[. . . ] Safety Precautions (Carefully follow the precautions listed below because they are essential to guarantee the safety of the equipment. ) WARNING · Always disconnect the air conditioner from the power supply before servicing it or accessing its internal components. · Verify that installation and testing operations are performed by qualified personnel. · Verify that the air conditioner is not installed in an easily accessible area. GENERAL INFORMATION Carefully read the content of this manual before installing the air conditioner and store the manual in a safe place in order to be able to use it as reference after installation. conditioner is sold or transferred. For maximum safety, installers should always carefully read the following warnings. [. . . ] Fix the case with bolts to the side of the control box referring to the figure on the left side. In case of FJM outdoor unit, there is not enough space to fix all parts of transmitter. So you may use transmitter main PCB. Attach the transmitter main PCB to the case, then connect F1/F2 lines, R1/R2 lines which are upper controller communication cables and DC 12V power cables to the interface module referring to the figure on page 21. (Upper controller power should be off. ) You must check the position of dip switch on the transmitter main PCB and the main PCB of all of the indoor units. Assemble a cover of the outdoor unit and turn the power on. If you install a transmitter to the outdoor unit, every indoor unit which is connected to the outdoor unit can be controlled simultaneously. Each outdoor unit connected to the same centralized controller has its own transmitter. 3 Fix the case with bolts (Control Box in the outdoor unit) 4 MH060FXA3B/MH070FXA4B / MH080FXA4B Terminal side 5 6 7 Transmitter 8 7seg.

The corresponding accessories are not supplied with the air conditioner. Carbon plastic Steel core To earthing screw 1 2 Select an earthing electrode that complies with the specifications given in the illustration opposite. 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. The earthing wire for the telephone line cannot be used to earth the air conditioner. 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. Install a green/yellow insulated earthing wire (Ø1. 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 If the earthing electrode is installed in an area of heavy traffic, its wire must be connected securely. 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. Connect the earthing wire to the earthing screw on the air conditioner. PVC-insulated green/ yellow wire, 2mm2 x 3. 5 m 50 cm 30 cm 3 4 5 6 Fixing the Unit in Position `X' mm `Y' mm 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). Rubber leg 1 Y 319 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. Attach the outdoor unit to the appropriate support using anchor bolts. If the outdoor unit is exposed to strong winds, install shield plates around the outdoor unit, so that the fan can operate correctly. Certainly fix up its rubber leg in order to prevent its vibration and noise.
