4 Features and Benefits 1. Features and Benefits 1.1 FXLQ The floor standing unit can be installed quickly and easily in new or existing facilities in a variety of applications. Its compact design makes it suitable for perimeter zone air conditioning. FXLQ_MVJU9 - Floor Standing Models range from 0.6 to 2 Ton Stylish modern casing finished in ivory white Ideal for installation beneath a window thanks to its low height One of our slimmest indoor units (less than 9'') fits any interior design Requires minimal installation space Space-saving unit can be freestanding or wall-mounted Fitted with washable long-life filter Wide air discharge outlet distributes a comfortable airflow throughout the entire space Wall mounted installation facilitates cleaning beneath the unit where dust tends to accumulate 2 FXLQ-M / FXNQ-M

5 Features and Benefits 1.2 FXNQ The concealed floor units cover a wide range of capacities and can be built into counter in order to maintain the aesthetics of the room. FXNQ_MVJU9 - Concealed Floor Standing Models range from 0.6 to 2 Ton Ideal for installation beneath a window thanks to its low height One of our slimmest indoor units (less than 9'') fits any interior design - only the suction and discharge grilles are visible Requires minimal installation space Fitted with washable long-life filter The connecting port faces downward, eliminating the need to attach auxiliary piping FXLQ-M / FXNQ-M 3

SAFETY CONSIDERATIONS BEFORE INSTALLATION SELECTING INSTALLATION SITE PREPARATIONS BEFORE INSTALLATION INDOOR UNIT INSTALLATION REFRIGERANT PIPING WORK DRAIN PIPING WORK ELECTRIC WIRING WORK WIRING EXAMPLE AND HOW TO SET THE REMOTE CONTROLLER FIELD SETTING TEST OPERATION SAFETY CONSIDERATIONS Read these SAFETY CONSIDERATIONS for Installation carefully before installing air conditioning equipment. After completing the installation, make sure that the unit operates properly during the startup operation. Instruct the customer on how to operate and maintain the unit. Inform customers that they should store this Installation Manual with the Operation Manual for future reference. Always use a licensed installer or contractor to install this product. Improper installation can result in water or refrigerant Meanings of DANGER, WARNING, CAUTION, and NOTE Symbols: DANGER... Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. WARNING... Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. CAUTION... Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices. NOTE... Indicates situations that may result in equipment or property-damage accidents only. DANGER Refrigerant gas is heavier than air and replaces oxygen. A massive leak can lead to oxygen depletion, especially in basements, and an asphyxiation hazard could occur leading to serious injury or death. Do not ground units to water pipes, gas pipes, telephone wires, or lightning rods as incomplete grounding can cause a severe shock hazard resulting in severe injury or death. Additionally, grounding to gas pipes could cause a gas leak and potential explosion causing severe injury or death. If refrigerant gas leaks during installation, ventilate the area immediately. Refrigerant gas may produce this gas could cause severe injury or death. After completing the installation work, check that the refrigerant gas does not leak throughout the system. rials are present due to risk of explosions that can cause serious injury or death. Safely dispose all packing and transportation materials in accordance with federal/state/local laws or ordinances. Packing materials such as nails and other metal or wood parts, including plastic packing materials used for transportation may cause injuries or death by suffocation. WARNING tion work. Installation must be done in accordance with this installation manual. Improper installation When installing the unit in a small room, take measures to keep the refrigerant concentration from exceeding allowable safety limits. Excessive refrigerant leaks, in the event of an accident in a closed ambient - Install the air conditioner or heat pump on a foundation strong enough that it can withstand the weight result in the unit falling and causing injuries. Take into account strong winds, typhoons, or earthquakes when installing. Improper installation may result in the unit falling and causing accidents. Make sure that a separate power supply circuit is provided for this unit and that all electrical work is carried capacity or improper electrical construction may lead wires are used, and that no external forces act on the terminal connections or wires. Improper connections When wiring, position the wires so that the control box cover can be securely fastened. Improper positioning of the control box cover may result in electric shocks, Before touching electrical parts, turn off the unit. This equipment can be installed with a Ground-Fault Circuit Interrupter (GFCI). Although this is a recognized measure for additional protection, with the grounding system in North America, a dedicated GFCI is not necessary.

Do not change the setting of the protection devices. If the pressure switch, thermal switch, or other protection device is shorted and operated forcibly, or parts explosion may occur. CAUTION Do not allow children to play on or around the unit to prevent injury. Do not touch the refrigerant pipes during and immediately after operation as the refrigerant pipes may be hot or cold, depending on the condition of the refriger- sor, and other refrigerant cycle parts. Your hands may suffer burns or frostbite if you touch the refrigerant pipes. To avoid injury, give the pipes time to return to normal temperature or, if you must touch them, be sure to wear proper gloves. working around them. Install drain piping to proper drainage. Improper drain piping may result in water leakage and property damage. Insulate piping to prevent condensation. Be careful when transporting the product. Do not turn off the power supply immediately after stopping operation. Always wait for at least 5 minutes before turning off the power supply. Otherwise, water leakage may occur. Do not use a charging cylinder. Using a charging cylinder may cause the refrigerant to deteriorate. dry, and tight.

Do not install the air conditioner or heat pump in the following locations: (a) Where a mineral oil mist or oil spray or vapor is produced, for example, in a kitchen. Plastic parts may deteriorate and fall off or result in water leakage. (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.

34 Appendix 2. BEFORE INSTALLATION When moving the unit while removing it from the packing case, be sure to lift it by the four hanger brackets. Avoid putting any pressure on other parts especially the refrigerant piping. Be sure to check the type of R410A refrigerant to be used before installing the unit. (Using an incorrect refrigerant will prevent normal operation of the unit.) The accessories needed for installation must be retained in your custody until the installation work is completed. Do not discard them! Decide upon a line of transport. Leave the unit inside its packaging while moving, until reaching the installation site. Where unpacking is unavoidable, use a sling of soft material or protective plates together with a rope when lifting, to avoid damage or scratches to the unit. For the installation of an outdoor unit, refer to the installation manual attached to the outdoor unit. Do not install or operate the unit in rooms mentioned below. spray like in kitchens. (Plastic parts may deteriorate which could eventually cause the unit to fall out of place, or could lead to leaks.) Where corrosive gas like sulfurous gas exists.
