[. . . ] (For the complete information, read the installation manual for air conditioner outdoor units. ) 3) Use clean, new pipe fittings when connecting the connection pipe. Install the pipe carefully avoiding mixing of moisture and rubbish. 2. Wiring 1) The remote control switch cannot be connected to both of the two indoor units (main and sub units). Connect it only to the indoor unit that will become the main indoor unit (Unit A). [. . . ] Fix the branch pipes onto a wall in a ceiling or onto a column. Provide a straight pipe longer than 500mm in length as the main piping of the branches. In parentheses ( ) are wall thickness [unit: mm] Model SH1100AT-E SH1400AT-E (RAV-) Gas Main piping Ø15. 9 (1. 0) side Branch piping Ø 12. 7 (0. 8) Ø 15. 9 (1. 0) Main piping Ø 9. 5 (0. 8) Liquid side Branch piping Ø 6. 4 (0. 8) Ø 9. 5 (0. 8) Pipe side Inclination Horizontal Inclination Air Purging For the complete information, read the installation instructions for outdoor units of air conditioner. Purge air using a vacuum pump. Additional Refrigerant Amount Cautions Be certain to write the additional refrigerant amount, pipe length (actual length), head and other specification on the nameplate put on the outdoor unit for recording. Seal the correct amount of additional refrigerant in the system. 3 500mm or more Horizontal <Formula for Calculating Additional Refrigerant Amount> Do not remove the refrigerant even if the additional refrigerant amount becomes minus as a result of calculations by the following formula and operate the air conditioner as it is. Additional refrigerant amount (kg) = Main piping additional refrigerant amount (kg) + Branch piping additional refrigerant amount (kg) = A×(L-18)+B×(a+b-4) A: Additional refrigerant amount per meter of actual main piping length (kg) B: Additional refrigerant amount per meter of actual branch piping length (kg) L: Actual length of main piping (m) Indoor Unit B Main piping Outdoor Unit a, b: Actual length of branch piping (m) Model (RAV) Standard piping length Main piping Branch piping 2m Additional refrigerant amount per Meter (kg/m) A 0. 040 0. 040 B 0. 020 0. 040 Branch piping Branch pipe Branch piping Indoor Unit A SM1100AT-E SM1400AT-E 18m Gas Leak Test Use a leak detector manufactured specially for the HFC refrigerant (R410A, R134a, etc. ) when testing R410A. * The sensitivity of leak detectors for previous HCFC refrigerants (such as R22) lowers to about 1/40 when used with HFC refrigerants and these detectors cannot be used. <<High wall>> Electrical Wiring Be certain to install wires by connecting them to terminals of the same numbers according to the following wiring diagram. Incorrect wiring will result in a failure. Exercise reasonable caution with the following when installing wires. No. 1 2 3 4 Item Remote control wiring Main circuit wiring Indoor unit No. setting Selector Switch Setting Description (1) Connect the remote controller only to the main unit. (2) Install wires to B and C only between the main unit (Unit A) and sub unit (Unit B). (3) Disconnect Connector CN12 of the sub unit (Unit B). Connect wires of the main circuit from the outdoor unit, main unit (Unit A) and sub unit (Unit B) correctly. (Wires of (1), (2) and (3)) Set the rotary switches on the control printed circuit board of the indoor unit to 1 and 2 for the main unit (Unit A) and sub unit (Unit B). Set the selector switch (SW05-1) on the printed circuit boards of the indoor units to ON.
