Installation dimension diagram

To ensure safety, please be mindful of the following precautions.

Warning

• When installing or relocating the unit, be sure to keep the refrigerant circuit free from air or substances other than the specified refrigerant.
  Any presence of air or other foreign substance in the refrigerant circuit will cause system pressure rise or compressor rupture, resulting in injury.

- When installing or moving this unit, do not charge the refrigerant which is not comply with that on the nameplate or unqualified refrigerant.

Otherwise, it may cause abnormal operation, wrong action, mechanical malfunction or even series safety accident.

- When refrigerant needs to be recovered during relocating or repairing the unit, be sure that the unit is running in cooling mode. Then, fully close the valve at high pressure side (liquid valve). About 30-40 seconds later, fully close the valve at low pressure side (gas valve), immediately stop the unit and disconnect power. Please note that the time for refrigerant recovery should not exceed 1 minute.

If refrigerant recovery takes too much time, air may be sucked in and cause pressure rise or compressor rupture, resulting in injury.

- During refrigerant recovery, make sure that liquid valve and gas valve are fully closed and power is disconnected before detaching the connection pipe. If compressor starts running when stop valve is open and connection pipe is not yet connected, air will be sucked in and cause pressure rise or compressor rupture, resulting in injury.

- When installing the unit, make sure that connection pipe is securely connected before the compressor starts running.

If compressor starts running when stop valve is open and connection pipe is not yet connected, air will be sucked in and cause pressure rise or compressor rupture, resulting in injury.

- Prohibit installing the unit at the place where there may be leaked corrosive gas or flammable gas.

If there leaked gas around the unit, it may cause explosion and other accidents.

- Do not use extension cords for electrical connections. If the electric wire is not long enough, please contact a local service center authorized and ask for a proper electric wire.

Poor connections may lead to electric shock or fire.

- Use the specified types of wires for electrical connections between the indoor and outdoor units. Firmly clamp the wires so that their terminals receive no external stresses.

Electric wires with insufficient capacity, wrong wire connections and insecure wire terminals may cause electric shock or fire.

Configuration of connection pipe

1. Standard length of connection pipe

- 5m, 7.5m, 8m.

1. Min. length of connection pipe is 3m.

2. Max. length of connection pipe.

Cooling capacity	Max length of connec-tion pipe
5000Btu/h (1465W)	15 25
7000Btu/h (2051W)	15 30
9000Btu/h (2637W)	15 30
12000Btu/h (3516W)	20 30
18000Btu/h (5274W)	25 30

Cooling capacity	Max length of connection pipe
24000Btu/h (7032W)
28000Btu/h (8204W)
36000Btu/h (10548W)
42000Btu/h (12306W)
48000Btu/h (14064W)

1. The additional refrigerant oil and refrigerant charging required after prolonging connection pipe

- After the length of connection pipe is prolonged for 10m at the basis of standard length, you should add 5ml of refrigerant oil for each additional 5m of connection pipe.

- The calculation method of additional refrigerant charging amount (on the basis of liquid pipe):

Additional refrigerant charging amount = prolonged length of liquid pipe × additional refrigerant charging amount per meter

- Basing on the length of standard pipe, add refrigerant according to the requirement as shown in the table. The additional refrigerant charging amount per meter is different according to the diameter of liquid pipe. See the following sheet.

Configuration of connection pipe

Additional refrigerant charging amount for R22, R407C, R410A and R134a

Diameter of connection pipe		Outdoor unit throttle
Liquid pipe(mm)	Gas pipe(mm)	Cooling only(g/m)	Cooling and heating(g/m)
Φ6	Φ9.52 or Φ12	15	20
Φ6 or Φ9.52	Φ16 or Φ19	15	50
Φ12	Φ19 or Φ22.2	30	120
Φ16	Φ25.4 or Φ31.8	60	120
Φ19	-	250 250
Φ22.2	-		350350

Pipe expanding method

Note:

Improper pipe expanding is the main cause of refrigerant leakage. Please expand the pipe according to the following steps:

A: Cut the pipe

• Confirm the pipe length according to the distance of indoor unit and outdoor unit.
• Cut the required pipe with pipe cutter.

B: Remove the burrs

- Remove the burrs with shaper and prevent the burrs from getting into the pipe.

C: Put on suitable insulating pipe

D: Put on the union nut

- Remove the union nut on the indoor connection pipe and outdoor valve; install the union nut on the pipe.

E: Expand the port

- Expand the port with expander.

Note:

- "A" is different according to the diameter, please refer to the sheet below:

Outer diameter (mm)	A(mm) Max Min
Φ6 - 6.35(1/4")	1.3 0.7
Φ9.52(3/8")	1.6 1.0
Φ12-12.7(1/2")	1.8 1.0
Φ15.8-16(5/8")	2.4 2.2

F: Inspection

- Check the quality of expanding port. If there is any blemish, expand the port again according to the steps above.
