SYSVRF2 FLOOR GB Floor VRF indoor unit INSTALLATION MANUAL
CONTENTS When installing the unit in a small room, take measures against to keep refrigerant concentration from exceeding allowable safety limits in the event of refrigerant leakage. Contact the place of purchase for more information. Excessive refrigerant in a closed ambient can lead to oxygen deficiency. PAGE PRECAUTIONS.......................................................................................1 INSTALLATION INFORMATION................................................................
Don't install the air conditioner in the following locations: If refrigerant leakage occurs, ventilate the area immediately. Toxic gas may be produced if the refrigerant comes into contact with fire. There is petrolatum existing. There is salty air surrounding (near the coast). After completing installation, make sure that refrigerant does not leak. There is caustic gas (the sulfide, for example) existing in the air (near a hot spring).
3. ATTACHED FITTINGS 4. INDOOR UNIT INSTALLATION 4.1 The units may be mounted vertically, provided that the correct clearances for positioning are maintained. (Refer to Fig. 4-1~Fig.4-5) Please check whether the following fittings are of full scope. If there are some spare fittings , please restore them carefully. ■ Version I Outline Installation manual 1 (This manual) Pipe insulation material 2 Heat insulation 1 Receive signal Signal receiver display board Mounting screw (ST3.

■ 5. INSTALL THE CONNECTING PIPE Put the unit onto the feet, and fix it by screws. CAUTION Do not let air, dust, or other impurities fall in the pipe system during the time of installation. The connecting pipe should not be installed until the indoor and outdoor units have been fixed already. Keep the connecting pipe dry, and do not let moisture in during installation. Fig.4-15 5.1 The Procedure of Connecting Pipes ■ 5.1.
Bend the pipe with thumb Bend Min-radius 100mm Fig. 5-2 Fig. 6-2 Fold Put as deep as possible (about 10cm) Make the ends straight Fig. 5-3 Downw ard declivity lower t han 1/100 2. Locate The Pipe 1) Drill a hole in the wall (suitable just for the size of the wall conduit, 90mm in general), then set on the fittings such as the wall conduit and its cover. 2) Bind the connecting pipe and the cables together tightly with binding tapes. Do not let air in, which will cause water leakage by condensation.

CAUTION 7.8 Network address set 1) Network address is set by communication of indoor and outdoor unit; the address is the same as indoor address, there is no need to set separately. The system together have 64units(0-63),everyone has only system addresscode,If two addresses are the same in one system , the abnormal operation will occur. Please switch off the power before setting,otherwise the unexpected error will occur. 7.
9. TEST OPERATION 8. ERROR CODE Table 8-1 Error Code 1 The test operation must be carried out after the entire installation has been completed. 2 Please confirm the following points before the test operation: Error Content FE No address when first time power on H0 M-Home not matched error(Reserved) E0 Mode conflict E1 Communication error of indoor and outdoor units E2 Error of indoor temp. sensor (T1) The ground wiring is connected correctly.
