REFRIGERANT PIPING
Allowable Piping Length
If the
pipe
is
too
long,
both the
capacity
and reliability
of
the unit
will
drop.
As
the number of
bends
increases,
resistance
to
the
flow
of
refrigerant
system
increases, thus lowering
cooling capacity.
As
a
result,
the
compressor
may
become
defective.
Always choose
the shortest path and
follow
the recommendations
as
tabulated
below:

"'Be sure
to
add
the proper amount
of additional refrigerant.
Failure to do
so may
result in reduced
perfonnance.
Remark: TIle refrigerant pre-charged in the
outdoor
unit
is
for
piping
length up
to
7.5m.

Notes:
1.
Equivalent
piping length
is
obtained
with
acntallength of gas
piping.
2.
90°
bend
of
piping is equivalent
to L
joint.
Bending mnst
be carefully
made
so
as
not to
cmsh
the
pipe.
Use a
pipe
bender
to
bend a
pipe
where
possible.
