Check system operation:
o
The outdoor unit is pre-charged at the factory so no additional adjustment
to refrigerant charge is required if line set is at design length or less.
o
Additional charge must be weighted in per the following table.
Model Design
Length oz. per ft. over
Design Length
MS29A13115A, 9A23YGX 26.25 ft. 0.32
MSC49HP13115A, 9H43YGX 16.4 ft. 0.3
MS212A13115A, 12A23YGX 26.25 ft 0.32
MSC412HP13115A, 12H43YGX 16.4 ft 0.3
MS212A13240A, 12A23ZCX 26.25 ft. 0.32
Example: If installation is a MSC49HP13115A and the line set is 26.4 feet long.
That would be 10 ft. over design length. Multiply 10 ft. X 0.3 oz./ft. = 3 oz. extra
refrigerant needed for this installation.
o
After installation the pressure reading should be as indicated below in the
charts.
o
This pressure is taken from the suction side service port.
o
Using the pressure / temperature chart below correct refrigerant level as
necessary.
o
If outdoor temperature is not within the temperature range of the graph
below then proper refrigerant pressure cannot be calculated accurately.
