1. The following should be always observed for safety WARNING Could lead to death, serious injury, etc. CAUTION Could lead to serious injury in particular environments when operated incorrectly. • After reading this manual, be sure to keep it together with the instruction manual in a handy place . WARNING Perform the installation securely referring to the installation manual. Do not install it yourself (customer).
2. Installation of Indoor, Outdoor Unit 1. Selection of the best location (unit: mm) Select location Install the air conditioner in the location that satisfies the following conditions. • The place shall easily bear a load exceeding four times the indoor unit’s weight. • The place shall be able to inspect the unit as the figure. • The place where the unit shall be leveled. • The place shall allow easy water drainage.(Suitable dimension “H” is necessary to get a slope to drain as figure.
2. Indoor unit installation ENGLISH ■ Installation of Unit Install the unit above the ceiling correctly. A CASE 1 B POSITION OF SUSPENSION BOLT D C E • Apply a joint-canvas between the unit and duct to absorb unnecessary vibration. • Apply a filter Accessory at air return hole.
• Select and mark the position for fixing bolts. • Drill the hole for set anchor on the face of ceiling. • Insert the set anchor and washer onto the suspension bolts for locking the suspension bolts on the ceiling. • Mount the suspension bolts to the set anchor firmly. • Secure the installation plates onto the suspension bolts (adjust level roughly) using nuts, washers and spring washers.
CAUTION Front of view • The unit must be horizontal or declined to the drain hose connected when finished installation. 1~3mm Ceiling CORRECT INCORRECT Drainage hole CAUTION FOR GRADIENT OF UNIT AND DRAIN PIPING Drainage hole Lay the drain hose with a downware inclination so water will drain out. Thermal insulator (Local supply) • Alway lay the drain with downward inclination (1/50 to 1/100). Prevent any upward flow or reverse flow in any part.
• Drill the piping hole with 70mm dia, hole core drill. • Piping hole should be slightly slant to the outdoor side. WALL Indoor Outdoor 5~7mm INSULATION, OTHERS THERMAL INSULATION Insulate the joint and tubes completely. All thermal insulation must comply with local requirement.
INSTALLATION OF REMOTE CONTROL BOX Install the remote control box and cord correctly. • Although the room temperature sensor is in the indoor unit, the remote control box should be installed in such places away from direct sunlight and high humidity. INSTALLATION OF THE REMOTE CONTROL BOX ROUTING OF THE REMOTE CONTROL CORD • Select places that is not splashed by water. • Select control position after receiving customer approval.
REFRIGERANT PIPING Perform the work according to the Service Manual or Installation Guide. • Use two spanners when connect the refrigerant pipe to the unit. • Make a bend with a radius as large as possible. • Perform air purge with R-22 or vacuum drying. • When piping work is finished, check all joints. Flared connection (Union) Use a seemliness tube Indoor Factory charged ■ Add refrigerant if piping is over 7.5m.
ELECTRICAL WIRING Perform the electrical wiring work according to the electrical wiring connection.
3. Connecting Pipes to the Indoor Unit 3-1. Preparation of Piping Main cause of gas leakage is defect in flaring work. Carry out correct flaring work in the following procedure. Copper tube Slanted Uneven Rough 90° 1) Cut the pipes and the cable. ■ Use the accessory piping kit or the pipes purchased locally. ■ Measure the distance between the indoor and the outdoor unit. ■ Cut the pipes a little longer than measured distance. ■ Cut the cable 1.5m longer than the pipe length.
6) Pipe bending 7) Brazing In refrigerant piping, bending (in particular, acute bending) must be minimized to reduce piping resistance. Bending is, however, necessary in some places by virtue of the installation position of devices auxiliary to the packaged air conditioner, or of the building structure, piping distance or finsishing appearance. If a more acute bend is required than that attainable by pipe bender, perform brazing using ready-made elbow.
4. Connecting Pipes to the Outdoor Unit 1) Connecting the pipes to the Outdoor unit 1. Align the center of the pipings and sufficiently tighten the flare nut with fingers. 2. Finally, tighten the flare nut with torque wrench until the wrench clicks. • When tightening the flare nut with torque wrench, ensure the direction for tightening follows the arrow on the wrench. Pipe size Liquid Side Gas Side Outdoor unit Torque 1/4" 1.8kg.m 3/8" 4.2kg.m 1/2" 5.5kg.m 1/2" 5.5kg.m 5/8" 6.6kg.m 3/4" 6.6kg.
6. Connecting Cables between Indoor Unit and Outdoor Unit ■ Connect the wires to the terminals on the control board individually according to the outdoor unit connection. • Ensure that the color of the wires of outdoor unit and the terminal No.
3) Connecting the cable to the Outdoor Unit 1. Remove the Cover control from the unit by loosening a screw. Connect the wires to the terminals on the control board individually as following. Outdoor unit Terminal block Cord Clamper Power supply cord 2. Secure the cable onto the control board with the holder (clamper). Over 5mm 3. Refix the cover control to the original position with the screw.
4) Form the pipings Seal a small opening around the pipings with gum type sealer. Drain hose Taping Pipings In case of the Outdoor unit being installed below position of the Indoor unit. Connecting cable Power supply cord 2. Tape the Pipings, drain hose and Connecting Cable from bottom to top. 3. Form the pipings gathered by taping along the exterior wall and fix it onto the wall by saddle or equivalent. Trap is required to prevent water from entering into electrical parts.
7. Air Purging of the Connecting Pipes and the Indoor Unit The air which contains moisture remaining in the refrigeration cycle may cause a malfunction on the compressor. 1. Confirm that both the liquid side valve and the gas side valve are set to the closed position. 2. After connecting the piping, check the joints for gas leakage with gas leak detector. 3. Remove the service port nut, and connect the gauge manifold and the vacuum pump to the service port by the charge hose. 4.
