4 SAFETY CA UTION The impor tant contents concer ned to the safety are described on the product itself and on this Ser vice Manual. Please read this Ser vice Manual after understanding the described items thoroughly in the follo wing contents (Indications/Illustrated marks), and keep them.
5 Before tr oubleshooting or repair w ork, check the earth wire is connected to the earth terminals of the main unit, otherwise an electric shock is caused when a leak occurs. If the ear th wire is not correctly connected, contact an electr ic engineer for re wor k.
6 After the w ork has finished, be sure to use an insulation tester set (500V mugger) to chec k the resistance is 2M Ω Ω Ω Ω Ω or more between the char g e section and the non-charge metal section (Earth position). If the resistance v alue is low , a disaster such as a leak or electr ic shock is caused at user ’ s side.
7 • Ne w Refrigerant (R410A) This air conditioner adopts a new HFC type refrigerant (R410A) which does not deplete the oz one lay er. 1 . Safety Caution Concerned to New Refrigerant The pressure of R410A is high 1.6 times of that of the f o rmer refrigerant (R22).
8 5 . Recharge of Refrigerant When recharge of the refrigerant is required, charge the new refrigerant with the specified amount in the procedure as described below . Q Ne v er charge the refrigerant ov er the specified amount. R Do not charge the additional refrigerant.
9 1. OUTLINE “ Super Heat Recovery Multi System ” is a multi air conditioning system whic h enables eac h indoor unit in a refrigerant line to independently select cooling or heating operation. As it is able to operate sim ultaneously in cooling and heating modes, fur ther heat recovery becomes possible.

89 8-4-3. Address Setup Procedure In this air conditioner , it is required to set up address to the indoor unit bef ore starting opera- tion. Set up the address accor ding to the follo wing setup procedure. CA UTION 1. Set up address after wiring work.
90 8. How to set up the terminal resistance When all the address setups hav e finished in the same refr iger- ant circuit system, put the terminal resistance in the same central control line into one . • Remain only SW30-2 of the header outdoor unit with address 1 as ON.
91 Note 1) When setting the line address from the remote controller , do not use address 29 and 30. The address 29 and 30 cannot be set up in the outdoor unit. Theref ore if they are incorrectly set up , a check code [E04] (Indoor/outdoor communication circuit error) is output.
92 • T o change all the indoor addresses from an arbitrary wired remote controller; (When the setup operation with automatic address has finished, this change is a v ailable.
93 In case of increase the address-undefined indoor units (Extension, etc.) If set up the indoor address of which address is undefined accompanied with e xtension of indoor units , replace- ment of P .C . board, etc, follo w to the methods below . Method 1 Set up an address individually from a wired remote controller .
94 8-5. T r oub leshooting in T est Operation If the phenomena appear , such as a check code is output or the remote controller is not accepted in po wer-ON after cab ling w o rk or in address setup operation, the f ollo wing causes are considered. 8-5-1.
