Test Run; Before Test Run - Hitachi RPC-1.5FSN3 Installation & Maintenance Manual

8.

Test Run

Test run should be performed according to this
manual and "Installation & Maintenance Manual" of
the outdoor unit.
Do not operate the system until all the check points
have been cleared.
l 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.
l Do not touch any of the parts at the discharge
gas side by hand while the system is running,
since the compressor chamber and the pipes
at the discharge side are heated higher than
o
90 C.
l Check to ensure that the stop valves of the
outdoor unit are fully opened, and then start the
system.
l Check to ensure that the switch on the main
power source has been ON for more than
12 hours, to warm the compressor oil by the
crankcase heater.
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 (A, B, 1 and 2)).

(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.
