Panasonic U-4LE1E5 Installation Instructions Manual page 4

When Installing...
Select an installation location which is rigid and strong
enough to support or hold the unit, and select a location
for easy maintenance.
...In a Room
Properly insulate any tubing run inside a room to prevent
"sweating" that can cause dripping and water damage to
walls and floors.
Keep the fire alarm and the air outlet at least
CAUTION
1.5 m away from the unit.
...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.
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 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.
AMP Air Conditioning
Handle liquid refrigerant carefully as it may cause
frostbite.
When Servicing
• Turn the power OFF at the main power box
(mains) before opening the unit to check or repair
electrical parts and wiring.
• Keep your fingers and clothing away from any moving
parts.
• Clean up the site after you finish, remembering to
check that no metal scraps or bits of wiring have been
left inside the unit being serviced.

cleaning.
• In case of malfunction of this
appliance, do not repair by yourself.
Contact the sales dealer or service
dealer for repair.
• Do not touch the air inlet or the
sharp aluminum fins of the
outdoor unit. You may get injured.
CAUTION
• Ventilate any enclosed areas when
installing or testing the refrigeration
system. Escaped refrigerant gas, on
contact with fire or heat, can produce
dangerously toxic gas.
• Confirm after installation that no
refrigerant gas is leaking. If the gas
comes in contact with a burning stove,
gas water heater, electric room heater
or other heat source, it can cause the
generation of poisonous gas.
Others
• Do not touch the air inlet or
