Note 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 Insert 2 Insert bolt anchors, use existing ceiling supports or construct a suitable support as shown in figure. Hole in anchor Hole in plug 3 Install the suspension bolts depending on the ceiling type. Ensure that the ceiling is strong enough to support the weight of the indoor unit. Before hanging the unit, test the strength of each attached suspension bolt. If the length of suspension bolt is more than 1. 5m, it is required to prevent vibration. If this is not possible, create an opening on the false ceiling in order to be able to use it to perform the required operations on the indoor unit. Suspension bolt( 3/8" or M10) Ceiling support 4 Screw eight nuts to the suspension bolts making space for hanging the indoor unit. You must install the suspension bolts more than four when installing the indoor unit. 5 Hang the indoor unit to the suspension bolts between two nuts. Note Piping must be laid and connected inside the ceiling when suspending the unit. There are some examples of correctly and incorrectly cut edges below. Oblique Rough Burr 2 3 4 To prevent a gas leak, remove all burrs at the cut edge of the pipe using a reamer. Carry out flaring work using flaring tool as shown below.

E-11 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 recirculating the R410A, it's responsible of installer to pressurize the whole system with nitrogen (using a pressure regulator) at a pressure above 4. 1MPa (gauge). LEAK TEST WITH R410A (after opening valves) Before opening valves, discharge all the nitrogen into the system and create vacuum. After opening valves check leaks using a leak detector for refrigerant R410A. Leak check Discharge all the nitrogen to create a vacuum and charge the system. Insulation Once you have checked that there are no leaks in the system, you can insulate the piping and hose. No gap 1 To avoid condensation problems, place T13. 0 or thicker Acrylonitrile Butadien Rubber separately around each refrigerant pipe. Note Always make the seam of pipes face upwards. NBR(T13. 0 or thicker) 2 Insulation cover pipe Insulation pipe Indoor unit Wind insulating tape around the pipes and drain hose avoiding to compress the insulation too much. 3 Finish wrapping insulating tape around the rest of the pipes leading to the outdoor unit. Be sure to overlap the insulation Must fit tightly against body without any gap. 4 The pipes and electrical cables connecting the indoor unit with the outdoor unit must be fixed to the wall with suitable ducts. All refrigerant connection must be accessible, in order to permit either unit maintenance or removing it completely. E-12 5 Select the insulation of the refrigerant pipe. Insulate the gas side and liquid side pipe referring to the thickness according to the pipe size. Indoor temperature of 30°C and humidity of 85% is the standard condition. If install in a high humidity condition, use one grade thicker insulator by referring to the table below. If installing in an unfavorable conditions, use thicker one. Insulation's heat-resistance temperature should be more than 120.

The drain hose can be installed to the right or left side of the base pan. 1 Unscrew the 4 tapped screws to remove the cover of the drain hose connection port. Drain hose connection port 2 Insert the flexible hose to the drain hose port. Note Fix the flexible hose to the indoor unit with the supplied cable clamp securely.
