Be careful that mater, such as wastes of sands, etc. shall not enter the pipe.

The standard pipe length is 4 m, if it is over 7 m, the function of the unit will be affected. If the pipe has to be lengthened, the refrigerant should be charged according to 20 g/m. But the charge of refrigerant must be conducted by professional air conditioner engineer. Before adding additional refrigerant, perform air purging from the refrigerant pipes and indoor unit using a vacuum pump, then charge additional refrigerant.

• Maximum elevation: (A) max = 10 m
- In case the elevation (A) is more than 5 m, oil trap should be installed every 5 to 7 m
• Maximum length: (B) max = 15 m
- In case the pipe length B is more than 7 m, the refrigerant should be charged, according to 20 g/m.

connection

• Use the same method on indoor unit. Loosen the screws on terminal block and insert the plugs fully into terminal block, then tighten the screws.
• Insert the cable according to terminal number in the same manner as the indoor unit.
• If wiring is not correct, proper operation can not be carried out and controller may be damaged.
  • Fix the cable with a clamp.

attaching a drain elbow

- If a drain elbow is used, please attach it as figure. (Note: Only on heat pump units.)

using a vacuum cleaner as purging method

1. Detach the service port's cap of 3-way valve, the valve rod's cap for 2-way valve and 3-way's, connect the service port into the projection of charge hose (low) for gauge manifold. Then connect the projection of charge hose (center) for gauge manifold into vacuum pump.
2. Open the handle at low in gauge manifold, operate vacuum pump. If the scale moves of gauge (low) reach vacuum condition in a moment, check 1 again.
3. Vacuum for over 15 minutes and check the level gauge which should read -0,1 MPa (76 cm Hg) at low pressure side. After the completion of vacuum, close the handle "LO" in gauge manifold and stop the operation of the vacuum pump. Check condition of the scale and hold it for 1-2 min. If the scale moves back in spite of tightening, make flaring work again, the return to the beginning of 3.
4. Open the valve rod for the 2-way valve to an angle of anticlockwise 90 degrees. After 6 seconds, close the 2-way valve and make the inspection of gas leakage.
5. No gas leakage?
   In case-of gas leakage, tighten parts of pipe. If leakage stops, then proceed to step 6.
   If it does not stop, discharge whole refrigerants from the service port. After flaring work again and vacuum, fill up prescribed refrigerant from the gas cylinder.
6. Detach the charge hose from the service port, open 2-way valve and 3-way. Turn the valve rod anticlockwise until hitting lightly.
7. To prevent gas leakage, turn the service port's cap. The valve rod's cap for 2-way valve and 3 way's a little more than the point where the torque increases suddenly.
8. After attaching each cap, check for gas leakage around the caps.

CAUTION

- If the refrigerant of the air conditioner leaks, it is necessary to discharge all the refrigerant. Vacuum first, then charge the liquid refrigerant into air conditioner according to the amount marked on the name plate.

- Please do not let other cooling medium except the specified one (R410A) or air enter into the cooling circulation system. Otherwise there will be abnormal high pressure in the system to make it crack and lead to personal injuries.

power source

• The power source must be exclusively used for air conditioner (over 10 A).
• In case of installing an air conditioner in a moist place, please install a ground leakage breaker.
• For installation in other places, use a circuit breaker as far as possible.

Cutting and flaring work of piping

- Pipe cutting is carried out with a pipe cutter and burs must be removed.

4. Flare pipe.

1. Cut pipe

2. Remove burs

Correct Incorrect
	Lean Damagedflare

3. Insert flare nut

Correct Incorrect
	Partialflare	Flare too large

drainage

• Install the drain hose so as to be downward slope without fail.
- Do not install the drainage as shown below.

Too high midway

End immersed in water

Waves

Clearance with floor is too small

Bad odor from ditch

• Pour water in the drain pan of the indoor unit and confirm that drainage is carried out securely outdoors.
• In case that the attached drain hose is in a room, please apply heat insulation to it without fail.
