8.3.9.5 SETTING OF DIP SWITCHES

●
The mark "■" indicates the dip switches positions.
●
No mark "■" indicates pin position is not affected.
●
The figures show the settings before shipment or after
selection.
●
"Not used" means that the pin must not be changed.
A malfunction might occur if changed.
Before setting dip switches, first turn the power supply OFF
and then set the position of dip switches. If the switches are
set without turning the power supply OFF, the contents of the
setting are invalid.

(1) DSW1: Unit model setting
No setting is required.
Setting before shipment
(2) DSW3: Capacity setting
No setting is required.

Setting before shipment
(3) DSW5: End resistance setting
No setting is required.
Setting before shipment
(4) DSW6: Refrigeration system No. setting
Setting is required. Use binary encoding method.
Setting before shipment
Max No.63 are available to set when all the equipment are
connected to corresponding H-NET.
● Binary encoding method for Refrigeration system No.:
Refrigeration system No.=∑ the value of the pin × 2
of the pin: the value is equal to 1 when the pin is set as ON, otherwise
the value is equal to 0.
Pin number: the figure below the pin, marked as 1~6.
Ex.) Set refrigeration system No. as 8.

8.3.10 TEST RUN

When installation is completed, perform test run according
to the wired remote controller's manual, and hand over the
system to the customer.
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.
● 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 within 10 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 settings on the printed circuit
board of the indoor unit and the outdoor unit are correct.
-
Check whether or not the electrical wirings of the indoor
unit and the outdoor unit are connected properly.
