10.3 Initial start-up at low outdoor ambient temperature
During initial start-up and when water temperature is low, it is important that the water is heated gradually. Failure to do so
may result in concrete floors cracking due to rapid temperature change. Please contact the responsible cast concrete building
contractor for further details.
To do so, the lowest water flow set temperature can be decreased to a value between 25°C and 35°C by adjusting the FOR
SERVICEMAN. Refer to "FOR SERVICEMAN/special function/preheating for floor".
10.4 Pre-operation checks
Checks before initial start-up.
Switch off the power supply before making any connections.
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 9.6 Field wiring, according to the wiring diagrams
and to local laws and regulations.
•
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.
•
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.
•
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).
•
Ground wiring: Make sure that the ground wires have been connected properly and that the ground terminals are
tightened.
•
Internal wiring: Visually check the switch box for loose connections or damaged electrical components.
•
Mounting: Check that the unit is properly mounted, to avoid abnormal noises and vibrations when starting up the unit.
•
Damaged equipment: Check the inside of the unit for damaged components or squeezed pipes.
•
Refrigerant leak: Check the inside of the unit for refrigerant leakage. If there is a refrigerant leak, call your local dealer.
•
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.
•
Air purge valve: Make sure the air purge valve is open (at least 2 turns).
•
Shut-off valves: Make sure that the shut-off valves are fully open.
