A single OUTDOOR unit enables air conditioning of up to four separate rooms

Remarks:

 1. At least two indoor units must be connected.
 2. The total nominal cooling capacity of indoor units that will be connected to outdoor unit must be within connectable

capacity range of outdoor unit. (Shown in the above table)

Example: The below indoor units combination is not possible to connect CU-3E23CBPG. (Total nominal capacity
of indoor unit is between 5.0kW and 10.0kW)
1) Two CS-ME7CB1P only. (Total nominal cooling capacity is 4.4kW)
2) Three CS-ME14CB1P only. (Total nominal cooling capacity is 12.0kW)

Lead - free P.C. Board

2 About Lead Free Solder (PbF)

2.1. DISTINCTION OF PbF P.C. BOARD

P.C. Boards (manufactured) using lead free solder will have a PbF stamp on the P.C. Board.

2.2. CAUTION

    

·

    

Pb free solder has a higher melting point than standard solder; Typically the melting point is 50 - 70 °F (30 - 40 °C) higher.
Please use a high temperature solder iron and set it to 700 ± 20 °F (370 ± 10 °C).

    

·

    

Pb free solder will tend to splash when heated too high (about 1100 °F/ 600 °C).

If you must use Pb solder, please completely remove all of the Pb free solder on the pins or solder area before applying Pb
solder. If this is not practical, be sure to heat the Pb free solder until it melts, before applying Pb solder.
