrete
blocks to provide a solid, level foundation
for the outdoor unit. This prevents water
damage and abnormal vibration.
...In an Area with High Winds
Securely anchor the outdoor unit down
with bolts and a metal frame. Provide a
suitable air baffle.
...In a Snowy Area (for Heat Pump-
type Systems)
Install the outdoor unit on a raised
platform that is higher than drifting snow.
Provide snow vents.
...At least 2.5 m
Indoor unit of this air conditioner shall be
installed in a height of at least 2.5 m.
...In laundry rooms
Do not install in laundry rooms. Indoor unit
is not drip proof.
When Connecting Refrigerant Tubing
• When performing piping
work do not mix air except
for specified refrigerant
(R410A) in refrigeration
cycle. It causes capacity
down, and risk of
explosion and injury due
to high tension inside the
WARNING
refrigerant cycle.
WARNING
• Refrigerant gas leakage
may cause fire.
• Do not add or replace
refrigerant other than
specified type. It may
cause product damage,
burst and injury, etc.
• Ventilate the room well, in the event
that is refrigerant gas leaks during
the installation. Be careful not to allow
contact of the refrigerant gas with a
flame as this will cause the generation
of poisonous gas.
• Keep all tubing runs as short as
possible.
• Use the flare method for connecting
tubing.
• Apply refrigerant lubricant to the
matching surfaces of the flare and union
tubes before connecting them, then
tighten the nut with a torque wrench for
a leak-free connection.
• Check carefully for leaks before starting
the test run.
• Do not leak refrigerant while piping work
for an installation or re-installation, and
while repairing refrigeration parts.
Handle liquid refrigerant carefully as it
may cause frostbite.
