• When installing the branch pipe, direction and angle of installation is not limited.
• Take care so that burrs and foreign material may not enter into the cutting surface when connecting.
• Don’t use the liquid pipe by too bending or twisting.

Installation
1. Form the piping according to its routing. Avoid bending and bending back the same piping point more than three times. (This will result in hardening the pipe.)
2. After deforming the piping, align centers of the union fitting of the indoor unit and the piping, and tighten them firmly with wrenches.
3. Connect pipe to the service valve or ball valve which is located below the outdoor unit.
4. After completing the piping connection, be sure to check if there is gas leakage in indoor and outdoor connec­tion.

For additional charging method, see below table.
❈ Note: If total additional charge value after calculation comes out to be negative, then do not consider additional
charge.
CAUTION:
• Rated performance for refrigerant line length of:7.5m
• Capacity is based on standard length and maximum allowance length is on the basis of
reliability.
• Improper refrigerant charge may result in abnormal cycle.
• Oil trap should be installed every 10 meters.

4 .Thermal insulation work
• Securely wrap the refrigerant and the branch pipe by using thermal insulation materials provided. When using thermal insulation materials released, use withstand heat insulation materials (thickness of more than 15mm).
• Securely adhere thermal insulation materials
wrapping the branch pipe so that they do not widen. After wrapping them with auxiliary materials
, bound them with a band .
• Finish the work by wrapping with a vinyl tape after the insulation material work.

Wiring Connection
1. All wiring must comply with LOCAL REGULATIONS.
2. Select a power source that is capable of supplying the current as required by the air conditioner.
3. Feed the power source to the unit via a distribution switch board designed for this purpose.
4. The terminal screws inside the control box may be loose due to vibration during transport. Check the screws for loose connection. (Running the air conditioner with loose connection can overload and damage electrical components.)
5. Always ground the air conditioner with a grounding wire and connector to meet the LOCAL REGULATION.
Terminal Block (Outdoor Unit)
Power Input
Terminal Block (Indoor Unit)
The power cord connected to the outdoor unit should be complied with the following specifications (Rubber insulation, type H05RN-F approved by HAR or SAA).
If the supply cord is damaged, it must be replaced by a special cord or assembly available from the manufacturer of its service agent.
The connecting cable connected to the indoor and outdoor unit should be complied with the following specifications (Rubber insulation, type H05RN-F approved by HAR or SAA).

Check the JIG_SW to the right, or not set the JIG_SW to the right.( A )
2. ZONE SW1 Setting
Set the ZONE SW1 as below Table.a ( B )
❈ S/W1 is not used. ❈ 1 means S/W up.
0 means S/W down.
1. Indoor unit connection numbers separation s/w
Accordingly insert the Number pin numbers as below in accordance with the indoor unit connection numbers.( A ) (Inserting order is irrespective.)
3. Auto Addressing Method
1) Turn main power on.
2) Press the S/W_ADDRESSING for about 5~7 seconds( C )
3) Turn the Indoor unit on after 1~2minutes after pressing the s/w.(If performing the ADDRESSING work at the
PCB, the green LED rapidly flickers.)
2. Operation method of pipe length s/w
Convert the s/w toward "long pipe" direction when installing more than main pipe of 30m ( B ).
* Work procedure
1) Set JIG_SW and ZONE SW1 correctly.
2) Turn on main power.
3) Press the TEST_SW1 for about 3 seconds within 3minutes After main power on.( C )
4) After step 3), the LED01T(green LED) rapidly flickers. When Addressing work is done, green LED is off, else LED stops flickering and lights continuously.
5) If you fail to perform the Addressing work, repeat step 2),3).
