EXAMPLE OF CONNECTION REQUIRING ADDITION OF R407C
REFRIGERANT
NOTA:
The R407C refrigerant charge value is given for 4 m pipe length .
For longer pipe lengths the amount of charge to be added is
15g/m for each way15g/m for each way
15g/m for each way15g/m for each way
15g/m for each way
CIRCUIT A (U1-A)
The additional quantity of R407C will be:
+ 165 g (15m pipe lengths)
being, in this example, an increase of 255 g for circuit A,
and
CIRCUIT B (U2-B / U3-B)
+ 165 g (15 m pipe lengths)
+ 15 g (5 m pipe lengths)
being, in this example, an increase of 180 g for circuit B,

This operation must only be performed by qualified personnel, in accordance with
refrigeration engineering best practices.
The values in the example of connection for these pipe lengths require the addition of R407C
refrigerant on site. Any interventions on the refrigeration circuits must be performed in strict
compliance with CECOMAF GT1-001 recommendations (recommendations on R407C
emissions into the atmosphere).
