  • Page 2: Safety Precautions

    Safety Precautions • Read these Safety Precautions carefully to ensure correct installation. • This manual classifies the precautions into DANGER, WARNING and CAUTION. Be sure to follow all the precautions below: they are all important for ensuring safety. DANGER ..Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. WARNING ..Failure to follow any of WARNING is likely to result in such grave consequences as death or serious injury.

    Safety Precautions WARNING • After connecting all wiring be sure to shape the cables so that they do not put undue stress on the electrical covers, panels or terminals. Install covers over the wires. Incomplete cover installation may cause terminal overheating, electrical shock, fire or equipment damage. • When installing or relocating the system, be sure to keep the refrigerant circuit free from all substances other than the specified refrigerant (R410A), such as air. (Any presence of air or other foreign substance in the refrigerant circuit causes an abnormal pressure rise which may result in rupture, resulting in injury.) • During pump-down, stop the compressor before removing the refrigerant piping. If the compressor is still running and the shut-off valve is open during pump-down, air will be sucked in when the refrigerant piping is removed, causing abnormally high pressure which could lead to equipment damage or and personal injury. • During installation, attach the refrigerant piping securely before running the compressor. If the refrigerant pipes are not attached and the shut-off valve is open when the compressor is run, air will be sucked in, causing abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury. • Install a leak circuit breaker, as required. If a leak circuit breaker is not installed, electric shock may result. • Be sure to install a ground fault circuit interrupter breaker. Failure to install a ground fault circuit interrupter breaker may result in electrically shocks or personal injury. CAUTION • Establish drain piping according to the instructions of this manual. Inadequate piping may cause water damage. • Note for installing the outdoor unit. (For heat pump model only.) In regions of the country where the outside temperature is at or below the freezing point, the drain may freeze. If so, it is recommended that an electric heater be installed in order to protect the drain from freezing. • Tighten the flare nut according to the specified torque. A torque wrench should be used. If the flare nut is tightened too much, the flare nut may crack over time and cause refrigerant leakage. • Do not touch the heat exchanger fins. Improper handling may result in injury. • Be very careful about product transportation. Some products use PP bands for packaging. Do not use any PP bands for a means of transportation. It is dangerous. Accessories Washer for Insulation Washer Screws for Clamp...

  • Page 4: Choosing An Installation Site

    Choosing an Installation Site • Before choosing the installation site, obtain user approval. Indoor unit CAUTION • When moving the unit during or after unpacking, make sure to lift it by holding its lifting lugs. Do not exert any pressure on other parts, especially the refrigerant piping, drain piping and flange parts. Wear protective gear (such as gloves) when installing the unit. • If you think the humidity inside the ceiling might exceed 86°F (30°C) and RH80%, reinforce the insulation on the unit body. Use glass wool or polyethylene foam as insulation so that the thickness is more than 0.4in (10mm) and fits inside the ceiling opening. • Optimum air distribution is ensured. • The air passage is not blocked. • Condensate can drain properly. • The ceiling is strong enough to bear the weight of the indoor unit. 12 (300) or more • A false ceiling does not seem to be at an incline. • Sufficient clearance for maintenance and servicing is ensured. Control box Maintenance space • Piping between the indoor and outdoor units is within the allowable limits. (Refer to the installation manual for the outdoor unit.) • The indoor unit, outdoor unit, power supply wiring and transmission wiring is at least 3.3ft (1m) away from televisions and radios. This prevents image interfer- ence and noise in electrical appliances. (Noise may be generated depending 13/16 (20) or more on the conditions under which the electric wave is generated, even if a 3.3ft Ceiling (1m) allowance is maintained.) ■...

    Choosing an Installation Site Wireless remote controller • Turn on all the fluorescent lamps in the room, if any, and find the site where remote controller signals are properly received by the indoor unit (within 13ft (4m)). Outdoor unit • For outdoor unit installation, see the installation manual supplied with the outdoor unit. Preparations before Installation ■ Relation of the unit to the suspension bolt positions. 24-7/16 (620) • Install the inspection opening on the control box side where 19-11/16 (500) maintenance and inspection of the control box are easy. Install the inspection opening also in the lower part of the unit. (unit : in (mm)) Suspension bolt pitch Ceiling ■...

  • Page 10: Installing The Duct

    CAUTION • Water accumulating in the drain piping can cause the drain to clog. • To keep the drain tube from sagging, space hanging wires every 3 (1) to 5ft (1.5m). • Use the drain hose and the metal clamp. Insert the drain hose fully into the drain socket and firmly tighten the metal clamp with the upper part of the tape on the hose end. Tighten the metal clamp until the screw head is less than 1/8 inch (4mm) from the hose. • The two areas below should be insulated because condensation may form there causing water to leak. • Drain piping passing indoors • Drain sockets Large sealing pad Clamp metal Referring the figure below, insulate the (accessory) (accessory) metal clamp and drain hose using the Clamp metal included large sealing pad.

  • Page 12: Connecting Electrical Wiring

    CAUTION • When doing the wiring, make sure the wiring is neat and does not cause the control box cover to stick up, then close the cover firmly. When attaching the control box cover, make sure you do not pinch any wires. • Outside the unit, separate the low voltage wiring (remote controller wiring) and high voltage wiring (ground wire and power supply wiring) at least 5in so that they do not pass through the same place together. Proximity may cause electrical interfer- ence, malfunctions, and breakage. [ PRECAUTION ] • See also the “Electrical Wiring Diagram Label” when wiring the unit for power supply. [ Connecting electrical wiring ] • Power supply wiring and ground wire Clamp (for fixing in place) Remove the control box cover. Terminal block (4P) (accessory) Next, pull the wires into the unit through the conduit and thread them through the insulation tube (accessory), then connect to the power Insulation tube (accessory) wiring terminal block (4P).
