1 Install a green/yellow insulated earthing wire (O1.6 mm, section 2 mm2 or greater): . If the earthing wire is too short, connect an extension lead, soldering the connec tion and wrapping it with insulating tape (do not bury the soldered connection) . Secure the earthing wire in position with staples 4 Dig a hole of the size indicated in the illustration opposite, drive the earthing electrode into position and cover the top of the electrode with the excavated soil. 3 Carefully check the installation, by measuring the earthing resistance with an earthing resistance tester. If the resistance is above the required level(Example:100.), drive the earthing electrode deeper into the ground or increase the number of earthing electrodes. 5 Connect the earthing wire to the earthing screw on the 6 air conditioner. Determine a suitable location for the earthing electrode: . In damp hard soil rather than loose sandy or gravel soil that has a higher earthing resistance . Away from underground structures or facilities, such as gas pipes, water pipes, telephone lines and underground cables . At least two meters away from a lightening conductor earthing electrode and its cable. 2 . The earthing wire for the telephone line cannot be used to earth the air conditioner. If the earthing electrode is installed in an area of heavy traffic, its wire must be connected securely. . Checking Correct Earthing 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 close to a neighbour. If it 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). Fixing the Unit in Position Position the outdoor unit so that the air flow is directed towards the outside, as indicated by the arrows on the top of the unit. 1 2 Attach the outdoor unit to the appropriate support using anchor bolts. Certainly fix up its rubber leg in order to prevent its vibration and noise. . If the outdoor unit is exposed to strong winds, install shield plates around the outdoor unit, so that the fan can operate correctly. 3 Carbon plastic Steel core PVC-insulated green/ yellow wire, 2mm2 x 3.5 m To earthing screw 50 cm 30 cm Model X Y MH040FX.A2B MH040FX.A2C MH18VF1X MH19VF1X 543 319 MH050FX.A2B MH050FX.A2C MH060FX.A3B MH070FX.A4B MH080FX.A4B 660 350 INSTALLING THE OUTDOOR UNIT ‘X’ mm ‘Y’ mm Rubber leg OUTDOOR UNIT INSTALLED ON THE WALL BY RACK - Ensure the wall will be able to suspend the weight of rack and outdoor unit; - Install the rack close to the colum as much as possible; - Install proper grommet in order to reduce noise and residual vibration transferred by outoor unit towards wall.

MH040FX.A2B/MH040FX.A2C / MH050FX.A2B/MH050FX.A2C / MH18VF1X/MH19VF1X 1 Check the piping connections. 2 Connect the charging hose of low pressure side of manifold gauge to the packed valve having a service port (MH040FX.A2B/MH040FX.A2C:3/8” service valve 2EA; MH050FX.A2B/MH050FX.A2C:3/8” service valve 1EA+1/2” service valve 1EA) as shown at the figure. 3 Open the valve of the low pressure side of manifold gauge counter-clockwise. 4 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 show -0.1MPa(-76cmHg) after about 10 minutes. This procedure is very important in order to avoid gas leak. - Turn off the vacuum pump - Remove the hose of the low pressure side of manifold gauge. 5 Set valve cork of both liquid side and gas side of packed valve to the open position. 6 Mount the valve stem nuts and the service port cap to the valve, and tighten them at the torque of 183kgf•cm with a torque wrench. 7 Check for gas leakage. - At this time, especially check for gas leakage from the 3-way valve’s stem nuts, and from the service port cap.. The outdoor unit is loaded with sufficient R410A refrigerant.Do not vent R-410A into atmosphere: it is a fluorinated greenhouse gas, covered by Kyoto Protocol, with a Global Warming Potential (GWP) = 1975. You should purge the air in the indoor unit and in the pipe. If air remains in the refrigerant pipes, it affects the compressor. It may cause reduction of cooling capacity and malfunction. Refrigerant for air purging is not charged in the outdoor unit. Use Vacuum Pump as seen in the picture. . When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor first before removing the connection pipe. If the refrige...
