8. Test Run
Test run should be performed according to
“Installation & Maintenance Manual” of the outdoor
unit.
O
Do not operate the system until all the check
points have been cleared.
(A) Check to ensure that the electrical
resistance is more than 1 megohm,
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.
(B) Check to ensure that the stop valves of
the outdoor unit are fully opened, and
then start the system.
(C) Check to ensure that the main power
source has been turned ON for more than
12 hours, to warm the compressor oil by
the crankcase heater.
O
Pay attention to the following items while the
system is running.
(A) 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 heated higher than
90
o
C.
(B) DO NOT PUSH THE BUTTON OF THE
MAGNETIC SWITCH(ES). It will cause a
serious accident.
8.1 Before Test Run
Recheck that there is not any problems to the
installation, and do not perform the test run until all
the following checking points have been cleared.
(1) Check to ensure that the refrigerant piping
and the transition wiring are connected to the
same refrigerant cycle system. If not, it will
cause an abnormal operation and breakage
of instruments.
(2) Check to ensure that the electrical resistance
is more than 1 megohm, 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. Do not apply the high
voltage to the terminals for the transmission
(TB2 (1, 2, A and B)).
(3) Check to ensure that each wire is correctly
connected at the power source. If incorrectly
connected, the unit will not operate and the
remote control switch will indicate the alarm
code “05”. In this case, check the phase
of the primary power source according to
the attached attention label on the rear side
of the service cover. Then, perform the
reconnection work correctly with turning OFF
the power supply.
(4) Check to ensure that the main power source
has been turned ON for more than 12 hours,
to warm the compressor oil by the crankcase
heater.
8.2 Test Run
After the installation work is completed, test run
should be performed.
(1) Check to ensure that stop valves (gas and
liquid) of the outdoor unit are fully opened.
(2) In the case that indoor units are connected
to the VRF system, perform the test run of
the indoor unit one by one sequentially and
then check accordance of the refrigerant
piping system and the electrical wiring
system. (If the multiple indoor units are
operated simultaneously, the system can not
be inspected the system accordance.)
(3) Perform the test run according to the
following procedure. Ensure that the test run
is carried out without any problem.
(a) Press and hold “ ” (menu) and “ ” (return)
simultaneously for at least 3 seconds.
The test run menu will be displayed.
1) The test run menu will be displayed.
