Charging; Air Handler Capacity - Coleman LX Series Technical Manual

2. A TXV kit must be used with these indoor units to obtain system performance.
3. Systems matched with furnaces or air handlers not equipped with blower-off delays may
require blower time delay.
4. Do not use XAF/XAU coils in horizontal applications. Do not use XAH coils in upflow/downflow
applications.
5. Charge adders shown above do not indicate that coils are rated for every application. Refer
to the Performance data tables for actual performance for specified system matches. Obtain
certified system ratings from http://www.ahridirectory.org.

Charging

1. Check the factory unit charge listed on the unit nameplate to verify the refrigerant charge
for the outdoor unit, the smallest matched indoor unit, and the 15 ft of interconnecting
refrigeration piping.
2. Verify the indoor metering device and additional charge required for the specific matched
indoor unit in the system using Table 4 or Table 5.
3. Add additional charge for the amount of interconnecting refrigeration piping greater than 15
ft at the rate specified in Table 2.
4. For installations requiring additional charge, weigh in refrigerant for the specific matching
indoor unit and actual refrigeration piping length.
5. After weighing in the charge adders for the matched indoor unit and refrigeration piping,
verify the system operation against the temperatures and pressures in the charging chart
for the outdoor unit. Locate the charging charts on the outdoor unit and in the Service Data
Application Guide on www.simplygettingthejobdone.com. Follow the subcool or superheat
charging procedure in the Installation Manual according to the type of indoor metering device
in the system, and allow 10 min after each charge adjustment for the system operation to
stabilize. Record the charge adjustment made to match the charging chart.
6. Permanently stamp the unit nameplate with the total system charge defined as follows: total
system charge = base charge (as shipped) + charge adder for matched indoor unit + charge
adder for actual refrigeration piping length + charge adjustments to match the charging
chart.
