Upper case (white) (b) Remote controller cords can be taken out upward only as shown below. Top (Cord take-out direction) ● Cut the remote controller lower case off at the top and thin section with a nipper, knife or other and remove burrs from the cut with a file or other. (c) Secure the remote controller lower case on the wall with 2 pieces of wood-screws. Top Lower case Lower case (brown) Bottom (d) Connect the remote controller cords with the terminal block. Make sure to align the terminal numbers on the indoor unit and the remote controller. Polarities are specified on the terminal block so that the unit will not be operated if the cords are connected improperly.

Refer to (c) for the setting of functions. 2) Couple the upper case with the lower case as they were. 3) Secure the remote controller cords on the wall or other using cord clamps. Embedded installation 1) Have a JIS box and remote controller cords (use shielding wires or twisted pair wires for extension) embedded in the wall in M4 round head screw x 2 pieces (Provided by customer) advance. Cautions for extension of remote controller cords Remote controller cords ● Make sure to use shielding wires only. • All models: 0.3 mm2 x 3 core wires [MVVS3C, JIS box (Provided by customer) products of Keihan Cables] Note (1) When the extension distance exceeds 100 m, change the wire size as follows: 100 ~ 200 m ... 0.50 mm2 ⳯ 3 core wires Adequate JIS box ~ 300 m ... 0.75 mm2 ⳯ 3 core wires ● JIS C 8336 Single switch box (without cover) ~ 400 m ... 1.25 mm2 ⳯ 3 core wires ● JIS C 8336 Medium size square outlet box and two-switch cover ~ 600 m ... 2.00 mm2 ⳯ 3 core wires with paint margin ● Make sure to ground one side only of the 2) Remove the upper case from the remote controller. shielding wire. 3) Secure the remote controller body on the JIS box with 2 pieces of M4 round head screw (provided by customer). 4) Connect remote controller cords with the remote controller. (Refer to the section regarding the exposed installation.) 6.5.3 Installation of outdoor unit OWARNING BE SURE TO READ THESE INSTRUCTIONS CAREFULLY BEFORE BEGINNING INSTALLATION. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD CAUSE SERIOUS INJURY OR DEATH, EQUIPMENT MALFUNCTION AND/ OR PROPERTY DAMAGE. Models : FDC208~508 series (1) Installation (a) Accessories Confirm accessories shown below are attached in the bag with this installation manual. 1) “Edging” for protection of electric wires from opening edge. (b) Selection of installation location Select the installation location after obtaining the approval of customer. 1) The place where the foundation can bear the weight of Outdoor unit. 2) The place where there is no concern about leakage of combustible gas. 3) The place where it is not stuffy. 4) The place where free from thermal radiation of other thermal source. 5) The place where flow of drain is allowed. 6) The place where noise and hot air blast do not trouble neighboring houses. 7) The place where there is no obstruction of wind at the intake air port and discharge air port. 261 FDTN-H (5) Electrical wiring ™ This air conditioning system should be notificated to supply authority before connection to power supply system. (a) Selection of size of power supply and interconnecting wires. OIMPORTANT ● Electric wiring work should be conducted only by authorized personnel. ● Use copper conductor only. ● Power source wires and Interconnecting wires shall not be lighter than polychloroprene sheathed flexible cord (design HO5RN-F IEC 57). ● Do not connect more than three wires to the terminal block. ● Use round type crimped terminal lugs with insulated grip on the end of the wires. ¡ Select wire sizes and circuit protection from Table 2.
