START-UP
Checks before initial start-up
Pre-operation checks
Switch off the power supply before making any connections .
After the installation of the unit, check the following before switching on
the circuit breaker:
1 . Field wiring
Make sure that the field wiring between the local supply panel and unit
and valves (when applicable), unit and room thermostat (when appli-
cable), unit and domestic hot water tank, and unit and backup heater
box have been connected according to the instructions described in the
chapter 9 .6 Field wiring, according to the wiring diagrams and to local
laws and regulations .
2 . Fuses, circuit breakers, or protection devices
Check that the fuses or the locally installed protection devices are of the
size and type specified in the chapter 14 Technical specifications. Make
sure that no fuses or protection devices have been bypassed .
3 . Backup heater circuit breaker
Do not forget to turn on the backup heater circuit breaker in the
switchbox (it depends on the backup heater type) . Refer to the wiring
diagram .
4 . Booster heater circuit breaker
Do not forget to turn on the booster heater circuit breaker (applies only
to units with optional domestic hot water tank installed) .
5 . Ground wiring
Make sure that the ground wires have been connected properly and
that the ground terminals are tightened .
6 . Visually check the switch box for loose connections or damaged
electrical components .
7 . Mounting
Check that the unit is properly mounted, to avoid abnormal noises and
vibrations when starting up the unit .
8 . Damaged equipment
Check the inside of the unit for damaged components or squeezed
pipes .
9 . Refrigerant leak
Check the inside of the unit for refrigerant leakage . If there is a refrige-
rant leak, call your local dealer .
10 . Power supply voltage
Check the power supply voltage on the local supply panel . The voltage
must correspond to the voltage on the identification label of the unit.
11 . Air purge valve
Make sure the air purge valve is open (at least 2 turns) .
12 . Shut-off valves
Make sure that the shut-off valves are fully open
WARNING
When power to the unit is turned on, "1%~99%" is displayed on the user interface during initialization . During this process
the user interface cannot be operated .
Powering up the unit
Before switching on the unit, read following recommendations:
■ When the complete installation and all necessary settings have been carried out, close all front panels of the unit and refit the
unit cover .
■ The service panel of the switch box may only be opened by a licensed electrician for maintenance purposes.
Final check
The DIP switch are located on the hydraulic module control board inside the unit's electrical panel (for more details see also
MAINTENANCE AND SAFETY section) . These allow you to specify whether the system includes the electric booster (IBH), the
boiler (AHS) .
Switch off the power supply before opening the switch box service panel and making any changes to the
DIP switch settings .
