Indoor unit Outdoor unit Power cable 3G1.5mm2 Connecting wiring : 4G1.5mm2 5 Outdoor unit Outdoor unit 1.Installation of Outdoor Unit Install according to Drawing for the installation of indoor and outdoor units 2.Connection of pipes To bend a pipe, give the roundness as large as possible not to crush the pipe ,and the bending radius should be 30 to 40 mm or longer. Connecting the pipe of gas side first makes working easier. The connection pipe is specialized for R410A. Half union Flare nut Forced fastening without careful centering may damage the threads and cause a leakage of gas. Spanner Torque wrench Pipe Diameter Fastening torque Liquid side 6.35mm(1/4") 18N.m Gas side 9.52mm(3/8") 42N.m Be careful that matters, such as wastes of sands, etc. shall not enter the pipe. The standard pipe length is 5m. If it is over 5m, 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. CAUTION In case the elevation A is more than 5m, oil trap shoud be installed every 5~7m Max. Length: Bmax=15mMax.Elevation: Amax=10m In case the pipe length B is more than 10m, the refrigerant should be charged, according to 20 g/m. In case A is more than 5m A B Outdoor unit Indoor unit A B Outdoor unit Indoor unitA B Outdoor unit Indoor unit Oil trap 3.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. 4.Attaching Drain-Elbow If the drain-elbow is used, please attach it as figure. (Note: Only for heat pump unit.) 6 Outdoor unit Outdoor unit 2-way valve 5.Purging Method:To use vacuum pump 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 (Iow) for gaugemanifold. Then connect the projection of charge hose (center) for gaugemanifold into vacuum pump. Open the handle at Iow in gaugemanifold, operate vacuum pump. If the scale-moves of gause (Iow) reach vacuum condition in a moment, check again. Vacuumize for over 15min. And check the level gauge which should read -0.1 MPa (-76 cm Hg) at Iow pressure side. After the completion of vacuumizing, close the handle 'Lo' in gaugemanifold and stop the operation of the vacuum pump. Check the condition of the scale and hold it for 1-2min. If the scale-moves back in spite of tightening, make flaring work again, the return to the beginning of 1 . 1 2 3 3 Anti countercurrent joint Vacuum pump(for R410A) 3-way valve Gas Side Gaugemanifold(for R410A) Liquid Side Tube(for R410A) Open Close 2-way valve Service port cap 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. No gas leakage? In case of gas leakage, tighten parts of pipe connection. If leakage stops, then proceed steps. Detach the charge hose from the service port, open 2-way valve and 3-way. Turn the valve rod anticlockwise until hitting lightly. To prevent the 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. After attaching the each caps, check the gas leakage around the caps. If it does not stop gas leakage, discharge whole refrigerants from the service port. After flaring work again and vacuumize, fill up prescribed refrigerant from the gas cylinder. 3-way valve 2-way valve 7 6 6 6 4 5 6 7 8 3-way valve 2-way valve 3-way valve Valve rod cap Valve rod cap 7 7 Open 90O 2-way valve 3-way valve CAUTION: 1.If the refrigerant of the air conditioner leaks, it is necessary to discharge all the refrigerant. Vacuumize first, then charge the liquid refrigerant into air conditioner according to the amount marked on the name plate. 2.Please do not let other cooling medium, except 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. 7 1.Cut pipe 3.Insert the flare n...
