3.4.5 Additional lling
The amount needed to ll the outdoor units corresponds to the maximum distances between the outdoor unit and the
hydraulic unit as dened here page 22. If the distances are greater, an additional amount of R410A is required.
For each type of appliance, this additional amount depends on the distance between the outdoor unit and the
hydraulic unit. Any additional lling with R410A must be carried out by an approved specialist.

Filling must be carried out after creating a vacuum and
before gassing the hydraulic unit, as follows:
- Disconnect the vacuum pump (yellow hose) and
connect a bottle of R410A in its place in the uid
extraction position.
- Open the bottle’s valve.
- Bleed the yellow hose by loosening it slightly on the
Manifold side.
- Place the bottle on scales with a minimum accuracy of
10g. Note the weight.
- Carefully open the blue valve slightly and check the
value shown on the scales.
- As soon as the value displayed has dropped by the
value for the calculated additional ll amount, close the
bottle and disconnect it.
- Quickly disconnect the hose connected to the
appliance.
- Proceed to ll the hydraulic unit with gas.
