    (b) where corrosive gas, such as sulfurous acid gas, is produced. Corroding copper pipes or soldered parts may result in refrigerant leakage. (c) near machinery emitting electromagnetic waves. Electromagnetic waves may disturb the operation of the control system and result in a malfunction of the equipment. (d) where flammable gases may leak, where there are carbon fiber or ignitable dust suspensions in the air, or where volatile liquids such as thinner or gasoline are handled.

    FOR THE FOLLOWING ITEMS, TAKE SPECIAL CARE DURING CONSTRUCTION AND CHECK AFTER INSTALLATION IS FINISHED. 1. Items to be checked after completion of work Items to be checked If not properly done, what is likely to occur Check Are the indoor and outdoor unit fixed The units may drop, vibrate or make noise.
  • Page 7 • Where the wall is not significantly tilted. • Where piping between indoor and outdoor units is possible within the allowable limit. (Refer to the installation manual of the outdoor unit.) • Install the indoor and outdoor units, power supply wiring and connecting wires at least 3.5ft. away from televisions or radios in order to prevent image interference or noise.
  • Page 8: Indoor Unit Installation

    4. INDOOR UNIT INSTALLATION • Use only accessories and parts which are of the designated specification when installing. CAUTION • Install so that the unit does not tilt to either side or forward. • Do not hold the unit by the horizontal flaps when lifting it. (This may damage the horizontal flaps.) (1) Open the piping through-hole.
  • Page 9 (4) Remove the front panel and the service lid. (Refer to Fig. 5) < How to remove the front panel and service lid > (1) Open the front panel to the point where it stops. (2) Push the axes on either side of the front panel towards the center of the main unit and remove. (You can also remove it by sliding the front panel either to the left or right and pulling it forward.) (3) Remove the screw from the service lid and pull the handle forward.
  • Page 10 • Remove the drain plug, the insulation tube, and the drain hose from the drain pan and replace. (Refer to Fig. 8) • Connect the local refrigerant piping ahead of time, matching it to the liquid pipe and gas pipe marks engraved on the installation panel (accessory) (1).

    (8) Connect the piping. (See “5.REFRIGERANT PIPING WORK” and Fig. 10) Refrigerant piping Secure with vinyl tape. Drain hose Transmission wiring and remote controller wiring Transmission wiring and remote controller A arrow view Refrigerant piping wiring Conduit Seal with putty corking material. Wrap the insulating tape overlapping at least half the width with each wrap.
  • Page 12 NOTE • Use a pipe cutter and flare suitable for the type of refrigerant. • To prevent dust, moisture or other foreign matter from infiltrating the tube, either pinch the end or cover it with tape. • Do not allow anything other than the designated refrigerant to get mixed into the refrigerant circuit, such as air, etc.
  • Page 13 CAUTION • CAUTION TO BE TAKEN WHEN BRAZING REFRIGERANT PIPING “Do not use flux when brazing refrigerant piping. Therefore, use the phosphor copper brazing filter metal (BCuP) which does not require flux.” (Flux has an extremely negative effect on refrigerant piping systems. For instance, if chlorine based flux is used, it will cause pipe corrosion.
