Chff^j\bZe Abj Chg]blbhg^j (1) Insert the drain hose into the dent of heat insulation materials of indoor unit. (2) Insert the indoor/outdoor electric cord from backside of indoorunit, and pull it out on the front side, then connect them. (3) Coat the flaring seal face with refrigerant oil and connect pipes. Cover the connection part with heat insulation materials closely, and make sure fixing with adhesive tape.

When bending, be careful not to crash pipes. Connect beforehand the indoor/outdoor electric cable, and then pull out the connected to the heat insulation of connecting part specially. Hang surely the unit body onto the upper notches of the mounting plate. Move the body from side to verify its secure fixing. In order to fix the body onto the mounting plate, hold up the body aslant from the underside and then put it down perpendicularly. 8.5.7. When connecting the cord before installing the indoor unit Insert the cord from the back side of the unit, then pull it out on the front side. Loosen the screws and insert the cord ends fully into terminal block, then tighten the screws. Pull the cord slightly to make sure the cords have been properly inserted and tightened. After the cord connection, never fail to fasten the connected cord with the wiring cover. Note: when connecting the cord, confirm the terminal number of indoor and outdoor units carefully. If wiring is not correct, proper operation can not be carried out and will cause defect. 8.5.8. How to connect wiring to the terminals 1. For solid core wiring ( or F-cable )(Fig.1) (1) Cut the wire with a wire cutter or wire-cutting pliers, then strip the insulation to about 25mm of the exposed solid wire. (2) Using a screwdriver, remove the terminal screw (s) on the terminal board. (3) Using pliers, bend the solid wire to form a loop suitable for the terminal screw. (4) Shape the loop wire properly, place it on the terminal board and tighten securely with the terminal screw using a screw driver. 2. For strand wiring (Fig.2) (1) Cut the wire with a wire cutter or wire-cutting pliers, then strip the insulation to about 10mm of the exposed strand wiring. (2) Using a screwdriver, remove the terminal screw (s) on the terminal board. z 51 z
