Indoor unit installation AA When deciding on the location of the air conditioner with the owner, the following restrictions must be taken into account. 1 Place the pattern sheet on the ceiling at the spot where you want to install the indoor unit. • Since the diagram is made of paper, it may shrink or stretch slightly due to temperature or humidity. For this reason, before drilling the holes maintain the correct dimensions between the markings. Concrete 2 Insert bolt anchors.
Purging the unit AA 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. NS035/052/071LDXEA Unscrew the pinch pipe at the end of each refrigerant pipe. • To prevent dirt or foreign objects from getting into the pipes during installation, do NOT remove the pinch pipe completely until you are ready to connect the piping.
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 1. Remove the pinch pipe on the pipes and connect the assembly pipes to each pipe, tightening the nuts, first manually and then with a torque wrench, a spanner applying the following torque. Refrigerant oil Torque wrench Spanner Flare nut Union Outer Diameter (D) Torque (N•m) ø6.
Cutting/Flaring the pipes 1. Make sure that you have the required tools available. (pipe cutter, reamer, flaring tool and pipe holder) 2. 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. Oblique Rough ENGLISH Pipe cutter Burr Pipe 3.
Performing leak test & insulation AA NS035/052/071LDXEA Leak test LEAK TEST WITH NITROGEN (before opening valves) In order to detect basic refrigerant leaks, before recreating the vacuum and recirculating 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). LEAK TEST WITH R-410A (after opening valves) Before opening valves, discharge all the nitrogen into the system and create vacuum.
Pipe size Liquid pipe Ø6.35 ~ Ø9.52 Ø12.7 ~ Ø19.05 Ø6.35 Ø9.52 Ø12.70 Ø15.88 Ø19.05 Gas pipe Insulation Type (Heating/Cooling) Standard [30°C, 85%] High humidity [30°C, over 85%] EPDM, NBR 9t 9t 13t 13t 13t 19t 19t Remarks ENGLISH Pipe Internal temperature is higher than 120°C 25t When installing insulation in places and conditions below, use the same insulation that is used for high humidity conditions.
Drainpipe and drain hose installation AA Drainpipe Connection Without the drain pump 1. Install horizontal drainpipe with a slope of 1/100 or more and fix it by hanger space of 1.0~1.5m. 2. Install U-trap at the end of the drainpipe to prevent a nasty smell to reach the indoor unit. 3. Do not install the drainpipe to upward position. It may cause water flow back to the unit. 1~1.5m Hanger Flexible hose Horizontal drainpipe more than 1/100 slope Ceiling With the drain pump 1.
Connecting the connection cord The indoor unit is powered by the outdoor unit by means of a H07 RN-F connection cable (or a more power model), with insulation in synthetic rubber and jacket in polychloroprene(neoprene), in accordance with the requirements of standard EN 60335-2-40. 1. Remove the screw on the electrical component box and remove the cover plate. 2. Route the connection cord through the side of the indoor unit and connect the cable to terminals; refer to the figure below. 3.
Adjusting air flow AA E. S. P(External Static Pressure) setting for phase control motor With its phase control motor, you can adjust the indoor unit fan speed depending on the installation condition. If the external static pressure is high so that the duct becomes longer or if the external static pressure is low so that the duct becomes shorter, adjust the fan speed by referring the following table. Static Pressure (mmAq) 0 2 2.
