COMPRESSOR
CRITERIA
1
Strictly
obser
ve
the
speci
ficati
on
The
compressor
should
be used
in specifications
written
in
this
"compressor specification"
and
not
be used
in
specifications outside
it
..
The
main
circuit
must link
up with fuse
or breaker.
2 Source voltage
Spec
ified inverter is
linked up
with
compressor terminals
.
Applied
vol
tage of this
inver ter
shoul
d
be
vol
tage
specified
in
this "compressor speci
f
ication".
Al
ternating
vo
l
tage
should
never
be applied
on
terminals
(for
exampl
e: commercial alternating
vol
tage of l<j>lOOV, 200V, 3<j>200V)
.
Thi
s
i
s
because that if applied a
l
ternating
current
the
direct
current motor
wi
ll
demagnetize.
3 Operating
voltage range
The compressor
should
be
operated
in
the
range
of
rated
vol
tage
±10%
, under
standar
d
condition
and overload condition
of
rated
frequency (applied
voltage
to
inverter
)
.
It must be satisfied
with
item
5
,6,
7.
4
Operating
temperatures
and pressures
The operating
temperatur
es and
pr
essures
of
a
compressor
should
be
within
the
range shown
in
the
table
2 and
graph
1.
5
Oil
Back
and
height of the
oi
l
level
Oil
shoul
d
be returned continuously
to
the compressor and not kept in the refrigeration
system.
Oil
level
of
compressor
should
be
hi
gher
than
7.
5
mm
from the
lubr
icating piece fixed on
the end
of
the
crankshaf
t
.
Compressor
must not be
started
operated
under a
dual-layer
separate
status.
However,
in
case of foaming
s
i
tuation,
the height
of
this foam
does
not mean
the height
of
the
oil level.
If
you
do not keep the
oil
l
evel, the
oil shor
tage
will occur, and
influence
the
r
eliability of
compressor
.
(Please
check
the
oil level in the compressor with the
sight
glass
we
supply.
