10. Start-Up Pre-Start Quick Check List

• Is unit level and located with proper clearances?
• Is the duct work correctly sized, run, taped, insulated and
weather proofed with proper unit arrangement?
• Is condensate line properly sized, run trapped and pitched?
• Is the filter of the correct size, clean and in place?
• Is the wiring properly sized and run in according to the unit
wiring diagram?
• Are all wiring connections tight including those in unit and
compressor electrical boxes?
• Has the unit been properly grounded and fused with the
recommended fuse size?
• Is the remote controller correctly wired and in a good
location?
• Have the air conditioning systems been checked at the
service ports for charge and leak tested if necessary?
• Does the condenser fan and indoor fan turn freely without
rubbing and are they tight on the shafts?
• Visually inspect the unit to ensure that the airflow required
for the condenser coil is not obstructed from the unit.
• Inspect the control panel wiring to verify that all electrical
connections are tight, and that wire insulation is intact.
• Is the indoor fan and rotation correct?
• Has the indoor fan speed been determined and the proper
speed been set?
• Has all work been done in accordance with applicable local
and national codes?
• Are all covers and access panels in place to prevent air loss
and safety hazards?
WARNING
Bodily injury can result from high voltage electrical components. If operating checks must be
performed with the unit operating, it is the technician's responsibility to recognize these hazards
and proceed safely. Failure to do so could result in severe personal injury or death due to
electrical shock or contact with moving parts.
Power-up Initialization
The "initialization" by the MAIN CONTROLLER occurs each time the system is powered-up.
the MAIN CONTROLLER performs internal self-diagnostics checks, which include
identifying the equipment components of its system, and the configuring of itself to that
system. It also checks itself to be sure it is functioning correctly.
