PRECAUTIONS FOR SAFETY WARNING WARNINGS ABOUT INSTALLATION • Make sure to ask the qualified installation professional in electric work to install the air conditioner. If the air conditioner is inappropriate installed by yourself, it may cause water leak, electric shock, fire, and so on. • Be sure to connect ground wire. (grounding work) Incomplete grounding cause an electric shock. Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone wires. • If you install the indoor unit in a small room, take appropriate measures to prevent the refrigerant from exceeding the limit concentration even if it leaks. Consult the dealer from whom you purchased the air conditioner when you implement the measures. Accumulation of highly-concentrated refrigerant may cause an oxygen deficiency accident. • Check whether the piping work has been properly completed. When existing pipes are used and if they are not constructed properly, the refrigerant gas may leak. Contact the installation company and confirm that the piping work has been properly completed. For details of installation of the air conditioner, refer to the Installation Manual. Use tools and piping materials for R410 only. Failure to do so or improper installation may cause a burst of pipe, resulting in injury. WARNINGS ABOUT OPERATION • Cleaning of the air filter and other parts of the air filter involves dangerous work in high places, so be sure to have a service person do it. The self cleaning function of the air conditioner causes the internal fan to run at a high speed in some modes even while the air conditioner is not working, which may cause injury. Do not attempt it yourself. • Avoid cooling the room too strong or exposing the human body to cool breeze for a long time as it is bad for the health. • When you notice something abnormal with the air conditioner (smells like something scorching, poor cooling, etc.), immediately turn off the main switch and the circuit breaker, from the mains to stop the air conditioner, and contact the dealer. If the air conditioner is continuously operated with something abnormal, it may cause machine failure, electric shock, fire, and so on. WARNINGS ABOUT MOVEMENT AND REPAIR • When the air conditioner cannot cool or heat a room well, contact the dealer from whom you purchased the air conditioner as refrigerant leakage is considered as the cause. In the case of repair that requires refill of refrigerant, ask service personnel about details of the repair. The refrigerant used in the air conditioner is harmless. Generally, the refrigerant does not leak. However, if the refrigerant leaks in a room and a heater or stove burner in the room catches fire, it may generate toxic gas. When you ask service personnel for repairing refrigerant leakage, confirm that the leakage portion has been completely repaired. • Do not move or repair any unit by yourself. Since there is high voltage inside the unit, you may get electric shock when removing the cover and main unit. • Whenever the air conditioner needs repair, make sure to ask the dealer to do it. If it is repaired imperfectly, it may cause electric shock or fire. • When moving the air conditioner for re-installing at another place, ask the dealer to do it. If it is imperfectly installed, it may cause electric shock or fire. –2– EN 2-EN Toshiba XXXXXXX(X/X) +00EH99933501_00Ta.book Page 3 Tuesday, November 24, 2009 2:25 PM Owner’s Manual 4-way Air Discharge Cassette Type CAUTION CAUTIONS ABOUT INSTALLATION (Be sure to confirm the following cautions.) • Use an exclusive power circuit for the air conditioner. Use the rated voltage. • Certainly lay the drain hose for perfect draining. Bad drainage may cause flooding in the house and getting furniture wet. • Make sure to connect the air conditioner to an exclusive power supply of the rated voltage, otherwise the unit may break down or cause a fire. • Do not install the unit in a place where inflammable gas may leak. If inflammable gas accumulates around the unit, it may cause a fire. CAUTIONS ABOUT OPERATION • Carefully read this manual before starting the air conditioner. There are many important things to keep in mind for daily operation. • Do not use this air conditioner for special purpose such as preserving food, precision instruments, art objects, breeding animals, car, vessel, etc. • When the air conditioner is operated with a combustion appliance in the same place, be careful of ventilation to let fresh air enter the room. Poor ventilation causes oxygen shortage. • Do not place any combustion appliance in a place where it is directly exposed to the wind of air conditioner, otherwise it may cause imperfect combustion. • When the air conditioner is used in a closed room, be careful of sufficient ventilation of the room. Poor ventilation causes oxygen shortage. • Do not touch any switches with wet fingers. You may get an electric shock. • If the air conditioner won’t be used for a long time, turn off the main switch or the circuit breaker, for safety. • Do not put anything on the outdoor unit or step on it. If you do, the unit may topple over or you may get injured. • To make the air conditioner operate in its original performance, operate it within the range of the operating temperature specified in the instructions. Otherwise it may cause a malfunction, or water leak from the unit. • Do not expose the remote control to any liquid. 