14. INSTALLATION OF REMOTE CONTROLLER
14.1. INSTALLATION OF REMOTE CONTROL SWITCH <PC-ART>
PC-ART
15. TEST RUNNING
When installation is completed, perform test run according to the following procedure, and hand over the system to the customer. Perform test run
regarding indoor units one by one in order, and confirm that the electrical wiring and the refrigerant piping are correctly connected.
Test run should be performed according to the "Test Run Procedure" on next page.
WARNING:
Do not operate the system until all the check points have been
cleared:
Check to ensure that the electrical resistance is more than
−
1 MΩ, 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 impress the voltage on the terminals for transmission 1
and 2.
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 oil heater
Pay attention to the following items 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 heated higher than 90°C.
DO NOT PUSH THE BUTTON OF THE MAGNETIC
−
SWITCH(ES), it will cause a serious accident.
Do not touch any electrical components for more than three
−
minutes after turning OFF the main switch
Confirm that the gas line stop valve and the liquid line stop
−
valve are fully open.
Confirm that the leakage of the refrigerant does not exist.
−
The flare nuts are sometimes loosened by vibration during
transportation.
Check that the refrigerant piping and the electrical wiring
−
conform to the same system.
Confirm that the dip switch setting on the printed circuit board
−
of the indoor units and the outdoor units are correct.
Check whether or not the electrical wiring of the indoor units
−
and the outdoor units are connected as shown in the chapter
ELECTRICAL WIRING".

INSTALLATION AND OPERATION MANUAL
All data related to Installation about Remote Control Switch for PC-ART are in the specific Installation
Manual. Please refer to Installation Manual PMML0177A
CAUTION:
Confirm that field-supplied electrical components (main switch
fuse, fuse-free breaker, earth leakage breakers, wires, conduit
connectors and wire terminals) have been properly selected
according to the electrical data given in the Technical Catalog of
the unit and ensure that the components comply with national and
local codes.
NOTE:
For more reference check Troubleshooting chapter on Operation
−
Part.
For twin, triple and quad check the indoor unit outlet air temperature
−
at test run. If the temperature difference is large (aprox. 10 deg. or
more (cooling) 20 deg. or more (heating) recheck the refrigerant
piping, Installation may have some problem.
In the case of anual cooling optional function, cut JP1 out and set
−
the DSW6-1 to OFF. (Individual control is not available when anual
cooling is selected).
