shipment is “Wireless”.
* In case of using the wired remote control (PC-ARF(P)
(1)(E)) and the receiver kit (PC-ALHZ1), set the SW2 to
“Wired”. If not, the operation is not available. Connect the
remote control switch cables to terminals A and B at the
terminal board TB2.

The “■” mark indicates position of dip switches. Figures show setting
before shipment.
•
When the unit number and the refrigerant cycle are set, record the unit
number and refrigerant cycle to facilitate maintenance and servicing
activities thereafter.
•
Turn OFF all the power supply of the indoor unit and the outdoor unit
before Dip Switch setting. If not, the setting is invalid.
•
In case of using the wired remote control or receiver kit
PC-ALHZ1 set the SW2 to “Wired”.
19 TEST RUN
Test run should be performed according to this manual and
“Installation & Operation Manual” of the outdoor unit.

•
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 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 90ºC.

•
Check to ensure that the stop valves of the outdoor unit are fully
opened, and then start the system.
•
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.
19.1 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
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 phase of 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.

For wired remote control switch (PC-ARF(P)(1)(E)), set
the SW2 to “Wired” because the setting before shipment is
“Wireless”. If not, the operation is not available.

The RUN indicator on indoor unit is turned ON even when the wired
remote control switch is used. However, the indication for timer settings
are only indicated on the wired remote control switch.
5
For the indoor unit wall type without expansion valve, check
that the optional expansion valve kit is installed without fail
before test run.
19.2 START TEST RUN
After the installation work is completed, test run should be
performed.
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.).
For more information, please refer to remote control “Installation
& Operation Manual”.
