Indoor unit installation It is recommended to install the refnet joint before installing the indoor unit. Place the pattern sheet on the ceiling at the spot where you want to install the indoor unit. Note Since the diagram is made of paper, it may shrink or stretch slightly due to temperature or humidity.
Purging the unit From factory the unit is supplied and set with a pre-charge of nitrogen gas. (insert gas) Therefore, all insert gas must be purged before connecting the assembly piping. Unscrew the pinch pipe at the end of each refrigerant pipe. Result: All inert gas escapes from the indoor unit.
Connecting the refrigerant pipe There are two refrigerant pipes of different diameters: A smaller one for the liquid refrigerant A larger one for the gas refrigerant The inside of copper pipe must be clean & has no dust. Remove the pinch pipe on the pipes and connect the assembly pipes Refrigerant oil to each pipe, tightening the nuts, first manually and then with a torque...
Cutting/Flaring the pipes Make sure that you have the required tools available. (pipe cutter, reamer, flaring tool and pipe holder) If you wish to shorten the pipes, cut it with a pipe cutter, taking care to ensure that the cut edge remains at a 90° angle with the side of the pipe. Refer to the illustrations below for examples of edges cut correctly and incorrectly.
Performing leak test & insulation Leak test LEAK TEST WITH NITROGEN (before opening valves) In order to detect basic refrigerant leaks, before recreating the vacuum and recir- culating the R-410A, it’s responsable of installer to pressurize the whole system with nitrogen (using a cylinder with pressure reducer) at a pressure above 30 bar (gauge).
Drainpipe and drain hose installation Flexible hose Care must be taken when installing the drainpipe and drain hose for the Drain pipe indoor unit so that condensate water is drained correctly outside. Fix the flexible hose to the drainpipe. The connection port of the flexible hose and PVC drainpipe must be fixed with PVC adhesives.
CAUTION Check that the indoor unit is level with the ceiling by using the leveler. If it is necessary to increase the height of the drainpipe, Install air ventilation to drain condensate water smoothly. install the drainpipe straightly within 11.8inch(300 mm)from the flexible hose port.
Assigning address to indoor unit Before installing the indoor unit, assign an address to the indoor unit according to the air conditioning system plan. The address of the indoor unit is assigned by adjusting MAIN(SW02) and RMC(SW04) rotary switches. The MAIN address is for communication between the indoor unit and the outdoor unit.
When installing the unit depending on the situation, you can fill up the air outlet(s) with one or more air blocking kits (not supplied). Then install the insulation to block air completely. Air blocking kits Technical Specification & Product feature Model CH070CAV1 CH105CAV CH140CAV Capacity (Cooling and 24,000/27,000Btu/h 36,000/38,000Btu/h 48,000/54,500Btu/h Heating)
Troubleshooting Detection of errors If an error occurs during the operation, one or more LED flickers and the operation is stopped except the LED. If you re-operate the air conditioner, it operates normally at first, then detect an error again. LED Display on the receiver &...
