User manual HAIER HSU-22HRA03/R2

[. . . ] In the case of fixing the remote controller on a wall, place where the indoor unit can receive signals when the fluorescent lamps in the room are lightened. Place, which is less affected by rain or direct sunlight and is sufficiently ventilated. Place, possible to bear the unit, where vibration and noise are not increased. Place, where discharged wind and noise do not cause a nuisance to the neighbors. Place, where a distance marked is available as illustrated in the above figure. Power Source Before inserting power plug into receptacle, check the voltage without fail. [. . . ] 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. Pipe Diameter Liquid side 6. 35mm(1/4") Fastening torque 18N. m 42N. m 55N. m Spanner Gas side 9. 52mm(3/8") Torque wrench Gas side 12. 7mm(1/2") Be careful that matters, such as wastes of sands, etc. 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. Outdoor unit Outdoor unit B A Indoor unit B A Indoor unit A B Oil trap Indoor unit Outdoor unit CAUTION Max. Elevation: Amax=10m In case the elevation A is more than 5m, oil trap shoud be installed every 5~7m In case A is more than 5m Max. Length: Bmax=15m In case the pipe length B is more than 5m, the refrigerant should be charged, according to 20 g/m. 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. Drain elbow Drain hose 6 Outdoor unit 5. Purging Method: Push the air out of the indoor unit and piping as followes: (1) Remove the valve cap on 2-way valve in outdoor unit. (2) Loosen by 1/2 turn the flare nut of gas pipe, which is conneted to 3-way valve. (3) Loosen 2-way valve by 90o using hexagon wrench, and after approx. Gas comes out through flare nut on wide pipe. If no gas is discharged, tighten flare nut with specified torque. (4) Open 2-way and 3-way valves using specified torque. (5) Tighten the caps on the valves with specified torque. 2-way valve 6. 35mm(1/4") 3-way valve 9. 52mm(3/8") HSU-07HRA03/R2 HSU-09HRA03/R2 HSU-12HRA03/R2 HSU-18HRA03/R2 2-way valve 6. 35mm(1/4") 3-way valve 12. 7mm(1/2") Tighten torque N. m Valve rod Valve cap 7-9 20-25 HSU-22HRA03/R2 When connecting pipe exceeds 5 meters, 16g refrigerant shall be added per exceeding meter. Charge according to the following list. Piping length Additional amount 5m No need 7m 32g 10m 80g Note: When extending piping, air inside piping shall be removed by using external refrigerant gas, charge according to the following list. Brand new outdoor unit is charged 50g or 80g (only for 22k ) more refrigerant than regulated weight. Only for first installation, this extra 50g or 80g (only for 22k ) can be used to purge air in pipes. During this procedure, 50g or 80g (only for 22k )refrigerant will be discharged in piping.
