Cautions ■ 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. ■ In order to avoid injury, do not remove the fan guard of the outdoor unit. ■ To avoid oxygen deficiency, ventilate the room sufficiently if equipment with burner is used together with the air conditioner. ■ After a long use, check the unit stand and fitting for damage.
3. WHAT TO DO BEFORE OPERATION 7. OPERATION PROCEDURE This operation manual is for the following systems with standard control. Before initiating operation, contact your dealer for the operation that corresponds to your system type and mark. ■ Operation procedure varies according to the combination of outdoor unit and remote controller. Read "3. What to do before operation" on page 3.
Explanation of heating operation It may take longer to reach the set temperature for general heating operation than for cooling operation. The following operation is performed in order to prevent the heating capacity from dropping or cold air from blowing. For systems with cool/heat changeover remote control switch (See figure 9) 1 Select cooling operation mode with the cool/heat changeover remote control switch. 2 Press the operation mode selector button several times and select (program dry operation).
.4. 8. Setting the master remote controller ENERGY SAVING AND OPTIMUM OPERATION When the system is installed as shown in figure 4 (RXYCQ outdoor unit is connected to several indoor units). it is necessary to designate one of the remote controllers as the master remote controller. Observe the following precautions to ensure the system operates properly. ■ Only the master remote controller can select heating or cooling.
9.2. Maintenance before a long stop period (e.g. at Symptom 6: White mist comes out of a unit the end of the season) Symptom 6.1: Indoor unit ■ Let the indoor units run in fan only operation for about half a day in order to dry the interior of the units. Refer to "7.1. Cooling, heating, fan only, and automatic operation" on page 3 for details on fan only operation. ■ Turn off the power. The remote controller displays disappear. ■ Clean air filters and casings of indoor units.
". This is the case immediately after the main power supply switch is turned on and means that the remote controller is in normal condition. This continues for one minute. 2 If the system goes into fan only operation, but as soon as it goes into heating or cooling operation, the system stops ■ Check if air inlet or outlet of outdoor or indoor unit is not blocked by obstacles. Remove any obstacle and make it well-ventilated.
WARNING ■ Do not modify, disassemble, remove, reinstall or repair the unit yourself as incorrect dismantling or installation may cause an electric shock or fire. Contact your dealer. ■ ■ In case of accidental refrigerant leaks, make sure there are no naked flames. The refrigerant itself is entirely safe, non-toxic and non-combustible, but it will generate toxic gas when it accidentally leaks into a room where combustible air from fan heaters, gas cookers, etc. ... is present.
