• Keep a margin (Approx. 100 mm) on a wire to hang down the electrical control box at servicing or other purpose.
• The low-voltage circuit is provided for the remote controller. (Do not connect the high-voltage circuit)
• Remove the front panel of the hot water module by taking off the mounting screws (2 positions).
• Tighten the screws of the terminal block, and fix the wires with cord clamp attached to the electrical control box.
(Do not apply tension to the connecting section of the terminal block.)
