2. Consider environmental factors, such as typhoons and earthquakes, during installation. Improper installation may result in the equipment falling. If refrigerant leakage occurs, ventilate the area immediately. Toxic gas may be produced if the refrigerant comes into contact with fire. INSTALLATION INFORMATION To install the unit properly, please read this Installation Manual. The air conditioner must be installed by qualified personnel.

. INDOOR UNIT INSTALLATION Use the transparent hose filled with water to check the lever of the main body from the four sides or diagonal line direction. The lever indicator can check the lever from the four sides of the main body. (Refer to Fig.5-6) 5.1 Installation place (Refer to Fig.5-1, Fig.5-2, Fig.5-3 for specifications.
47(Panel) Unit: mm NOTE 570(Body) All illustrations in this manual are for reference only. They may be slightly different from the air conditioner you purchased (depend on model). The actual shape should be followed. 630(Body,include Electrical Box) 60 570(Body) 523(Hook-location) 647(Panel) 545(Hook-location) 5.3 Install The Panel CAUTION 280 Never put the panel face down on floor or against the wall, or on irregularly shaped objects. Fig.5-3 Drainage side A Never drop or strike it.
Modify the height of the indoor unit through the openings on the panel's four corners, if lifting the indoor unit and the drainage pipe is not influenced (Refer to Fig.5-14-right ). Keep fastening the screws under the panel hooks until the thickness of sealing sponges 1&2 between the body and the panel's outlet has been reduced to about 4-6mm. The edge of the panel should touch the ceiling well. (Refer to Fig.5-12) The fault described in Fig.
5 Panel Installation Instruction Sleeve 5.3 Connect the wiring between the indoor unit and the panel. Tighten belt 5.1 Fix the panel to the indoor unit and open the grill, as shown below. 5.4 Move the sleeve to the middle of the wirings and use the tighten belt to tie the sleeve ends tightly. Cut off the extra parts of the tighten belt. Sketch map of the sleeve bandage: 5.2 Put the indoor unit display board wiring and stepper motor wiring into the sleeve.
6. INSTALL THE CONNECTION PIPE Use frozen oil Check whether the height drop between the indoor unit and outdoor unit, the length of the refrigerant pipe, and the number of the bends meet the following requirements: ● The max height drop and length of refrigerant pipe depend on the outdoor unit. (If the height drop is more than 10000 mm position the outdoor unit above the indoor unit.) ● The number of bends must be fewer than 15.
90 °± 4 45 ° ±2 A The necessary filling amount of refrigerant ● The refrigerant volume to be added is calculated according to outdoor unit installation manual. Add refrigerant by measuring it on a scale. L: The length of the pipe ● Please record the quantity added and store it carefully for future maintenance. R0.4~0.8 Fig.7-2 Expel the air with a vacuum pump (Refer to Fig.7-4) (Please refer to its manual for how to use the manifold valve) Table.
5) When connecting the drainage pipe, do not drag the pipe and thus pull the main unit. To do so, arrange bearing points every 800 to 1000 mm to avoid bending the pipe (Refer to Fig.8-1 b). 7.2 Check The Leakage Check all the joints with the leak detector or soapy water. (Refer to Fig.7-6) D Check-point of indoor units B Check-point of the outdoor unit 6) When connecting a lengthened drainage pipe, apply protective tube to wrap the indoor part to connect it tightly.
8.2 Drainage Test 9.2 power wire connection Check that the drainage pipe is unhindered The indoor unit and outdoor unit should use separate power supplies, independent leakage protectors and an all-pole disconnection device. Newly built house should be tested before decorating the ceiling. Indoor units connecting to the same outdoor unit should use a uniform power supply, leakage protection devices and all-pole disconnection device. 1.

11 . TEST OPERATION According to the user’s requirements, install the remote controller frame where the remote controller’s signal can reach the indoor unit smoothly. CAUTION ● The protection function will delay the startup of compressor for 3 minutes if the unit is turned on immediately after powering on or restarting after shutting down. Test operation Set the air conditioner in "COOLING" mode with the remote controller. Then check the following points according to the "Owner’s Manual".
