When Transporting; When Installing; When Connecting Refrigerant Tubing - Panasonic U-8ME1E81 Service Manual

When Transporting

Be careful when picking up and moving
the indoor and outdoor units. Get a
partner to help, and bend your knees
when lifting to reduce strain on your back.
Sharp edges or thin aluminum fins on the
air conditioner can cut your fingers.

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.
CAUTION
Keep the fire alarm and the air
outlet at least 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

WARNING
• 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.
• 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.
