.
(A) Ensure
that
the
stop
valves
of the
outdoor
unit
are
fully
opened.
(B) Ensure that the electric wires have been fully connected.
(C) 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

the
following
items
while the
system
is
running
.
Do not touch any of the parts by hand at the discharge gas side
.
Compressor chamber and pipes at the discharge
side will reach temperatures in excess of 194
℉（
90
℃）.
T
est run should be performed after refrigerant piping, drain, wiring, etc. have been finished.
The air conditioner is provided with a crankcase heater. Ensure that the main power supply has been
turned ON for more than 6 hours ahead of power on preheating. Failure to do so may damage the
compressor.
●
Turn off the power
after test run is finished.
Installation of the equipment is complete after concluding the test run. For additional information, contact local
