After determining the approximate charge using the above tables, refer to “System Performance Chart” (Table 8-5)
to determine if the correct charge has been obtained.
The data listed in Table 8-1 trough Table 8-3 is based on a 20 foot liquid line. Increase the charge by 0.5 pound for each
additional 10 feet of liquid line.
8.1.5 Evaporator Tie-In.
When an after market in-dash evaporator is added to a standard system the refrigerant charge will increase by
approximately 1 pound.
If attempting to use a CM-2 condenser with a tie-in call Carrier Transport Air conditioning technical support for an
application review.
