2. After the compressor and condenser fan have
started and operated for approximately 30 minutes,
observe the operating pressures. Compare the
operating pressures to the operating pressure curve
in the Service Facts.
3. Check system subcooling. Follow the instruction
listed on the subcooling charging curve in the
Service Facts.
4. Repeat Step 1 through Step 3 for each refrigerant
circuit.
5. To stop the SERVICE TEST, turn the main power
disconnect switch to the “Off” position or proceed
to the next component start-up procedure. Remove
electromechanical test mode connections (if
applicable).
Heating Start-Up
1. Clamp an amp meter around one of 1
st
stage heater
power wires at the heater contactor.
2. Verify that the heater stage is operating properly.
3. Clamp an amp meter around one of 2
nd
stage
heater power wires at the heater contactor (if
applicable).
4. Verify that the heater stage is operating properly.
5. To stop the SERVICE TEST, turn the main power
disconnect switch to the “Off” position or proceed
to the next component start-up procedure. Remove
electromechanical test mode connections.
Final System Set Up
After completing all of the pre-start and startup
procedures outlined in the previous sections (i.e.,
operating the unit in each of its modes through all
available stages of cooling and heating), perform these
final checks before leaving the unit:
☐ Program the Night Setback (NSB) panel (if
applicable) for proper unoccupied operation. Refer
to the programming instructions for the specific
panel.
☐ Verify that the Remote panel “System” selection
switch, “Fan” selection switch, and “Zone
Temperature” settings for automatic operation are
correct.
☐ Inspect the unit for misplaced tools, hardware, and
debris.
☐ Verify that all exterior panels including the control
panel doors and condenser grilles are secured in
place.
☐ Close the main disconnect switch or circuit
protector switch that provides the supply power to
the unit’s terminal block or the unit mounted
disconnect switch.
