●
Flaring work
○
Make
sure
that
the
unit
is
stable
in
installation.
Fix
the
unit
to
stable
base.
○
When
installing
the
unit
at
a
higher
place
or
where
it
could
be
toppled
by
strong
winds,
secure
the
unit
firmly
with
foundation
bolts,
wire,
etc.
○
Execute drain piping by using a drain elbow and drain grommets supplied
separately as accessories, where water drained from the outdoor unit is a
problem.
○
Water may drip where there is a larger amount of drain water. Seal
around the drain elbow and drain grommets with putty or adequate
caulking material.
○
Condensed water may flow out from vicinity of service valve or
connected pipes.
○
Where you are likely to have several days of sub-zero temperatures in a
row, do not use a drain elbow and drain grommets. (There is a risk of
drain water freezing inside and blocking the drain.)
Electric wiring work
○
Perform
wiring,
making
wire
terminal

conform
to

Always perform grounding system installation work with the power cord unplugged.
○
Connect a pair bearing a common terminal number with an indoor-outdoor connecting wire.
○
In cabling, fasten cables securely with cable clamps so that no external force may work on terminal connections.
○
Grounding terminals are provided in the terminal block.
Always use an earth leakage circuit breaker designed for inverter
circuits to prevent a faulty operation.
○
The specifications shown in the above table are for units without heaters. For units with heaters, refer to the
installation instructions or the construction instructions of the indoor unit.
○
Switchgear or Circuit breaker capacity which is calculated from maximum over current should be chosen along the
regulations in each country.
○
The cable specifications are based on the assumption that a metal or plastic conduit is used with no more than
three cables contained in a conduit and a voltage drop is 2%. For an installation falling outside of these
conditions, follow the internal cabling regulations. Adapt it to the regulation in effect in each country.
