• Do not install the air conditioner in the following locations: 1. Where there is a high concentration of mineral oil spray or vapour (e.g. a kitchen). Plastic parts will deteriorate, parts may fall off and water leakage could result. 2. Where corrosive gas, such as sulphurous acid gas, is produced. Corroding of copper pipes or soldered parts may result in refrigerant leakage. 3. Near machinery emitting electromagnetic radiation.
Is something blocking the air outlet or inlet of either the indoor or outdoor units? It may result in insufficient cooling. Are refrigerant piping length and additional refrigerant charge noted down? The refrigerant charge in the system is not clear. *300 300 or or more more Control box Maintenance Maintenance space space Also review the “SAFETY PRECAUTIONS”.
4. PREPARATIONS BEFORE INSTALLATION (1) Confirm the positional relationship between the unit and suspension bolts. (Refer to Fig. 2) • Install the inspection opening on the control box side where maintenance and inspection of the control box and drain pump are easy. Install the inspection opening also in the lower part of the unit. 620 Air inlet A Air outlet (length : mm) Drain pump B (Suspension bolt pitch) 500 Suspension bolt pitch (3) Open the installation hole.
(3) Main unit Force Attach the filter to the main unit while pushing down on the bends. Filter Level Force Vinyl tube (4) Tighten the upper nut. 6. In case of bottom side 5. In case of back side INDOOR UNIT INSTALLATION As for the parts to be used for installation work, be sure to use the provided accessories and specified parts designated by our company. (1) Install the indoor unit temporarily. • Attach the hanger bracket to the suspension bolt.
• Refer to Table 1 for tightening torque. Table 1 33 – 39 N·m 12.8 – 13.2 φ 12.7 50 – 60 N·m 16.2 – 16.6 φ 15.9 63 – 75 N·m 19.3 – 19.7 0 φ 9.5 R0.4-0.8 A 8.7 – 9.1 0 15 – 17 N·m 0 φ 6.4 Flare shape 45 Ⳳ2 Flare dimension A (mm) 0 Tightening torque 90 Ⳳ2 Pipe size CAUTION Overtightening may damage the flare and cause leaks. Be careful for oil not to adhere to any portions other than a flare part. If oil adhere to resin parts etc., there is a possibility of damaging by deterioration.
7. DRAIN PIPING WORK CAUTION • Make sure all water is out before making the duct connection. (1) Install the drain piping. (accessory) Tape Drain socket Large sealing pad (5) (accessory) Metal clamp (1) (accessory) Metal clamp (1) Drain hose (2) (accessory) Fig. 11 ≤4mm Fig. 12 PRECAUTIONS FOR DRAIN RAISING PIPE • Make sure the drain raising pipe height is no higher than 600mm. • Place the drain raising pipe vertically and make sure it is no further than 300mm from the unit. (Refer to Fig.
1. Remove the control box lid. Connect the remote controller and power supply (single-phase, 50 Hz 220-240 V or single-phase, 60Hz 220V) respectively to the terminal block and securely connect the earth also (as shown in the figure below). CAUTION Securely clamp the cables with the clamps (9)(10) offered as accessories as shown in Fig. 17 so that tension will not be applied on the cable connection areas. 2. Confirm that the control box lid is closed before turning on the power. 3. Remove the inspection lid.
9. ELECTRIC WIRING WORK • The length of the transmission wiring and remote controller wiring are as follows. 9-1 GENERAL INSTRUCTIONS Length of the transmission wiring and remote controller wiring • Shut off the power before doing any work. • All field supplied parts and materials, electric works must conform to local codes. • Use copper wire only. • See also the “Wiring Diagram plate” attached to the control box lid when laying electrical wiring.
10. WIRING EXAMPLE 10-1 HOW TO CONNECT WIRINGS • Wire only after removing the control box lid as shown in Fig. 17, refering to view A. Control box lid Power supply wiring Earth wire Wiring Diagram (Rear) view A [ PRECAUTIONS ] • Refer to the “REMOTE CONTROLLER INSTALLATION MANUAL” on how to install and lay the wiring for the remote controller. • See also the “Wiring Diagram plate” attached to the control box lid when laying electrical wiring.
• Remote controller and transmission wiring Pull the wires into the unit through the wiring through hole and connect to the terminal block (6P). Be sure to put the part of the sheathed vinyl into the control box. Precautions when laying power supply wiring • Wiring of different thicknesses cannot be connected to the power supply wiring terminal block. (Slack in the power supply wiring may cause abnormal heat.
10-2 CONTROL BY 2 REMOTE CONTROLLERS (Controlling 1 indoor unit by 2 remote controllers) No. 3 system When including BS unit Power supply single phase 50Hz 220-240V or single phase 60Hz 220V • When using 2 remote controllers, one must be set to “MAIN” and the other to “SUB”.
[ PRECAUTIONS ] • Crossover wiring is needed when using group control and 2 remote controllers at the same time. • Connect the indoor unit at the end of the crossover wire (P1, P2) to remote controller 2 (SUB). Indoor unit 1 Indoor unit 2 Max. No. of indoor units 11-1 SETTING THE STATIC PRESSURE SELECTION • Select the SECOND CODE NO. for the resistance of the connected duct. (The SECOND CODE NO. is set to “01” when shipped.) • See the technical documentation for details.
11-4 SETTINGS FOR SEPARATELY SOLD ACCESSORIES • See the instruction manuals included with separately sold accessories for the necessary settings. When using a wireless remote controller • A wireless remote controller address needs to be set when using a wireless remote controller. See the installation manual included with the wireless remote controller for details on how to make the settings. (3) Perform a test run according to the outdoor unit’s installation manual.
