Fix the power connection wire and signal control wire with wire clip (only for cooling and heating unit). Note: ● Never cut the power connection wire to prolong or shorten the distance. Step six: neaten the pipes 1. The pipes should be placed along the wall, bent reasonably and hidden possibly. Min. semidiameter of bending the pipe is 10cm. 2. If the outdoor unit is higher than the wall hole, you must set a U-shaped curve in the pipe before pipe goes into the room, in order to prevent rain from getting into the room. wall U-shaped curve drain hose Note: ● The through-wal height of drain hose shouldn't be higher than the outlet pipe hole of indoor unit. ● Slant the drain hose slightly downwards. The drain hose can't be the drain hose can't raise upwards. The drain hose can't be fluctuant ● The water outlet can't be placed in water in order to drain smoothly. The drain hose can't be fluctuant The water outlet can't be placed in water 31 The water outlet can't be fluctuant Vacuum pumping Use vacuum pump 1.

Close the vacuum pump open and maintain this status for 1-2min to check if the pressure of piezometer remains in -0.1MPa. If the pressure decreases, there may be leakage. 5. Remove the piezometer, open the valve core of liquid valve and gas valve completely with inner hexagon spanner. 6. Tighten the screw caps of valves and refrigerant charging vent. Leakage detection 1. With leakage detector: Check if there is leakage with leakage detector. 2. With soap water: If leakage detector is not available, please use soap water for leakage detection. Apply soap water at the suspected position and keep the soap water for more than 3min. If there are air bubbles coming out of this position, there's a leakage. 32 Check after installation ● Check according to the following requirement after ﬁnishing installation. Items to be checked Possible malfunction Has the unit been installed ﬁrmly? The unit may drop, shake or emit noise. Have you done the refrigerant leakage test? It may cause insufﬁcient cooling (heating) capacity. Is heat insulation of pipeline sufﬁcient? It may cause condensation and water dripping. Is water drained well? It may cause condensation and water dripping. Is the voltage of power supply according to the voltage marked on the nameplate? It may cause malfunction or damaging the parts. Is electric wiring and pipeline installed correctly? It may cause malfunction or damaging the parts. Is the unit grounded securely? It may cause electric leakage. Does the power cord follow the speciﬁcation? It may cause malfunction or damaging the parts. Is there any obstruction in the air inlet and outlet? It may cause insufﬁcient cooling (heating) capacity. The dust and sundries caused during installation are removed? It may cause malfunction or damaging the parts. The gas valve and liquid valve of connection pipe are open completely? It may cause insufﬁcient cooling (heating) capacity. Test operation 1. Preparation of test operation ● The client approves the air conditioner. ● Specify the important notes for air conditioner to the client. 2. Method of test operation ● Put through the power, press ON/OFF button on the remote controller to start operation. ● Press MODE button to select AUTO, COOL, DRY, FAN and HEAT to check whether the operation is normal or not. ● If the ambient temperature is lower than 16℃ , the air conditioner can’t start cooling. 33 Configuration of connection pipe 1. Standard length of connection pipe ● 5m, 7.5m, 8m. 2. Min. length of connection pipe is 3m. 3. Max. length of connection pipe and max. high difference.

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. 34 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) 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 _ 350 350 Cooling only(g/m) Cooling and heating(g/m) 35 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. E: Expand the port ● Expand the port with expander. hard mold expander pipe pipe pipe cutter leaning uneven Note: ● "A" is different according to the diameter, please refer to the sheet below: burr B: Remove the burrs ● Remove the burrs with shaper and prevent the burrs from getting into the pipe. pipe shaper downwards A(mm) Outer diameter (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.
