Pay a special attention to the place, such as a basement,
etc. where refrigerant can stay, since refrigerant is heavier
than air.
Procedure for checking maximum concentration
Check the maximum concentration level in accordance with
steps 1 to 4 below and take whatever action is necessary to
comply.
Calculate the amount of refrigerant (lb.) charged to each
1.
system separately.
amount of refriger-
ant in the unit
(amount of refriger-
ant with which the
system is charged
before leaving the
factory)
+
additional charging
amount (amount of
refrigerant added
locally in accordance
with the length or
diameter of the
refrigerant piping and
type of indoor unit)
=
total amount
of refrigerant
(lb.) in the
system
NOTE
Where a single refrigerant facility is divided into 2 entirely
•
independent refrigerant systems then use the amount of
refrigerant with which each separate system is charged.
Calculate a room volume (ft³)
2.
Calculate the refrigerant concentration by using the results
3.
of the calculations in steps 1 and 2 above.
total amount of refrigerant in the
system
≤
maximum concentration
level (lb./ft³)
volume (ft³) of the room in which there
is an indoor unit installed
Deal with the situations where the result exceeds the
4.
maximum concentration 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.
