44. Installation  Purpose: eliminating dust, water vapor and oxides caused by welding.  Note: the solid can not be eliminated, so please store the pipes carefully to prevent the solid entering.  Method: 1.Flush the pipe with 0.5 MPa Nitrogen 2.Use your hand to block one of the nozzles 3.When the pressure is too high to block, then remove your hand 4.Repeat the step 3 and 4 to each nozzle 5.After flushing seal all the nozzles Cleaning the pipe:

45. Installation  Vacuum the system 1.Connect the outdoor unit pressure gauge and vacuum pump with a adapter pipe 2.Keep the 3-way-valve closed 3.Start the vacuum, keep running approx 15 mins, when the gauge is down to -0.1MPa. close the gage valve, stop the pump, and maintain for 1-2 mins, if the gauge pointer doesn’t go back, it means there is no leakage and the vacuum is finished. 4. If the pointer goes back, it means there is a leakage, you need to fix it and vacuum again.

46. Installation 5. Open the 2-way-valve and 3-way-valve. 6. Fastening the valve covers. 7. Check the joint leakage. If there is a leakage, you should regain the refrigerant and fix the leakage.

47. Installation  Requirements for adding refrigerant 1.Put the R410a cylinder on the electronic scale, and use an adapter pipe to connect the outdoor unit and cylinder. 2.Keep the cylinder erected, if there is no siphon tube inside, you should keep it upside down. 3. If there is a serious leakage, you should vacuum the system, and then charge. 4. Generally, the refrigerant can not be charged, if the refrigerant quantity in the cylinder is less than 10% Have siphon tube insideWithout siphon tube inside

48. Installation  Adding refrigerant: For newly install AC with extended copper pipe, you need to add refrigerant, please vacuum the system and add refrigerant using the following: 1.Put the R410a cylinder on the electronic scale, close gage the valve and connect the adapter pipe. 2. Open the cylinder valve. 3. Adjust the electronic scale number to zero ， then open the gage valve to charge refrigerant. Control the quantity by the scale 4.Close the gage valve, remove the adapter pipe, close the valve and check for any leakage.

49. Installation  Unit checking after installation 1.Check whether the pipe and cable is packaged. 2. Check whether the ground wire is charged. 3.Check whether the indoor and outdoor units are horizontal and secure. 4.Pour some water on the evaporator, check whether there is any water leakage. 5.Check whether the 2-way valve and 3-way valve are opened. Check whether the ground wire is charged Check whether the indoor and outdoor units are horizontal and secure check whether there is any water leakage

50. Installation Caution:  1.The unit should be placed far away the flammable, explosive or oily place.  2.The noise and the outlet air should not affect the neighbors.  3.There should be enough space for air inlet, air outlet and maintenance around the unit. Fluent ventilation and good heat release.  4.The steel bracket should be strong enough to afford the 1.5 times heavier than the unit running weight. The steel bracket should be horizontal.  5.The outdoor unit should be over 100mm higher than the ground, and there should be the drainage around to ensure the unit not being immersed in the water.  6.The unit should be fixed firmly with the anti-vibration cushion.  7.The outdoor should be as near the indoor as possible. Shorten the pipe and decrease the bend pipe. Pipe length can not exceed the permitted range.
