9.5 SETTING OF DIP SWITCHES
?
N O T E
• 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.

C A U T I O N
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.
9.5.1 DIP Switch Setting of PCB2
(1) DSW1: Unit model setting
No setting is required.
Setting before shipment
(2) DSW3: Capacity setting
No setting is required.
Capacity 44(2.0HP)
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.

N O T E
• Binary encoding method for Refrigeration system No.:
Refrigeration system No.=∑ the value of the pin × 2
the value 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.
Calculation in binary:8=0×2 (1-1)
+0×2 (6-1)
80(3.0HP)
60(2.5HP)
(pin number-1)
+0×2 (2-1) +0×2 (3-1) +1×2 (4-1) +0×2
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.

C A U T I O N
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.
