Startup and Commissioning

Operation

For new installations, ensure the unit is ready to operate
by going through the Checklist for Completed Installation,
located in Appendix A, prior to start-up.
Note: A Warranty Registration and Start-Up Checklist is
provided with the unit data package. It should be
completed during start-up and sent to Trane. This
checklist should be used as a guideline for items
that need to be confirmed during start-up.
Test cooling operation by adjusting the temperature
setpoint at the system controller. The compressor should
come on and the suction line temperature should
gradually drop.
Ensure the fan(s) are rotating correctly and freely without
any unusual noise.
Note: Start-up must be performed by a qualified
journeyman, refrigeration mechanic or an air
conditioning technician. Refer to the separate
controller operation instructions sent in the data
package with your unit.

Operational Description

When used with a Trane indoor evaporator unit, the A/C
system compressor starts then the condenser fan(s) start.
Operation of the condenser fans is dependent on the head
pressure control method used.
Remote air-cooled condensers may be configured for
stand-alone operation. In this case the fans begin
operating when power is turned on.
Refrigerant flowing from the evaporator in the form of a
low pressure gas, enters the compressor where it is
compressed into a high temperature, high pressure gas.
