Cautions ■ Do not operate the air conditioner when using a room fumigation - type insecticide. Failure to observe could cause the chemicals to become deposited in the unit, which could endanger the health of those who are hypersensitive to chemicals. ■ Do not use the air conditioner for other purposes. In order to avoid any quality deterioration, do not use the unit for cooling precision instruments, food, plants, animals or works of art.
6. OPERATION RANGE For systems with cool/heat changeover remote control switch 1 Operation range Select operation mode with the cool/heat changeover remote control switch as follows: Use the system in the following temperature and humidity ranges for safe and effective operation. RXQ5~18 RXYQ5~18 RXYQ5~18 RXYSQ4~6 –5~43°C DB –20~21°C DB –5~46°C DB –20~24°C DB(*) Cooling operation (figure 4.1) Heating operation (figure 4.2) Fan only operation (figure 4.
7.2. ■ Program dry operation The function of this program is to decrease the humidity in your room with minimal temperature decrease (minimal room cooling). ■ The micro computer automatically determines temperature and fan speed (cannot be set by the remote controller). ■ The system does not go into operation if the room temperature is low (<20°C). For systems without cool/heat changeover remote control switch 1 2 7.3. Refer to the operation manual of the remote controller.
.5. Precautions for group control system or two remote controller control system 9. MAINTENANCE This system provides two other control systems beside individual control (one remote controller controls one indoor unit) system. Confirm the following if your unit is of the following control system type. ■ Group control system One remote controller controls up to 16 indoor units. All indoor units are equally set.
Symptom 3: Fan operation is possible, but cooling and heating do not work. ■ Symptom 8.2: Indoor unit, outdoor unit ■ A continuous low hissing sound is heard when the system is in cooling or defrost operation. This is the sound of refrigerant gas flowing through both indoor and outdoor units. ■ A hissing sound which is heard at the start or immediately after stopping operation or defrost operation. This is the noise of refrigerant caused by flow stop or flow change.
■ Our network of dealers has access to a permanent stock of essential components in order to keep your air conditioner in operation as long as possible. Contact your dealer for more information. TEST , the unit number and the operation lamp If the display flash and the malfunction code appears. (See figure 6) 1 Inspection display 2 Indoor unit number in which a malfunction occurs 3 Operation lamp 4 Malfunction code ■ Measure: Notify your dealer and report the malfunction code.
12.2. Shortening of "maintenance cycle" and "replacement cycle" needs to be considered in following situations ■ The unit is used in locations where: 1. heat and humidity fluctuate out of the ordinary 2. power fluctuation is high (voltage, frequency, wave distortion, etc.) (The unit cannot be used if power fluctuation is outside the allowable range.) 3. bumps and vibrations are frequent 4. dust, salt, harmful gas or oil mist such as sulfurous acid and hydrogen sulfide may be present in the air 5.
