As the installer or service person, it is an important part of your job to install or service the system so it operates safely and efficiently. For safe installation and trouble-free operation, you must: • Carefully read this instruction booklet before beginning. • Follow each installation or repair step exactly as shown. • Observe all local, state, and national electrical codes. • Pay close attention to all danger, warning, and caution notices given in this manual. Have it installed by a certified professional Always use a certified HVAC professional to install the split air conditioning system to prevent damage to the unit or injury to yourself. The vacuuming and charging of the line set is required during installation. Improper installation can result in water or refrigerant leakage, electrical shock, or fire. Be sure to check with your local codes as an electrician may be needed to install a dedicated power circuit. In Case of Improper Installation The manufacturer shall in no way be responsible for improper installation or maintenance service, including failure to follow the instructions in this document. 2 SPECIAL PRECAUTIONS When Wiring ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS SYSTEM. • Do not supply power to the unit until all wiring and tubing are completed or reconnected and checked. • Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram and these instructions when wiring. Improper connections and inadequate grounding can cause accidental injury or death. • Ground the unit following local electrical codes. • Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire hazard. When Installing... ...In a Ceiling or Wall Make sure the ceiling/wall is strong enough to hold the unit’s weight. It may be necessary to construct a strong wood or metal frame to provide added support. ...In a Room Properly insulate any tubing run inside a room to prevent “sweating” that can cause dripping and water damage to walls and floors. ...In Moist or Uneven Locations Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the outdoor unit. This prevents water damage and abnormal vibration. ...In an Area with High Winds Securely anchor the outdoor unit down with bolts and a metal frame. Provide a suitable air baffle. 3 SPECIAL PRECAUTIONS When Connecting Refrigerant Tubing • Keep all tubing runs as short as possible. • Use the flare method for connecting tubing. • Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before connecting them, then tighten the nut with a torque wrench for a leak-free connection. • Check carefully for leaks before starting the test run. When Servicing Turn the power OFF at the main circuit breaker panel before opening the unit to check or repair electrical parts and wiring. Keep your fingers and clothing away from any moving parts. Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have been left inside the unit being serviced. After installation, explain correct operation to the customer, using the operating manual. This air conditioner uses R410A. Please make note of these differences (1) Since the working pressure is 1.6 times higher than that of conventional refrigerant(R22) models, some of the piping and installation and service tools may be different. (2) Models that use refrigerant R410A have a different charging port thread diameter to prevent erroneous charging with conventional refrigerant(R22) and for safety. Therefore, check beforehand. [The charging port thread diameter for R410A is 1/2 threads per inch.] (3) Be careful that foreign matter (oil, water, etc.) does not enter the piping. Also, when storing the piping, securely seal the opening by pinching, taping, etc... (4) When charging the refrigerant, take into account the slight change in the composition of the gas and liquid phases, and always charge from the liquid phase side whose composition is stable. 4 INSTALLATION MANUAL For Room Air Conditioner (Split Wall-Mounted Type) Parts Installation Part # Name of part Qty 1 Installation Plate 1 2 Mounting Screw ST3.9 x 25-C-H 8 3 Clip Anchor 8 4 Refrigerant Pipe Liquid Side O 1/4” Gas Side <12000 Btu/h O 3/8” >12000Btu/h O 1/2” 5 Remote Controller 1 6 Seal 1 7 Drain Elbow 1 Anchor Bolts for Condensor Installation * The condensor unit should not be exposed to strong wind. * Fix the condensor unit with O 3/8” anchor bolts.
