Field wiring guidelines

Most field wiring on the unit is to be made on the terminal block
inside the switch box. To gain access to the terminal block,
remove the switch box service panel (door 2).
Cable tie mountings are provided at the bottom of the switch
box. Fix all cables using cable ties.
A dedicated power circuit is required for the backup heater.
Installations equipped with a domestic hot water tank (optional),
require a dedicated power circuit for the booster heater.
Please refer to the domestic hot water tank installation manual.
