Accessories English 3 English 4 [J] INSTALLATION INSTALLATION FOR COOLING FIXED INSTALLATION (see Figures 4 and 5) For fixed installation, a sleeve (1, Figure 4) should be installed through the wall, partition or window (Figure 5). The opening may be located in any convenient spot, providing it is within reach of the exhaust hose. Prepare an outlet hole 110 mm in diameter. Apply a waterproof sealant to the sieeve flange and install it in the opening. Insert the exhaust hose end into the fixed sleeve, make sure the connection is airtight (See Fig. 5). WARNING: Make sure the unit is level. Sleeve Window installation : | Partition installation , Wall installation Waterproof sealant Figure 4 с В A PROVISIONAL INSTALLATION This method of installation does not require a permanent opening in the room. The exhaust hose is inserted through the gap of a slightly opened door or window. This allows the unit to be easily moved from room to room and re-installed within minutes. Fit the window nozzle (4, Fig. 3) on the end of the exhaust hose and insert it through the opening of a door or a window. Use suction pads (3, Fig. 3) to hold the window in place. WARNING: Make sure the unit is level Figure 6 English 5 INSTALLATION FOR HEATING For heating operation the exhaust hose is not required; remove the hose and store it. Use the sleeve cover (2, Fig. 3) to close the wall opening. INSTALLATICN FOR "DRY" OPERATION In DRY operation (a mode giving priority to dehumidification while cooling), the exhaust hose removes hot and moist air to outdoors. The method of installation is the same as for cooling operation. INSTALLATION FOR DEHUMIDIFICATION In. this mode of operation the exhaust hose should be disconnected. Remove the exhaust hose and store it. During the entire dehumidification operation, the unit must be connected to a permanent drain by means of an extension tube (see Figure 7). NOTE: DURING A PROLONGED DEHUMIDIFICATION OPERATION EXPECT A RISE IN ROOM TEMPERATURE. CS << < | a Er 2 N À | — q NN SS ` Figure 7 ELECTRICAL CONNECTION Before plugging the unit in, check that: * The power supply and the fuse correspond to the value shown in the specification table. * The socket and the mains lead correspond to the power requirements of the air conditioner. * The socket fits the plug. * The socket is properly grounded.

English 6 [J OPERATION MODES OF OPERATION, FUNCTIONS AND FEATURES AN 0 + COOL Cools, dehumidifies and filters the room air. Maintains desired room temperature. HEAT Heats and filters the room air. Maintains desired room temperature. AUTO Automatically switches from COOLING to HEATING or from HEATING to COOLING, maintaining the desired temperature according to the room conditions. DRY Dehumidifies and softly cools the room. In DRY Mode, the air conditioner operates at an increased dehumidifying power. This function is recommended for use when temperature is rather low but the humidity is high. FAN Recirculates and filters the room air. Maintains constant air movementin the room. AUTO FAN The air conditioner automatically selects the FAN speed to suit the room temperature. At the start, the unit operates at high fan speed. As the room air approaches the desired temperature, the fan switches to a lower speed, for quieter operation. HOT KEEP In HEATING and in AUTO FAN, the fan will be turned off when the compressor is notin operation and will not be restarted, unless the indoor coil reaches adequate temperature. This HOT KEEP feature prevents uncomfortable cold air drafts; it is therefore recommended when the air conditioner is in HEATING mode. | FEEL Switches the temperature sensing point to the place where the remote control is located. (Generally the temperature sensor is located behind the intake grille of the air conditioner). This function is designed to provide a personalized environment by transmitting the temperature control command from the location next to you. The communication between the Remote Control and the unit is achieved via an infra-red signal. Therefore, in using this function, the Remote Control should always be aimed, without obstructions, at the air conditioner. Ohare tg avn ta banded ce snags hl ив СЫНЫ: English 7 English 8 © > © Real time control and display, automatically turns the air conditioner on and off according to the time of day setting, ensuring comfort conditions before returning home, without wasting electricity; it turns the air conditioner automatically off when sleeping. SLEEP Designed to create comfortable sleeping conditions. When in COOLING mode, the temperature rises one degree centigrade above the set-point after each consecutive hour, up to three hours, from the start of the mode. The temperature rise prevents the sense of over-cooling while sleeping (when your body is at rest). In HEATING mode the reverse occurs; the air conditioner lowers the temperature one degree every hour. When in SLEEP mode, the air conditioner will be automatically turned off after seven hours. The resultis a more comfortable and invigorating sleep, which leaves you feeling fresh and energetic in the morning. ROOM TEMPERATURE Measures and displays room temperature. FILTER INDICATION Filter indicator on the indoor unit display is turned on when the filter requires cleaning. After cleaning and reinstalling the filter, the system should be reset. BUZZER INDICATOR A soft buzzer will sound from the indoor unit display to indicate that a command sent by the remote control has been accepted and stored in the unit's memory. This feature may be easily canceled by the user from the display panel. ON-UNIT OPERATION The air conditioner can be turned on (for COOLING or HEATING) or off, directly from the indoor unit display panel, without the use of the remote control. 3-MIN. DELAYED RUN The compressor is protected by a three-minute delayed restart. MEMORY The microprocessor retains the last data entry, whether or not the unit is plugged in. Therefore, when the unit restarts after a power disruption or failure, it will resume operating in the same mode as before power disruption. LOCK Freezes the last operation setting on the remote control. When LOCK is activated, the remote control unit will not respond, so that the air conditioner cannot be operated by the remote control.
