SYSVRF2 CEILING GB Ceiling/Floor VRF indoor unit INSTALLATION MANUAL
CONTENTS Strictly perform installation according to these installation instructions. Faulty installation may cause water leaks, electric shocks and fires. PAGE PRECAUTIONS.......................................................................................1 When installing the unit in a small room, take measures to keep the refrigerant concentration from exceeding allowable safety limits in the event of refrigerant leakage. Contact the place of purchase for more information.
2. If the refrigerant leaks during installation, ventilate the area immediately. Toxic gas may be produced if the refrigerant comes into contact with fire. INSTALLATION INFORMATION To install the unit properly, please read this Installation Manual. The temperature of the refrigerant circuit will be high, so please keep the interconnection cable away from the copper tube. The air conditioner must be installed by qualified personnel.
FOR ORIGINAL CONCRETE BRICKS CAUTION Install the hanging hook with expansible bolt into the concrete deep to 45~50mm to prevent loose. Never throw or strike the controller. Before installation, test the remote controller to determine its location in a reception range. Keep the remote controller at least 1 m away from the nearest TV set or stereo. (It is necessary to prevent image and noise interference.) Fig.

4.5 Material and size of the piping Bend the connecting pipe of a small wall thickness. Cut out a desired concave at the bending part of the insulating pipe. Then expose the pipe (cover it with tape after bending). To prevent collapsing or deformation. Bend the pipe at its widest radius. Use a bender on low radius pipes.

6. CAUTION CONNECTING THE DRAIN PIPE 1. Be sure to Install Current Leakage Protection Switch, Or electric shock may occur. 2. Power cord is to be selected according to national regulations. 3. An all-pole disconnection device which has at least a 3 mm separation distance between all poles and a residual current device (RCD) with a rating above 10 mA must be incorporated in the fixed wiring according to national regulations. 4.
Base on different purposes to setting the switch cords on PC panel of indoor electrical control box. Once finish the setting, please cut off the main power, and then input power again, otherwise, setting function could not work. 7.2 Indoor/outdoor unit signal wire Connect the wire according to their numbers. Incorrect connection may cause an error. Table: 8-1 ENC1 7.3 Wiring connection Seal the wiring connection with the insulation material, or the condensation will be caused.
