2. Installation location 2.1. Outline dimensions (Indoor unit) (Fig. 2-1) Select a proper position allowing the following clearances for installation and main- tenance. (mm) Models 30, 36, 42, 48 1900 Min. 300 Min. 100 Min. 1000 Min. 5 * Do not place any objects within 1000 mm of the air outlet. Warning: Mount the indoor unit on a ceiling strong enough to withstand the weight of the unit.
3. Installing the indoor unit 3.3. Mounting the tip-over prevention bracket (Fig. 3-3) (mm) • Select one of the following mounting methods, depending on the height of the frieze inside the wall above the floor. • In the case of a light steel bed, a frieze is generally not used, so the bracket should be mounted to one of the supports or pillars (obtain the screws locally).

4. Installing the refrigerant piping 4.2. Indoor unit (Fig. 4-1) 45° ±2° • When commercially available copper pipes are used, wrap liquid and gas pipes with commercially available insulation materials (heat-resistant to 100 °C or more, thickness of 12 mm or more). • The indoor parts of the drain pipe should be wrapped with polyethylene foam insula- tion materials (specific gravity of 0.03, thickness of 9 mm or more).
4. Installing the refrigerant piping Refrigerant piping connection (Fig. 4-4) 1. Remove the screw from the air intake grill handle and then remove the air intake grill by pulling it up and forward. 2. Remove the tapping screw that holds the pipe support in place and then remove the pipe support.
6. Electrical work 6.1. Electric wiring (Fig. 6-1) 1. Remove the tapping screws a and then remove the electrical equipment cover 2. Connect the electric wires securely to the corresponding terminals. 3. Fasten the connecting wiring with the bands c. • Always ground (the ground wire diameter must be 1.6 mm or more). •...

Function setting on the unit (Fig. 6-2) Mode number Changing the power voltage setting Setting number • Be sure to change the power voltage setting depending on the voltage used. Refrigerant address 1 Go to the function setting mode. Unit number Switch ON/OFF the controller.
7. Test run 7.1. Before test run ► After completing installation and the wiring and piping of the indoor and ► Use a 500-volt megohmmeter to check that the resistance between the power outdoor units, check for refrigerant leakage, looseness in the power supply supply terminals and ground is at least 1.0 MΩ. or control wiring, wrong polarity, and no disconnection of one phase in the Do not carry out this test on the control wiring (low voltage circuit) terminals. supply. Warning: Do not use the air conditioner if the insulation resistance is less than 1.0 MΩ. 7.2. Test run A ON/OFF button B Test run display The following 2 methods are available. C Indoor liquid line 7.2.1. Using wired controller (Fig. 7-1) temperature display 1 Turn on the power at least 12 hours before the test run.

8. Easy maintenance function Display example (Comp discharge temperature 64 °C) By using the maintenance mode, you can display many types of maintenance data on the controller such as the heat exchanger temperature of the indoor and outdoor units and compressor current consumption. This function can be used whether the air conditioner is operating or not. During air conditioner operation, data can be checked during either normal operation or maintenance mode stable operation.
