After the installation of the unit, check the following before switching on the circuit breaker:
 Field wiring: Make sure that the field wiring between the local supply panel and unit and valves
(when applicable), unit and room thermostat (when applicable), unit and domestic hot water tank,
and unit and backup heater kit have been connected according to the instructions described in the
chapter 7 "Field wiring", according to the wiring diagrams and to local laws and regulations.
