8.5.3 AIR HANDLER WITH CIRCUIT BREAKER
HEAT KIT
The circuit breakers have lugs for power supply connection. See
the HKS Installation Instructions for further details.
• Use only specified wire and connects to terminals tightly. Be
careful that wires do not place external stress on terminals.
Keep wire in neat order; not to obstruct other equipment.
Make sure that the access panel closed tightly. Incomplete
connections could result in overheating, and in worse cases,
electric shock or fire.
• Never connect power supply wiring to the terminal block for
remote controller wiring as this could damage the entire
system.
• When doing the wiring, make sure the wiring is neat and
does not cause the access panel to stick up, and then close
the cover firmly. When attaching the electric component box
cover, make sure you do not pinch any wires.
PRECAUTIONS
• Refer to the "REMOTE CONTROLLER INSTALLATION
MANUAL" on how to install and lay the wiring for the remote
controller.
• See also the "Wiring Diagram Label" located inside the unit's
fan housing.
• Connect the remote controller and transmission wiring their
respective terminal blocks.
