Installation of outdoor unit
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.
1.
Calculate the amount of refrigerant (lb.) charged to each
system separately.
amount of refriger-
ant in the unit
(amount of refriger-
ant with which the
system is charged
before leaving the
factory)
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.
2.
Calculate a room volume (ft³)
3.
Calculate the refrigerant concentration by using the results
of the calculations in steps 1 and 2 above.
total amount of refrigerant in the
system
volume (ft³) of the room in which there
is an indoor unit installed
4.
Deal with the situations where the result exceeds the
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.
