(A) Check
to
ensure
that
the
stop
valves
of the
outdoor
unit
are
fully
opened.
(B) Check to ensure that the electric wires have been fully connected.
(C) 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
.
Test Run Function Identification
Operate
the
thermostat to turn ON the appliance, and then proceed with the test run.
Pay
attention
while the
system
is
running
.
Do not touch any of the parts by hand at the discharge gas side
,
since the compressor chamber and the pipes at the
discharge side are will be at temperatures higher than 194
℉（
90
℃）.
T
est
run
should
be
performed
only
after refrigerant piping, drain, wiring, etc. have been completed.
The air conditioner is provided together with a crankcase heater. Check to ensure that the switch
on the main power source has been ON for more than 6 hours ahead of power on preheating,
otherwise it might damage the compressor!
Do
not
operate
the
system
until
all
of
the following
check points
have
been
cleared
.

(1)
Follow local codes and regulations when selecting field wires. All of the above are the minimum wire size.
(2)
When transmitting cable length is longer than 262ft. (80m), the next larger wire size should be selected.
(3)
Install

When connecting the terminal block using stranded wire, make
sure to use the round crimp-style terminal for connection to the
power supply terminal block. Place the round crimp-style
terminals on the wires up to the covered part, secure in place.

.
When connecting the terminal block using a single-core wire, be
sure to perform proper curing.
