onto the conduit mounting plate.
2) Strip wire ends (3/4 inch (20mm)).
3) Match wire colours with terminal numbers on indoor and outdoor unit's terminal blocks and firmly secure the wires in
the corresponding terminals with the screws.
4) Connect the ground wires to the corresponding terminals.
5) Pull the wires lightly to make sure they are securely connected.
6) Make sure that the wires do not come in contact with the metal conduit for the heat exchanger.
7) In case of connecting to an adapter system. Run the remote controller cable and attach the S21. (Refer to "11� When
