Connect the drain hose to the drain outlet on the indoor unit, and tighten it with the clap.,,, When electric wiring work is finished, check drainage flow during COOL running, explained in "Test operation" on page 16. Precautions 5 ELECTRC WRNG WORK nstall the drain raising pipes at a height of less than 0.9 in/530. nstall the drain raising pipes at a right angle to the indoor unit and no ore than 11.8 in/300 fro the unit. To prevent air bubbles, install the drain hose level or slightly tilted up (_<3in/75 ). The incline of drain hose should be 3 in/75 or less so that the drain socket does not have to withstand additional force. To ensure a downward slope of 1:100, install hanging bars every 3.3ft/1 to 4.9ft / 1.5. When unifying ultiple drain pipes, install the pipes as shown in figure below. Select converging drain pipes whose gauge is suitable for the operating capacity of the unit. [] 6 rq--rr7 f - _-_-_-_ Unit: General [] instructions All field wiring and coponents ust be installed by a licensed electrician and ust coply with relevant regulations. [] Use copper wire only. [] Follow the 'Wiring diagra' attached to the unit body to wire the outdoor unit, indoor units and the reote controller. A circuit breaker capable of shutting down power supply to the entire syste ust be installed. Note that the operation will restart autoatically if the ain power supply is turned off and then turned back on again. [] Be sure to ground the air conditioner. Do not connect the ground wire to gas pipes, water pipes, lightning rods, or telephone ground wires. Gas pipes: ight cause explosions or fire if gas leaks. Water pipes: no grounding effect if hard vinyl piping is used. Telephone ground wires or lightning rods: ight cause abnorally highelectric potential in the ground during lightning stors.

Do not connect wires of different gauges to the sae power supply terinal. (Looseness in the connection ay cause overheating.) When connecting wires of the sae gauge, connect the according to the figure. Use the specified electric wire. Connect the wire securely to the terinal, Lock the wire down without applying excessive force to the terinal. (Tightening torque: 1.31N. 10%). Cover Bolts When attaching the control box lid, ake sure not to pinch any wires. After all wiring connections are done, fill in any gaps in the casing wiring holes with putty or insulation aterial (field supply) thus to prevent sall anials or dirt fro entering the unit fro outside and causing short circuits in the control box. Do not connect wires of different gauge to the sae grounding terinal. Looseness in the connection ay deteriorate the protection. Use only specified wires and tightly connect wires to the terinals. Be careful that wires do not place external stress on the terinals. Keep wiring in neat order so that they do not obstruct other equipent such as popping open the service cover. Make sure the cover closes tight. ncoplete connections could result in overheating, and in the worst case, electric shock or fire. 16
