Page 13: Outdoor Unit Installation
Outdoor unit installation The outdoor unit must be installed on a rigid and stable base to avoid any increase in the noise level and vibration, particularly if the outdoor unit is to be installed in a location exposed to strong winds or at a height, the unit must be fixed to an appropriate support(wall or ground). -
Page 14: Connecting The Cable
Connecting the cable Two electronic cables must be connected to the outdoor unit. The connection cord between indoor unit and outdoor unit. The power cable between outdoor unit and auxiliary circuit breaker. Be sure to run the power supply cable and the communication cable through electrical conduit as seen in the picture. - Page 15 Connecting the cable 1. RLA is based on AHRI 210/240 colling standard condition [Indoor temp. : 26.7 °C / 80 °F(DB) / 19.46 °C / 67 °F(WB), Outdoor temp. : 35 °C / 95 °F(DB)] NOTE 2. Voltage tolerance is ± 10 %. 3.

Page 20: Adding Refrigerant (R-410A)
Adding refrigerant (R-410A) The outdoor unit is loaded with sufficient refrigerant for the standard piping. Thus, refrigerant must be added if the piping is lengthened. This operation can only be performed by a qualified refrigeration specialist. For quantity of adding refrigerant, refer to page 19. -
Page 21: Connecting Up And Removing Air In The Circuit
Connecting up and removing air in the circuit When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor first before removing the connection pipe. If the refrigerant pipe is not properly connected and the compressor CAUTION works with the service valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle abnormally high. - Page 22 5. Purge the air from the system using vacuum pump for about 10 minutes. Close the valve of the low pressure side of manifold gauge clockwise. Make sure that pressure gauge shows -0.1 MPa(-76cmHg) after about 10 minutes. This procedure is very important to avoid a gas leak. Turn off the vacuum pump.

Page 24: Performing Leak Tests
Performing leak tests LEAK TEST WITH NITROGEN (before opening valves) In order to detect basic refrigerant leaks, before recreating the vacuum and A(Gas) recirculating the R-410A, it’s responsible of installer to pressurize the whole system with nitrogen (using a cylinder with pressure reducer) at a pressure above 40 bar (gauge). -
Page 25: Insulation
Insulation Once you have checked that there are no leaks in the system, you can insulate the piping and hose. 1. To avoid condensation problems, place an insulator around each refrigerant pipe. When insulate the pipe, be sure to overlap the insulation. The insulation has to be produced in full compliance of European NOTE regulation reg. -
