CONTENTS Group Remote Controller (UTB-*D*) INSTALLATION INSTRUCTION SHEET (PART NO. 9374707034) For authorized service personnel only. WARNING This mark indicates procedures which, if improperly performed, might lead to the death or serious injury of the user. G For the air conditioner to operate satisfactorily, install it as outlined in this installation instruction sheet. G Do not turn on the power until all installation work is complete. G Installation work must be performed in accordance with national wiring standards by authorized personnel only. Let the customer keep this installation instruction sheet because it is needed when the air conditioner or remote controller is serviced or moved. G Check the condition of the installation stand for damage. G Ensure that any electronic equipment is at least one meter away from the controller. G Avoid installing the controller near a fireplace or other heating apparatus. G When installing the controller, take precautions to prevent access by infants. G Do not use inflammable gases near the controller.

remove the two screws indicated in the right figure and then, re- move the front case of the remote controller. NOTES When installing the remote controller, remove the connector from the front case. The wires may break if the connector is not removed and the front case hangs down. When installing the front case, connect the connector to the front case. G When remote controller cord exposed 1) Make two horizontal or two vertical holes in the mounting surface (wall, etc.) to install the remote controller. (Fig. 2) 2) Use a tool to cut away the thin area on the upper center of the front case (indicated by in Fig. 1). 3) Connect the remote controller cord to the remote controller terminal board specified in Fig. 2. 4) Wrap the connector and remote controller cords with vinyl tape or some other type of insulation as shown in Fig. 2. 5) Clamp the remote controller cord with the binder as shown in Fig. 2. 6) Cut off the excess binder. 7) Install the rear case to the wall, etc., with two screws (ø4 × 16). (Fig. 3) NOTES Step 4) will be noticed by customers, so do it with particular care. 3. INSTALLING THE REMOTE CONTROLLER CAUTION • Do not touch the group remote controller Circuit board and Circuit board parts directly with your hands. • When working with the wiring, be careful not to scratch or damage the wires.
