Drain port zflexible installation Ceiling concealed Drain pump Height 7-25/32 in. (198mm) Drain pump built-in zcompact design Condensate lift-up to 33-15/32 in. (850mm). Wall concealed Max /32 in. (850mm) Drain hose is standard accessory zselectable with a wide range of static pressure By using DC fan motor, it is possible to change the static pressure range from 0 to 0.36in. WG (0 to 90Pa). The change of static pressure range is possible by remote controller. Static pressure range [in.wg (Pa)] 0.36(90) 0 Airflow rate [CFM (m 3 /h)] zfilter (Accessory) Filter : 2pcs. zair - intake Air intake direction can be selected to match the installation site.

5 - (01-02) - 222WIRED REMOTE CONTROLLER FEATURES Various timer setup available (ON/OFF/WEEKLY). Equipped with weekly timer as standard function. (Start/Stop function is twice per day for a week) When setting up the timer, start/stop and temperature setup can be changed. When a failure occurs, the error code is displayed. Error history.(last 16 error codes can be accessed.) The room temperature can be controlled by detecting the temperature accurately with Built-in thermo sensor. zhigh performance and compact size Individual control Thermo sensor Weekly timer Setback timer Wired remote controller zaccurate and comfortable Indoor temperature can be detected accurately by the inclusion of a thermo sensor in the body of the wired controller. Our system can correspond to various scenes. This wired remote controller and the optional remote sensor allows flexibility in sensor location, and suitable for all requirements. Sensor part Thermo sensor display Control part for changing the thermo sensor zbuilt-in timers Weekly timer Possible to set ON/OFF time to operate twice each day of the week. Easy-to-understand time bar display Setback timer Possible to set temperature for two time spans and for each day of the week. Example : setup screen (Set to Wednesday: 8:00 to 20:00.) 76 F (24 C) Screen after setup Example : setup screen (Set from Sunday to Saturday: 12:00 to 15:00, 28 C.) 84 F (28 C) time O'clock AM PM At "Weekly timer" + "Set back timer" setup time AM PM 84 F (28 C) 76 F (24 C) O'clock 76 F 84 F 76 F 24 C 28 C 24 C time AM PM O'clock zeasy-to-understand operation Timer area Operation area zsimple installation Components are compatible with standard switch boxes. Flat back surface allows equipment to be installed wherever it is needed. [Variable timer control] The operation/display sections are zoned according to time and operation, enabling variable programming to match application. European switch box JIS box

Incorrect settings can cause the indoor unit to malfunction. After the power is turned on, perform the Function Setting according to the installation conditions using the remote controller. The settings may be selected between the following two: Function Number or Setting Value. Settings will not be changed if invalid numbers or setting values are selected. PREPARATION Turn on the power. * Before turning on the power of the indoor units, make sure the piping air-tight test and vacuuming have been conducted. * Also check again to make sure no wiring mistakes were made before turning on the power.

If the setting value display changes or if - - is displayed when the flashing stops, the setting value has not been set correctly. (An invalid setting value may have been selected for the indoor unit.) (6) Repeat steps 2 to 5 to perform additional settings. Press the SET TEMP. buttons ( ) ( ) and FAN control button simultaneously again for more than 5 seconds to cancel the function setting mode. In addition, the function setting mode will be automatically canceled after 1 minute if no operation is performed. (7) After completing the Function Setting, be sure to turn off the power and turn it on again.! CAUTION After turning off the power, wait 30 seconds or more before turning it on again. The Function Setting will not become active unless the power is turned off then on again.
