NOTE
•
Where a single refrigerant facility is divided into 2 entirely indepen-
dent refrigerant systems then use the amount of refrigerant with
which each separate system is charged.
2.
Calculate a room volume (ft
3
)
3.
Calculate the refrigerant concentration by using the results of the
calculations in steps 1 and 2 above.
4.
Deal with the situations where the result exceeds the maximum con-
centration level.
Where the installation of a facility results in a concentration in excess
of the maximum concentration level then it will be necessary to revise
the system.
Please consult your dealer.
