FILLING THE CIRCUIT SYSTEM
If the pressure is too low in the CIRCUIT system, it needs to be topped up. See the Installer Manual for more information.
VENTING THE CIRCUIT SYSTEM
In event of repeated
fi
lling of the CIRCUIT system, or if bubbling sounds are heard from the indoor module, the system may
need venting. This is done as follows:
1. Turn off the power supply to the indoor module.
2. Vent the indoor module via the vent valves and the rest of the climate system via the relevant vent valves.
3. Keep topping up and venting until all air has been removed and the pressure is correct.
The climate system may require topping up after venting.
In rare cases,
fl
ammable gas may be mixed in, so when venting, keep ignition sources away and ventilate well.
