(Factory charge for Itneset - 0 oz / 268.16 g)
5/16

027 (7.80)
Units are factory charged for 15 ft (4.6 m) of 3/8" liquid line. The factory charge for 3/8" lineset 9 oz.(266.16 g). When using other length
or diameter liquid lines, charge adjustments are required per the chart above.
Chareina Formals:
[(Lineset oz/ft x total length) - (factory charge for lineset)] = charge adjustment
Example 1: System has 15 ft of line set using existing 1/4" liquid line. What charge adjustment is required?
Formula: (.27 oz/ft x 15ft) - (9 oz) = (4.95) oz.
Net result is to remove 4.95 oz of refrigerant from the system
Example 2: System has 45 ft of existing 5/16" liquid line. What is the charge adjustment?
ForFnula: (.40 oz/ft, x 45ft) - (9 oz.) = 9 oz.
Net result is to add 9 oz of refrigerant to the system
NOTE: Conditions must be favorable for charging by subcooling method. Indoor temperature must be 70°F to 80°F (21.1°C to 26.7°C�
and outdoor temperature must be 700F to 100°F (21.1 °C to 37.8*C). If outside these conditions, adjust charge for long line sets by weigh-in
method.