3-EN –3– Toshiba XXXXXXX(X/X) +00EH99933501_00Ta.book Page 4 Tuesday, November 24, 2009 2:25 PM Owner’s Manual 4-way Air Discharge Cassette Type 2. SYSTEM CHARACTERISTICS Air conditioner operating conditions For proper performance, operate the air conditioner under the following temperature conditions: Cooling operation Outdoor temperature : 23 °F to 109.4 °F (-5 °C to 43 °C) * Room temperature °F to 89.6 °F (21 °C to 32 °C) (Dry bulb temperature), : 69.8 59 °F to 75.2 °F (15 °C to 24 °C) (Wet bulb temperature) [CAUTION] Dry operation Heating operation Room relative humidity – less than 80 %. If the air conditioner operates in excess of this figure, condensation may occurs on the surface of the air conditioner. Outdoor temperature : 59 °F to 109.4 °F (15 °C to 43 °C) Room temperature : 62.6 °F to 89.6 °F (17 °C to 32 °C) Outdoor temperature : -4 °F to 59 °F (-20 °C to 15 °C) (Wet bulb temperature) Room temperature : 59 °F to 86 °F (15 °C to 30 °C) (Dry bulb temperature) *: The air conditioner can be operate when outside temperature is 5°F to 23°F (-15°C to -5°C). Installing wind baffle to the outdoor unit is necessary to operate the air conditioner in that outside temperature range. For further details, refer to the installation manual of the outdoor unit. If air conditioner is used outside of the above conditions, safety protection may work. 3 minute protection function There is a 3-minute time delay between compressor starts. Auto restart The unit will stop after a power failure. • The unit will restart automatically in the same operating mode as before the power failure when the power is restored. Fan operation Heating • When there is a call for heating, the fan will not start right away. There is a delay of approximately 5 minutes to ensure that the indoor heat exchanger warmed up. • When the room temperature reaches the set temperature, the fan will run at ultra low speed to avoid blowing cold air on the occupants in the space. Cooling When the room temperature reaches the set temperature, the fan will run at ultra low speed. Defrost When the unit is operating in the heating mode frost forms on the outdoor heat exchanger. When this occurs, defrost is initiated automatically. During the defrost period (2 to 10 minutes) both the indoor and outdoor units stop running. • A hissing noise might be heard when the defrost cycle is initiated. • During the defrosting operation, the defrosted water will be drained from the bottom plate of the outdoor unit. Heating capacity In the heating operation, the heat is absorbed from the outside and brought into the room. This way of heating is called heat pump system. When the outside temperature is too low, it is recommended to use another heating apparatus in combination with the air conditioner. Attention to snowfall and freeze on the outdoor unit • In snowy areas, the air inlet and air outlet of the outdoor unit are often covered with snow or frozen up. If snow or freeze on the outdoor unit is left as it is, it may cause machine failure or poor warming. • In cold areas, pay attention to the drain hose so that it perfectly drains water without water remaining inside for freeze prevention. If water freezes in the drain hose or inside the outdoor unit, it may cause machine failure or poor warming. –4– EN 4-EN Toshiba XXXXXXX(X/X) +00EH99933501_00Ta.book Page 5 Tuesday, November 24, 2009 2:25 PM Owner’s Manual 4-way Air Discharge Cassette Type 3. ENERGY SAVING RECOMMENDATIONS Select a comfortable set point and minimize adjusting it. • Clean the filter when ever the filter display is illuminated on remote control. • Keep doors and windows closed and open them only when necessary. • Use drapes, curtains, or shades to keep direct sun light from heating the room on very hot days. • Do not obstruct the return air grille. • Adjust the air flow direction for even air distribution in the room.

LOUVER DIRECTION For best cooling and heating performance, adjust the louvers appropriately. In cooling the louvers should be directed so that the air discharge is horizontal. In heating they should be directed to discharge towards the floor to prevent layers of hot air forming close to the ceiling. CAUTION Direct the louvers horizontally in cooling. If the louvers are pointed downward in cooling, condensation may form on the louvers and then drop to the floor. NOTE If the louvers are horizontal when in heating, the room temperature may be uneven with hot air near the ceiling. For cooling For heating Direct the louvers horizontally. Direct the louvers downward. • When the air conditioner is off, the louvers are directed horizontally automatically. • In the heating mode, at startup (the first 3 to 5 minutes), during defrost, and after the heating demand is satisfied (compressor turns off but fan runs at ultra low speed), the louvers are directed horizontally.
