Atlantic alfea extensa + - 3.4.5 Additional charge

3.4.5 Additional charge
The charge in the outdoor units corresponds to the maximum distances between the outdoor unit and the hydraulic
unit dened in page 21. If the distances are greater, an additional charge of R410A is required. The additional
charge depends on the distance between the outdoor unit and the hydraulic unit for each type of appliance.
The additional charge of R410A must necessarily be made by an approved refrigeration engineer.

gure 26 - "Gas" bottle R410A
Liquid
Gas
- The charge must be introduced after creating the
vacuum and before the hydraulic unit is lled with gas,
as follows :
- Disconnect the vacuum pump (yellow hose) and connect a
bottle of R410A instead 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 charge, close the
bottle and disconnect it.
- Then rapidly disconnect the hose connected to the appliance.
- Proceed to ll the hydraulic unit with gas.
" Warning
• Only use R410A !
• Only use tools suitable for R410A (set of manometers).
• Always charge in the uid phase.
• Never exceed the length or the maximum difference in level.
