·
With tape material along the wire wrapped, sealed wiring holes, prevent the condensed water leaks and insects.
·
Tightly
secure
the
power
source
wiring using
the
cord
clamp
inside
the
unit
.
Note
:
Fix
the
rubber
bushings
with
adhesive
when conduit
tubes
to
the
outdoor
unit
are
not
used
.
General
Check
(1)
Make
sure
that
the
field
-
selected
electrical components
(
main
power
switches
,
circuit breakers
,
wires
,
conduit
connectors
and wire
terminals
)
have
been
properly selected
according
to
the
electrical
data
.
Make
sure
that
the
components
comply with
National
Electrical
Code
(
NEC
).
(2)
Check
to
ensure
that
the
voltage
of
power supply
is
within
±
10
%
of
nominal
voltage and
earth
phase
is
contained
in
the
power supply
wires
.
If
not
,
electrical
parts
will
be damaged
.
(3)
Check
to
ensure
that
the
capacity
of
power supply
is
enough
.
If
not
,
the
compressor
will
not
be
able
to operate
because
of
abnormal voltage
drop
at
starting
.
(4)
Check
to
ensure
that
the
earth
wire
is connected
.
(5)
Install
a
main
switch
,
multi
-
pole
main
switch
with
a
space
of
1/8 in. (3.5mm)
or
more, single phase
main
switch
with
a
space
of 1/8 in. (3.0mm) or
more
between
each
phases
.
(6) Check
to
ensure
that
the
electrical resistance
is
more
than
2M
Ω,
by measuring
the
resistance
between
ground
and
the terminal
of
the
electrical
parts
.
If
not
,
do
not
operate
the
system
until
the electrical
leakage
is
found
and
repaired
.
·
Turn OFF the main power switch of the indoor unit and the outdoor unit and wait for more than 3 minutes before
.
electrical wiring work or a periodical check is performed
·
Check to ensure that the indoor fan and the outdoor fan have
stopped
before
electrical
wiring
work
or
a
periodical
check
is performed
.
·
Protect the wires electrical parts etc from rats or other small animals If not protected rats may gnaw at
,
,
.
.
,
unprotected parts and at the worst a fire will occur
,
.
·
Avoid the wiring from touching the refrigerant pipes plate edges and electrical parts inside the unit
,
.
,
.
If so, the wires will be damaged and at the worst a fire will occur
·
Install an ELB (Electric Leakage Breaker) in the power source
.
,
.
If ELB is not used it will cause electric shock or fire at the worst
,
·
This unit uses an inverter which means that it must be used with an earth leak detector capable of handling
harmonics in order to prevent malfunctioning of the earth leak detector itself.
·
Do not use intermediate connection wires, stranded wires(see
“Attentions when
Connecting the Power Supply
Wiring
”, extension cables or control line connection, because the use of these wires may cause heating, electric
shock or fire.
.
·
The tightening torque of each screw is shown as follows
:
.
· . . . ·
M4 0.7 to 1 0 lbf ft (1 0 to 1 3 N m)
M5 1.5 to 1.8 lbf ft (2 0 to 2 5 N m)
:
· .
. . ·
M6 3.0 to 3.7 lbf ft (4 0 to 5 0 N m)
:
· .
. . ·
M8 6.6 to 8.1 lbf ft (9 0 to 11 0 N m)
:
· .
.
. ·
M10 13.3 to 17.0 lbf ft (18 0 to 23 0 N m)
:
· .
.
. ·
Keep the above tightening torque during wiring work
.
WARNING
CAUTION
Installation instructions
Stand the cylinder upright when filling.
There is a siphon pipe inside,so the cyliner
need not to be upside-down to fill with liquid.
Turn
the cylinder upside -down when filling.
Stand the cylinder upright when filling.

Filling other cylinders
The unit has been filled with refrigerant.
Please calculate additional charge according to “Piping Requirement” .
After finishing vacuum pump procedures, first exhaust air
from charge hose, then open valves, charge refrigerant
as “liquid” type through liquid stop valve.
At the end, please close valves and record
the
refrigerant
