Charge additional refrigerant calculated by the equation &
table in Step 1.
After the refrigerant charge has bled into the indoor unit,
open the liquid service valve. The service valve cap is the
secondary seal for the valves and must be properly tightened
to prevent leaks. Make sure cap is clean and apply refrigerant
oil to threads and sealing surface on inside of cap. Tighten
cap finger-tight and then tighten additional 1/6 of a turn to
properly seat the sealing surfaces.
Break vacuum by fully opening liquid and suction base valve.
NOTE: 1.5 - 3.0 ton have front seating valves. 3.5 - 5.0 ton
have front / back seating valve. Refer detail function on page
17. It is not necessary to force the stem tightly against the
rolled lip.

A system test is now required to check the equipment
settings and functionality. Once selected, it checks the
equipment for approximately 10 - 15 minutes. System test
may exceed 15 minutes if there is an error. Refer to the
Troubleshooting section, if error code appears.
Before starting the SYSTEM TEST, turn off the electric
heater or gas furnace.
NOTE: Ensure the thermostat is in OFF. Choose "OFF" before
"CHARGE MODE".

Et thErMostat to chargE ModE
If required additional charging amount cannot be charged
to the system without operation, then use this "CHARGE
MODE".
When adjusting "Sub cooling", use this "CHARGE MODE".
CHARGE MODE allows for charging of the system. System
operates for a duration of approximately two hours while
the equipment runs at full capacity. After two hours, the
CHARGE MODE ends and the system resumes normal
thermostat operation.
Before starting the CHARGE MODE, turn off the electric
heater and finish SYSTEM START-UP TEST.
NOTE: Charging equipment must use dedicated PVE oil
gauges and hoses.
1. Purge gauge lines.
2. Connect service gauge manifold to liquid base valve
service ports.
3. Convert the liquid pressure to temperature using a
temperature/pressure chart.
4. Temporarily install a thermometer on the liquid line at
the liquid line service valve.
Ensure the thermometer makes adequate contact and
.
is insulated for best possible readings.
5. Subtract the liquid line temperature from the converted
liquid pressure to determine subcooling.
6. Before starting the subcooling adjustment, make sure the
outdoor ambient temperature is in the range shown in
charging table and the unit is operating at 100% capacity.
When the unit is ready for charging, the seven segment
display will show "cha" and current subcooling value
alternately.
When the outdoor ambient temperature is 65°F-105°F,
the seven segment display will show current subcooling
value.
7. If the system subcooling is not within the range
as shown in the charging table, adjust subcooling
according to the following procedure.
• If subcooling is low, add charge to adjust the sub-
cooling as specified in the following table.
• If subcooling is high, remove charge to adjust the
subcooling as specified in the following table.
NOTE: The seven segment display can keep flashing "cha"
in charge mode when the system is not in condition. Then
subcool adjustment is not available. Please complete charg-
ing following STEP1 and 2.
NOTE: To achieve rated performance, measure subcooling
using a pressure gauge and temperature sensor.
