corresponding terminals.
4) Connect the ground wires to the corresponding terminals.
5) Pull wires to make sure that they are securely latched up.
6) In case of connecting to an adapter system. Run the remote control cable and attach the S21.

shock, or fire.
• Do not use locally purchased electrical parts inside the product. (Do not branch the power for the drain pump, etc., from the
terminal block.) Doing so may cause electric shock or fire.
• When carrying out wiring connection, take care not to pull at the conduit.
