Pre-Start Checklist
After the unit is installed, complete each step in the
checklist that follows and check off each step as
completed. When all are accomplished, the unit is
ready to be started.
☐
Inspect all wiring connections. Connections should be
clean and tight.
☐ Check voltage to the unit at the line power fused
disconnect. Voltage must be within the voltage utilization
range given on the unit nameplate. Voltage imbalance
must not exceed two percent. Refer to the “Voltage
Imbalance,” p. 20
.
☐
Check condenser fans. Condenser fan blades should
rotate freely in the fan orifices and should be mounted
securely on the motor shafts.
☐ Check condenser coils. Coil fins should be clean and
straight. There should be no restrictions to proper airflow
through the condenser.
☐ Evacuate the refrigerant system. See Maintenance chapter
of unit IOM (SSCCXXFF--SSVVXX0011**--EENN or SSCCXXGG--SSVVXX0011**--EENN for
evacuation and procedure.
☐ Once the system is properly evacuated, charge each
circuit with proper amount of refrigerant.
☐ Refer to the Mechanical and Start-up sections in the
Installation, Operation, and Maintenance Manuals (SSCCXXFF--
SSVVXX0011 and or SSCCXXGG--SSVVXX0011 for refrigerant charging
procedures).
☐ Prepare remainder of system for operation and
coordinate condenser start up with evaporator unit
startup.
