Additional fi lling
The amount needed to fi ll the outdoor units corresponds to the maximum distances between the outdoor unit and
the hydraulic unit as defi ned here page 26. If the distances are greater, an additional amount of R32 is required.
For each type of appliance, this additional amount depends on the distance between the outdoor unit and the
hydraulic unit. Any additional fi lling with R32 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 R32 in its place in the liquid
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 fi ll amount, close the
bottle and disconnect it.
- Quickly disconnect the hose connected to the
appliance.
- Proceed to fi ll the hydraulic unit with gas.
Only use R32 !
Only use tools suitable for R32
(set of pressure gauges).
Always fi ll in the liquid phase.
Never exceed the maximum length or
diff erence in level.
